Excellent Solution to Fiber Patch Cable Management

by http://www.fiber-mart.com

Recently I saw many people be in trouble in fiber patch cable management, usually see them stack the cables casually, many people will have the feeling of a mess and always envy other people can do it well, maybe today’s article can give you a lot of help and don’t have to be jealous of other people’s good work.
The optical cord has the possibility to be the weakest link in the fiber optic network, usually in order the finish optimum performance and reliability we must observe true procedures in the administration of the fiber patch cords, the best solution will be the smallest cost and changes or moves. In the fiber patch cable management, the voice connection should be also careful. Well, let’s tell you detailed procedures.
When we receive the request from the administration, be sure that you know the introduction and design of the fiber cabling and you should also know that if you have fiber patch cords that can match to the stalled cabling, the reason is that fiber optic cables have different types and they should be distinguished. Then choose the suitable length of fiber cable. The length depends on its points of connection. It is the shortest one that does not obstruct or interfere with other cords and connectors on the fiber patch panels, avoiding running cords and connectors on the panel. The next step is that tight the fiber patch cords, it will be pulled on connectors and too much slack complicates cable management, making the fiber patch panel more difficult to operate in. At the fiber patch panel, the patch cables equally toward both sides of the vertical cable management channels to prevent overloading one side. Be careful not to mix up cords of different core diameters. Additionally, cords must be of the same or higher bandwidth as the behind-the-wall cabling. Before the patching, there is a point we need to remember, it is cleaning the connector, the cleaning parts include connector ends on patch cords, connector ends on panels, connector ends on network equipment, as for how to clean different types of the fibre optic connector, such as fibre optic sc connector, fibre optic lc connector…We mentioned it in our Fiberstore’s blog if you are interested in it, welcome to visit Fiberstore’s blog. For example, exceeding the bend radius can result in significant additional loss and adverse impact on channel performance. For example, mpo fiber, the minimum bend radius is ten times the core diameter. Take care not to use excessive force during the patching process. This can stress cords and connectors, reducing their performance. If you need to go to force in pulling a cord, something is wrong. If the existing core is the right length, it may be possible to re-use it. If this is the case, remove the cord completely and re-run it in through the cable pathways. This is the only guaranteed way to ensure there are no tangles, kinks or strains in the cord. The final step is to update the documentation of the as-built configuration and close the work order associated with the completed change request.
The above contents are the summary of fiber patch cable management steps, if there are some trouble when you are putting into the practice, welcome to discuss with us, and the related fiber optics that I mentioned in this page, such as various of fiber cables, fiber connectors, fiber adapters even fiber optic patch panel, you all can find from fiber-mart.COM.

How Many Choices Do You Still Have for Fiber Patch Cable?

by http://www.fiber-mart.com

Fiber patch cable, also known as fiber jumper, is a key component in today’s fiber optic network. They play the role of veins in the whole fiber optic network bringing fiber optic signals between devices.
During the selection of standard fiber patch cables, several questions are usually take into consideration:
What’s the fiber type of the patch cable? The available selection are Multimode (OM1, OM2, OM3, OM4) and single-mode (OS1 and OS2).
What’s the connector type and connector polishing type on the two ends of fiber patch cable? Currently the most commonly used fiber patch cables are usually terminated with LC, SC and MPO connectors.
What’s the fiber count of the patch cable? Simplex (one fiber) and duplex (2 fibers) fiber patch cable are very common. For fiber patch cables terminated with MTP/MPO connector or breakout fiber patch cables. Their fiber count would be larger, sometime up to 24 fibers or more.
What’s the material of the fiber patch cable jacket? PVC, LSZH, Armored, and OFNP are the choice of most situations.
Not All Fiber Patch Cable Are Created Equal
Now with the fiber optic cable being widely used in a variety of industries and places, the requests for fiber patch are being refined. Fiber patch cable are being required to be improved and provide more possibilities to satisfy various application environments. Actually, many specially fiber patch cable have been created to answer the market call. Here will introduce several unique but useful fiber patch cable for your references.
Bend Insensitive Fiber Patch Cable for Lower Signal Loss
Bend loss issues are always a headache problem for most fiber optic network designers and installers. Why? Cause signal loss caused by bend loss issues are really hard to handle. In addition the bend loss issues are difficult to locate. That’s why bend insensitive fiber patch cables are created. Literally, it tells us that this type of fiber patch cable is not as sensitive as other fiber patch cables. The secrets is lays on the fibers which is made of bend insensitive glass. More and more data centers and FTTH systems are tend to use these bend insensitive fiber patch cables, because they do not provide lower signal loss, but also provide a much more durable and easy to maintain networking environment. Fiber optic installer is able to save installation cost with faster installation due to easier fiber optic cable handling.

Keyed LC Fiber Patch Cable for Data Security
Keyed LC fiber patch cable, is also called secured LC fiber patch cable. This is because, the fiber optic connectors on the two end of the patch cable are specially designed LC connectors, which can ensure the data security at the mechanic level. Keyed LC fiber patch cable is identifies by the connector color. Keyed LC fiber patch cable is just a part of the Keyed LC connectivity product family. It should be used with the same colored fiber adapters or fiber adapter panels. Each color of a set of keyed LC connectivity products represents a unique keying pattern that only allows matched color mating. This is how keyed LC fiber patch cable can provide data security for fiber optic network. A previous article (Secure Fiber Optic Link With Keyed LC Connectivity Products) of my has introduce keyed LC connectivity in details, kindly follow the link on the article title if you need more information about them.

Uniboot LC Fiber Patch Cable for Easier Cable Management
Uniboot LC fiber patch cable is a fiber patch cable with two fibers wrapped in the same strand of cable. A duplex LC fiber optic connector which can provide easy polarity reversal is terminated on each end of the uniboot LC fiber patch cable. The following picture show the polarity reversal of a typical uniboot LC fiber patch cable. With less cabling space are require, better cooling is available. With easier polarity reversal, no additional tools are required. And easier cable management can be enjoyed.

HD TAB Fiber Patch Cable for Space Saving
HD (high density) TAB fiber patch cable is a fiber patch cable with its connectors attached with a push pull tab, which can provide easier finger access and cable locating. Today’s fiber optic network is increasing depended on high density which results in difficult finger access and difficult cable management. With a push-pull tab attached on the connector, problem are solved easily. The connecting and disconnection of fiber patch cables will be easier without affecting other surrounding links. Currently most HD TAB fiber patch cables available the market are terminated with LC and MTP/MPO connectors.

How To Choose The Right Fiber Patch Cable ?

There are many different types of fiber optic cable. Fiber-Mart stocks hundreds of varieties and we can custom build thousands of other types. The sheer number of options can be overwhelming to people that don’t work with fiber optic cable regularly. So here are some common questions. 

There are many different types of fiber optic cable. Fiber-Mart stocks hundreds of varieties and we can custom build thousands of other types. The sheer number of options can be overwhelming to people that don’t work with fiber optic cable regularly. So here are some common questions.

Do you need singlemode or multimode fiber optic cable?

If you already have a cable and you need more of it, you can usually tell the type of cable by the color of it. Single-mode cable is typically yellow.  Multi-mode cable (either 62.5 micron or 50 micron) is usually orange. And 10GB multi-mode cable is usually aqua.If you don’t know the color, you have to find some sort of documentation that describes the type of cable you need. Below are some terms and the type of cable they are usually associated with.

·OS1, OS2, 9 micron, 9µm, 9/125 = Singlemode

·OM1, 62.5 micron, 62.5µm, 62.5/125 = Multi-mode 62.5

·OM2, 50 micron, 50µ, 50/125 = Multi-mode 50

·OM3, 10GB, 10gig, 50 micron, 50µm, 50/125 = 10GB Multi-mode

As you can see, it can be a bit confusing since both 50 micron and 62.5 micron are multi-mode and are orange. It’s also confusing because 50 micron cable can also be 10GB aqua cable. In cases where it isn’t clear, you may have to find documentation for the hardware you are using to figure out what you really need.The different cables all have strengths and weaknesses.  Single-mode cable is frequently used for very long distance cable runs. It’s not unusual to use a 20KM piece of single-mode cable. But, the hardware to support single-mode cable is traditionally more expensive.

Multi-mode fiber doesn’t work over such long distances, but the hardware for it is traditionally less expensive. Multi-mode 62.5 and multi-mode 50 are commonly used with LED based communications hardware. 10GB multi-mode, which is also 50 micron, is faster than the other types of multi-mode, mainly because its been designed to work with faster, laser based communications hardware.

What is Return Loss?

When light hits the end of a fiber optic cable, a portion of it can bounce back towards the source. This is known as Back Reflection and it can cause a few different problems. Return Loss is the term for how much the end of a cable cuts down on Back Reflection. You want as much Return Loss as possible.

What is Insertion Loss?

When light travels out of the port on your hardware into the fiber optic cable, some of it is lost in the transition. The amount that is lost is referred to as Insertion Loss. You want as little Insertion Loss as possible

Do you need UPC?

Most of our customers are simply looking to minimize Insertion Loss and maximize Return Loss. This means they want as much light as possible to pass through the fiber to its destination and as little light as possible to bounce back to its source. For most applications, UPC will provide this for you. However, in some circumstances, you need more Return Loss than UPC can offer. That is when you use APC. If you have green connectors on your fiber or devices, you may need APC.

Do you need APC?

APC is designed specifically to maximize return loss. APC ends are actually polished to have an ~8° angle on the end of the fiber. An APC end will almost always have a green connector to make it clear that the fiber is APC. The part that is actually polished to an angle is so small that you won’t be able to tell it is angled from looking at it.

If you mix APC and UPC, the result can be tremendous insertion loss (meaning a lot of light will be lost at the point where you connect the APC to the UPC). So, if you have a port on your device that specifies it needs APC, you will need to use a cable with an APC end on it. If you have a cable with a green connector and you want to attach an adapter cable to the end, you will need to make sure an APC end connects to it.

Do you need simplex, duplex, or more?

Simplex cable has a single fiber optic cable and usually one connector on each end. Fiber optic communication equipment typically sends data in one direction on a cable. So, for bi-directional communication, hardware typically uses duplex cable.

Duplex cable has two fiber optic cables and it usually has two connectors on each end. LC and SC connectors can be joined together with a clip that spaces them the correct distance apart to plug both connectors into equipment at the same time. If there is equipment that requires the ends be plugged in closer or farther apart, you can simply remove the clips.

You can also get cable that has many more strands of fiber in it.

What jacket do you need?

Our duplex cable typically comes in a basic zip-cord style where the two fibers are in their own jackets and those two jackets are seamed together. You can also get round jacket cable where multiple cables are run inside a single round jacket, often with reinforcers running through it.

If you are going to be running the cable outdoors or in a conduit where it may be exposed to moisture you will need an Outdoor rated cable.

If the cable is going to be abused in any way, including running along the ground where it might be stepped on or used in a way where it’ll be unwound and wound back up repeatedly, armored cable may be required.

If you want a cable that can be run over by a tank, just mention it, we have something that can handle tanks.

If the cable is in a plenum space, you may need a cable that is plenum rated. Plenum is an air space above multiple rooms. For instance, in office buildings, it’s not unusual for the walls of rooms to only go up as high as the drop ceiling. If you pop your head above the ceiling, you’ll see across many walls and see the ceilings of many rooms. That area is a plenum area where multiple rooms share a common overhead air space. The rules for using plenum vary based on local building codes.

How much do you need?

This is a pretty simple question, but if you need a cable fast, it can be very helpful to know the effect that length has on fiber optic cable.  10GB Multi-mode cable will do up to 10GB/s up to 330M. But, if you need a 20M 50 micron cable that can do 10GB/s then you can often use Multi-mode 50 cable available instead. Here’s a quick chart to show bandwidth vs speed:

Fiber optic patch cord is available in OM1, OM2, OM3, OM4 multimode and OS2 single-mode types. Both ends of the cable are terminated with a high performance hybrid or single type connector comprising of a SC, ST, FC, LC, MTRJ, E2000 connector in simplex and duplex. These are typically not ruggedized, depending on the application, making them suitable for internal use. How to choose right patch cables for your network?

Just follow these 6 steps:

Step 1: Choose the Right Connector Type (LC/SC/ST/FC/MPO/MTP)

On both ends of the fiber optic patch cord are terminated with a fiber optic connector (LC/SC/ST/FC/MPO/MTP). Different connector is used to plug into different device. If ports in the both ends devices are the same, we can use such as LC-LC/SC-SC/MPO-MPO patch cables. If you want to connect different ports type devices, LC-SC/LC-ST/LC-FC patch cables may suit you.

Step 2: Choose Single-mode or Multimode Cable Type?

Single-mode fiber patch cord uses 9/125um glass fiber, Multimode fiber patch cord uses 50/125um or 62.5/125um glass fiber. Single-mode fiber optic patch cord is used in long distance data transmission. multimode fiber optic patch cord is use in short distance transmission. Typical single-mode fiber optic patch cord used yellow fiber cable and multi mode fiber optic patch cord used orange or aqua fiber cable.

Step 3: Choose Simplex or Duplex Cable Type?

Simplex means this fiber patch cable is with one cord, at each end is only one fiber connector, which is used for Bidirectional (BIDI) fiber optic transceivers. Duplex can be regarded as two fiber patch cable put side by side, which is used for common transceivers.

Step 4: Choose the Right Cable Length (1m/5m/10m/20m/30m/50m)

Fiber optic patch cables are made in different lengths, usually from 0.5m to 50m. You should choose an appropriate cable length according to the distance between the devices you want to connect.

Step 5: Choose the Right Connector Polish Type (UPC/APC)

Since the loss of the APC connector is lower than UPC connectors, usually, the optical performance of APC connectors is better than UPC connectors. In the current market, the APC connectors are widely used in applications such as FTTx, passive optical network (PON) and wavelength-division multiplexing (WDM) that are more sensitive to return loss. But APC connector is usually expensive than UPC connector, so you should weigh the pros and cons. With those applications that call for high precision optical fiber signaling, APC should be the first consideration, but less sensitive digital systems will perform equally well using UPC. Usually, connector color of APC patch cable is green, and of UPC patch cable is blue.

Step6: Choose the Right Cable Jacket Type (PVC/LSZH/OFNP/Armored)

Usually, there are three cable jacket types: Polyvinyl Chloride (PVC), Low Smoke Zero Halogen (LSZH) and Optical Fiber Nonconductive Plenum (OFNP). You can see there features in figure below and choose the right one for your network.

Besides the three cables mentioned above, there is another common cable—Armored Cable. The double tubing and steel sleeve construction make these patch cables completely light tight, even when bent. These cables can withstand high crushing pressures, making them suitable for running along floors and other areas where they may be stepped on. The tubing also provides excellent cutting resistance, abrasion resistance, and high tensile strength. Fiber-Mart provides all kinds of fiber optic patch cables to meet demands of various customers!Any questions feel free contact us: product@fiber-mart.com

Everything you need to know about OM1 vs OM2 vs OM3 vs OM4 vs OM5

There are four commonly used OM (multimode) fibers: OM1, OM2, OM3 and OM4. Each type of them has different characteristics. The article will compare these four kinds of fibers from history,the side of core size, bandwidth, data rate, distance, color and optical source in details.

Fiber optic cable can be divided into several types. Usually we see single-mode and multimode fiber types available on the market. Multimode fibers are described by their core and cladding diameters. The diameter of the multi-mode fiber is either 50/125 µm or 62.5/125 µm. At present, there are four commonly used OM (multimode) fibers: OM1, OM2, OM3 and OM4. Each type of them has different characteristics. The article will compare these four kinds of fibers from history,the side of core size, bandwidth, data rate, distance, color and optical source in details.

The picture above shows the development of OM multimode fibers. The Lime Green OM5 fibers are newly released and sure to be the mainstream transmission media in the near future.

specification of OM1, OM2, OM3 and OM4

Core Size

Multimode fiber is provided with the core diameter from 50 µm to 100 µm. Apart from OM1 with a core size of 62.5 µm, other three types are all using the 50 µm. The thick core size makes them able to carry different light waves along numerous paths without modal dispersion limitation. Nevertheless, in the long cable distance, multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission. And this is why all the types of multimode fiber can only be used for short distance.

11111

Bandwidth

Bandwidth is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second. The higher bandwidth is, the faster transmission speed can be. According to overfilled launch (OFL) and effective modal bandwidth (EMB) measurements, OM1 and OM2 fibers can only support OFL, but OM3 and OM4 are able to support both measurements. At the wavelengths of 850/1300 nm under OFL, the respective bandwidth of OM1, OM2, OM3, OM4 is 200/500 MHz*km, 500/500 MHz*km, 1500/500 MHz*km and 3500/500 MHz*km. And at the wavelength of 850 nm under EMB, the bandwidth of OM3 is 2000 MHz*km and OM4 even reaches 4700 MHz*km.

Data Rate

Data rate is a technical term that describes how quickly information can be exchanged between electronic devices. With a higher data rate, the transmission can be more effective. OM1 and OM2 support the Ethernet standards from 100BASE to 10GBASE with a minimum data rate of 100 Mbps and a maximum data rate of 10 Gbps. Compare with OM1 and OM2, OM3 fibers and OM4 fibers are enhanced to support much higher data rates of 40 Gbps and 100Gbps in 40G and 100G Ethernet.

55

Distance

Multimode fiber is typically used for short distance transmission. But the maximum reaches are varied in different multimode fiber types. Also, on account of different data rates, the transmitting distances are different. However, the common feature is that OM1 always supports the shortest distance yet OM4 supports the longest. For instance, based on the same data rate of 10 Gbps, the maximum reach of OM1 is 33 m, OM2 is 82 m, OM3 is 300 m and OM4 is 550 m. Thus, if a medium-sized transmission is required, OM3 and OM4 fibers are the best choices.

Color & Optical Source

The outer jacket can also be a method to distinguish OM1, OM2 from OM3, OM4. The common jacket color of OM1 and OM2 is orange, and OM3, OM4 are in aqua. In addition, OM1 and OM2 are using a light-emitting diodes (LEDs) optical source but OM3 and OM4 adopt the vertical-cavity surface-emitting laser (VCSELs) optical source.

44

color and optical source of OM1, OM2, OM3 and OM4

Application

OM1 fibers and OM2 fibers are widely employed for short-haul networks, local area networks (LANs) and private networks. OM3 is applied to a larger private networks. Different from the previous multimode types, OM4 is more advanced to be used for high-speed networks in data centers, financial centers and corporate campuses.

Conclusion

It is very important to choose the right fiber type for your application. Future-proofing network design is crucial for network planning, but there is often a cost for that speed. With a higher performance, OM3 fibers and OM4 fibers are definitely more expensive than OM1 and OM2 fibers . So plan well and spend wisely.

Introduction of Loopback Cable and How do we Create it?

A loopback cable is also known as loopback plug or loopback adapter, which is a plug used to test physical ports to identify network issue. It provides system test engineers a simple but effective way of testing the transmission capability and receiver sensitivity of network equipment.

In our day to day jobs we find ourselves lugging around more and more hardware; pda, laptop, cell phone, and sometimes even hubs. Why do we carry a hub around when sometimes all we need is a link on our ethernet cards so that all the applications on the system work. Yes, I know you could setup a loopback software adapter. But if you are looking to have the system configured as close to the real setup as possible and you don’t want to carry a hub around, just to get a link light on your NIC. Consider building yourself a loopback cable.

What Is Loopback Cable?

A loopback cable is also known as loopback plug or loopback adapter, which is a plug used to test physical ports to identify network issue. It provides system test engineers a simple but effective way of testing the transmission capability and receiver sensitivity of network equipment. In a word, it is a connection device that is plugged into a port to perform a loopback test. There are loopback plugs for many different ports, including serial ports, Ethernet ports, and WAN connections.

Loopback Cable Type

Fiber Loopback Cable

Fiber optic loopback incorprates two fiber optic connectors which are plugged into the output and input port of the equipment respectively. Therefore, fiber loopback cables can be classified by the connector types, such as LC, SC, FC, MTRJ. These fiber optic loopback plug connectors are compliant to IEC, TIA/EIA, NTT and JIS specifications. Besides, fiber optic loopback cables also can be divided into single mode and multimode fiber loopback. To describe this item clearly, I will take LC fiber optic loopback cable as an example, which is one of the most popular cables (as shown in the following figure). The LC fiber optic loopback cables support the test of transceivers featuring LC interface. They can comply with the RJ-45 style interface with low insertion loss, low back reflection and high precision alignment. LC loopback cables can be 9/125 single mode, 50/125 multimode or 62.5/125 multimode fiber type.

RJ45 Loopback Cable

A Gigabit RJ45 loopback cable is an exceedingly user friendly cable tester. It looks like a simple plug at first glance, but the compact and rugged design makes it highly portable and usable in the tightest corners. All you have to do is to simply plug the Gigabit RJ45 loopback into the jack that you want to test or the one you are suspicious about. If the link LED on your switch is active, it means that the connection is operating perfectly. The RJ45 loopback cable will negate the necessity to carry a bulky network hub around.

How to build the loopback cable simplified?

If you are handy with building ethernet cables, the simple explanation is;

  1. Redirect Pin 1 to Pin 3 and Pin 2 to Pin 6.
  2. Make sure you create tight twists to account for signal interference at such a short length.

4

How to build a loopback cable illustrated?

Step 1. Get a pair of approximately 4 inches in length of cat 5 cable.

Step 2. Leave approximately 1/2 inch at end and start twisting, very tightly.

Note: If your fingers start to hurt, you may want to use a tool to help with the twisting. Notice how tightly wound the cable is. If the twists are not close enough the loopback will not work. Please twist to match picture.

Step 3. After twisting is done, fold cable and line up the ends. Cut if you must to line up cables. Line up the cables so that the cables are in the proper alignment to prepare for insertion into RJ-45 end.

 Step 4: Insert cable into RJ-45 end. (do not crimp yet.) Remember, 1236 pins.

Step 5. Insert plastic tubing over the wire and into the RJ-45 end. Now crimp the end with a crimping tool.

Note: When you first plug in the loopback cable, wait approximately 10 seconds to get a link light. No more carrying around a hub just to get a link light.

Conclusion

All in all, If we know what a is loopback cables and know how to create loopback cables, it will bring many benefits to our work and life.loopback cables play an important role in troubleshooting in laboratories and manufacturing environments. They facilitate the testing of simple networking issues and are available at very low costs. There are many loopback cable manufactures on the market, providing single mode and multimode fiber optic loopback plugs available with FC, LC, MT-RJ, SC connectors. Fiber-Mart is one of the fiber loopback cable providers, all loopback cables are precision terminated and feature extremely low loss characteristics for transparent operation in the test environment.

About Hidden Cable Cabling, You Must Know the Hidden Rules

This article said something about Hidden Cable Cabling, You Must Know the Hidden Rules.

1. People participating in the construction should follow the following:
1.Wear suitable clothes
2.Guarantee the safety of the work area
3. Use safe, qualified tools
4.Formulate construction safety measures in advance

www.fiber-mart.com1

2. Cable laying requirements:
1.Before the fiber patch cable is laid, check whether the specifications, routes, and locations conform to the design rules.
2. The laying of the cable should be straight, do not produce a circle and so on, do not have damage.
3.Before laying out the cable, there must be marks on both ends of the cable, indicating the start and end positions. The label should be used as far as possible.
4.Signal cables, power cables, twisted-pair cables, and other weak cables should be placed as far apart as possible.
The cabling should be redundant. In the secondary exchange room and between the equipment twisted pairs, 3-6 meters must be reserved and the working area should be 0.3-0.6 meters.
5.When laying cables, the distance between the fulcrums of the cables hanging during the traction should not exceed 1.5 meters.

www.fiber-mart.com2

 3. Take the line:

Pull the cable from the cable box

a: Remove the plastic plug

b: Pull a few meters of cable through the outlet hole.

c: Pull out the required length of cable, cut it, slide the cable back into the slot, leaving 5 cm outside.

www.fiber-mart.com3

4. cable processing:

a.Use a diagonal pliers to open the “1” pattern outside the plastic.
b.Hold the fiber patch cable firmly in one hand. Use a long nose pliers to hold one end of the nylon pull string and pull it away from the end of the cable. The length is determined as required.
c.Cut off the useless leather jacket.

www.fiber-mart.com4

5. cable traction:

When pulling multiple pairs of twisted pairs, bundle multiple cables into one bundle and let them terminate.
2.Use an electrician to glue tightly around the cable and wind 5-6 meters outside the end.
3.Pull the rope through the electrical cable with a good cable and knot it.
Note: If you loosen the connection point while pulling the cable, you must retract the cable, and then make a firm connection.

www.fiber-mart.com5

Horizontal wiring considerations:
1) Pipeline routing
Pipeline routing is when the concrete has been buried in the pipeline, the pipeline  traction  cable wire or wire, construction time to understand the pipeline map, make a construction plan.
If there is no embedded pipe, it should be done synchronously with the decoration, so that it is easy to wire and look beautiful and prevent rework.

www.fiber-mart.com6

2)In ceiling wiring:

a.Obtain a construction plan and determine the route.
B. Along the design route, open the ceiling and slowly push the panels apart with both hands.
Put multiple cable boxes side by side with the line up.
d. From the end furthest from the wiring closet, draw the end of the cable along the cable tray over the ceiling of the ceiling corridor.
e.Move the ladder to the next hole in the suspended ceiling until the rope reaches the end of the corridor.
