11 Common Networking Cable Mistakes

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

Network cabling is one of those things that seems easy on paper but ends up being hard once you apply it in the real world. Most people tend to ignore it but do not realize how much it will cost them in the long run. You could find yourself paying extra costs that were unnecessary in the first place, wasting time on running maintenance tests that never needed to be performed if the job was done right, poor network performance, and much more.

The most surprising thing about networking cable mistakes is that there aren’t thousands of little mistakes that are being made. Many IT professionals agree only a few fundamental mistakes are responsible for the majority of the problems.
Here is a short list of the 11 most common networking cable mistakes that are seen in the IT industry:
1) No cable management. This is where it all starts. Forget testing and other things – you can’t expect solid network performance if you are not properly managing your cables. This means that you will have to do the necessary work of properly labeling your cables and organizing them in a way that they can be easily accessed. Whether you use a rack or some other means, it is important to get this crucial mistake out of the way. It will be far easier to manage the cables, and maintenance will take up less of your valuable time.
2) Failing to plan. Before you even begin to take your cables and start connecting them to every port in sight, you need to know how everything is going to be laid out. Planning out your cable organization in advance is the first step to properly setting up your network.

3) Ignoring the rules. The best cable setup in the world is meaningless if you are breaking the rules! There are certain laws, standards, and codes that you have to abide by at the local, state, and federal level. Read up on the standards that pertain to you and your company. It’s one thing to have a safety hazard because you ignored the rules and another thing to pay hefty fines!
4) Failing to control atmospheric temperature. The environment in which you set up your cables makes a huge difference. If the cables heat up too much, it could lead to the failure of the entire network. Likewise, moisture can also lead to network failure and compromise the safety of nearby workers. You need a system in place to keep all of your cables cool and dry. Cooling systems, air conditioning – whatever it takes to get the job done: Do it.
5) Ignoring distance limits. In general, 100 meters is the limit for the length of a cable. Keep in mind that this distance also includes path leads. Each cabling has its own limits, however, so you need to mindful of the cabling that is being used for your network.
6) Running cables near interference-causing devices. Believe it or not, there are many ways for interference to mess up your cabling setup. There are several types of interference (magnetic, electrical, etc.) that can be caused by seemingly harmless things like motors and fluorescent lighting. The pathway you set up for your cables should be free of these types of hazards.
7) No space for cable removal. The IT environment is dynamic in nature, and changes are going to be happening all the time. Adapting rapidly to change means that you should be able to easily remove cables at any time. If not, you are paving the way for operational hazards. When in doubt, always leave a little more space than you think is necessary.
8) Using separate cabling for data and voice. The traditional way of designing a cable network was to use separate set-ups for data and voice. Due to the different needs of the end user, this is no longer a viable option. Your best bet is to use twisted pair cabling.
9) Running cable parallel to electrical cables. This is a common mistake that usually leads to interference in data transmission from one point to the other. This can be remedied by crossing them in perpendicular instead of parallel.
10) Failing to test your network before activating it. Once everything has been set up, and you are happy with your layout, don’t forget to test your network before activating it. This will help you catch any errors you may have missed and address problems regarding data transmission and safety. Make sure to use the appropriate tools.

11) Failing to ask for help. Sometimes, when all else fails, and you don’t know what to do, you need a second pair of eyes to look at what you have done. Call a licensed, experienced professional to help you set up your networking cable in a way that is safe and helps to transmit data efficiently.
Those are the 11 most common mistakes that you are going to see with networking cable. As long as you are aware of them and pay extra attention during the setup, you should be good to go on the first try! If not, look back at each mistake individually and check to make sure that you did not miss anything.

Uses for Ethernet Cable

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

Ethernet cables are standard wires that connect computers to a network. These cables are specifically designed to facilitate easy communication between disparate electronic equipment. These electronic devices can either be fax machines, printers, scanners, or personal computers.
An Ethernet cable facilitates communication between the internet servers and your personal computer. The cable provides stable internet connection. This means that you can work all day and download and upload your files without stress. Here are a few things you need to know about Ethernet cables:
How to connect Ethernet cables
An Ethernet cord can connect two devices using the Ethernet ports on each. The cable is locked into place by a modular plug. Connecting your device using these cables requires patience because modular plugs tend to break easily. The first thing that you need to do is to hold the cable firmly and then turn it so that the small plastic plug faces up. Insert the cord into your computer’s Ethernet port. A computer has several ports, but an Ethernet port is usually bigger than the other ports. Firmly push the cable into the port until the plug locks into the place. You need to be careful when pushing the cable to the port to make sure that you don’t break the modular plug.
After inserting your plug, you need to check whether the internet is working. If it is not working, you should check whether the cable was inserted well in your computer and in the internet port. This connection process will only take you less than 5 minutes and you are good to go. You can use the Internet to download and transfer large files without any interruptions.
Benefits
Installation simplicity
These cables are easy to install because they come in different sizes. So, you can choose the size that fits your needs. For example, if you buy a hub or a router from one of your local computer shops, you can easily insert the cables into each port on the hardware devices. Computers come pre-built with Ethernet network adapters. This means that you can easily insert cables into the computer even if you don’t have knowledge in network administration.
Speed
Contrary to what most people believe, an Ethernet network is fast. This means that you can use cables to connect several computers in your home and enjoy surfing at a reasonable speed. This cable network connection is fast enough to transfer large files within a short time. This speed is also reliable because cables are not subject to breakdowns such as the case with modems and other wireless devices.
Availability
Ethernet cables are readily available. The cables are also cheaper compared to other types of cables such as coax and fiber. You can easily find a replacement in our selection if you accidentally break your cable. FireFold is here to help if you have any questions!

How to Create a Cat 6 Patch Cable

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

Cat 6 cable (listed in the standard as Category 6) is a standardized cable for 1000GBASE-T (Gigabit Ethernet) that is backward compatible with Category 5/5E and Category 3. It is also suitable for 10GBASE-T (10-Gigabit Ethernet), 10BASE-T, and 100 BASE-TX (Fast Ethernet). New installations often specify Cat 6 cable. It is important for professional installers to understand the requirements of the newer standard and know how to create a standard cat 6 patch cable.
Differences With Cat 5 Cable
Whereas Cat5E cable is only characterized up to 350 MHz, Cat 6 allows up to 550 MHz operation. The greatest performance improvement for Category 6 cable is its increased immunity to alien crosstalk. This type of crosstalk is coupling between nearby connections. In some cases, users can hear other people’s conversations on their line, thus the term crosstalk. The biggest foil to crosstalk is that the 8 cable wires are matched in sets of 4 twisted pairs. Each pair is fed differentially, and common-mode signals (signals which are the same on both wires, such as crosstalk coupling) are rejected. A second technique for reducing crosstalk is to use digital signals, which are inherently resistant.
Physical Characteristics
It is easy to differentiate Category 6 cable by the printing on the side of the sheath. Connectors use either TIA standard T568A or T568B pin assignments. Some technicians get away with alternate configurations. This works as long as both ends of the cable are connected the same way. However, it is not a recommended practice in case another technician comes in to repair one end of the cable later.
Although Cat 6 connectors have the same 8P8C look as Cat 5E and other earlier versions, it is important to use cat 6 rated jacks, connectors, and cables, or the improved Category 6 performance will be degraded.
Installation Caveats
In order to meet Cat 6 specs, installation is everything. Make sure not to kink the cable. This can happen if the bend radius is less than four times the cable diameter. A common installation mistake is to strip the insulation back more than 0.5 in (12.7 mm). Another common problem is allowing the twisted pairs to unravel past the skin point, creating a crosstalk vulnerability point at the connector.
High EMI (electromagnetic interference) environments require special handling. This type of environment may occur when cabling is within a few feet of a power plant, a high power electric motor, high power switches, or other heavy EMI generators. Cable shielding preserves the Category 6 specs and is enhanced by connecting to a drain wire. This wire runs through the actual cable alongside the groups of twisted pairs.
According to Cat 6 directives, the cable shielding is connected to true ground at each cable end through jacks. Unfortunately, this violates the rule of only grounding one side of a shield in order to avoid creating a ground loop. Installers must be careful to place each cable to avoid having a voltage differential from one end of the cable to the other. If this happens, extraneous currents may be generated in the cable, increasing system noise.
How to Make a Patch Cable
Start by assembling the proper tools:
• Category 6 cutter/stripper
• Plugs – these are different for stranded or solid connectors. They are nearly impossible to differentiate visually, so be sure to keep them separate after you make the purchase.
• Crimper
• Boots (optional)
Cat6 Crimp ToolNow complete the following steps:
• Cut the cable to length and strip to 0.5”. Use the boots facing outwards, if desired.
• Carefully untwist the cable pairs – do not go further than the strip.
• Bend the center spine away from the conductor wires and cut at the strip.
• Bring the wires together and cut at a sharp angle.
• Bring the wires together and insert them into the loadbar. Use a 568B wiring diagram. (For a crossover cable, follow the 568A wiring diagram at one end only.)
• Check the wire order one more time, and then make a perfectly straight cut 0.25” past the loadbar.
• Place the connector onto the loadbar assembly. Make sure the copper connectors are up and the locking clip is facing down.
• Make the crimp, squeezing all the way down.
• Repeat the procedure at the other end.
Test the Assembly
Be sure to perform a continuity check religiously with each cable assembly. Consider using a high-quality four-pair tester. If the cable fails, try giving another crimp at each end. If necessary, check the wires by color for the proper positioning. Make sure each wire extends to the connector end and that the pins are pushed down fully. If it still does not work, clip off one connector and try again. If there is still a problem, repeat the examination, focusing in on the end with the original connector. Finally, high-performance 10GBASE-T will need to be tested in situ for alien crosstalk.

How to Keep Fiber Optic Cables in Premium Condition

by Fiber-MART.COM

In any discussion about telephone systems, cable TV, or the internet, you are likely to hear the term “fiber optic cables” thrown in at least a time or two. The reason that fiber optic cables are such a common topic is the sheer number of purposes they serve. These services range from enabling telephone, cable, and internet systems to function. As if that doesn’t cover enough ground, medical imaging, mechanical engineering inspection, and sewer line inspection are some of the many applications that also rely heavily on fiber optic cables.
What are fiber optic cables?
Fiber optic cables are long strands of optically pure glass with about the diameter of a human hair. These strands are arranged in bundles and used to transmit light signals that are capable of carrying digital information over long distances. Given their obvious value, it is particularly important for fiber optic cables to be maintained and kept in the best condition possible.
Fiber Optic Cable Care and Use
Fiber optic cables are durable, but if mishandled or not cared for properly, they will become worn and damaged over time and the quality of their performance will suffer. Sometimes, it’s just as important to know what you shouldn’t do as it is to know what you should do. With that in mind, here are a few of the main dos and don’ts when it comes to handling and maintaining fiber optic cables.
When removing the connector, do not pull or twist the cable. Pulling on the cable may cause the optical fiber inside the cable to break, or remove the cable sheath from the optical connector.
Be careful when bending, folding, or pinching the optical fiber cable. Much like pulling the cable, excessive bending, folding, or pinching can break the fiber optic inside the cable. An optical fiber cable should have a bend radius of 30 mm or more.
Avoid hitting the end of an optical connector against any hard surface. Hard surfaces are not by any means limited to brick and concrete. Whacking the end of a connector on your desk or the floor can damage the end of the connector, degrade the connection, or lose the connection altogether.
Do not hang anything using a cable. This may sound obvious, but it can’t be stressed enough that hanging something by a cable can severely damage the inside of the cable.
Do not touch the end of a broken fiber optic cable. If a cable is broken, touching the end of it will do no good and may cause an injury by piercing the skin.
Keep optical connectors assembled. Disassembling the connectors may cause a part to break or lead to diminishing performance.
How to Store Fiber Optic Cables
Ideally, fiber optic cables should be stored inside, protected from the elements. The reel tag that comes with the cable should be kept so the cable’s origin can be traced in the future, if necessary. Fiber optic cable reels should be stored standing by or supported on both flanges. Sitting it one flange surface will cause strands of cable to gravitate toward one end of the reel. When the cable gathers at one end of the reel, the odds of it being damaged during the unwinding process increase exponentially. If you band your rolls of cable to pallets, the band you use should be placed through the hole in the middle of the reel. The flanges, not the cable package, should come in contact with the pallet. As we discussed, contact with any hard surface can be damaging to the cables.
Respooling Requirements for Fiber Optic Cables
There are a few simple rules when it comes to respooling cable. When choosing a reel size, ensure that it does not exceed the minimum bend radius of the cable. Also, when respooling the cable, make sure that it is evenly distributed evenly throughout the reel. Respool from and to the top of the reel, ensuring that the cable is snug on the respooler drum and that the cable is not being twisted as it’s being reeling up. Once you’re done respooling, allow a minimum of a 1 to 2 inches between the flange edges and the last cable wrap.
Conclusion
Fiber optic cables play a major role in our everyday lives, so it’s crucial that they’re kept in premium condition. By following careful handling, proper storage, and meticulous respooling practices, this is easier than it might seem.

8000 meters deep submarine actually there are optical cables? Is the person who spreads the cable is Iron Man?

If you compare the earth to a computer motherboard. From the phone poles with cables to the warning signs that lay the optical fibers, the world we live in is surrounded by countless lines. In fact, the Internet infrastructure that we can see with our naked eyes is only the tip of the iceberg, and there are countless cables laid in the depths of the dark ocean.You must be more interested in what you would like to eat than you would like to eat at dinner.

1.On the surface of the sea, the ship releases the cable.

图片12.Under the sea, cable ploughs fix the cable to the bottom of the sea. There is also a repeater every 40km to 60km.

图片23.Guaranteed signal.How many optical cables do you need to bring?

图片3

Did you see the turntable on the boat?  It can be said to be super long

图片4The process looks simple, Someone has to ask, is the pressure on the bottom of a few kilometers so large that the fiber is not easily damaged?

Responsibly tell you that submarine cables are more fragile than underground cables, and that different depths of maintenance are different:

1.The general cable fault location receives and sends a complete set of signals first, because the damage of the optical cable is usually the internal fiber breakage, the breakage location will reflect the signal, and the recovered reflection signal is compared with the shape and time of the signal calculated by the mathematical algorithm. Locate the specific location of the fiber breakage.

2.The cable repair ship went to the accident site to repair it. If the water depth is within two kilometers, an underwater robot is generally used to guide to the fault location through an artificial signal, and the damaged optical cable is cut off, and the remaining two ends are pulled back to the repair ship for repair.

3.If the water depth exceeds 2,000 meters, due to pressure problems, deep water grabs will be used, and the image is a hook. If it is a sandy seabed, the optical cable will be directly returned to the sea surface. If it is a rocky seabed, the grab must be along a certain length of the optical cable, so that the position of the optical cable can be adjusted more easily to prevent it from being pinched by rocks.图片5

4.If the water depth is too deep, a single grab cannot pull the entire cable directly back to the surface. At this point, the fiber optic cable needs to be cut off, and now a head A1 is brought back to be fixed with a buoy, and then the other head A2 is pulled with another grab.

5.Fiber optic cable repair is mainly the work of fiber-optic welding. A2 is welded to the newly added spare cable B. Then the repair boat is close to the buoy, and the A1 is rejoined to the remaining part of B. The repaired cable is longer than the original one. The new cable is U-shaped on the sea floor. After the welding is completed, wait until the communication test is successful before returning the cable.

Therefore, the cost of submarine cable is quite high. The cost of a transoceanic fiber cable is several hundred million US dollars. Coupled with the monopoly of real estate giants, the monopoly access prices of domestic operators, the terrible reasons for the high cost of broadband in Hong Kong have also been explained.

Waterproof Fiber Cables

Waterproof fiber optic patch cables are designed to fit for outdoor connection applications. The strong PU jacket and singlemode APC armored structure of cable provide 1Gigabit data transfer speeds in high bandwidth application.

With the development of modern communication industry, optical fiber has become an increasingly important communication line medium because of its advantages such as wide frequency band, low loss, long transmission distance and anti-electromagnetic interference. In metropolitan area networks and campus networks, the application of outdoor optical cables is becoming more and more common. For outdoor optical cables, in addition to bandwidth, loss, and other transmission performance, another very important technical indicator is the optical cable’s water blocking performance.

Waterproof fiber optic patch cables are designed to fit for outdoor connection applications. The strong PU jacket and singlemode APC armored structure of cable provide 1Gigabit data transfer speeds in high bandwidth application, up to 5 times faster than standard 9/125um fiber patch cable. What’s more, it’s IP67MPO cable connectors have an extremely rugged, protective rubber coating with integral anti-kink strain-relief boot and a rubber-coated, metal, latching cap, attached by a steel lanyard. When mated or capped, the connection is environmentally sealed up to IP65. They can resist high temperature and suit to use in harsh environment, and ideal for use in a variety of applications, including Fiber to the Antenna (FTTA) and Fiber to the Home(FTTH).

Like choosing any other fiber optic patch cables, the connector type, fiber count, fiber type (single-mode or multimode), polish type, cable length and cable jacket are factors that should be considered as well. When buying waterproof fiber optic patch cords, the IP (International Protection or Ingress Protection) rating is an important parameter. Knowing the IP code can help you find your wanted waterproof cable.

 

IP rating system is a classification showing the degrees of protection from solid objects and liquids. IP rating codes do not include hyphens or spaces, and consist of the letters IP followed by one or two figures. The first number refers to the degree of protection against the entry of foreign solid objects, such as dust. These protection levels range from 0 to 6. The second number of the IP code refers to the degrees of protection against moisture/liquids, which are raging from 0 to 8. The first and second number of the IP code can be replaced by the letter “6″or7”.Norally called IP67.

There are two types of IP67MPO weatherproof connector: IP67MPO plug (with locating pins) and IP67MPO Socket (without locating pins), the plug of one cable and the socket of the other cable can be connected to extend the cable length. See blow:
