How to Terminate Fiber Optic Cables?

Since the late 1970s, various connectors and termination methods have been brought to market. Now in the common case, cables are terminated in two ways: use connectors to make two fibers jointed or to connect the fiber to other network gears; use splices to make a permanent joint between two fibers. And for the former method, you may have little confusions to deal with it. So today this paper will teach you how to terminate by taking an example of fiber optic cable using epoxy.
First and foremost, use a proper fiber stripper to carefully slide the jacket off of the fiber to a bare fiber. When you are doing this, be careful that try to avoid breaking the fragile glass fiber. After that, mix the epoxy resin and hardener together and load it into a syringe (If you use the pre-loaded epoxy syringes that are premixed and kept frozen until use, then you don’t do that). And next you must inject the epoxy from the syringe directly into the connector ferrule.
Once you have well prepared the epoxy for your connector, you can insert the fiber cable gently into the terminus inside the connector wall and make the bare fiber core stick out about a half an inch from the front of the ferrule. In the case that your cable is jacketed, you may need a crimping tool, such as Sunkit Modular Crimping Tool, to secure the connector to the jacket and strength the cables. Usually two crimp tools would be perfect to this operation.
Next, you can just wait the epoxy to cure. During this process, in order to make sure the end of the fiber is not damaged while curing, you should place the connected end in a curing holder. And when this is done, just place the cable and curing holder into a curing oven. But you may worry about “wicking” while curing with a conventional oven. All you have to do to avoid that is to make the end face down, which can ensure the epoxy does not come out of the back side of the connector and compromise the strength member of the cable. Remember: your epoxy curing must in accurate times and temperatures.
After the epoxy cured sufficiently, fiber cleaver tools will be in use to cleave the excess protruding fiber core so that it could make the fiber close as much as possible to the ferrule tip in case of fiber twisting. Once cleaved, you have to dispose of the fiber clipping. There is a point you should think highly of that you must use a regular piece of tape to retain your fiber debris, or they will easily end up in your skin or even in your eyes or respiratory system.
When you finished the fiber cleaved work, you could need fiber polishing tool to remove the excess epoxy from the ferrule tip and buff out any imperfections on the surface of the fiber. A smooth fiber surface can help to reduce the loss of the light. Last, if you have done all the above work, you may move on to the cleaning of the ferrule and fiber tip. After that, the whole termination procedure is done.

Fiber Optic Cables Bring Great Communication Services

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

Fiber optic technology has paved the way for a new type of technology and its effects on home services. Everything from TV, phone, and even internet services have been positively altered due to the advancements brought on by fiber optic technology. With internet services in particular, this new form of connection allows for the internet to go in a direction that it has not always been able to go. Fiber Optic Internet is a step forward toward an unstoppable internet connection.
Optical communication motivation began with the invention of the laser in the early 1960s. Since then, the technology has evolved at the speed of light. Optical technology has advanced so fast that it has become the information conduit of the world. The transmission of data, voice and media is distributed at the speed of light over a mesh of glass fibers that span thousands of kilometers throughout the world. Fiber optic cables have developed to various types, mutimode fiber cable and single mode fiber cable are the basical one.
Multimode fiber allows multiple rays/modes to couple and propagate down the fiber at the same time. Large core fiber is attractive due to the ease in which light can be coupled into the fiber, greatly reducing transmitter design and packaging costs. Multimode fiber is sensitive to dispersion, which tends to limit an optical system’s distance and bandwidth. Multimode fiber can be stepped-refractive-index-profile, or graded-index-profile. While, single-mode fiber has an advantage of higher capacity/bandwidth and is also much less sensitive to the effects of dispersion than multimode fiber. It is also possible to incorporate wavelength division multiplexing techniques to further increase the transmission capacity of a single-mode fiber.
Fiber Optic Internet creates a different kind of online user experience as compared to other types of connections. No longer do users worry about losing connectivity during operations because of the quality of the transmission. Fiber optic technology also allows users to eliminate waiting for pages to load, messages to send, and images to appear. An overall more comfortable surfing experience is provided by fiber optic technology. With the increased popularity of social media sites and live content sites, a fiber optic connection allows users to more completely engage and interact. This type of internet connection is more able to meet the increasing demands of today’s internet-heavy society.
All fiber optic cable manufacturers diverse fiber cables but their item literatures should be cautiously studied so as to assess which variety of fiber cables they specialize in. Want to buy fiber optic cable, recommend you FiberStore, who provdes really high quality cables with reasonable price.

Everything you need to know about fiber optic cables- Including OM5

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

You’ve started a project to upgrade your network but not sure of what fiber cables you need. Should the cables be single-mode or multi-mode? Is there a specific length or speed needed? All of these questions are great to ask as you prepare your network project and think of future upgrades. Here is everything you need to know about fiber cables including the newest fiber type, OM5.
There are primarily two types of fiber optic cabling in the IT space.  Those two types of fiber optic cable are single-mode and multi-mode.  An optical fiber cable is constructed of a core (inner layer), cladding (layer around the core), and jacket (coating around the cladding).  Some layers of protective sheathing are added depending on the application and environment.
Single-mode fiber optic cables have a typical core size of 8.3 to 10 microns (in diameter) and a cladding size of 125 microns.  Single-mode cables are normally used in long distance applications with lasers for the optical transmission devices.  OS1 and OS2 are the standard types of single-mode fiber cables.  Both types of fiber cables are built to perform between 1310 nm and 1550 nm, but the OS2 types of cables have a better transmission performance especially over longer distances.
Multi-mode fiber optic cables have a typical core size of either 50 microns or 62.5 microns.  They have a cladding size of 125 microns.  Shorter cables distances, especially in data centers, are common uses for multi-mode cables.  Multimode cables are typically manufactured to certain specifications and are classified by Optical Mode categories.  These Optical Modes are known as OM1, OM2, OM3, OM4, and OM5.  OM1 fiber optic cables have a 62.5 micron core size.  All the other OM types listed below have 50 micron core sizes.
OM5 is the newest type of multi-mode fiber optic cables, and it is backwards compatible with OM4.  This type of fiber was formerly called Wideband Multi-mode Fiber.  OM5 is constructed to perform outside the normal operating bands of typical multimode cable.  It can support wavelength division multiplexing (WDM) between the wavelengths of 850 nm and 953 nm.  OM5 fiber cabling can transmit at least 4 wavelengths in the 850 nm to 950 nm range.
OM4 fiber optic cables are a fairly new type of fiber cables as well.  This color of fiber cables has been used for the past couple of years in Europe.  The reason for this was mainly to distinguish between aqua OM3 cables and aqua OM4 cables.  The new violet color of cables helps with this quick distinction.

How Do Fiber Optic Cables Bend Light?

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

Fiber optic cables quickly send signals across long distances in the form of light. Each cable is made up of thin strands of glass called “fiber optics,” pieces of glass that send signals using light. Fiber optic cables are useful because they use light, rather than electricity, meaning that other electronic devices in the area will not cause them interference. Many large-scale scientific projects, like hardron particle colliders, use fiber optic cables to send signals quickly.
Light, as you probably know, travels in waves, spreading straight out in a cone from its point of origin. But how do you get light to bend around corners, running through the length of the fiber optic cable?
Bending Light with a Mirror
If you wanted to shine a light down a narrow hall, you could simply aim the light at the end of the hallway. The beam would spread out with distance, so you might need to adjust your focus, but you should have no problem hitting the end of the hallway.
But what if the hallway bends? How can you get the light around the corner? Simple: use a mirror to reflect the light.
Total Internal Reflection
Fiber optic cables uses a similar principle to send light signals. It’s called “total internal reflection.” This means that no matter where you send the light signal in the fiber optic cable, the light will be reflected internally and contained within the tube. This ensures that fiber optic cables will have no problems bending as they send light across long distances.
Signal Loss and Wavelength
Fiber optic glass cannot be perfectly pure, which means that the signal will necessarily degrade over time. The rate of signal decay depends on two factors: the wavelength of the light and the purity of the fiber optic glass.
Wavelength Explained
Let’s talk about what wavelength means. In physics, there are two different ways to talk about light: the light that we see and the light that we can measure mathematically. Light, as I mentioned, is waves, so physics measures light in terms of the length of these waves in nanometers. Our brain interprets these wavelengths as different colors.
Infrared
The wavelengths used for fiber optics are typically much longer than visible light. Typically the wavelengths range between 850 and 1550 nanometers. This invisible spectrum of “long” light is called infrared (the opposite end, the wavelengths too short for us to see, are called ultraviolet).
Attenuation and Scattering
When these infrared waves are transmitted across fiber optic cables, the glass (as I mentioned) slows down or weakens the transmission. This attenuation of the infrared light happens in two ways: absorption and scattering. Absorption occurs because of minute vapor particles trapped inside the fiber optic glass. Scattering, by contrast, happens when the infrared light bounces off atoms or molecules in the glass.
The length of infrared light reduces scattering and absorption, helping the signal stay clear.
Why Not Use Even Longer Light Waves?
You might be wondering: If the length of the waves reduces attenuation, why don’t we use even longer wavelengths for fiber optics? What sets the maximum threshold for wavelengths?
If we used lower frequencies, there would be heat interference. All things have a temperature, which means that everything will give off some degree of heat. Some of this energy given off as heat takes the form of infrared light. If we made the wavelengths any lower, the temperature of surrounding objects would cause interference, resulting in signal loss.

Importance of Reestablishing Fiber Connections Effectively

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

Fiber Optic cables offer a business many benefits for safe, fast installations with higher bandwidth frequencies. Fiber optic cables provide extreme pull tensions up to 600 lbs and a bend radius equal to coax cables.
If loss of fiber does occur it can result in disrupted communications and negative effects to local businesses. Review the steps below in order to repair any tainted connections quickly and effectively.
Making a plan of how to respond to any cable failure is a great idea. Have questions answered ahead of time such as: Do we have the proper equipment if a loss occurs? Who will have proper training and materials to fix the issue? How will we know if the issue occurs? How quickly do we want to be able to resolve any issues?
Important Factors to Restoring a proper connection effectively
1) Documentation- Producing accurate documentation during the installation process and making updates is critical. Start with manufacturer data/tech sheets, review every component and contact for quick restoration.
Example: Having a record of how the fibers were installed as well as photos/drawings to quickly locate where the problem lies.
2) Proper Testing Equipment- To troubleshoot any connection start at the receiver and measure the optical power of the cable. If power levels are showing correctly the transmitter is properly working and the fiber within the cable has not be tainted. However, if the power is bad then there could be an error within the transmitter.
If all fibers are at total failure then the cable has either been broken, split or cut in some way. To determine this use a  laser light beam to show visibly where the cable has been damaged. Once the issue is located remove at least 10 m from either side of the cable break and test the remaining length for damage. Prep the cable and splice the fibers together to restore critical service as a short-term fix and have the system shut down at a later date to permanently fix the damaged cables.
3) Repair- Fixing the damaged cable requires proper tools and trained technicians. Tooling will include splicing and termination. Generally, cut cables can be spliced or reinstalled if there is an excessive cable that was kept from the initial install.

Fiber Optic Cables Are The First Option For Data Transmission

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

Fiber Optical Cable has brought a revolution to the data transmission system. As the earlier Electrical Wire System was difficult to manage and was sometimes also hazardous to life. With the emergence of Fiber Optical Cable, data transmission is no more an irksome job. It is now simplified, providing much more convenient than ever imagined.
Following Are The Reasons For Choosing Optical Cables For Network Cabling:
Safe To Use: Fiber Cable is far better than copper cable from the safety point of view. Copper and Aluminum Wire are good conductors of electricity and carry electric current. But when their outer insulated coating gets damaged, one can experience electric shock that can be dangerous to life. In this regard, Fiber Cables are safer to use because they do not transmit current but rather light waves.
Withstand Rough Conditions: Fiber Cable is capable of resisting tough conditions that co-axial or any other such cable cannot do. The reason is that other cables are usually made up of one or the other metal and are prone to corrosion, while Fiber Cable is covered with protective plastic coating with glass inside and transmits light impulses in spite of electric current, which make it resistant towards corrosion.
Long Distance Data Transmission: There cannot be any comparison in terms of data carrying capacity of Fiber Optical Cable and Copper Cable. Fiber Cable can transmit signals 50 times longer than Copper Cable.
Moreover, signal loss rate of Fiber Optical Wire is also very less, and thus does not need any kind of reminder in transmitting the signals at same pace. Fiber Cable has higher bandwidth that is amount of data communication resources available or consumed – this is the reason how Fiber Cable can transmit data at longer distances.
Duplex OM3 10G 50/125 Multimode Fiber Optic Patch Cable
Easy Installation: Ethernet Cable is long and thin with intact cables inside. It is also light in weight which makes its installation at almost every place easier as compared to other wires.
No Electrical Interference: Fiber Optical Cable neither carries electric current nor need earthing. Therefore, it does not get affected by the electrical interferences. Fiber Cable is immune to moisture and lighting, which makes it ideal to be fitted inside the soil or an area where there is high Electromagnetic Interference (EMI).
Durable and Long Lasting: Fiber Optical Cable is durable and lasts longer than any other cable such as Co-Axial Cable, Copper Cable, etc. It is perfect for network cabling.
Data Security: Extra security can be provided with Fiber Optical Cable as it can be tapped easily and data transmitted through it remains secure, while in case of the Copper Cable there is no surety of data security and any loss of data cannot be obtained back.
There are various types of optical fiber cables available on the market, including 250um Bare Fiber, 900um Tight Buffer Fiber, Large Core Glass Fiber, Simplex Fiber Cable, Duplex Fiber Optic Cable, OM4 OM3 10G Fiber Cable, Indoor Distribution Cable, Indoor & Outdoor Cable, Outdoor Loose Tube Cable, Fiber Breakout Cable, Ribbon Fiber Cable, LSZH Fiber Optic Cable, Armored Fiber Optic Cable, FTTH Fiber Optic Cable, Figure 8 Aerial Cable, Plastic Optical Fiber, PM fiber & Special Fiber, etc. They are used for different applications, one must do a thorough research before buying fiber cables for network cabling.

Common Types Of Fiber Optic Cables And Patch Cables

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

1.FTTH Fiber Optic Cable

FTTH (Fiber To The Home), as its name suggests it is a fiber optic directly to the home. Specifically, FTTH refers to the optical network unit (ONU) mounted on home users or business users, is the optical access network application type of closest to users in optical access series except FTTD(fiber to the desktop).

There are 5 main advantages of FTTH:

First, it is a passive network, from the end to the user, the intermediate can be basically passive;

Second, the bandwidth is relatively wide, long distance fits the massive use of operators;

Third, because it is carried business in the fiber, and there is no problem;

Fourth, because of its relatively wide bandwidth, supported protocol is more flexible;

Fifth, with the development of technology, including point-to-point, 1.25G and FTTH have established relatively perfect function

2. Indoor Fiber Optic Cable

Indoor optical cable is classified according to the using environment, as opposed to outdoor fiber optic cable.

Indoor optical cable is a cable composed of fiber optic (optical transmission medium) after a certain process. Mainly by the optical fiber (glass fiber is as thin as hair),plastic protective tube and plastic sheath. There is no gold, silver, copper and aluminum and other metal, fiber optic cable generally has no recycling value.

Indoor fiber optic cable is a certain amount of fiber optic forming to cable core according to a certain way, outsourcing jacket, and some also coated layer of protection, to achieve a communication line of light signal transmission.

Indoor cable is small tensile strength, poor protective layer, but also more convenient and cheaper. Indoor cable mainly used in building wiring, and connections between network devices.

3. Outdoor Fiber Optic Cable

Outdoor fiber optic cable, used for outdoor environment, the opposite of indoor cable.

Outdoor cable is a type of communication line to achieve light signal transmission, is composed of a certain amount of fiber optic forming to cable core according to a certain way, outsourcing jacket, and some also coated with outer protective layer.

 

Outdoor cable is mainly consists of optical fiber (glass fiber is as thin as hair), plastic protection tube and plastic sheath. There is no gold, silver, copper and aluminum and other metal cable, generally no recycling value.

Outdoor cable is greater tensile strength, thick protective layer, and usually armored(wrapped in metal). Outdoor cables are mainly applied to buildings, and remote networks interconnection.

4.Fiber Optic Patch Cable

Fiber optic patch cable, also known as fiber jumper, used to connect from the device to fiber optic cabling link. Fiber jumper has a thick protective layer, generally used in the connection between the fiber converter and Fiber Termination Box. Commonly used fiber jumpers include: ST, LC, FC and SC.

Main Categories

Single-mode fiber patch cable: General single-mode fiber jumper is colored in yellow, connector and protective sleeve are blue; long transmission distance.

Multi-mode fiber patch cable: General multimode fiber jumper is colored in orange and some in gray, connector and protective sleeve are beige or black and the transmission distance is short.
