Green Telecom specializes in the production of Fiber Optic Cable, Fiber Optic Splice Closure , DOME Fiber Closure and other communication equipment . Different fiber optic applications often require different fiber optic cable. Cable environment is the major factor in the type of cables chosen and it determines the fiber cable construction.

Many types of environments exist for fiber cable's applications.

1. Fiber optic cables linking devices such as computers, telephone systems, distribution panels and fiber splice organizers. Generally speaking, these fiber cables are the least expensive and cable construction is very simple, because the devices can protect the fiber cables from outside forces and mechanical dangers.

2. Fiber cables installed across a room, under a floor, between walls or above suspended ceilings. These areas are usually plenum areas which means they are used for air exchange by HVAC systems. The fiber cables used here must meet fire and smoke codes set by National Fire Protection Association and National Electrical Code.

3. Intrabuilding cables are often constructed as breakout cables. This design eliminates the need for patch panels in terminal closets. The fiber cables can be divided into individual fibers for distribution.

4. Direct-burial cables. These cables are laid into deep trenches or plowed into the ground. Extra protection again moisture and temperatures are demanded for this kind of environment. The outer jacket of these direct-burial cables provides these protections.

5. Aerial installation fiber cables can be aerial installed on poles or lashed onto messenger wires between poles. These cables are usually all-dielectric which means they contain no metal components inside. This makes the cable lightning immune. The cable must be strong enough to prevent sagging that would put excess stress on the fibers.

For your fiber optic cables to work effectively you need to install them properly. To guide you, here are tips on how to install the units:

Use the right components

The components that you use depend on the application. While this is the case, there are some components that are universal regardless of the application. These components include:

Patch panel: They make it easy for you to manage the patch cables and link the cabling distribution areas. When buying the unit you should go for one that allows you to use different cable connectors in the same patch panel. Experts also recommend that you go for units with colored jacks or bezels. This is to make it easy for you to identify the different ports.

Cable manager: The cable manager protects the units from damage. It also provides a routing for the patch cables. The cable managers are of two main types: horizontal and vertical. When buying the units always ensure that no parts obstruct the effective transfer of data.

Cable ties: They hold a group of cables together. They also fasten the units to other components. As rule of thumb, ensure that the ties that you buy are of high quality.

Have a plan

You can't do a good job if you don't have a plan on how to install the optic cables. To have an easy time you should have a plan on how you will go about it. You should know where you will begin the installation and where you will end. To easily identify the units you should come up with a coloring code. You can use the code on patch panels, fiber cables, color sleeves and connectors.

Experts recommend that you use thin and high-density cables when possible. This to make it possible for the cables to run in tight spaces without getting damaged. If you are installing the units in areas that already had cables, you should remove the abandoned units that might restrict air flow. Abandoned cables are also more likely to cause a fire. You should avoid routing cables through holes and pipes as it might limit running the units in future.

The contractor that you hire has a great impact on the performance of the cables. For peace of mind, work with a certified and experienced professionals. After installing the cables it's always recommended that you keep records detailing where the different components were installed. This makes it easy for you to troubleshoot the problems.


The Fiber Optic Splice Closure connector design listed above is very basic. There are industries that require special connector designs though. One design is identified as the subminiature Type A or SMA. This is one that highlights the ostensible screw-on mechanism. This kind of connector has different designs, for instance, some with straight screw connectors while others with smaller connection mechanisms found on either ends of the connector.

An additional kind of connector for Fiber Optic Splice Closures is recognized as the straight-tip or ST connector. This one depends on a bayonet mount lock, a flexible link that can either be separated then refastened with much ease. Of course, the square connector or SC is also highly chosen especially because it prevents crossing of fibers during installation. This one is easily discernible to the user as it has a square tip.

Clean the Fiber Optic Splice Closures

When cleaning the various parts you should take care that you don't allow the cleaning alcohol to evaporate off the ferrule. This is to prevent having a residual material on the fiber core and cladding. If you let the alcohol evaporate you will have a difficult time removing the cladding. In most cases you will be forced to use the wet cleaning method which as mentioned above, can easily result in damage of the different parts.

When cleaning the different parts take caution that you don't touch the parts. In addition to leaving marks on the parts thus making it difficult for you to clean the box, you also risk collecting harmful glasses that might injure you.

Fiber optic box are a type of box used in fiber optic networking, which uses light rather than electrical signals to transmit data. They are carefully designed to align and protect two segments of optic fiber, and were among the first boxs widely used in optic networking. fiber-optic boxs use a bayonet-style twist and lock mechanism and can be used with both single and multimode fiber. The boxs are used in data centers, short to medium range network links, and military and security applications.

Using light as a transmission medium allows fiber optic cables to carry much more data than their electrical copper-based counterparts, but it also presents some unique problems. Fiber optic boxs must be designed with precision as a top priority, because even a small amount of dust or slight misalignment between fiber segments can greatly reduce performance and reliability.

Fiber optic boxs can be divided into these types:FC type fiber optic box,SC type fiber optic box, MT-RJ box, LC box and so on.

The main purpose of fiber optic boxs is to achieve fiber connections. Now widely used in optic fiber communication system in the optic fiber box, its many types, different structure. However, the basic structure of various types of fiber optic boxs is consistent, that is, the vast majority of fiber optic boxs generally use high-precision components (by two pins and a coupling tube composed of three parts) Alignment of the fiber.

This method is to penetrate and fixed the fiber in the pin, and the pin surface after polishing, in the coupling tube to achieve alignment. The outer part of the pin is made of metal or nonmetal material. The butt end of the pin must be ground and the other end usually uses a bend limiting member to support the fiber or fiber optic cable to release the stress. Coupling pipe is generally made of ceramic, or bronze and other materials made of two semi-synthetic, fastened cylindrical components made of multi-metal or plastic with a flange, in order to facilitate the installation of the box fixed. In order to precisely align the optic fiber, the pin and the coupling pipe processing accuracy requirements are high.

The main advantage of the light box is simple operation, fiber optic cable stripping only once, the construction speed. It does not require the operating environment, the tools needed is easy to carry.

Plenty of connectors are involved with fiber distribution box. The connectors have different roles and using the wrong one at the wrong place will result in the network not working effectively. To ensure that you install the right connector you should take your time to familiarize yourself with them. The most common that you need to know about are "stick-and-click," "stick-and-twist," and "lucent connector." Every connector should be used at its right place. If you have never installed the cable before ask a professional to help you with the installation. Green Tel is a company specializing in the production of communication components, mainly producing Fiber Optic Splice Closure, Fiber Closure, Inline Closure, DOME Fiber Closure, etc. The following is the relevant knowledge for everyone.

Never mix single mode and multimode cables

While the two cables might look similar, thus be tempted to mix them up, they are very different and you should never use them on the same line. Before you go ahead with the installation you should know that the two are incompatible. The two types of cables have many differences.

Multimode cables have a larger core size that makes it possible for you to uses less-powerful, less-expensive light sources. Its major flaw is that it lends itself to modal dispersion where light tends to bounce around inside the core. This limits the cable's useful range to about 2 kilometers.

On the contrary, single mode fiber combines powerful lasers and cabling with a narrow core size of 9 microns in order to keep the light focused. The cable has a range of up to 130 km. Its major flaw is that it's expensive thus you should be ready to part with a substantial amount of money.

Protect the receiver by attenuation

If the designers used a single mode fiber over a short distance, it can result to oversaturation of the receiver at the end of the connection. To protect the receiver you should undertake attenuation. This is where you deliberately reduce the signal strength without impacting the integrity of the line. There are many attenuators that you can go for. The most common are the O-rings that come in different dB values. A professional will guide you on selecting the right ring when you are working.

Fiber is a shorthand of optical fiber, is a glass or plastic made of fiber, can be used as a light transmission tool. Is now commonly used long-distance networking materials. If the long-distance network failure, if you can not quickly determine whether the fiber failure, for the emergence of network failure, will greatly delay the troubleshooting time.GreenTel not only produces Fiber Optic Splice Closure, Fiber Closure, but also brings you knowledge about this.

In general, common fiber failure equipment failure, such as fiber optic box. Fiber optic equipment is mainly due to signal output distortion caused by the transmission process of signal distortion, making a large number of signal loss. Often, the associated output characteristics are affected by temperature and related factors. Whenever the bias current and light intensity changes to a certain extent, the actual electrical output curve of the corresponding working range will change, resulting in the signal up and down the process of moving, the signal is caused by interference loss.

The main faults of fiber optic box that can be measured at present can include fiber failure and fiber optic cable fault, coupler link failure. Specifically, it is also possible to refine the pigtail failure to the actual corresponding radius of the pigtail bending, the pigtail break, and the dust at the flange of the flange. Fiber optic cable fault, including the total cable attenuation is too large and line disruption.
