It becomes more and more popular and obvious that fiber optics are used to transmit communication signal. Fiber optic box simply use light pulses to transmit information down lines of fiber. A transmitter, which is at one end of the system, is the place of origin for information coming onto the optical fiber lines. After the transmitter accepts coded electronic pulse information from copper wire, it translates the information into equivalently coded light pulses.
Single-mode is a single stand of glass fiber, usually consisting of 2, with a diameter of 8.3 to 10 microns and has only one mode of transmission. Singlemode, having a relatively smaller diameter than multimode, carries higher bandwidth than multimode, but requires a light source with a narrow spectral width. Although singlemode fiber costs more than multimode, it gives you a higher transmission rate and up to 50 times more distance. The small core virtually eliminates any distortions that could result from overlapping pulses, providing the least signal interruption and the highest transmission speeds of any fiber optic type.
Multi-mode optical has a slightly larger diameter, ranging from 50 to 100 microns. The most common size is of multi-mode fiber optic cable is 62.5 microns. Light waves travel the cables core in order to disperse them into multiple paths, or modes. Unlike singlemode fiber optic products, multimode can become distorted at the receiving end, resulting in an unclear and incomplete data transmission during long cable runs.
Improper cleaning of the connectors would result in the failure of the fiber optic cables to work as efficiently as they should. You should check the connectors using the fiberscope of your choice if you want to start the cleaning process. If you find contaminants, clean the cables using the dry cleaning method. You should inspect the connector again and if still dirty, retry cleaning it using the dry cleaning method. You should inspect it again and if still dirty, try cleaning it using the wet cleaning method. Experts advise against cleaning your optic cable using the wet cleaning method as it usually results to damage to your cable. Only use the wet method after the dry method has failed.
To prevent the connectors from getting dirty you need to protect them from dirt. During the cleaning process, you should never allow the connectors to get into contact with the cleaning surfaces. The connectors usually have plugs and dust caps that protect them from dirt. You should keep these units in place when the connectors aren't in use. In addition to doing this preventing dirt from getting into contact with the cables, it also protects the cables from damage.
To begin with, it is important to know the types in which the fiber optic cable is available. While single-mode cables are useful for long distance installations, the multi-mode versions are apt for short distance applications. It is suggested to obtain the variety which will be compliant with the equipments it will be connecting.
You should inspect whether the cable is damaged or not when you want to buy it. It is an important step considering the high cost of installing fiber optics. Visual fault locator based on red laser light are the tools that can be used for this purpose. There are two essential installation guidelines that must be followed:
The pulling tension for these cables should not exceed the recommended value during installation as well as afterwards.
The bend radius of the fiber optic cable should not exceed the recommended value.
High pulling tension or exceedingly bent radius can permanently damage these cables. A number of tools can be used to ensure correct installation and strength member is one of them. The tool helps in attaining the right grip on the cable so that its effective strength is utilized to the fullest. In order to protect the pre-terminated ends of the cable, another important tool called pulling eye must be used. A great deal of care must be taken to avoid scratching and twisting of the cables. Choosing good fiber optic connectors can increase the worth of the installation.
The most attractive benefits of fiber optic cable is that it supports high bandwidth data transmission. The bandwidth value is extremely higher than that supported by other types of cables. The second advantage is that the bandwidth capacity of these cables can be increased further using different multiplexing techniques. Reduction in electromagnetic interference is another noteworthy advantage that fiber optics offers over other cables.
