What are the factors that affect the communication cable information?
This will cause the attenuation at the receiver due to the light intensity signal is too weak and cannot receive the signal (the light receiving sensitivity to this problem); optical fiber relay equipment requires a lot of, but because the fiber link is too long, which has second factors: cable construction and maintenance problems. Because of the long distance, high bandwidth and high frequency transmission of optical fiber itself, the distance of optical fiber transmission is widened. At the same time, the wiring and the maintenance of computer room construction are more difficult.
The process of optical signal transmission in a quartz optical fiber, the optical energy attenuation produced light diffusion, resulting in attenuation of signal intensity transition when the remote transmission, resulting in signal distortion. The general signal transmission in the optical attenuation according to the industry standard is 0.3db/km, there is no upper limit value of the argument, if the fiber transition aging, may also cause attenuation of ten dB in 1km is also possible.
There are many factors that affect the optical fiber communication system, and the two most important ones can be summed up as follows: 1. Attenuation of signal transmitted in optical fiber.
