Fiber Cable Attenuation Coefficient

Fiber Cable Attenuation Coefficient

1- Attenuation is reduction in power of the signal as it is transmitted.

2- When designing a fiber optic system, you need to take into consideration “The maximum channel attenuation”

3- Example : Multimode Fiber attenuation Coefficient is 3.5dB/km and Connector attenuation=0.75dB & Splice attenuation=0.3dB

4- Now: Cable attenuation = cable attenuation Coefficient x length of the cable Total Channel Attenuation =cable attenuation + (# of connectors x 0.75dB) + (# of splices x 0.3dB) .

*Splicing is the joining two fiber optic cables together
