Overview

For the transmission distance of optical fiber link within 80km, but the actual link loss is relatively large, SPACECOM DWDM dense wave division and dense wave division EDFA can be used

Form of transmission, can effectively solve the problem of line loss.

A simple case

Large line loss, SPACECOM DWDM dense wave division and power amplifier EDFA-BA, line amplifier EDFA-La, front amplifier EDFA-PA combination to solve.

When the line loss is between 18dB and 26dB, the power amplifier EDFA-PA can be used to solve the problem:

When the line loss is between 26dB and 30dB, a power amplifier EDFA-BA and a front amplifier EDFA-PA can be added on both sides to solve the problem:
