Description
Overview of EDFA
The main function of EDFA(Erbium Doped Fiber Amplifier) optical amplification equipment is to compensate the power of signal light in the transmission link, and can simultaneously amplify the optical signals of up to 48 channels (channel interval is 100GHz) or 96 channels (channel interval is 50GHz) in C- band. It has the characteristics of flat gain, adjustable gain and small noise index, it is an indispensable part of DWDM system and future high-speed system, all-optical network long-distance transmission.
EDFA amplifier from the application position can be divided into: power amplifier, line amplifier, preamplifier;
BA power amplifier: It has the characteristics of high input power, high gain and high output. It is mainly used at the transmitting end of DWDM system to improve the optical power of DWDM system;
LA line amplifier: It has the characteristics of low input power, high gain, high output, etc. It is mainly used in the middle of two network nodes in DWDM system to improve the transmission power of DWDM system;
PA preamplifier: It has the characteristics of low input power, high gain and low output. It is mainly used for DWDM system terminal to improve the received optical power of DWDM system.

| EDFA Device Settings 1. Input and output power alarm threshold setting The amplifier input and output power alarm threshold can be set through the network management, when the input power is lower than the threshold, EDFA alarm, at this time EDFA pump is turned off, EDFA does not work, EDFA output below the threshold will prompt alarm; 2. Working mode setting The amplifier working mode can be set through the network management: AGC constant gain mode, APC constant output mode and ACC constant current mode. The gain can be set in AGC mode with the best setting range of ± 1db. The output power can be set in APC mode with the best setting range of ±1dBm; |
