EDFA Rack-Mount / 1U Chassis-Based

EDFA Rack-Mount / 1U Chassis-Based

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 Device Settings Details
Setting 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
Setting 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
Setting 3 Setting of eye protection mode
When installing, debugging or dealing with faults, the amplifier eye protection mode can be opened through the network management to reduce the output power of EDFA and avoid harming maintenance personnel
