1550 edfa LTEDFA-1550 1-4 way output 1550nm Erbium-Doped EDFA
Overview
LTEDFA - 1550 amplifier is equipped with the international famous brand new original stabilized pump sources with low noise figure, high and stable saturation output optical power. It can be used for cable TV images, digital TV signal, telephone voice signal, and long distance, large transmission data signal.
Built-in microprocessor built-in the rack can monitor pump working status and input/output optical power on a real - time basis.When optical fiber amplifier work abnormally,it will output the corresponding alarminformation.when a serious warning appear , it will turn off the pimp laser automatically to protect the amplifier.
Features:
u This machine adopts imported optical module, pump laser and erbium doped amplifier
u The perfect and stable circuit of optic power output and controlling circuit of thermoelectric refrigeration device of laser module assure the user the best quality and stable working
u The internal micro-processor software has many functions such as laser monitoring, digital display and trouble alarm and on-line management. Once the working parameter of the laser is out of the fixed range, there will be a red light glistening to alarm.
u The RS-232 standard connector makes it possible to manage on line and monitor in another place.
u The machine adopts 19”standard shelf and it can work with the voltage from 85V to 254v or -48V DC.
u Support dual power supplies hot backup, hot plug in the filed.
