1550 nm erbium doped fiber amplifier GFD1550-E with 19"standard shelf
- This machine adopts imported optical module, pump laser and erbium doped amplifier.
- 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 for a long time.
- The internal micro-processor software has many functions such as laser monitoring, number 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.
- Support 3 operation modes: constant output, constant gain and constant pump current
- The RS-232 standard connector makes it is possible to manage on line and monitor in another place.
- The machine adopts 19"standard shelf and it can work with the voltage from 85V to 254V or -48V DC.
