1550nm Internal Optic Transmitter
1550nm Internal Optic Transmitter adopt the imported DFB laser named SEI and so on.
The internal RF driving amplifier and controlling circuit of this machine can ensure the best C/N. 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, 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.
The RS-232 standard connector makes it is possible to manage on line and monitor in another place.
1550nm Internal Optic Transmitter adopts 19”standard shelf and it can work with the voltage from 110V to 254V.
