High Power Catv 1550nm Edfa

High Power Catv 1550nm Edfa

The transmitting modules of this machine adopt the imported DFB laser named Agere (ORTEL, Lucent), Mitsubishi, Fujitsu, AOI, 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 the thermoelectric refrigeration device of the laser module assures the user of the best quality and stable working for a long time. The internal microprocessor 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 online and monitor in another place. The machine adopts a 19" standard shelf and it can work with the voltage from 110V to 254V.
