1550nm optical transmitter, 6 dB output

The transmitting modules of this machine adopt the imported DFB laser from SEI manufacturer.

The internal RF 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 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, therewill be a red light glistening to alarm.

The RS-232 standard connector makes it is posiible to manage online and monitor in another place.

The machine adopts 19" standard shelf and it can work with the voltage from 90V to 265V

Features

  • Low chirp, high linearity DFB laser
  • Dual module RF driver, high efficient laser pre-distortion adjustment
  • Perfect APC, ATC closed loop control
  • Intuitionistic modulation status display
  • Casing temperature auto-control, ensure the long life of the laser
