CATV Booster EDFA

Lightem LA51 CATV Booster EDFA is working in single wavelength in CATV system. In order to avoid distortion, the operation wavelength of External Modulation optical transmitter is usually 1548~1563nm. Features low noise figure, large saturation output power, Lightem LA51 CATV Booster EDFA can be applicable in the group center, substation and trunk circuit.

Lightem LA51 features complete control of APC, ACC and ATC, perfect design in the ventilation and heat output ensure the long life of pump laser and high reliable work. RS232 and RJ45 offer serial commutation and SNMP network port. The LCD of front panel offers the work status of equipment’s warning signal; Optical loss, laser operating status etc. All the optical port can be set in the front panel, or can choose set in the back panel.

 

  • Low noise figure
  • High output power
  • Power adjustment via the button on front panel (optional)
  • RS232 commutation and SNMP network management optional
  • Excellent P/P ratio
  • Available of 19″ rugged housing
