CATV Inline EDFA

Lightem LA52 Inline EDFA is working in single wavelength in CATV system. Features low noise figure, large saturation output power, Lightem LA52 CATV inline EDFA can be applicable in the group center, substation and trunk circuit. n
Lightem LA52 adopts the premium grade pump laser and America OFS erbium-doped optical fiber. The pump laser is well protected with the complete control of APC, ACC and ATC circuitry; together with ventilation and heat control the pump laser is running in a control environment. The RS232 and RJ45 port offer serial communication and SNMP network port. The work status of equipment is shown on the LCD display, with warning signal; Optical loss, laser operating status etc. All the parameters can be set via the LCD display, or can be set with RS232 or SNMP.

 

  • Extra low noise index
  • High output, high reliability
  • APC, ACC, ATC controlled selection
  • Powerful RS232 supervisory instruction
  • Three exterior option: 1U (19” stander), 3D (12.4”, 3U, Desk-type) and modulator
  • Standard RS232 communication interface, SNMP network management function
  • Application of 3D models to adapt to laboratory Excellent P/P ratio
