DWDM Booster EDFA

Lightem LDWA51 Fiber optic EDFA product series features gain spectrum inclination, provide Gain flatness Boost in C-Band (1528~1564nm). It meets DWDM system C-Band boost EDFA ’s requirement – gain flatness and high output power requirement It is optimized in design of the optical path and high-quality GFF, as well as gain spectrum <1.0dB (typ. <0.8dB) in the whole C-Band. It can also be applied to WDM fiber optic CATV system for transmitting multi-wavelength video, audio and data. LDWA51 front LCD panel provides features include work index of all equipment include, alarm, optical loss, laser operating status.

 

  • Low noise, high performance and high reliability
  • Broad operating bandwidth – The gain flatness less than 1.0dB (Typ.=0.8dB)
  • Total output power: 20~2500mW optional – At most 64 ports output
  • OADM (Add/Drop) In put port and out put port can choose OADM (Add/Drop)
  • The control of laser APC, ACC, ATC – Perfect RS232 communication interface and SNMP function
  • Highly active rooms set and use conveniently – Excellent P/P ratio
