DWDM Inline EDFA

Lightem LDWA52 Gain flatness Line EDFA, adopts optimized design of optical path and high-quality GFF, flatness of gain spectrum <1.0dB (typical value. <0.8dB), it can completely satisfy the requirement of DWDM system boost EDFA which needs gain flatness and high output power. It can also be applied in WDM CATV system for video, audio and data transmission.

LDWA52 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 [li]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 Main application
  • Line amplify in DWDM system
  • WDM fiber CATV system, need low input line and second-grade service area
  • FTTP, FTTH
