DWDM PreAmp EDFA

LDWA53 Gain flatness PreAmp 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 Gain flatness Pre-EDFA worked in which features low noise figure and high gain >40dB. It can also be applied in WDM CATV system for video, audio and data transmission. With the completely 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 work status of equipment’s warning signal; Optical loss, laser operating status etc can be displayed on the front LCD panel.

 

  • The gain flatness <1.0dB (Typ.=0.7dB)
  • High-gain >40dBm (Pin= -30dB)
  • Low noise figure – Broad operating wavelength
  • APC, ACC, ATC – Perfect RS232 communication interface and SNMP function
  • Excellent P/P ratio
