  • We use noise pump of famous (OCLARO OR JDSU) brand with low distortion, wide bandwidth and high output optical power.
  • We use high performance Erbium-doped fiber, with high energy conversion efficiency; advanced SMT production process with high reliability.
  • Blue VFD Display displaying the operating parameters and fault information accurately.
  • Circuit type EDFA whose noise index is lower than 4 dB (when the input optical power is 0 dB) is mainly used in multistage cascade long distance transmission of primary route.
  • Power type EDFA whose output optical power is 25dB is mainly used in FTTB network of MAN.
  • 16 X 4 dBm
  • 16.4 X 4 dBm
  • 23 X 1 dBm
  • 24 X1 dBm.
