Product details

Field Two RF Output Ports AGC Optical Receiver

Outdoor Optical Receiver is one kind of useful field optical receiver designed for meeting network fiber transformation. The product has one to two RF output ports and optical path AGC function. When +1dBm~-6dBm receives, the output can be kept at 108 dBµV±1dB(two-path). The shell is water-proof aluminum casting shell and suitable for field work.

Hfc Optical Node Features

  • 45MHz to 862MHz platform bandwidth and 1310, 1550 dual design platform.
  • Perfect surge suppress circuit cooperating with high-pass filter has strong thunder-proof ability and the ability of preventing surge shock.
