1. Product Overview
WR-1201-JK-TD series FTTB Node is mainly used for RFOG network. Its return path laser can work in burst mode. The upstream output optical wavelength can be set as CWDM standard wavelength to shield the OBI effectively.
 
2. Performance Character
  • Operating frequency: 5~85/110-1218MHz; support smoothly update on the spot (5~204/258-1218MHz).
  • Support downstream optical AGC, whose control range is 0~-5/-6/-7dBm adjustable.
  • Adopt electric adjusting mode for both EQ and ATT circuit, using LED displaying screen to modify directly.
  • Upstream output optical wavelength is optional (or specified by the user).
  • RFoG can be set as burst mode or continual mode.
  • Support DOCSIS 3.0 system and OBI Free
