| 1. Product Overview
OPR-1201JKBH-TD FTTB Node is mainly used for RFoG network. Its return path laser can work under burst mode.
2. Performance Character
(1) Operating frequency: 5~85/110-1218MHz; support smoothly update on the spot (5~204/258-1218MHz).
(2) Support optical AGC downstream, whose control range is 0~-5/-6/-7/-8dBm adjustable.
(3) Adopt electric adjusting mode for both EQ and ATT circuit, using LED displaying screen to modify directly.
(4) RFoG can be set as burst mode or continuous mode.
(5) Support DOCSIS 3.1 system and OBI Free.
