Product Description

1. Product Overview
WR-1201-JKC-TD FTTH Node is mainly used for RFOG network. Its upstream output optical wavelength can be adjusted on the spot to realize the OBI free effectively.
 
2. Performance Character

• Operating frequency: 5~85/110-1218MHz; support smoothly update on the spot (5~204/258-1218MHz).
• Support optical AGC downstream, whose control range is 0~-5/-6/-7/-8dBm adjustable.
• Adopt electric adjusting mode for both EQ and ATT circuit, using LED displaying screen to modify directly.
• Output optical wavelength is 1610nm upstream (or specified by the user) and can be adjusted by button in 0.25nm stepping; totally it can be set 16 wavelengths.
• RFoG can be set as burst mode or continuous mode.
• Support DOCSIS 3.0 system and OBI Free.
