WR1201JKCH-TD RFoG Node is mainly used for RFoG network. Its return path laser can work under burst mode. In upstream channel, it can adjust 4 output optical wavelengths (0.5nm stepping). 4 different basic CWDM wavelengths as a group, the same basic CWDM wavelength is applied to four equipment, set the output wavelength of these equipment with 0.5 stepping accordingly (from 1~4 CH), which can effectively realize OBI free.
● Output wavelength of the return path is adjustable, 4 wavelengths settable with 0.5nm stepping.
● RFoG can be set as burst mode or continuous mode.
● Support DOCSIS 3.1 system and OBI Free.
● 1.2GHZ frequency band, multiple frequency divisions are optional, support smooth upgrade on site
● Optical AGC，control range -5/-6/-7/-8～0 adjustable.
● Electronic control RF ATT：0～18，1dBstepping.
● Electronic control EQ：0～15，1dBstepping.
● Downstream output level can reach 108dBμV, excellent output distortion index.
● LED can display and set various parameters.
● Built-in WDM, single fiber dual wave.
● Excellent surge and ESD protection.
