SDU-RFoG-F01.PDF Product Description： The SDU RFoG F series is mainly used for RFoG network. “OBI-Free” R-ONU eliminate the Optical Beat Interferences(OBI) that has been an issue in the traditional RFoG deployments. 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.   Features： 1) Support downstream optical AGC, The control range is -6~+2dBm; 2) Burst mode is supported； 3) OBI-Free technology on this model supports up to 16 R-ONUs transmitting into a single optical input; 4) 0.2nm as one step, and the automatic control of transmitting wavelength can be reached by the temperature change randomly.
