XGPON/XGSPON OLT/ONU transceivers

XG-PON1 and XGS-PON optical transceivers are housed in SFP+/XFP package. The Transmit and Receive signals operate on different wavelengths (1270nm/1577nm) allowing bi-directional operation over a single fiber. The XG-PON1 transceivers are single fiber bi-directional data links with asymmetric 9.953Gbps/2.488Gbps upstream and 2.488Gbps/9.953Gbps downstream. The XGS-PON transceivers are single fiber bi-directional data links with symmetric 9.953Gbps upstream and 9.953Gbps downstream. The OLT optical transceivers use 1577nm continuous-mode transmitter with EML laser and 1270nm high sensitivity burst-mode APD-TIA receiver. The ONU optical transceivers use 1270nm burst-mode transmitter with DFB laser and 1577nm high sensitivity continuous-mode APD-TIA receiver.
