This is a combination of XGS-PON OLT and GPON OLT optical module  in a SFP+ housing. It is designed to support both the XGS-PON OLT and GPON OLT specifications over a single fiber via coarse wave division multiplexing. The XGS-PON bi-directional link is configured with 1270nm abd 1310nm optical burst mode receivers incorporate APD/TIA optics for maxmum sensitivity. The 10G transmitter incorporates a 1577nm EML laser assembly and the 2.5G transmitter incorporates a 1490nm DFB laser assembly. The transmitters can be controlled by the LVTTI Tx_Disable function and the receivers incorporates the LVTTL Rx_SD output.

The optical module is designed to support up to 32/64 subscribers over distances of up to 20km. It is FDA 21 CFR1040.10 and IEC 60825-2Class I laser safety compliant and meets the EEC Directive 2002/95/EC for RoHS compliance.
