This GTS-SGU12-20DC Class B+ GPON ONU/ONT SFP SC UPC transceiver module is designed for low cost P2MP FTTx applications. It can fully support the Class B+ ODN application specified by the ITU-T G.984.2 standard and ITU-T G.984.2 Amendent-2006.

The transmitter module uses a DFB laser diode and is fully compliant with IEC60825 and CDRH class 1 eye safety. It contains APC functions, a temperature compensation circuit to ensure compliance with G.984.2 requirement at operating

temperature, data inputs and AC or DC coupling circuit.

The receiver section uses a hermetic packaged APD-TIA (APD with trans-impedance amplifier) and a limiting amplifier. The APD converts optical power into electrical current and the current is transformed to voltage by the trans-impedance amplifier. The differential DATA and /DATA CML data signals are produced by the limiting amplifier. The APD-TIA is AC coupled to the limiting amplifier through a low pass filter.

Digital diagnostics functions are available, as specified in SFF-8472,which provides real-time monitoring of the transceiver temperature, laser bias current, optical power, received optical power and transceiver supply voltage.

Each GPON SFP transceiver module has done sampling test under most famous brands of routers, switches, servers.
