Product Description

GPON ONU SFP Transceiver Module

Class B+ LC APC Connector Receptacle

Generic Compatibility, RoHS FCC CE REACH.





This GTS-BGU12-20DC GPON ONU SFP Class B+ transceiver module is designed for Gigabit-capable Passive Optical Network (GPON) transmission. 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 1310nm 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 1550nm 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.

The module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias current, module temperature, and supply voltage. Calibration and alarm/warning threshold data are written and stored in the internal memory (EEPROM).
