Description
XGS-PON SFP ONU transceiver is a high performance transceiver module for single fiber communications. It is designed to meet ITU-T G.9807.1 requirements for optical line terminal applications.
The 1270nm DFB transmitter has automatic power control (APC) function and temperature compensation circuitry to ensure stable optical power and extinction ratio over all operating temperature range. The transmitter meets Class 1 eye safety per IEC60825 and CDRH standards.
The receiver has a hermetically packaged APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with CML compatible differential outputs.
The module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias current, module temperature, and supply voltage.
XGS-PON SFP ONU transceiver Key Selling Points
- 10G symmetric XGS-PON performance
- Single fiber bidirectional transmission
- High sensitivity APD receiver
- Real-time monitoring with DDM
- Low power consumption and stable operation
- Compatible with standard SFP+ slots
