The CZGU-F3412-SB2DA bi-directional transceiver is the high performance module for single fiber communications by using 1310nm 1.25Gbps burst mode transmitter and 1490nm 2.5Gbps continuous receiver. It is Optical Network Unit (ONU) for ITU-T G.984.2 Class B+. The optical transceiver is compliant with Multi-Source Agreement (MSA) Small Form Factor (SFF) 2x10 footprint.The transmitter section uses a 1310nm DFB laser diode with automatic power control (APC) function and temperature compensation circuitry to ensure stable extinction ratio overall operating temperature range, and full IEC825 and CDRH class 1 eye safety. The receiver has a hermetically packaged PIN-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with CML compatible differential outputs.
