The OFQ212G10C-FP4 QSFP28 optical transceiver is intended for up to 10km reach service with four-lane 25.78125G data rate. It is based on 3.3V DC power supply and operates in the commercial temperature range. It is compliant with QSFP MSA 、SFF-8436 、SFF-8636 and PSM4 MSA. Digital diagnostic functions are available via I2C interface,and the control functions can be achieved by LVTTL interfaces on the host,mainly including Module Select(ModSelL)、Module Reset(ResetL)、 Low Power Mode(LPMode). The transceiver incorporates a four-laser array which is usually DFB 、four-PIN diode array 、a high performance CDR integrated four drivers and TIAs IC separately. The differential AC coupled Tx and Rx data interfaces are CML compatible.
