Fiber Optic Products / Fiber Optic ReceiversDuplex LC 100GBASE-LR4 1310nm 10km 100G QSFP28LR4The 100G QSFP28 LR4 optical transceiver integrates the transmit and receive path onto one module. On the transmit side, four lanes of serial data streams are recovered, retimed,and passed on to four laser drivers, which control four electric-absorption modulated lasers (EMLs) with 1296, 1300, 1305, and 1309 nm center wavelengths. The optical signals are then multiplexed into a single-mode fiber through an industry-standard LC connector.On the receive side, four lanes of optical data streams are optically demultiplexed by an integrated optical demultiplexer. Each data steam is recovered by a PIN photodetector and transimpedance amplifier, retimed, and passed on to an output driver. This module features a-pluggable electrical interface, low power consumption, and 2-wire serial interface.Features:Duplex LC receptacle optical interfaceSingle +3.3V power supply-pluggable QSFP28 MSA form factorAC coupling of CML signalsTransmitter: cooled 4x25Gb/s CWDM EML TOSA (1271, 1291, 1311, 1331nm)Receiver: 4x25Gb/s PIN ROSALow power dissipation (Max: 4W)Built in digital diagnostic functionOperating case temperature range:0 to 70Compliant with 100GBASE-LR4I2C Communication InterfaceApplications:100GBASE-LR4 QDR and DDR interconnects100G Datacom connectionsStandardsCompliant with IEEE 802.3baCompliant with QSFP28 MSA hardware specificationsCompliant with
