The 100G QSFP28 SR4 optical transceiver integrates the transmit and receive path onto one module. It converts parallel electrical input signals into parallel optical signals, by a driven Vertical Cavity Surface Emitting Laser (VCSEL) array. The transmitter module accepts electrical input signals compatible with Common Mode Logic (CML) levels. All input data signals are differential and internally terminated. The receiver module converts parallel optical input signals via a photo detector array into parallel electrical output signals. The reCML) levels. All data signals are differential and support a data rates up to 27.9525Gb/s per channel.ceiver module outputs electrical signals are also voltage compatible with Common Mode LogicOn This module features a hot-pluggable electrical interface, low power consumption, and 2-wire serial interface. Features: MTP/MP0 optical connector Single +3.3V power supply Hot-pluggable QSFP28 MSA form factor Up to 100m OM4 MMF Distance 4x28G Electrical Serial Interface (CEI-28G-VSR) AC coupling of CML signals Low power dissipation(Max:3.5W) Built in digital diagnostic function Operating case temperature range:0 to 70 Compliant with 100GBASE-SR4 I2C Communication Interface Applications: 100GBASE-SR4 Infiniband QDR/DDR/SDR 100G Datacom connections Standards: Compliant with IEEE 802.3ba Compliant with QSFP28 MSA hardware specifications Compliant with RoHS
