850nm SR4 100G QSFP28 Transceiver
Cisco Compatible QSFP-100G-SR4 100GBASE-SR4 QSFP28 850nm MMF 100m
MPO Optical Transceiver
Product Description
Olinkcom's 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.
