Cisco QSFP-100G-SR4-S Compatible QSFP28 100GBase-SR4 100M 850nm MPO Connector MMF DOM MSA Compliant

• Product Overview

The 100GBASE-SR4 QSFP28 transceiver is a parallel 100G optical transceiver. It provides increased port density and total system cost savings. This 100G QSFP28 full-duplex optical transceiver uses eight multimode fibers for 100G dual-way transmission over 850nm, offers 4 independent transmit and receive channels, each capable of 25 Gbps operation for an aggregate data rate of 100 Gbps on 100 meters over OM4 MMF.

100G QSFP28 SR4 is a standard published by IEEE. It can support a transmission distance up to 70m over OM3 and 100m OM4 with a MTP interface. 12-fiber MTP OM3/OM4 trunk cables are suggested to be used with QSFP-100G-SR4 modules. 100Gbase-SR4 QSFP28 is the most popular QSFP28 module according to research.

100GBASE-SR4 QSFP28 transceiver converts parallel electrical input signals into parallel optical signals by a driven VCSEL array. The transmitter module accepts electrical input signals compatible with CML (common mode logic) 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 receiver module outputs electrical signals are also voltage compatible with CML levels. All data signals are differential and support a data rates up to 25 Gbps per channel.

QSFP28 SR4 100G Optical transceiver module are designed for use in 100 Gigabit Ethernet links over multimode fiber. They are compliant with the QSFP28 MSA and IEEE 802.3bm 100GBASE-SR4 and CAUI-4. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA.
