Cisco QSFP-100G-SR4-S Compatible 100GBASE-SR4 QSFP28 850nm 100m OM4 DOM MPO-12 Parallel MMF Optical Transceiver Module, 4x 25G-SR

100G QSFP28 SR4 transceiver

For connections inside the data hall, nothing beats the economics of SR4. This QSFP28 module delivers 100G over OM4 multimode fiber to 100 meters, coded and burn-in tested to behave exactly like the Cisco QSFP-100G-SR4-S.

Every unit is programmed for Cisco QSFP-100G-SR4-S compatibility and traffic-tested on real switching platforms before shipment. Custom coding for other brands is available on request at no extra cost.
