Widely used in fiber switches, routers, NIC, server or other fiber optic equipments with 100Gb QSFP28 ports. 100GBASE-SR4 transceiver modules QSFP28 SR4 transceivers are capable of transmitting 4 x 25G channels simultaneously up to 70m over OM3 or 100m over OM4. The modules use 8 fibres (4 fibre pairs) with an MPO interface and a 12-fibre MPO-style MTP® connector (4 fibres unused), which makes them capable of breaking out to 4 x 25G ports The QSFP-100G modules are our latest generation of 100G transceiver modules solution based on a QSFP form factor.
