WT-QSFP28-SR4 is a four-channel, pluggable, parallel-fiber QSFP28 optical transceiver designed for IEEE 802.3bm compliant 100GBASE-SR4 applications, as well as 40 Gigabit Ethernet and InfiniBand FDR/EDR applications.

This QSFP28 full-duplex optical module provides 4 independent transmit and receive channels, each operating at 25.78125 Gbps, delivering an aggregate data rate of up to 104 Gbps. It supports transmission distances of up to 70 meters over OM3 multimode fiber.

The module is designed to operate over multimode fiber systems using an 850nm VCSEL (Vertical-Cavity Surface-Emitting Laser) array. A ribbon fiber cable with MPO/MTP™ connector plugs directly into the QSFP28 module receptacle.

The QSFP28 SR4 is a parallel transceiver that offers higher port density and significant overall system cost savings.
