QDD-400G-DR4-S — QSFP-DD 400 Gbps

The Cisco QDD-400G-DR4-S is a QSFP-DD 400 Gbps transceiver compliant with IEEE 400GBASE-DR4, using single-mode fibre (SMF) in a parallel configuration via an MPO-12 (APC) connector. Its reach is 500 metres, with an operating range of 0 to 75 °C, suited to campus datacenter or hyperscale deployments.

With its DR4 architecture across four parallel 100G lanes and MPO-12 parallel fibre cabling, this module is well suited for interconnects between rooms or between nearby buildings within 500 m. It differs from the FR4 by using an MPO cable and a four-lane parallel fibre architecture. Genuine Cisco hardware, manufacturer warranty.
