QDD-4X100G-FR-S — QSFP-DD 400 Gbps

The QDD-4X100G-FR-S is a Cisco QSFP-DD module delivering 400 Gbps aggregate throughput via 4 lanes of 100 Gbps over single-mode fiber (SMF), with an MPO-12 (APC) connector for parallel fiber transmission. Its 2 km reach makes it a very high-density solution for interconnecting spine or core equipment at short to medium distances.

This transceiver is designed for next-generation datacenters requiring 400 Gbps per port in a compact QSFP-DD form factor, with an extended operating temperature range of 0 to 75 °C. It is suited to connections between core routers, spine switches, and high-performance storage systems. Genuine Cisco hardware, manufacturer warranty.
