DP04QSDD-ER1 — QSFP-DD 400 Gbps

The DP04QSDD-ER1 is a Cisco 400 Gbps QSFP-DD module compliant with the OIF 400ZR standard, offering a reach of 45 km over single-mode fiber (SMF) via a duplex LC (UPC) connector. Its operating temperature range of 15 to 75 °C and 400ZR compliance make it a reference coherent transceiver for medium-distance datacenter interconnection.

Designed for DCI (Datacenter Interconnect) architectures requiring 400 Gbps over 45 km, the DP04QSDD-ER1 targets operators and cloud providers deploying very high-throughput inter-site links based on the open OIF 400ZR standard. Its 45 km reach differentiates it from 400G transceivers oriented toward short reach or ultra-long haul. Genuine Cisco hardware, manufacturer warranty.
