DP04QSDD-HK9 — QSFP-DD 100/200/300/400 Gbps

The DP04QSDD-HK9 is a Cisco QSFP-DD coherent transceiver supporting line rates from 100 to 400 Gbps over duplex single-mode fiber via an LC (UPC) connector, up to 100 km. Like its sibling DP01QSDD-LK9, it operates within the same thermal envelope (+15 to +78 °C), but its distinct part number corresponds to a different power density or modulation variant tailored to specific deployment scenarios.

This module targets high-capacity coherent optical transport architectures, including operator backbone networks and long-distance data center interconnects. Its native compatibility with Cisco chassis and rate flexibility reduce the number of distinct SKUs to manage in inventory. Genuine Cisco hardware, manufacturer warranty.
