Cisco 400G QSFP-DD FR4 Transceiver Module

The Cisco 400G QSFP-DD FR4 Transceiver Module is a high-density optical module engineered for 400 Gigabit Ethernet interconnect over single-mode fiber at distances up to 2 kilometers. This module leverages the QSFP-DD form factor to deliver four lanes of 100G each, enabling seamless integration into Nexus 9000 series cloud and data center switching platforms without requiring additional optics management complexity.

Designed for enterprise-class reliability, the FR4 variant operates within standard C-band wavelengths and is optimized for metropolitan-range interconnects between adjacent data centers and cloud infrastructure nodes. The module supports both short-reach intra-campus deployments and extended single-mode reach applications typical of modern hybrid cloud environments.

Adoption across enterprise data center operators has accelerated since its introduction, driven by the need for higher port density, reduced power consumption per gigabit, and compatibility with existing Nexus 9000 deployments. The module integrates digital diagnostics and monitoring capabilities to support operational visibility and proactive infrastructure management.

Ideal for

• Data center fabric interconnect between Nexus 9000 switches in adjacent buildings or campuses
• Multi-site cloud infrastructure with 2km single-mode connectivity between primary and secondary facilities
• High-density 400G core spine-leaf network deployments requiring QSFP-DD form factor efficiency
• Metropolitan area network (MAN) extensions between colocation facilities within city boundaries
• Financial services network backhaul with deterministic latency and carrier-grade reliability
• Research and higher education campus-wide 400G backbone provisioning
