About the Cisco QSFP-H40G-AOC Cisco SFP/SFP+/QSFP/XFP transceiver
QSFP+ connector ends on both terminations ensure compact, tool-free rack integration and reliable cable management in dense switch environments. The Cisco QSFP-H40G-AOC is an active optical cable assembly delivering 40 Gbps aggregate throughput across 4 parallel lanes, each operating at 10 Gbps. Operating at 850 nm wavelength with VCSEL technology, this transceiver uses multimode fiber (OM3 / OM4) to span distances from 1 m to 10 m, accommodating both short intra-rack links and moderate inter-cabinet runs without signal regeneration.
Built to the IEEE 802.3ba 40GBASE standard, the QSFP-H40G-AOC is Cisco Manufacturer Part Number QSFP-H40G-AOC and passes Cisco IOS / NX-OS integrity checks, confirming genuine firmware validation. Digital Optical Monitoring (DOM) support enables real-time signal diagnostics and proactive fault detection. Hot-swap capability allows seamless module replacement during operation, while power consumption remains below 1.5 W per end. RoHS compliance aligns with enterprise environmental mandates. Operating across 0°C to 70°C, this module suits both standard datacenters and moderately temperature-controlled facilities. A network engineer or infrastructure team standardizing on Cisco high-speed fabrics will recognize this cable's role in eliminating transceiver-pair inventory complexity and reducing total cost of ownership.
Platform Compatibility & Deployment Scenarios
- Cisco Nexus switches and fabric extenders requiring 40 Gbps inter-switch links
- Cisco Catalyst platforms leveraging QSFP+ uplink modules for campus aggregation
- ASR and UCS environments consolidating storage and compute traffic over optical lanes
- Intra-rack and inter-cabinet cabling where cable lengths up to 10 m eliminate costly fiber spool and termination labor
- Mixed-mode deployments integrating legacy OM3 and modern OM4 multimode infrastructure
