QSFP-H40G-AOC3M Description
The QSFP-H40G-AOC3M is a Cisco 40GBase-AOC QSFP direct-attach active optical cable for 40 Gigabit Ethernet links between QSFP ports in the same rack row. The 3 m assembly has an orange pull tab, a 3.5 mm QSFP-end cable diameter, a 60 mm bend radius and a 115 mm face plate distance, and it draws 1.5 W at each end across a 0 to 70 C operating range. Host support depends on the platform and software release listed in the Cisco 40-Gigabit Ethernet Transceiver Modules Compatibility Matrix.

Application Scenarios
In a rack row, the cable runs from a top-of-rack switch to an aggregation switch a few racks away, carrying 40 Gigabit Ethernet over a thin optical jacket instead of a heavy copper bundle.
A Nexus fabric extender in an adjacent rack can reach its parent switch over the 3 m length, and the lighter cable keeps airflow paths clear across dense rear-of-rack cabling.

QSFP-H40G-AOC3M is the 3 m orange-tab member of this 40GBase-AOC group, and QSFP-H40G-AOC2M and QSFP-H40G-AOC5M match it on 3.5 mm QSFP-end diameter, 60 mm bend radius and 115 mm face plate distance, so they differ only in fixed length and pull tab color (brown at 2 m, gray at 5 m). A path of 2 m or less fits QSFP-H40G-AOC2M, and a path between 3 m and 5 m needs QSFP-H40G-AOC5M. Active optical cables in this family run on to 30 m, while a one-to-four split into SFP+ ports needs a breakout cable such as QSFP-4X10G-AOC10M.
Ordering Checklist
- Host support: Confirm the target Cisco switch or line card and its QSFP+ port are listed for QSFP-H40G-AOC3M in the Cisco Optics-to-Device Compatibility Matrix. A cable that fits the QSFP cage can still be unsupported on a given host.
