QSFP-H40G-AOC3M Description
QSFP-H40G-AOC3M is the Cisco 3-meter 40G QSFP active optical cable for direct QSFP-to-QSFP Ethernet links.
This length is useful when a 2-meter cable is too short but the rack layout still needs a tidy short optical run. It is not a breakout cable, and it should be checked against the target Cisco platform and software release before the purchase order is approved.
For buying review, confirm the 3-meter route, QSFP host ports, compatibility matrix result, and whether nearby 2-meter or 5-meter cable lengths would fit better. Layer23-Switch can help check price, stock, warranty support, and shipping timing for the exact AOC SKU.

Application Scenarios
Use QSFP-H40G-AOC3M when two compatible Cisco QSFP interfaces sit close enough for a 3-meter run and the design calls for an active optical cable instead of a passive copper cable. The short fixed length helps reduce spare cable buildup in dense top-of-rack or aggregation racks.
This SKU is useful when a bill of materials must stay inside Cisco-listed 40G QSFP cable options. Engineers should still match the target switch or line card against Cisco’s compatibility matrix, because the supported software release depends on the platform.
QSFP-H40G-AOC3M can be considered when a short 40G connection needs a lighter optical cable form than comparable copper direct-attach cables. Before purchase, confirm the physical cable path, bend radius, and face plate clearance in the rack.

- Choose the 3-meter SKU when the cable path is longer than a 2-meter run but does not need the extra slack of the 5-meter version.
- The 2-meter, 3-meter, and 5-meter AOC options keep the same QSFP-end cable diameter and bend-radius values in Cisco’s cable-dimension table.
- Pull tab color is useful for warehouse receiving and rack-side identification, but compatibility should still be checked by platform and software release.
- Ask for price and stock by exact SKU, because the same Cisco 40G AOC family includes multiple lengths that are easy to mix in a purchase request.
Selection Guide
1. Match the cable length to the actual rack path
Select QSFP-H40G-AOC3M when the measured route between the two QSFP ports fits a 3-meter cable with service slack. Avoid using a longer cable only because it is available, since excess fiber routing can complicate cable management in high-density racks.
2. Validate the Cisco platform before ordering
Check the Cisco compatibility matrix for the exact switch, supervisor, line card, and software release. Cisco lists QSFP-H40G-AOC3M across multiple Catalyst and Nexus entries, but the release requirement is platform-specific.
3. Separate direct-attach AOC needs from breakout needs
Use this SKU for QSFP direct-attach 40G connections. If the design needs one QSFP port to split into four SFP+ links, evaluate Cisco’s QSFP-to-4xSFP+ breakout AOC SKUs instead of this cable.
4. Confirm commercial requirements with the exact SKU
For quote, warranty, and shipping checks, use QSFP-H40G-AOC3M exactly in the request. Similar 40G AOC SKUs differ mainly by length, so the wrong line item can create receiving and installation delays.

Our internal vendor satisfaction survey gave Layer23 high marks. Would have liked a tracking update sooner, but the product is great.
Asked about a future order — they remembered our previous purchase and made the new quote easy.
Asked our reseller contact to confirm — fully legit. Layer23 sources genuine gear. Minor delay in delivery, but everything was in order.
