QSFP-H40G-AOC15M Description
QSFP-H40G-AOC15M is the Cisco 15-meter 40G QSFP active optical cable for fixed QSFP-to-QSFP links across longer rack-row paths.
This is a routed-cable-length decision, not just a speed match. It makes sense when 10 meters is short, 20 meters adds too much slack, and the design still prefers one Cisco AOC assembly instead of separate transceivers and patch cords.
Before buying, confirm the measured path through cable managers, the target Cisco host, software support, and the exact 15-meter model. Layer23-Switch can help check price, stock, warranty support, compatibility, and shipping timing.

Application Scenarios
Use QSFP-H40G-AOC15M when the installed route between compatible Cisco QSFP ports must pass through rack managers or overhead trays and a 10-meter cable would be tight. The 15-meter length should be selected from the measured route, not from an estimated cabinet distance.
This active optical cable is useful when a copper assembly would be difficult to dress across the same path. Review the documented 3.5 mm cable diameter, 60 mm bend radius, and 115 mm face plate distance with the rack layout before shipment.
Keep this SKU in a separate spare pool when the site repeatedly uses 15-meter 40G QSFP links. The black pull tab can help receiving teams identify the length, but the purchase order should still show the exact Cisco product ID.

- QSFP-H40G-AOC15M is the mid-length option to review when 10 meters is short and 20 meters would add avoidable slack.
- Cisco’s cable-dimension table keeps the same QSFP-end diameter, bend-radius value, face plate distance, jacket material, and jacket color across the 10-meter, 15-meter, and 20-meter AOC choices.
- The black pull tab supports warehouse identification for the 15-meter cable, but the exact SKU should drive the quote and receiving check.
- Host support remains a separate compatibility task tied to the Cisco platform and software release.
Selection Guide
1. Measure the routed path first
Use QSFP-H40G-AOC15M only after the cable route has been measured through the same managers and trays that will be used during installation. The extra reach is helpful for rack-row paths, but unused length still has to be managed.
2. Keep it out of breakout BOMs
This SKU is for one 40G QSFP port at each end. If the design fans out one QSFP port into four SFP+ interfaces, quote a Cisco QSFP-to-4xSFP+ breakout cable instead.
3. Validate the host and release
Check the target switch, controller, fabric extender, or line card against Cisco’s 40-Gigabit Ethernet compatibility documentation before approving the order. A valid Cisco cable length still has to be supported by the host platform.
4. Quote with the full model number
Use QSFP-H40G-AOC15M exactly for price, stock, warranty, and shipping requests. Similar Cisco 40G AOC part numbers differ mainly by length, so the full model number should stay visible through quote, purchase, and receiving.
