QSFP-H40G-AOC2M Description
QSFP-H40G-AOC2M is a Cisco 40GBASE QSFP direct-attach active optical cable in the Cisco QSFP 40G portfolio, built for short 40G links between Cisco QSFP ports within or across adjacent racks. This 2-meter QSFP-to-QSFP AOC cable supports 40 Gigabit Ethernet connectivity, uses a brown pull tab for length identification, and follows Cisco's QSFP connector module profile with maximum 13.5 x 18.4 x 72.4 mm connector-module dimensions and a module weight of 100 grams or less.

Application Scenarios
Use QSFP-H40G-AOC2M for short QSFP-to-QSFP routes where 1 meter does not clear the cable manager but 3 meters would create avoidable loops. It fits same-rack switch, fabric extender, controller, or line-card connections after the routed path has been measured.
The brown pull tab gives warehouse and rack teams a visible cue for the 2-meter length, but the receiving check should still compare the full product ID against the purchase order.
Use this SKU as a short cable spare only where the site has standardized on 2-meter 40G AOC paths. For mixed cable trays or cross-rack routing, review longer Cisco AOC lengths before buying spares.

- QSFP-H40G-AOC2M is the short-length option to review when 1 meter is too tight but the installation should avoid 3 meters of cable in a dense rack.
- Cisco documents the same QSFP-end diameter, bend-radius value, face plate distance, jacket material, and jacket color for the 1-meter, 2-meter, and 3-meter AOC options.
- The brown pull tab helps distinguish the 2-meter cable from beige 1-meter and orange 3-meter versions during receiving.
- Device and software compatibility still needs a Cisco matrix check before technical fit, order, support entitlement, or deployment approval. Related SKU checks: QSFP-H40G-AOC3M. Related comparison SKUs: QSFP-H40G-AOC1M.
Selection Guide
1. Use it for controlled short patching
Select QSFP-H40G-AOC2M when the routed path needs a little more reach than 1 meter but must stay tidy at the front of the rack. Measure through the actual cable manager, not only between port faces.
2. Keep breakout requirements separate
This cable is a straight QSFP-to-QSFP 40G assembly. For one QSFP port to four SFP+ endpoints, quote Cisco breakout AOC part numbers instead.
3. Check host support before the order
Match the target switch, controller, fabric extender, or line card to Cisco’s 40-Gigabit Ethernet compatibility documentation. The purchase should not rely on cable family alone.
4. Keep the 2-meter SKU visible
Use QSFP-H40G-AOC2M exactly for quote, stock, warranty, and shipping requests. Similar 40G AOC SKUs are easy to confuse when the bill of materials contains several short lengths.
