QSFP-H40G-ACU10M Description
QSFP-H40G-ACU10M is the Cisco 10-meter 40GBASE-CR4 QSFP+ active copper direct-attach cable for compatible Cisco QSFP+ ports.
It is a fit when the link should remain a fixed copper assembly but the distance is beyond the short passive DAC range. Keep it separate from AOC cables and passive copper lengths, because the cable type affects routing, compatibility review, and receiving checks.
For purchasing, confirm the 10-meter path, host platform, line card or port type, software release, and whether active copper is the intended medium. Layer23-Switch can help check price, stock, warranty support, shipping timing, and Cisco compatibility.

Application Scenarios
Use QSFP-H40G-ACU10M when the measured path between two compatible Cisco QSFP+ ports needs a 10-meter copper assembly. The active cable design gives buyers a Cisco-listed option for longer copper runs without moving to a separate optics-and-fiber bill of materials.
This SKU fits deployments where the cabling team wants a factory-terminated 40G cable with a defined length, pull-tab color, bend radius, and jacket type. The 10-meter length should be matched to the real tray or ladder route, not estimated from cabinet distance alone.
QSFP-H40G-ACU10M is useful as a direct replacement or spare when the installed network already uses Cisco 40GBASE-CR4 active copper cables. Before ordering, confirm the target platform and software release in Cisco’s compatibility matrix so the spare matches the supported device list.

- QSFP-H40G-ACU10M is the 10-meter active copper option in this Cisco 40GBASE-CR4 QSFP+ direct-attach group.
- QSFP-H40G-ACU7M keeps the active copper design but reduces the fixed cable length to 7 meters.
- QSFP-H40G-CU5M is a shorter passive copper alternative, so it should not be substituted when the design specifically calls for an active 10-meter run.
- The 7-meter, 10-meter, and 5-meter copper options share the same Cisco-listed QSFP-end cable diameter, bend radius, face plate distance, jacket material, and jacket color values.
Selection Guide
1. Choose this cable for a confirmed 10-meter copper path
Select QSFP-H40G-ACU10M when the measured rack route needs 10 meters and the host ports support Cisco 40GBASE-CR4 QSFP+ active copper direct attach. If the path is shorter, compare the 7-meter active cable or passive copper SKUs before locking the order.
2. Keep active copper and passive copper separate
Do not replace this SKU with a passive `QSFP-H40G-CU` cable only because the connector family looks similar. The active and passive Cisco copper DAC lines differ by length coverage and electronics, which can affect both compatibility checks and receiving inspection.
3. Validate the Cisco platform and software release
Use Cisco’s 40-Gigabit Ethernet compatibility matrix to check the exact network device, module, and minimum software release. The same cable can appear across several Cisco platforms, but support is still tied to the host hardware and release train.
4. Quote the exact model for commercial checks
Request price, stock, warranty support, and shipping timing with `QSFP-H40G-ACU10M` exactly. A one-character difference can change the line item from active copper to passive copper, optical AOC, or breakout cable.
