QSFP-4X10G-AOC10M Description
QSFP-4X10G-AOC10M is the Cisco 10-meter QSFP-to-4xSFP+ active optical breakout cable for one 40G port to four 10G links.
This part belongs in a breakout design, not a normal QSFP-to-QSFP 40G link. It is useful when the port plan needs four SFP+ endpoints from one Cisco QSFP port while avoiding separate optics and patch cords.
Before ordering, confirm the host platform, breakout mode, software support, 10-meter route, and SFP+ endpoint layout. Layer23-Switch can help check price, stock, warranty support, shipping timing, and Cisco compatibility for the exact breakout cable.

Application Scenarios
Use QSFP-4X10G-AOC10M when the design calls for one compatible Cisco 40G QSFP interface to connect to four Cisco 10G SFP+ interfaces. It fits aggregation, fabric extender, or migration projects where the upstream port is 40G and the downstream devices still use 10G SFP+ links.
The 10-meter active optical format is useful when the route is longer than the shorter 1-meter to 7-meter breakout AOC options. Check the actual cable path through managers and trays so the 7-meter breakout point, bend radius, and SFP-end fanout all have enough space.
This model helps standardize a Cisco breakout line item when a BOM needs a fixed 10-meter QSFP-to-4xSFP+ active optical cable. Buyers should quote the full SKU to avoid receiving a QSFP-to-QSFP AOC or an active copper breakout cable with a similar part number.

- Choose the 10-meter AOC breakout SKU when a 7-meter optical breakout cable is short for the routed path but the design still needs optical rather than active copper cable.
- QSFP-4X10G-AOC10M and QSFP-4X10G-AC10M have the same listed cable length and breakout location, but Cisco identifies one as active optical and the other as active copper.
- The optical breakout cable uses smaller listed cable diameters at both the QSFP and SFP ends than the active copper 10-meter breakout option.
- Pull tab color helps receiving and installation teams separate nearby cable lengths, but the purchase request should still use the exact product ID.
Selection Guide
1. Use this SKU only for a real 40G-to-4x10G breakout requirement
QSFP-4X10G-AOC10M is not a QSFP-to-QSFP direct-attach cable. Select it when one 40G QSFP host port must fan out to four 10G SFP+ ports, and confirm the Cisco platform supports breakout operation on the target ports.
2. Measure the cable path before approving the 10-meter length
The 10-meter length should be checked against the routed path, not just the straight cabinet distance. The breakout point is 7 meters from the 40G end, so the rack layout must leave enough distance for the four SFP+ legs to reach their target ports cleanly.
3. Validate platform and software compatibility
Cisco compatibility documentation should be checked for the exact switch, controller, line card, and software release. A valid Cisco cable SKU can still be wrong for a specific chassis, port group, or release train.
4. Separate optical and copper breakout choices in the quote
When asking for price and stock, state whether the requirement is QSFP-4X10G-AOC10M active optical or QSFP-4X10G-AC10M active copper. The names are close, but the cable construction and physical routing values are different.

Helps installers plan which side of the rack should receive the QSFP connector |
|
Platform support |
Host device, port group, line card, and software release |
