QSFP-H40G-AOC15M Description

The QSFP-H40G-AOC15M is a Cisco 40GBASE-AOC QSFP+ to QSFP+ active optical cable for 40G links of up to 15 meters between racks or across a cabinet row. The cable has a 3.5 mm QSFP-end diameter, a 60 mm bend radius, a 115 mm face plate distance, a PVC jacket and a black pull tab, and each end draws 1.5W. The thin optical construction takes less room in cable managers than copper and has no EMI concerns.

Application Scenarios

Cabinet-To-Cabinet Overhead Run

Two cabinets on opposite sides of an aisle can be joined at 40G through overhead trays when the measured route is longer than 10 meters, with the 60 mm bend radius setting the tightest turn along the way.

Full Cable Managers In Dense Rows

Dense rack rows with full cable managers carry 40G QSFP+ links on the 3.5 mm optical cable, whose thin profile leaves more space for exhaust air than a 9 mm copper cable.

QSFP-H40G-AOC15M is the 15-meter cable of the QSFP-H40G-AOC group, which differs from QSFP-H40G-AOC10M and QSFP-H40G-AOC20M only in length and pull tab color (black here, red at 10 meters, green at 20 meters), with the same 3.5 mm diameter, 60 mm bend radius and 115 mm face plate distance. Paths of 10 meters or less fit QSFP-H40G-AOC10M, and paths longer than 15 meters up to 20 meters fit QSFP-H40G-AOC20M; Cisco lists the same cable in 25 and 30 meters for longer routes. Where 10 meters is enough and copper is acceptable, QSFP-H40G-ACU10M is the active copper alternative, at 9 mm thick against 3.5 mm here.

Ordering Checklist

  • Host support: Confirm the 40G QSFP port on the host and the far-end ports for QSFP-H40G-AOC15M appear in Cisco’s Optics-to-Device Compatibility Matrix (tmgmatrix.cisco.com). Platform support is listed in that matrix, not in the cable data sheet.
  • Platforms with SFP+ ports only: Add the CVR-4SFP10G-QSFP reverse adapter, which lists QSFP-H40G-AOC15M as a supported QSFP+ module; CVR-TRAY-8 or CVR-BRKT-1 holds the adapters. A cable with QSFP+ ends has no port to plug into on a platform that offers only SFP+ ports.

Questions & Answers

  • What is the reach of QSFP-H40G-AOC15M?

    QSFP-H40G-AOC15M reaches 15 meters at 40 Gigabit Ethernet. The assembly is a fixed length with QSFP+ connectors at both ends, so the measured route between the two ports must fit within 15 meters.
  • What operating temperature does QSFP-H40G-AOC15M support?

    QSFP-H40G-AOC15M operates from 0 to 70°C. The cable is not rated below 0°C and each end draws 1.5W, so use it in temperature-controlled racks and rooms, and keep it out of unheated or outdoor spaces.
  • How long is QSFP-H40G-AOC15M in feet?

    QSFP-H40G-AOC15M is 49.2 ft long. Cisco's N7K hardware installation guide converts the 15 m length this way for the AOC family. Measure the routed path in feet if your cable tray plans are in imperial units, and add the bend allowance at each end.
  • Is QSFP-H40G-AOC15M listed individually in the Nexus 7000 installation guide?

    Yes, QSFP-H40G-AOC15M is listed individually among the supported F3-Series products in the Cisco N7K hardware installation guide. The guide also lists the AOC family under a general QSFP-H40G-AOCxM entry. Check the matrix for your line card before you order.
  • Can QSFP-H40G-AOC15M be used in a 4SQRA reverse adapter?

    Yes, Cisco's 4SQRA reverse adapter guide lists QSFP-H40G-AOC15M in its Table 1 of QSFP+ modules that fit the adapter, next to the other AOC lengths of 1M, 2M, 3M, 5M, 7M and 10M. This gives a route to hosts that offer only SFP+ ports. The AOC itself remains a fixed 15 m assembly.
  • What is the tightest bend QSFP-H40G-AOC15M allows at the QSFP end?

    The QSFP end has a 60 mm bend radius and a 115 mm face plate distance. Leave at least that much clearance in front of the port. The cable diameter at the QSFP end is 3.5 mm, which helps in crowded cable managers.
