QSFP-H40G-AOC2M Description

The QSFP-H40G-AOC2M is a Cisco 40GBase-AOC QSFP direct-attach active optical cable for 40 Gigabit Ethernet links between QSFP ports in the same rack or in adjacent racks. The 2 m assembly has a brown pull tab, a 3.5 mm QSFP-end cable diameter, a 60 mm bend radius and a 115 mm face plate distance, and it draws 1.5 W at each end across a 0 to 70 C operating range. Host support depends on the platform and software release listed in the Cisco 40-Gigabit Ethernet Transceiver Modules Compatibility Matrix.

Application Scenarios

In-Rack Links Between Switches

Inside a single data center rack, the cable joins two QSFP ports on neighboring switches or a switch and a fabric extender, and its 3.5 mm optical jacket leaves more room in the cable manager than a thick copper cable.

Short Runs Beside The Top Of Rack

Where a top-of-rack switch uplinks to an aggregation switch one rack over, the 2 m length reaches across the gap and the 60 mm bend radius lets it turn into the cable tray without strain.

QSFP-H40G-AOC2M is the 2 m member of this 40GBase-AOC group: QSFP-H40G-AOC1M and QSFP-H40G-AOC3M share its 3.5 mm QSFP-end diameter, 60 mm bend radius and 115 mm face plate distance, so only fixed length and pull tab color differ (beige at 1 m, brown at 2 m, orange at 3 m). A path of 1 m or less fits QSFP-H40G-AOC1M, and a path between 2 m and 3 m needs QSFP-H40G-AOC3M, because each cable has one fixed length. Where one QSFP port must feed four 10G SFP+ ports, a breakout cable such as QSFP-4X10G-AOC10M replaces this straight QSFP-to-QSFP cable.

Ordering Checklist

  • Host support: Confirm the target Cisco switch or line card and its QSFP+ port are listed for QSFP-H40G-AOC2M in the Cisco Optics-to-Device Compatibility Matrix. A cable that fits the QSFP cage can still be unsupported on a given host.

Questions & Answers

  • What is the reach of QSFP-H40G-AOC2M?

    QSFP-H40G-AOC2M reaches 2 meters at 40 Gigabit Ethernet. The length is fixed in the assembly, so the two QSFP ports must sit in the same rack or in adjacent racks with a route of 2 meters or less.
  • What operating temperature does QSFP-H40G-AOC2M support?

    QSFP-H40G-AOC2M 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 cabinets.
  • How long is QSFP-H40G-AOC2M in feet?

    QSFP-H40G-AOC2M measures 6.6 ft. Cisco's QSFP+ cable installation guide lists the active optical QSFP+ cable family in 1, 2, 3, 5, 7, 10 and 15 m lengths, so this 2 m cable sits near the short end.
  • What storage temperature range applies to QSFP-H40G-AOC2M?

    QSFP-H40G-AOC2M can be stored from -40 to 85 C. The operating range is narrower, so let the cable reach room conditions before the link is brought up after cold or hot storage.
  • What are the connector module dimensions and weight of QSFP-H40G-AOC2M?

    The QSFP connector module of QSFP-H40G-AOC2M measures 13.5 x 18.4 x 72.4 mm at most and weighs 100 g or less. It follows the QSFP+ MSA SFF-8436 form factor, so any compliant QSFP cage takes the connector.
  • Does QSFP-H40G-AOC2M meet RoHS requirements?

    Yes, QSFP-H40G-AOC2M is listed with RoHS 6 compliance. The assembly also has an orange PVC jacket, and the jacket color does not change the compliance listing. The listing covers both connector modules and the cable between them.
