QSFP-100G-AOC7M Description

The QSFP-100G-AOC7M is a Cisco 100G QSFP active optical cable for rack-to-rack links of up to 7 meters between QSFP ports. The assembly draws 3.5W per end, measures 3.5 mm in cable diameter with a 30 mm bend radius, and has a blue pull tab. Both ends are fixed QSFP connectors on one cable, and the commercial operating range is 0 to 70°C.

Application Scenarios

Cross-Row 100G Interconnect

A server hall can run the cable across a hot aisle or between neighboring rows, linking a 100G QSFP port on one switch to a port on another switch up to 7 meters away.

Thin Cabling In Overhead Trays

When 100G links share overhead trays with many other runs, the optical cable’s 3.5 mm diameter takes far less tray space than a passive copper cable of similar length would.

QSFP-100G-AOC7M and QSFP-100G-AOC10M are both 100GBASE QSFP active optical cables at 3.5W per end with a 3.5 mm diameter and 30 mm bend radius, so they differ only in length (7 m against 10 m) and pull tab color (blue against red). A path longer than 7 m needs QSFP-100G-AOC10M. Passive copper tops out at 5 m in this family, so a route between 5 m and 7 m cannot use QSFP-100G-CU5M or QSFP-100G-CU3M; those two copper cables draw 1.5W per end but are thicker, at 7 mm and 9 mm with 50 mm and 70 mm bend radius, which suits short runs where cable bulk is not a concern.

Ordering Checklist

  • Host support: Confirm the target Cisco switch or router and its QSFP28 port are listed for QSFP-100G-AOC7M in the Cisco 100 Gigabit Ethernet Transceiver Modules Compatibility Matrix. A cable that fits the cage can still be unsupported on a given host.

Questions & Answers

  • What is QSFP-100G-AOC7M used for?

    QSFP-100G-AOC7M is a Cisco 100GBASE QSFP active optical cable for short-distance 100G Ethernet links between QSFP-to-QSFP ports in high-density rack and cross-rack cabling.
  • How long is QSFP-100G-AOC7M?

    QSFP-100G-AOC7M is 7 meters long and consumes 3.5W per end. Cisco identifies this cable length with a Blue pull tab.
  • Which Cisco ports are compatible with QSFP-100G-AOC7M?

    QSFP-100G-AOC7M connects compatible Cisco 100G QSFP ports through a fixed QSFP-to-QSFP cable assembly. The 7-meter active optical cable carries 100 Gigabit Ethernet between the two host ports.
  • How does QSFP-100G-AOC7M differ from QSFP-100G-CU3M?

    QSFP-100G-AOC7M is the optical direct-attach choice in this comparison; QSFP-100G-CU3M and QSFP-100G-CU5M are passive copper 100GBASE-CR4 cables with shorter lengths.
  • Can QSFP-100G-AOC7M operate from 0 to 70 degrees C?

    Yes, QSFP-100G-AOC7M has a commercial operating range of 0 to 70 degrees C. It remains a fixed QSFP-to-QSFP active optical assembly.
