SFP-H10GB-ACU10M Description

The SFP-H10GB-ACU10M is a Cisco 10GBASE-CU active Twinax SFP+ cable assembly for 10 Gigabit Ethernet links of 10 m between SFP+ ports. The cable has an SFP+ connector at each end, draws up to 1W, operates from 0 to 70°C and has a red bail latch. The cable is an active copper assembly, and support on a given host port is set by the Cisco Transceiver Module Group Compatibility Matrix.

Application Scenarios

Row-To-Row Server Links

In a data center, the 10 m active copper cable joins a top-of-rack switch to a server or switch in the next row without separate optics and fiber.

UCS Fabric Interconnect Cabling

A Cisco UCS 6300 Series fabric interconnect uses the cable as its 10 m active 10GBASE-CU SFP+ link to neighboring switches and servers.

SFP-H10GB-ACU10M is the 10-meter active Twinax copper cable in this group, while SFP-H10GB-ACU7M is the same active copper type at 7 meters, so runs that fit within 7 meters can use SFP-H10GB-ACU7M. Runs of 5 meters or less can use the passive SFP-H10GB-CU5M, which draws 0.1W against 1W for the active cables. Where an optical cable is required at the same 10 meters, SFP-10G-AOC10M is an active optical cable assembly rather than Twinax copper. All four are SFP+ to SFP+ 10 Gigabit cables in the commercial temperature class, and SFP-H10GB-ACU10M and SFP-10G-AOC10M both use a red bail latch.

Ordering Checklist

  • Catalyst 9200L hosts: Confirm the host is a Catalyst 9200L Multigigabit model (C9200L-24PXG-2Y, C9200L-24PXG-4X, C9200L-48PXG-2Y or C9200L-48PXG-4X) using its 10G uplinks. A cable that fits an SFP+ cage can still be unsupported; Cisco’s TMG matrix is the final reference for each host.

    Our receiving department flagged it as genuine immediately. Professional packaging. Wish the lead time was a bit shorter, but product quality made up for it.

Questions & Answers

  • How long is SFP-H10GB-ACU10M in feet and what conductor gauge does it use?

    SFP-H10GB-ACU10M is 10 m (32.5 ft) long and uses 28 AWG conductors. The active Twinax assembly has an SFP+ connector at each end, so it is a single fixed-length piece between two SFP+ ports.
  • What are the storage temperature, size and weight of the SFP-H10GB-ACU10M connectors?

    SFP-H10GB-ACU10M can be stored from -40 to 85°C, beyond its 0 to 70°C operating range. Each SFP+ connector measures 8.5 x 13.4 x 56.5 mm and weighs 75 grams or less, which is the standard SFP+ cage footprint.
  • Does SFP-H10GB-ACU10M need separate optics at either end?

    No. SFP-H10GB-ACU10M is a complete active copper assembly with an SFP+ connector at each end, so no transceivers or fiber are added. It joins two SFP+ ports directly over 10 m.
  • What power does SFP-H10GB-ACU10M draw and what operating range does it have?

    SFP-H10GB-ACU10M draws up to 1W and operates from 0 to 70°C in the commercial temperature class. Because the assembly is active, it takes power from the SFP+ port at each end, which belongs in the port power plan for dense racks.
