SFP-H10GB-CU1M Description

The SFP-H10GB-CU1M is a Cisco 10GBASE-CU passive Twinax SFP+ cable assembly for 10 Gigabit Ethernet links of 1 m between SFP+ ports. The cable has an SFP+ connector at each end, draws up to 0.1W, operates from 0 to 70°C and has a beige bail latch. The cable is a passive assembly with a fixed 1 m length, and support on a given host port is set by the Cisco Transceiver Module Group Compatibility Matrix.

Application Scenarios

Same-Rack Switch Links

Inside one rack, the 1 m passive cable connects two neighboring switches or a switch and a server through their SFP+ ports.

Catalyst 9200L Uplink Cabling

A Catalyst 9200L Multigigabit switch with 10G uplinks can link to an adjacent switch in the same rack through the cable.

SFP-H10GB-CU1M and SFP-H10GB-CU1-5M are both passive 30 AWG Twinax cables at 0.1W, but SFP-H10GB-CU1M is 1 meter with a beige bail latch and SFP-H10GB-CU1-5M is 1.5 meters with a black one, so routes longer than 1 meter step up to SFP-H10GB-CU1-5M. Routes of 2 meters use SFP-H10GB-CU2M, which has a brown latch. Routes beyond 2 meters, up to 7 meters, need the active SFP-H10GB-ACU7M, which draws 1W instead of 0.1W and has a blue latch. All four use 30 AWG construction and the commercial temperature class.

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.

Questions & Answers

  • Which NX-OS release does SFP-H10GB-CU1M need on N7K-M132XP-12L?

    SFP-H10GB-CU1M needs NX-OS 8.1(1) on N7K-M132XP-12L and N7K-M224XP-23L, per the Nexus hardware installation guide. It is listed without a release note on N7K-M108X2-12L and N7K-M348XP-25L, and it is not listed for N7K-M132XP-12. Upgrade the software before using the cable on the first two cards.
  • What version identifier must SFP-H10GB-CU1M carry before a Catalyst host accepts it?

    The CX1 version identifier must be 2 or higher, per the Catalyst hardware installation guide cable section. Check the identifier on the SFP-H10GB-CU1M assembly before deployment, since an older version is not accepted. The guide lists this cable as a 1 m, 30 AWG twinax assembly of 3 ft.
  • How many feet is the 1 m length of SFP-H10GB-CU1M?

    The 1 m length of SFP-H10GB-CU1M is 3.3 ft, per the Nexus hardware installation guide, for a passive 30 AWG twinax assembly. The same guide lists the passive family at 1, 3 and 5 m. The length is fixed, so measure the rack path in feet if needed and leave slack for the bend radius.
  • Which Nexus F-series line cards list SFP-H10GB-CU1M?

    SFP-H10GB-CU1M is supported on N7K-F132XP-15, N7K-F248XP-25, N7K-F248XP-25E and N7K-F348XP-25, per the Nexus hardware installation guide, in a row shared with SFP-H10GB-CU3M and SFP-H10GB-CU5M. No NX-OS 8.1(1) note applies on those four cards, so the cable can be installed there without a release check.
