Cisco 10GBASE-CU SFP+ Passive Twinax Direct Attach Cable, 3 m

Passive twinax copper is the construction of the Cisco 10GBASE-CU SFP+ Passive Twinax Direct Attach Cable, part number SFP-H10GB-CU3M. It is 3 m long, with an SFP+ connector on each end, and it runs at 10GbE.

A direct attach cable is the simplest way to link two 10GbE devices that sit close together. There are no separate transceivers to buy, no fiber to clean and no optics to manage. A typical use is connecting a server adapter to a top-of-rack switch in the same or neighboring rack.

Three meters leaves some room for routing, but the real cable path is longer than the distance between ports, so measure the route before ordering. If the run is longer, step up to an active optical cable or a transceiver and fiber pair.

Check host support. Some switches and adapters accept only specific direct attach cables, and the documentation lists what each supports.

Because the cable is fixed, if one end fails, you replace the whole assembly instead of a module.

The SFP-H10GB-CU3M is offered in new, refurbished and used condition. New and refurbished cables carry 1 year or 3 years of warranty, and used cables carry 90 days. Send your quantity and platforms for pricing.
