Cisco Compatible SFP+ Direct Attach

The StarTech SFPCMM5M is a 5 metre passive Twinax copper cable with SFP+ connectors on both ends. It is designed, programmed and tested for 100 percent compatibility with Cisco switches and routers including Firepower and ASR920 series. The cable complies with MSA industry standards and is hot-swappable.

Sustained Load Behaviour

As a passive direct attach cable it draws very little power and generates minimal heat during continuous 10 Gbps operation. The 24 AWG conductors and 100 Ohm impedance maintain signal integrity over the full 16.4 foot length without active signal conditioning. This makes it suitable for permanent rack-to-rack or switch-to-server links.

Deciding Specification

The single specification that determines fit is the 5 metre reach at 10 Gbps over passive copper. If your topology requires a longer run or an active optical link this cable will not meet the distance requirement. Buyers who need more than 5 metres between SFP+ ports must choose a different medium.

Questions about this item

Does the 24 AWG passive twinax cable draw extra power or generate heat when run continuously at 10 Gbps?

No, the passive copper design requires no external power and adds negligible heat during all-day 10 Gbps operation.

Which switch ports must I already have to plug this cable in directly?

You need two SFP+ ports that accept uncoded or Cisco-coded modules; the cable is hot-swappable in compatible Cisco, Ubiquiti, D-Link, Netgear, Supermicro and TP-Link switches.

Will the 100 Ohm impedance and 5 m length work reliably with my older 10GBASE-CX4 or SFP+ gear?

Yes, the MSA-compliant 100 Ohm twinax assembly is designed for 10 GbE SFP+ links up to 5 m and interoperates with legacy SFP+ equipment that follows the same standard.
