About the SFP-H10GB-CU3M
The Cisco SFP-H10GB-CU3M direct attach copper cable provides cost effective point to point 10 Gigabit Ethernet connectivity inside network equipment enclosures. It uses an integrated passive twinaxial cable assembly terminating in permanent SFP+ module connectors at both ends. It operates with negligible latency and minimal electrical power draw compared to optical transceivers.
Compatibility
Compatible with Cisco Nexus 9000, 7000, 5000, 3000 Series data center switches, Cisco Catalyst 9000 Series enterprise switches, and major Cisco UCS server network interface adapters. It supports 10GbE host connections to server NICs and top of rack switch ports within adjacent rack positions.
How to identify a genuine unit
Features black twinaxial shielded copper cabling with permanently affixed zinc die-cast SFP+ connector heads. Each connector plug has a pull-release tab and a factory printed label displaying assembly number 37-0961-01, part designation SFP-H10GB-CU3M, and individual serialized identification codes.
Buying used
Inspect the copper cable sheath for kinks, pinching, or abrasions along its entire length. Check the electrical gold finger contacts on each SFP+ plug head for oxidation or mechanical damage, and connect both ends into live switch ports to verify link state and absence of cyclical redundancy check errors.
