Black Box 4.9ft SFP+ 10-Gbps Direct Attach Cable (Black)

The Black Box SFP-H10GB-CU1M5-BB is a 1.5 meter, 4.9 foot SFP+ direct attach copper cable that moves data at up to 10 gigabits per second between two network ports. It arrives programmed for Cisco SFP-H10GB-CU compatibility, so it snaps straight into Cisco switches, routers, or servers without manual configuration, yet it also follows open SFP+ MSA and SFF-8431 guidelines for use with equipment from other vendors.

The passive copper design draws only 0.0003 watts, which keeps power consumption and heat generation to an absolute minimum. Because there is no optical conversion, latency remains exceptionally low, making the link well suited for time-sensitive traffic or high-performance storage access. The cable is hot swappable, letting you add or replace connections without powering down devices, and the CL2 rated PVC jacket allows installation in spaces where a Class 2 cable is required. An operating range of 0 to 70 °C covers typical data center and wiring closet conditions.

Administrators choose this model for short point-to-point links inside racks, top of rack switch uplinks, or temporary lab setups where quick changes are common. Its cost effective build, reliable performance, and vendor versatility make it a practical choice for enterprise networks, cloud facilities, and test environments alike.
