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

Overview

The Black Box SFP-H10GB-CU1M5-BB is a 1.5 meter (4.9 foot) SFP+ direct attach copper cable designed to transfer data at speeds up to 10 gigabits per second between two network ports. It is preprogrammed for seamless compatibility with Cisco SFP-H10GB-CU ports, allowing straightforward installation in Cisco switches, routers, or servers without additional configuration. The cable also adheres to open SFP+ MSA and SFF-8431 standards, ensuring broad compatibility with equipment from other manufacturers.

This passive copper cable consumes only 0.0003 watts, minimizing power use and heat output. Its direct copper connection avoids optical conversion, resulting in very low latency, which is essential for time-sensitive data traffic and high-performance storage access. The cable’s hot-swappable design enables live installation or replacement without powering down devices, and its CL2 rated PVC jacket supports installation in environments requiring Class 2 cables. It operates reliably within a temperature range of 0 to 70 °C, suitable for typical data center and wiring closet conditions.

Connectivity and compatibility

This cable is designed to connect two SFP+ ports directly, making it a practical choice for short-range, high-speed links within racks or between adjacent network devices. Its programming for Cisco hardware ensures plug-and-play operation in Cisco environments, while adherence to open standards allows use with other vendors’ switches and servers that support SFP+ modules. The direct attach copper design eliminates the need for optical transceivers, simplifying setup and reducing overall cost.

Ideal uses and environments

The Black Box SFP-H10GB-CU1M5-BB fits well in data centers, enterprise networks, and cloud facilities where reliable, low-latency 10 Gbps connections are needed over short distances. It is especially useful for top-of-rack switch uplinks, server interconnects, and temporary lab setups where quick changes and hot swapping are common. Its low power draw and heat output make it suitable for dense rack environments where thermal management is critical.
