This Add-On Computer Cisco Compatible 10GBase-CU SFP+ to SFP+ Direct Attach Cable delivers a reliable high-speed interconnect solution for data center and enterprise networking environments. Designed as a passive copper cable assembly, it eliminates the need for separate transceivers, offering a low-latency, low-power connection between two SFP+ ports. The cable supports 10 Gigabit Ethernet data rates over a three-meter length, making it suitable for rack-to-rack or rack-internal linkages. Its construction uses twinaxial copper conductors with a durable PVC jacket, ensuring consistent signal integrity and resistance to electromagnetic interference. The connectors are molded with a robust strain-relief boot to protect the SFP+ latch mechanisms during installation and removal.

The direct attach cable architecture reduces overall system cost and complexity by combining the optical transceiver function with the cable itself. Each end is fitted with a standard SFP+ plug that meets the Small Form-Factor Pluggable Plus multisource agreement requirements. The passive design requires no external power, contributing to lower energy consumption in high-density deployments. Shielding is applied throughout the cable length to minimize crosstalk and maintain stable transmission rates up to the full 10Gbps line speed. The 30 AWG conductors are paired with a shielded drain wire, and the overall assembly undergoes electrical testing to verify impedance matching and return loss specifications.

In terms of performance, this cable delivers consistent throughput with negligible packet loss under varying temperature conditions. It operates within a wide ambient temperature range, making it adaptable to different server room environments. The copper medium provides inherently lower latency compared to optical solutions, which is beneficial for applications sensitive to transmission delay, such as financial trading or real-time data processing. The three-meter length offers flexibility for connecting devices within a single rack or across adjacent racks without excessive cable slack. The Add-On Computer brand focuses on compatibility, ensuring the cable functions correctly with Cisco switches, routers, and network interface cards that utilize the SFP+ form factor.

Durability is addressed through a double-braided shielding layer and a snag-resistant connector design. The cable can withstand repeated bending and flexing without degradation in performance, thanks to the stranded conductor construction. The latch mechanism on each SFP+ connector is reinforced to prevent accidental disconnection, and the overall assembly meets or exceeds industry standards for mechanical reliability. This direct attach cable is a pragmatic choice for network administrators seeking to minimize points of failure by eliminating separate transceiver modules. Its straightforward plug-and-play nature simplifies installation, requiring no configuration or software activation.

The pricing reflects a competitive value proposition, offering a cost-effective alternative to brand-specific cables while maintaining equivalent performance characteristics. The three-meter length covers many common connectivity requirements, and the passive design ensures long-term reliability without active components that might fail. For organizations scaling their 10G Ethernet infrastructure, this cable provides a balance of functionality and affordability. The absence of separate optics reduces inventory complexity, and the standardized interface ensures broad interoperability with SFP+ ports from major manufacturers.
