SFP+ Direct-Attach Cable CBO 74752-2051-BL 0.5 m Male-to-Male 10 Gbit/s

The BlueOptics SFP+ Direct-Attach Cable 0.5 m (model 74752-2051-BL) is a 50 cm male-to-male twinax assembly designed for short-range 10 Gbit/s connections. It provides a cost-effective, low-power alternative to optical transceivers for direct links between SFP+ ports on switches, network interface cards (NICs) and servers. The compact twinax design minimizes latency and signal loss over short distances, making it suitable for dense rack and data center topologies.

Advantages

This 0.5 m direct-attach cable supports 10 Gbit/s throughput while offering lower power consumption and reduced component cost compared with optical modules and separate transceivers. Its plug-and-play SFP+ connectors require no additional configuration and deliver low latency for high-throughput applications. The short, robust twinax construction reduces crosstalk and simplifies cable management in rack environments.

Suitable for

• Short-range connections between SFP+ ports on switches
• Direct links from servers to top-of-rack or leaf switches
• Interconnects between NICs and adjacent network appliances
• Dense in-rack cabling in data centers and server rooms

Key specifications

• Data rate: 10 Gbit/s full-duplex
• Connector type: SFP+ male-to-male twinax
• Cable length: 0.5 m (50 cm)
• Cable type: Passive twinax direct-attach
• Typical use range: short-reach, within racks or between adjacent racks
• Latency: low, suited for latency-sensitive links

How to use

Insert the SFP+ connectors into compatible SFP+ ports on your networking devices until they latch. Ensure both ends are seated in SFP+ cages and that ports are powered off or follow hot-plug procedures recommended by the hardware vendor. After connection, verify link status and negotiated speed through the switch or server management interface. For stable operation, avoid sharp bends and excessive strain on the cable assembly.

Recommendations

Use this 0.5 m direct-attach cable where short, high-bandwidth links are required and optical transceivers are unnecessary. Choose passive twinax for short, cost-sensitive links and consider active or optical options for longer distances. Maintain proper bend radius and secure routing in racks to preserve signal integrity and connector reliability.
