SFP+ Twinax Cable CBO 45W2399-BL 1 m Male-to-Male 10 Gbit/s

Direct-attach SFP+ Twinax Cable CBO 45W2399-BL, 1 m Male-to-Male, is a factory-terminated copper interconnect designed for short-range 10 Gbit/s links between devices with SFP+ ports. The 1-metre cable provides a compact, energy-efficient connection ideal for top-of-rack switches, servers and network interface cards where low latency and reliable signal integrity are required. The Male-to-Male connectors allow plug-and-play installation without additional transceivers.

Advantages

The cable delivers 10 Gbit/s throughput with low power consumption compared to optical transceivers, offering a cost-effective solution for short-distance links. Its factory-terminated construction ensures consistent electrical characteristics and reduced installation errors. The compact twinax design minimizes rack clutter and supports direct connections between SFP+ ports for predictable latency and stable performance in data-center and enterprise environments.

Suitable for

• Short-range connections between switches and routers in racks
• Server to switch connections in data centres
• High-density top-of-rack interconnects
• Direct-attached links for network interface cards (NICs)

Key specifications

• Connector type: SFP+ Male-to-Male direct-attach
• Data rate: up to 10 Gbit/s
• Cable length: 1 metre
• Cable type: twinax copper, factory-terminated
• Typical use: short-reach, rack-level interconnects
• Latency: low, suitable for latency-sensitive applications

How to use

Install the cable by inserting each SFP+ male connector into the SFP+ port of the two devices to be linked, ensuring secure seating and latch engagement. No additional transceivers or configuration should be required for standard SFP+ ports that accept direct-attach copper cables. Verify link status on both devices and confirm negotiated speed of 10 Gbit/s. For removal, release the connector latches and gently withdraw the cable to avoid stress on the connectors or ports.

Recommendations

Use this 1 m twinax cable within rack or cabinet environments where short, fixed-length connections are needed. Avoid sharp bends and excessive pulling; maintain the minimum bend radius specified by the manufacturer. Keep the connectors clean and protected when not in use to preserve contact quality and ensure consistent 10 Gbit/s performance.
