SFP+ Transceiver CBO SFP-10G-C5M 10Gbps, 5 m Direct Attach Copper for 10G Ethernet

The CBO SFP-10G-C5M is a passive SFP+ direct attach copper (DAC) cable assembly that provides a 10Gbps electrical connection over a fixed 5-metre twinax cable. Designed for 10G Ethernet and compatible with standard SFP+ ports, the cable enables cost-effective short-reach links with predictable latency and lower power consumption compared with optical transceivers. It is intended for use in data centres, server rooms and network racks where reliable, short-distance connectivity is required between servers, switches and storage devices.

Advantages

The passive twinax design delivers a reliable 10Gbps physical link with minimal configuration, eliminating the need for separate optical transceivers and fiber patch cords. The fixed 5 m length simplifies rack planning and reduces clutter while offering lower latency and reduced power draw versus optical alternatives. Compatibility with standard SFP+ ports ensures plug-and-play operation in many switches and servers that support passive DACs.

Suitable for

• Server-to-switch connections inside a rack or between adjacent racks
• Switch-to-switch short-reach uplinks in data centre topologies
• Direct-attached storage links and appliance interconnects
• Environments requiring predictable latency and reduced power consumption

Key specifications

• Data rate: 10 Gbps
• Interface: SFP+ electrical twinax connectors
• Cable type: Passive twinax copper
• Fixed length: 5 metres
• Reach: Short-reach, suitable for in-rack and adjacent-rack connections
• Latency: Low, electrical transmission
• Power: Passive design with reduced power consumption compared to optical modules

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the devices to be connected, ensuring the latch engages. No additional configuration is typically required at the hardware level; verify link status in your switch or host operating system and confirm speed is negotiated at 10Gbps. Handle the cable by the connector housings when inserting or removing, and avoid sharp bends near the cable ends to maintain mechanical integrity.

Usage recommendations

Use this 5 m passive DAC for short-distance links where electrical connectivity and low latency are priorities. Check device compatibility lists or vendor documentation for confirmed support of passive SFP+ modules before deployment. Keep the cable within recommended bend radius and avoid placing it near sources of strong electromagnetic interference for best signal integrity.
