SFP+ Direct Attach Cable BlueOptics 10GBASE-CR 1 m (model 10304-BL)

BlueOptics SFP+ Direct Attach Cable 10GBASE-CR 1 m (model 10304-BL) is a 1‑metre passive copper twinax cable designed for short-range 10 Gigabit Ethernet links. Intended for use with SFP+ ports, the cable supports 10 Gbps throughput and is optimized for low-latency server-to-switch and switch-to-switch connections within data centres and network racks. Its compact, flexible construction simplifies installation in dense environments while maintaining reliable electrical performance for short-reach interconnects.

Advantages

This SFP+ direct attach cable delivers native 10 Gbps performance with minimal latency and low power consumption compared with active optical options. Its passive twinax design reduces cost for short-distance links and provides consistent signal integrity over the specified 1 metre length. The integrated SFP+ connector housings comply with standard module form factors to ensure compatibility with SFP+ ports from various vendors when passive copper cabling is supported.

Suitable for

• Server-to-top-of-rack switch connections in data centres
• Switch-to-switch links in the same rack or adjacent racks
• Short-reach aggregation and access layer interconnects
• High-density network deployments requiring cost-effective 10G connections

Key specifications

• Connector type: SFP+ form-factor direct attach (twinax)
• Standard supported: 10GBASE-CR (10 Gigabit Ethernet over copper)
• Data rate: 10 Gbps
• Length: 1 metre
• Cable type: Passive copper twinax
• Latency: low, suitable for latency-sensitive short links
• Power consumption: passive (no external power required)

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the module latches. Ensure devices are powered off or ports are safely hot-pluggable according to the equipment vendor’s guidance. Verify link status and network configuration on both endpoints after connection. For best results, route the cable to avoid sharp bends and excessive strain on the connectors during and after installation.

Usage recommendations

Use this 1 m passive SFP+ twinax cable for short, direct 10G links inside racks or between adjacent racks. Confirm that both network devices support passive SFP+ direct attach cables and that the 1 metre length matches your planned cable runs. Avoid installing the cable in environments with electromagnetic interference or where longer runs are required; in such cases, consider active copper or optical alternatives.
