SFP+ Cable BlueOptics SFP-10G-CU-1M-NE-BL 1m Male/Male

The BlueOptics SFP-10G-CU-1M-NE-BL is a 1 metre SFP+ direct attach cable (DAC) with SFP+ male connectors on both ends, designed for short-distance 10G connections in racks and adjacent rack systems. This passive twinax copper cable supports 10GBase-CR electrical signalling and complies with MSA form-factor specifications, providing a low-latency, low-power link for switches, routers, servers and storage systems that accept SFP+ DAC modules.

Advantages

This 1m SFP+ cable offers a compact and economical connection for high-speed server and network interconnects, with typical passive DAC benefits: minimal power consumption, low latency and simple installation. Manufactured from high-quality components and tested for interoperability, the cable is suitable for densely populated rack environments and short-reach links where optical transceivers are unnecessary. The passive design eliminates active circuitry in the cable, reducing points of failure and lowering operating costs.

Suitable for

• Short-range 10 Gbps connections between switches in the same rack or adjacent racks
• Server-to-switch and server-to-storage links supporting SFP+ DAC
• Data centre top-of-rack (ToR) and aggregation layer cabling
• Environments where low power consumption and low latency are prioritised

Key specifications

• Form factor: SFP+ to SFP+ (male/male)
• Length: 1 metre
• Type: Passive twinax copper direct attach cable (DAC)
• Data rate: Up to 10 Gbps
• Standard support: 10GBase-CR electrical signalling; MSA-compliant connector design
• Conductor gauge: 30 AWG twinax
• Typical use case: Short-reach electrical interconnects in racks and adjacent racks

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your networking device until the latch engages. Ensure both devices support passive SFP+ DACs and the 10GBase-CR protocol. No additional power or configuration is required for the cable itself; network settings such as link speed, duplex and interface activation are handled on the attached devices. When removing the cable, release the connector latch and pull the cable straight out to avoid damaging the port.

Recommendations

Confirm compatibility with your switch, router or storage hardware before deployment and, where possible, test a sample to verify link negotiation and performance. Use this cable for short-distance 10G links; for longer distances or optical isolation requirements, consider SFP+ optical transceivers and fibre optics instead.
