BlueOptics 10G-SFPDA-1M-BL InfiniBand Fibre Optic Cable SFP+ 1m Male/Male

The BlueOptics 10G-SFPDA-1M-BL InfiniBand Fibre Optic Cable SFP+ 1m Male/Male is a 1 meter direct-attach cable with SFP+ connectors designed for short-range high-speed links. It implements a 10G electrical interface suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 10 Gbit/s. The cable is intended for connecting switches, routers, storage systems and servers in rack and adjacent-rack setups where a passive direct attach twinax solution is appropriate.

Advantages

This SFP+ direct attach cable provides a low-latency, low-power connection for short-distance links and requires no additional transceivers or active optics. Built to MSA-compatible mechanical and electrical specifications, it is tested for interoperability with major hardware platforms that support SFP+ passive DACs. The passive twinax design reduces complexity and power consumption while offering a cost-effective alternative to separate transceivers and fiber assemblies.

Suitable for

• Interconnects between switches and routers inside racks
• Server-to-switch connections in data centers
• Short-distance storage and SAN links using 10G protocols
• High-performance computing node interconnects

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 1 meter
• Data rate: up to 10 Gbit/s
• Cable type: passive twinax copper (direct attach cable)
• Wire gauge: 30 AWG
• Standards compatibility: 10GBase-CR, SFP+ MSA electrical interface

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be linked until the latch engages. Ensure both devices are configured to accept passive DACs and that firmware or vendor settings do not block third‑party cables. No external power or optical transceivers are required; the connected hardware handles signaling and link negotiation. For best results, route the cable without sharp bends and avoid mechanical stress at the connector ends.

Recommendations

Use this cable for short-range connections within racks or between adjacent racks. Verify hardware compatibility with passive SFP+ direct attach cables and ensure airflow is not obstructed around ports. Avoid exceeding the published bend radius and protect the connectors when inserting or removing the cable.
