BlueOptics AP785A-BL InfiniBand/fibre optic cable 5 m SFP+ Male/Male

The BlueOptics AP785A-BL InfiniBand/fibre optic cable is a 5 m twinax direct attach cable with SFP+ male connectors on both ends. Designed for short-distance, high-speed links in racks and adjacent racks, this cable supports 10 Gigabit-class transmission over a reliable copper twinax assembly that complies with common SFP+ and MSA requirements. It is suitable for connecting switches, routers, storage systems and other devices that accept SFP+ direct attach connections.

Advantages

This 5 m SFP+ male-to-male cable provides a low-latency, low-power physical connection for short-range high-bandwidth links. As a passive direct attach twinax solution, it does not require additional transceivers or external power, which simplifies installation and reduces ongoing power consumption. The construction follows common industry mechanical and electrical specifications for SFP+ DACs to ensure compatibility with equipment that supports the original AP785A form factor and signaling.

Suitable for

• Interconnects between rack-mounted switches and adjacent racks
• Server-to-switch and storage-to-switch direct links
• InfiniBand and other 10G-class short-reach high-speed connections
• Data center top-of-rack and aggregation layer links

Key specifications

• Cable type: passive twinax direct attach (SFP+ to SFP+)
• Length: 5 meters
• Connector gender: SFP+ male on both ends
• Supported link class: 10 Gigabit-class short-reach connections (InfiniBand/Fibre Channel/Ethernet/FCoE as applicable)
• Conductor gauge: 24 AWG construction typical for direct attach twinax assemblies
• MSA-compliant SFP+ form factor and electrical interface

How to use

Install the BlueOptics AP785A-BL by inserting each SFP+ connector into the SFP+ port of the two devices to be linked. Ensure both devices support passive direct attach twinax SFP+ cables and that ports are powered according to the device vendor’s specifications. No external power or transceiver modules are required. After physical connection, verify link status in the network equipment management interface and, if needed, configure speed and protocol settings according to your network design.

Recommendations

Use this cable for short-distance, high-throughput links within racks or between adjacent racks. Verify vendor compatibility lists for passive SFP+ twinax assemblies before deployment and avoid routing the cable near strong electromagnetic interference sources or sharp bends; maintain recommended bend radius. For long-term reliability, inspect connectors for contamination and ensure secure seating in SFP+ ports during installation and maintenance.
