InfiniBand/fibre optic cable BlueOptics 53HVN-BL 3 m SFP+ Male/Male

The BlueOptics 53HVN-BL 3 m InfiniBand/fibre optic cable is a direct attach solution with SFP+ connectors on both ends for 10G-class links over short distances. Designed for rack and adjacent-rack connections, this cable supports electrical 10GBase-CR signaling and is compatible with SFP+ ports used in switches, routers and storage systems. The 3 meter length provides a standard reach for data-center top-of-rack or adjacent-rack interconnects while maintaining signal integrity and low latency.

Advantages

This SFP+ Male–Male cable offers reliable transmission at up to 10 Gbit/s with low power consumption and minimal latency. Constructed to industry MSA guidelines, it uses high-quality materials and components to ensure stable performance and long operational life. The passive direct-attach design reduces complexity by avoiding active components in the cable, lowering failure rates and enabling plug-and-play installation in compatible devices.

Suitable for

• 10G Ethernet links in data centers and server rooms
• Switch-to-switch or switch-to-server rack interconnects
• Storage area network (SAN) and Fibre Channel over Ethernet (FCoE) short-reach connections
• InfiniBand and other SFP+-compatible networking equipment that supports passive DAC or direct attach cabling

Key specifications

• Connector type: SFP+ (male) on both ends
• Length: 3.0 meters
• Maximum data rate: up to 10 Gbit/s
• Cable type: direct attach twinax (passive) suitable for short-distance electrical signaling
• Wire gauge: 30 AWG equivalent twinax conductor
• MSA-compliant design for broad compatibility with SFP+ ports

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port until the latch engages. Use the cable for direct connections between SFP+-equipped devices such as switches, routers or servers. Ensure the connected hardware explicitly supports passive direct attach or 10GBase-CR copper twinax cables. Avoid sharp bends and maintain the manufacturer’s recommended bend radius to preserve signal integrity and cable life.

Usage recommendations

For best results, use this 3 m SFP+ cable for short-reach links within racks or to adjacent racks where active optical transceivers are not required. Verify firmware or vendor compatibility if devices enforce vendor checks, and keep connectors clean and free from debris to maintain reliable connections.
