BlueOptics JL296A-BL cable de fibra óptica InfiniBand 5 m SFP28 macho/macho

The BlueOptics JL296A-BL InfiniBand/fibre optic cable is a 5 m high-speed connection featuring SFP28 male connectors on both ends. Engineered for short-reach, high-bandwidth links, this cable supports 25G data rates and is suitable for direct-attached connections between switches, storage systems and servers in rack and adjacent-rack installations. The cable follows common industry mechanical and electrical interfaces for SFP28 modules to ensure straightforward integration into existing InfiniBand and Ethernet environments where SFP28 ports are supported.

Advantages

This 5 m SFP28 male-to-male cable provides a predictable physical link for 25GBase-CR/InfiniBand and related protocols over short distances. As a passive direct-attach style twinax solution it offers low latency, low power consumption and a simple plug-and-play installation without the need for external transceivers. The construction and component selection are aligned with accepted MSA guidelines to maintain compatibility and stable performance in standard rack-mounted networking hardware.

Suitable for

• Connecting switches to switches within the same rack or adjacent racks
• Linking servers to top-of-rack switches for 25G interconnects
• High-throughput storage interconnects and SAN links supporting SFP28
• InfiniBand and Fibre Channel or Ethernet setups that accept SFP28 direct-attach cables

Key specifications

• Length: 5 metres
• Connector type: SFP28 male — SFP28 male
• Supported data rates: up to 25 Gbit/s per lane (25GBase-CR compatible)
• Cable type: direct attach twinax copper (passive) suitable for short-reach links
• Typical use: rack and adjacent-rack interconnects for switches, servers and storage

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be linked. Ensure both devices support passive 25G direct-attach twinax connections and that ports are cleared of dust and debris before insertion. Align the keyed housing with the port, press until the latch engages, and verify link status through connected equipment diagnostics or LED indicators. For removal, depress the connector latch and gently pull the cable straight out to avoid damaging the port.

Recommendations

Use the cable for short-distance interconnects inside racks or between adjacent racks. Avoid tight bends and maintain the manufacturer’s minimum bend radius to preserve signal integrity. Confirm host hardware compatibility with passive SFP28 assemblies and, if necessary, request a sample or test the link in a non-production environment before widespread deployment.
