Cabo de fibra ótica InfiniBand BlueOptics X66240A-05-BL 0,5 m SFP28

The BlueOptics X66240A-05-BL is a 0.5 m InfiniBand/fibre optic cable with SFP28 connectors on both ends. Designed for short-reach, high-speed links in rack environments, this cable supports 25G data rates and is intended for direct-attach connections between switches, routers, storage systems and other hardware that accept SFP28 interfaces.

Advantages

This 0.5 m BlueOptics cable combines a compact length with SFP28-to-SFP28 connectivity to enable low-latency, high-throughput links in dense rack installations. As a passive direct-attach solution for short distances, it offers low power consumption and a simple design with minimal points of failure. The cable is manufactured to MSA-compliant SFP28 specifications and is suitable for environments where consistent, vendor-compatible 25G links are required.

Suitable for

• Short-reach interconnects inside racks and between adjacent racks
• 25G Ethernet, FCoE and InfiniBand links supporting SFP28
• Connections between switches, routers and storage systems with SFP28 ports

Key specifications

• Length: 0.5 m
• Connector type: SFP28 to SFP28
• Rated data rate: up to 25 Gbps
• Cable type: passive direct attach (twinax copper/DAC characteristics for short distance electrical signalling)
• Conductor gauge reference: 30 AWG
• Compliance: MSA-compliant SFP28 form factor

How to use

Connect each SFP28 connector to the corresponding SFP28 port on the network devices you intend to link. Ensure both devices support passive direct-attach twinax or SFP28 electrical interconnects at 25G. Route the 0.5 m cable within the rack to avoid sharp bends and mechanical strain. No external power or transceiver configuration is required beyond confirming that the host hardware accepts passive DAC links.

Recommendations

For reliable operation, use the cable for short-distance connections (within a rack or between adjacent racks) only, avoid excessive bending or crushing, and verify host device compatibility with passive SFP28 direct-attach cables and 25GBase-CR signaling.
