## Summary description

The BlueOptics X66240A-05-BL is a 0.5 m InfiniBand/fibre optic cable featuring SFP28 connectors on both ends. It ensures high-speed data transmission and is ideal for data centers and networking applications.

## Long description

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.
Usage 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.
