InfiniBand/kuitu-kaapeli BlueOptics X66240A-5-BL 5 m SFP28

The BlueOptics X66240A-5-BL is a 5 m high-speed cable with SFP28 connectors on both ends, designed for short-range InfiniBand and fibre optic applications. It supports 25G data rates and is intended for use in data centres and rack-to-rack links where low latency, reliable transmission and minimal signal loss are required. The cable is compatible with hardware platforms that accept SFP28 connections and is offered as a cost-efficient alternative for short-distance high-bandwidth interconnects.

Advantages

This 5 m SFP28 cable provides a single-cable solution for 25G connectivity with reliable electrical signal transfer over short distances. The product is built to meet common MSA-compliant SFP28 interface requirements and offers low power consumption and low latency typical of passive direct-attach or short-reach interconnects. Quality components and testing for vendor compatibility help ensure consistent performance and long service life in demanding networking environments.

Suitable for

• Data centre top-of-rack and adjacent-rack interconnects
• High-speed server-to-switch or switch-to-switch links supporting SFP28
• Storage networking and Fibre Channel or FCoE deployments that accept SFP28 25G links
• InfiniBand short-reach connections where SFP28 interfaces are supported

Key specifications

• Length: 5 metres
• Connector type: SFP28 to SFP28
• Rated data rate: up to 25 Gbit/s
• Cable type: short-reach direct attach / twinax style for 25G electrical signalling
• Compliance: MSA-aligned SFP28 interface compatibility

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your devices until the latch engages. Ensure both devices support 25GBase-CR or the equivalent 25G electrical protocol and that firmware or driver settings allow passive direct-attach or short-reach twinax connections if required. Route the cable to avoid tight bends and mechanical stress; maintain the 5 m distance for optimal signal integrity. After physical installation, verify link status and negotiate the proper speed on connected devices.

Recommendations

Use this cable for short-distance, high-bandwidth links inside racks or between adjacent racks. Confirm compatibility with your switch, router or storage platform and test link operation after installation. Avoid extreme bending, excessive pulling force and exposure to fluids or heat sources to preserve signal performance and cable lifespan.
