BlueOptics XS+DA0002-BL cable de fibra óptica InfiniBand 2 m SFP28 conector macho/macho

The BlueOptics XS+DA0002-BL InfiniBand fibre optic cable is a 2 m connection cable with SFP28 male connectors on both ends, designed for short-reach, high-speed links in racks and adjacent rack rows. It supports 25G data rates and is intended as a direct attach solution for switches, routers, storage arrays and other hardware that accepts SFP28 interfaces. The cable implements a passive 25GBase-CR twinax copper configuration with 30 AWG conductors and complies with MSA electrical and mechanical dimensions to ensure interoperable mating with standard SFP28 ports.

Advantages

This cable provides a compact two-meter link suitable for dense rack deployments where low latency and minimal power consumption are required. The SFP28 male-to-male configuration allows direct insertion into SFP28 ports without transceivers, reducing component count and installation complexity. Built to MSA guidelines and produced using industry-grade cable and connector components, it is suitable for standard 25G Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand applications over short distances.

Suitable for

• Short-reach rack-to-rack connections in data centers
• Interconnects between switches, routers and storage systems
• High-throughput links requiring 25G bandwidth and low latency
• Environments where passive direct attach twinax cabling is supported

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 2 m
• Data rate support: up to 25 Gbit/s
• Cable type: passive twinax (25GBase-CR) with 30 AWG conductors
• Compliance: MSA-compatible electrical and mechanical form factor
• Typical applications: Ethernet, FCoE, InfiniBand over short distances

How to use

Insert each SFP28 connector directly into the corresponding SFP28 port on your networking equipment until the latch engages. Ensure both devices support passive direct attach twinax cables and the same transmission protocol (for example 25GBase-CR or compatible 25G physical interfaces). Route the cable to avoid tight bends and mechanical stress; maintain the specified bend radius to preserve signal integrity. For best results, perform link negotiation and verify the link state through device management interfaces after installation.

Recommendations

Use this 2 m passive SFP28 cable for short-distance connections inside racks or between adjacent racks where the host equipment explicitly supports passive DAC twinax SFP28 interconnects. Avoid deploying the cable for longer spans than specified, in environments with excessive vibration, or where hot-pluggable active transceivers are required by the hardware. When in doubt, test a sample link in your target hardware to confirm compatibility and performance.
