Cable InfiniBand/fibra óptica BlueOptics 470-ACEX-BL 1 m SFP28 conector macho/conector macho

The BlueOptics 470-ACEX-BL is a 1 m InfiniBand/fibre optic cable with SFP28 male connectors on both ends. Designed for short-reach, high-speed links, this cable supports 25G data rates and a direct attach connection between SFP28-equipped devices. It is intended for rack-to-rack or within-rack interconnects in data centers and networking equipment where a passive direct attach form factor is suitable.

Advantages

This SFP28 male-to-male cable provides a compact, low-latency connection for 25G interfaces and follows MSA-compliant connector dimensions for broad compatibility with SFP28 ports. As a passive direct attach solution, it consumes minimal power and has a simple design that reduces potential points of failure. The construction uses 30 AWG twinax copper conductors appropriate for short-distance electrical transmission and is suited for use with switches, routers and storage systems that accept SFP28 passive DAC cables.

Suitable for

• Short-reach interconnects within racks and between adjacent racks
• 25GBase-CR direct attach connections for switches and routers
• High-speed links for storage systems, NICs and InfiniBand-capable devices

Key specifications

• Length: 1 meter
• Connector type: SFP28 male to SFP28 male
• Transmission rate: up to 25 Gbit/s
• Cable type: passive twinax (copper), 30 AWG
• Form factor: Direct Attach Cable (DAC), passive
• Compliance: MSA-compatible SFP28 physical interface

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring the latch engages and the connector is fully seated. Use the 1 m length for short-distance connections within racks or between adjacent racks. No external power or transceivers are required for passive direct attach operation; ensure connected hardware officially supports passive SFP28 DACs and the 25GBase-CR electrical protocol before deployment.

Recommendations

For reliable operation, verify compatibility with the target switch, router or storage platform and confirm firmware or software requirements where applicable. Route the cable to avoid tight bends, mechanical strain or abrasion, and maintain recommended bend radius for 30 AWG twinax. Use passive DACs for short distances only; for longer runs or optical isolation, choose active DACs or optical transceivers with appropriate fibre cabling.
