BlueOptics SFP-25G-C3M-BL InfiniBand fibre optic cable 3 m SFP28 Male/Male

The BlueOptics SFP-25G-C3M-BL InfiniBand fibre optic cable 3 m SFP28 Male/Male is a 3‑metre direct attach cable designed for short-range, high‑speed connections between SFP28 ports. It is intended to carry 25G signaling for Ethernet, FCoE, Fibre Channel and InfiniBand applications on compatible hardware platforms. The cable uses SFP28 form‑factor connectors on both ends and is specified for linking equipment within racks or across adjacent racks where passive twinax or compatible direct attach cabling is supported.

Advantages

The cable provides a compact, low‑latency physical link that requires no external power for the passive variant and offers predictable signal performance for 25G data rates over the 3 m distance. Manufactured with components from established suppliers and tested for compatibility, the product is suitable for dense rack deployments and reduces overall power and cooling demands compared with active optical modules. Its form factor and construction support straightforward plug‑and‑play installation in systems that accept SFP28 direct attach cables.

Suitable for

• Interconnecting switches, routers and storage systems within the same rack or adjacent racks
• 25G Ethernet, Fibre Channel, FCoE and InfiniBand short‑reach links
• High‑density top‑of‑rack deployments requiring low latency and low power

Key specifications

• Cable length: 3 m
• Connector type: SFP28 male to SFP28 male
• Supported data rate: up to 25 Gbps per link
• Physical medium: passive direct attach twinax copper cable compatible with 25GBase‑CR applications
• Wire gauge: 30 AWG construction
• Form factor: SFP28 compliant, MSA compatible

How to use

Insert each SFP28 connector into the corresponding SFP28 port on your networking devices until the latch engages. Ensure the connected devices officially support passive 25G direct attach twinax cables and the chosen transmission protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). No additional configuration is required on many platforms beyond verifying link settings and speed negotiation; check the hardware vendor documentation for any vendor‑specific enablement steps or firmware recommendations.

Recommendations

Verify compatibility with your switch, router or storage vendor before deployment and, where possible, test a sample cable in your target environment. Avoid sharp bends and maintain a minimum bend radius consistent with the cable construction to preserve signal integrity and service life.
