BlueOptics JL295A-BL InfiniBand fibre optic cable 3 m SFP28 Male Male

The BlueOptics JL295A-BL InfiniBand fibre optic cable is a 3 m connection cable with SFP28 male-to-male connectors designed for high-speed short-reach links in data centers and network racks. It provides a direct physical link between SFP28 ports on switches, servers and storage devices, supporting 25G-class InfiniBand and Ethernet-compatible environments where SFP28 optics are used. The cable is intended as a reliable interconnect for adjacent rack units and short in-rack runs requiring compact SFP28 form-factor connections.

Advantages

This 3 m SFP28 male-to-male cable offers a compact, low-latency physical connection suitable for high-speed server and switch interconnects. The SFP28 interface maintains compatibility with equipment that accepts SFP28 modules for 25G data rates. The cable’s 3 metre length provides flexibility for common rack and short-span topologies while minimizing excess cabling. Designed for use in professional networking environments, it supports InfiniBand and Ethernet-like transmission modes when used with compatible hardware.

Suitable for

• Direct links between SFP28 ports on switches and servers within the same rack or adjacent racks
• Interconnecting storage devices and network appliances that accept SFP28 connections
• Short-reach InfiniBand or 25G-capable Ethernet connections where SFP28 is supported

Key specifications

• Cable type: InfiniBand fibre optic style connection using SFP28 form-factor
• Connector type: SFP28 male to SFP28 male
• Length: 3 metres
• Supported data class: 25G-class links (SFP28-compatible environments)
• Typical use: short-reach rack and adjacent-rack interconnects

How to use

Ensure both devices have SFP28 ports and support the intended 25G/InfiniBand-compatible signaling. With devices powered down or following hot-plugging guidelines of the equipment vendor, insert each SFP28 plug into the corresponding SFP28 port until the latch engages. Route the 3 m cable to avoid sharp bends and mechanical strain on connectors. After connection, verify link status on both devices and confirm negotiated speed and protocol in the host or switch management interface.

Recommendations

Use this SFP28 cable for short-distance links inside racks or between adjacent racks. Keep bend radius within manufacturer guidelines, avoid kinking, and secure cable runs to reduce strain. Verify compatibility with your switch or server vendor for passive or active link requirements and test link operation after installation.
