BlueOptics ASRN-BO InfiniBand/fibre optic cable 3 m SFP28 Male/Male

The BlueOptics ASRN-BO InfiniBand/fibre optic cable 3 m SFP28 Male/Male is a 3-metre active optical cable designed for high-speed interconnects. It uses SFP28 form-factor connectors on both ends to support short-range multimode fibre links and is intended for use in data centres, high-performance computing clusters and network equipment that accept SFP28 active optical connections. The cable integrates optical transmitters and receivers to carry digital signals over multimode fibre at high bandwidths while maintaining compatibility with systems built to accept equivalent Lenovo ASRN-style 100G SR4 active optical links.

Advantages

The BlueOptics ASRN-BO provides a compact active optical solution with SFP28 male-to-male connectivity that reduces electrical cable length and electromagnetic interference compared with copper alternatives. As an AOC it contains integrated optics on each end, enabling reliable optical signal conversion and consistent short-range high-throughput transmission. The 3 m length offers a balance between reach and rack-level cable management, making it suitable for top-of-rack and intra-rack links.

Suitable for

• Short-range interconnects in data centres and server rooms
• High-performance computing clusters and node-to-node links
• Top-of-rack and intra-rack switch-to-switch or switch-to-server connections
• Environments requiring SFP28 active optical connections for up to 100G applications

Key specifications

• Connector type: SFP28 male on both ends
• Cable type: Active optical cable with integrated transceivers
• Length: 3 metres
• Transmission medium: Multimode fibre
• Supported link class: Short-range, 100G-class SR4-compatible operation on multimode infrastructure

How to use

Install the BlueOptics ASRN-BO by inserting each SFP28 connector into the corresponding SFP28 port on your devices while the equipment is powered down or per vendor hot-swap guidance. Ensure connectors are clean and free of debris before mating. After connection, verify link status and speed through the device management interface and confirm the system recognises the active optical link as an SFP28 AOC. Use standard network diagnostics to confirm signal integrity and throughput.

Usage recommendations

Use this 3 m SFP28 AOC for intra-rack or short inter-rack connections where 100G-class, short-range multimode performance is required. Keep the cable within recommended bend radii, avoid sharp bends or crushing, and store/remove dust caps only when connecting. Confirm your network hardware explicitly supports SFP28 active optical modules compatible with Lenovo ASRN-style 100G SR4 links if device vendor compatibility is required.
