BlueOptics B2UZ-BO InfiniBand fibre optic cable 1 m QSFP28 Aqua

The BlueOptics B2UZ-BO InfiniBand fibre optic cable 1 m QSFP28 Aqua is a 1‑metre active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G data links in data centers and high‑performance networking environments. The cable follows MSA QSFP28/100GBASE‑SR4 conventions, integrates transmitters and receivers at each end for multimode fibre transmission, and supports low latency, high throughput interconnects between switches, routers and storage systems that accept QSFP28 AOCs.

Advantages

This active optical cable offers vendor‑compatible functionality for systems that support the Lenovo B2UZ 100GBASE‑SR4 AOC standard, enabling plug‑and‑play replacement in many major hardware platforms. Built to MSA specifications, it uses laser-based optical transceivers and quality IC components to provide stable 100G transmission over multimode fibre with digital diagnostics (DDM/DOM) support for real‑time monitoring of voltage, temperature, optical transmit/receive power and laser bias. The pre‑assembled AOC design eliminates the need for patching or cleaning patch cords and reduces insertion loss compared with field‑terminated links.

Suitable for

• 100G interconnects between QSFP28 ports in data center switches and routers
• High‑performance server to switch or switch to switch links in rack environments (1 m reach)
• Storage area network links and fibre channel over Ethernet applications up to 100G

Key specifications

• Cable type: Active Optical Cable (AOC) with QSFP28 to QSFP28 connectors
• Length: 1 metre
• Data rate: up to 100 Gbit/s (100GBASE‑SR4 compatible)
• Fibre: multimode optical transmission with integrated TX/RX modules
• Form factor: QSFP28 duplex interface, simultaneous send/receive capability
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) per SFF‑8472
• Typical use: short‑reach high‑speed interconnects in rack and data center environments

How to use

Insert the QSFP28 connectors into compatible QSFP28 ports on the devices to be connected, ensuring the connector orientation and port compatibility. Verify that connected hardware supports QSFP28 AOCs and, if required, enable or check the DDM/DOM status via the host device to monitor optical parameters. Because the cable is pre‑terminated, no field splicing or polishing is required; handle the cable by the connector housings and avoid sharp bends to maintain optical performance.

Usage recommendations

Prefer multimode QSFP28 ports designed for 100GBASE‑SR4 or vendor‑compatible AOCs, confirm DDM/DOM support in host hardware if remote diagnostics are required, and maintain bend radii and cable management consistent with vendor guidance to ensure long‑term reliability and minimal signal loss.
