## Summary description

The BlueOptics CBL-503-BO is a 3 m InfiniBand fibre optic cable featuring QSFP28 connectors. It provides high-speed data transmission and is ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics CBL-503-BO InfiniBand Fibre Optic Cable 3 m QSFP28 Aqua is a 3‑metre active optical cable (AOC) with QSFP28 to QSFP28 connections designed for high‑speed short‑reach links. It follows MSA standards for QSFP28 interfaces and supports 100GBASE‑SR4 and InfiniBand applications over multimode fiber, providing simultaneous transmit and receive capability via integrated optical transceivers. The pre‑assembled aqua cable eliminates the need for additional patching and is intended for use in data centers, high‑performance computing and other installations requiring 100 Gbit/s links between switches, routers and storage hardware.
Advantages
The cable provides a factory‑assembled QSFP28 AOC solution that reduces connector handling and potential insertion loss compared with discrete transceiver plus patch cord assemblies. Integrated transmitter and receiver modules on each connector simplify signal integrity for 100 Gbit/s multimode links and reduce susceptibility to electromagnetic interference. Built to MSA QSFP28 physical and electrical guidelines, the product is suitable for systems that support 100GBASE‑SR4 or compatible InfiniBand QSFP28 AOCs, and includes digital diagnostics monitoring capability when supported by host hardware.
Suitable for
Short‑reach 100 Gbit/s links in data centre topologies
Interconnects between QSFP28 ports on switches, routers and storage arrays
High‑performance computing clusters and InfiniBand fabrics
Key specifications
Connector type: QSFP28 to QSFP28 (male)
Cable type: Active Optical Cable (AOC) with multimode fibre
Length: 3 metres
Supported protocols: 100GBASE‑SR4 and compatible InfiniBand applications
Colour: Aqua (multimode fibre standard colour)
Digital diagnostics: DDM/DOM supported when host hardware provides support
How to use
Install by inserting each QSFP28 connector into the corresponding QSFP28 port until the latch engages. Ensure that the host ports support QSFP28 AOCs and the 100GBASE‑SR4 or InfiniBand protocol required. Route the cable to avoid sharp bends and mechanical stress; maintain the recommended minimum bend radius for multimode fibre to preserve optical performance. If the host system supports DDM/DOM, verify diagnostic readings through the host management interface to confirm optical power, temperature and supply values.
Usage recommendations
Use the cable in matched multimode QSFP28 ports and avoid mixing with unsupported vendor‑locked transceiver configurations. Keep connector endfaces and QSFP28 port areas free of dust and debris; do not attempt to disassemble the factory‑assembled AOC. For reliable long‑term operation, follow data centre cable management best practices and confirm DDM/DOM reporting via the host system when performing troubleshooting.
