## Summary description

The BlueOptics CBL-550-BO is a 50 m InfiniBand fibre optic cable featuring QSFP28 connectors.

## Long description

The BlueOptics CBL-550-BO InfiniBand Fibre Optic Cable 50 m QSFP28 Aqua is a 50‑metre active optical cable (AOC) with QSFP28 male‑to‑male connectors designed for high‑speed InfiniBand and 100G applications. Engineered to follow MSA QSFP28 standards, this aqua multi‑mode fibre assembly provides optical transmission between compatible QSFP28 ports and is intended for data centre interconnects, switches, routers and storage systems that accept QSFP28 AOC connections.
Advantages
This 50 m BlueOptics AOC offers a pre‑assembled optical link that eliminates the need for separate transceivers and patching, reducing insertion loss and avoiding connector cleaning. The cable integrates transmitter and receiver modules on each end to support simultaneous send/receive operation, and includes Digital Diagnostics Monitoring (DDM/DOM) support when the host hardware exposes these functions. Built to MSA mechanical and electrical profiles, the cable aims to be compatible with equipment that supports QSFP28 AOC interfaces for short‑reach 100G or InfiniBand links.
Suitable for
Data centre switch-to-switch and switch-to-server connections
High‑performance computing (HPC) InfiniBand interconnects
Storage system links and SAN uplinks
Short‑reach 100G Ethernet connections in networking racks
Key specifications
Cable type: Active Optical Cable (AOC) with multi‑mode fibre
Length: 50 metres
Connector type: QSFP28 male to QSFP28 male
Colour: Aqua (multi‑mode identification)
Supported protocols: 100GBASE‑SR4 and InfiniBand short‑reach signaling (as supported by host devices)
Digital diagnostics: DDM/DOM support when available through host hardware
How to use
Install the BlueOptics CBL-550-BO by inserting each QSFP28 connector into the corresponding QSFP28 ports on the devices to be linked, taking care to align the connector keying. No additional transceivers or patch cords are required. Ensure both endpoints and their firmware support QSFP28 AOC modules and, if needed, enable or check DDM/DOM status via the host management interface to access diagnostic parameters such as optical power and temperature.
Usage recommendations
Route the cable to avoid sharp bends and mechanical strain; observe minimum bend radius guidelines for multi‑mode AOCs. Verify host compatibility with QSFP28 AOC modules and check that the destination equipment supports the intended protocol (100GBASE‑SR4 or InfiniBand). For reliable diagnostics, confirm DDM/DOM support in the hardware and use monitoring tools provided by the host platform.
