BlueOptics CBL-502-BO InfiniBand/fibre optic cable 2 m QSFP28 Aqua

The BlueOptics CBL-502-BO InfiniBand/fibre optic cable 2 m QSFP28 Aqua is a 2‑metre active optical cable with QSFP28 to QSFP28 male connectors designed for high‑speed short‑range links in data centers and networking equipment. The cable uses multi‑mode fibre and supports 100GBASE‑SR4 transmission over a 2 m length. Its aqua jacket and QSFP28 form factor make it suitable for standard 100GbE, InfiniBand and other high‑speed optical interfaces that accept QSFP28 AOC modules.

Advantages

The cable provides a pre‑terminated, plug‑and‑play optical link that eliminates the need for field termination and patch cord cleaning. As an active optical cable, it integrates transmitters and receivers in the QSFP28 housings to deliver 100 Gbit/s class performance over multi‑mode fibre while minimizing electromagnetic interference. Digital diagnostic monitoring (DDM/DOM) is available when supported by the host hardware, enabling real‑time readout of operating parameters for simplified maintenance.

Suitable for

• Short‑reach 100GbE connections between switches and routers in data centers
• High‑speed InfiniBand links for HPC and server interconnects
• Interconnections of storage systems and network appliances supporting QSFP28 AOCs
• Environments requiring an AOC with simple installation and low electromagnetic susceptibility

Key specifications

• Connector type: QSFP28 to QSFP28 (male/male)
• Length: 2 metres
• Transmission: 100GBASE‑SR4 class over multi‑mode fibre
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Colour: Aqua jacket for multi‑mode identification
• Diagnostic: Digital Diagnostic Monitoring (DDM/DOM) support when enabled by host

How to use

Install the BlueOptics CBL-502-BO by plugging each QSFP28 connector into the corresponding QSFP28 port on your switches, routers or servers while the devices are powered according to your equipment vendor guidelines. Ensure the host hardware supports QSFP28 AOC modules and, if needed, DDM/DOM monitoring. No field termination is required; the pre‑assembled fibre core eliminates patching and cleaning of individual fibre connectors. Follow standard handling precautions for optical modules and avoid bending the cable beyond the recommended radius.

Usage recommendations

Confirm compatibility with your network hardware vendor for QSFP28 AOC modules and verify that the target ports support 100GBASE‑SR4 or the intended protocol before deployment. For diagnostics, enable DDM/DOM in host firmware if you need real‑time monitoring of optical parameters. Store and route the cable to avoid tight bends and mechanical stress to maintain long service life.
