InfiniBand/fibre optic cable BlueOptics CBL-NTWK-0942-MQ28C20M-BL 2 m QSFP

The BlueOptics CBL-NTWK-0942-MQ28C20M-BL is a 2 m InfiniBand/fibre optic cable with QSFP connectors designed for high-speed data transmission and reliable connectivity in data center and networking environments. The cable supports low-latency links between switches, servers and storage systems where QSFP interfaces are used. Its 2 metre length balances reach and cable management for rack-mounted equipment and short inter-rack connections.

Advantages

This fibre optic cable provides high bandwidth capacity and signal integrity suitable for InfiniBand and other high-speed fabrics using QSFP interfaces. The BlueOptics cable is engineered for consistent performance over short to medium distances, with robust connectors that ensure stable mating and low insertion loss. The 2 m length simplifies routing in rack environments while reducing excess slack compared with longer assemblies.

Suitable for

• Interconnecting QSFP ports on switches and routers in data centers
• Server-to-switch connections in rack and blade server deployments
• High-performance computing (HPC) clusters using InfiniBand fabrics
• Storage area networks and SAN switches with QSFP interfaces

Key specifications

• Cable type: Fibre optic / InfiniBand compatible
• Connector type: QSFP (Quad Small Form-factor Pluggable)
• Length: 2 metres
• Color: Blue
• Intended use: Short interconnects in racks and data center topologies

How to use

Ensure both devices have compatible QSFP ports and are powered off or in a state that allows hot-plugging if supported. Align the QSFP connector with the port and insert firmly until the connector latches. Route the cable to avoid sharp bends and to maintain the minimum bend radius specified for the fibre type. Verify link status and perform basic diagnostics or speed tests to confirm a stable connection after installation.

Recommendations

For reliable performance, avoid excessive bending or crushing of the cable, keep connector end caps on until ready to plug in, and maintain clean connector interfaces. Select the 2 m length when short rack-to-rack or server-to-switch runs are required to improve airflow and cable management in dense installations.
