InfiniBand/fibre optic cable BlueOptics CBL-NTWK-0325-02-BL 2 m QSFP Male/Male

The BlueOptics CBL-NTWK-0325-02-BL is a 2 m InfiniBand / fibre optic cable with QSFP male-to-male connectors designed for high-speed rack and adjacent-rack connections. This direct-attach type cable supports 40GBase-CR4 transmission modes and is intended for short-distance links between switches, routers, storage systems and other compatible hardware. The cable uses a QSFP-to-QSFP interface and a 30 AWG conductor profile suitable for passive twinax copper deployments where supported by the connected devices.

Advantages

This cable offers a compact, low-latency connection for high-bandwidth links up to 40 Gbit/s over a 2 m distance. Passive direct-attach construction results in low power consumption and a simple design with a low failure rate. Manufacturing and component selection follow established MSA guidelines, providing compatibility with major hardware platforms that support the same 40GBase-CR4 direct-attach interfaces.

Suitable for

• Short-distance server-to-switch and switch-to-switch links inside racks
• High-bandwidth interconnects in data centers and server rooms
• Storage system connections supporting 40G Ethernet, FCoE or InfiniBand signaling

Key specifications

• Cable length: 2 meters
• Connector type: QSFP male to QSFP male
• Supported data rate: up to 40 Gbit/s (40GBase-CR4 compatible)
• Cable type: passive twinax / direct attach copper with 30 AWG conductor profile
• Target use: short-reach rack and adjacent-rack interconnects

How to use

Verify that both ends of your network hardware support passive QSFP direct-attach twinax connections and the 40GBase-CR4 transmission mode. Align the QSFP connectors with the device ports and insert each connector until it seats securely; ensure retention latches engage where present. Route the 2 m cable to avoid sharp bends and mechanical strain; maintain recommended bend radius for twinax cables. If hot-plugging is required, follow your hardware vendor's hot-swap guidelines to prevent link disruptions.

Recommendations

Use this cable in short-reach, high-bandwidth installations where passive QSFP direct-attach twinax is supported. For longer distances or active optical requirements, select appropriately specified active optical cables or transceiver-based fibre solutions. Inspect connectors for contamination before mating and avoid excessive bending or pulling to preserve signal integrity and mechanical life.
