CBO InfiniBand cable CBL-QSFP-40GE-30M-F10-BO — QSFP, 30 m, fiber optic

InfiniBand cable CBO CBL-QSFP-40GE-30M-F10-BO is a 30-meter fiber-optic QSFP link engineered for high-throughput, low-latency connections in data centers and high-performance computing environments. The cable provides a single QSFP interface supporting 40GE-class links and is intended for inter-switch, server-to-switch and rack-to-rack interconnects where long-reach fiber is required. Constructed for professional networking installations, it is compatible with equipment that accepts QSFP transceivers or direct-attach QSFP interfaces and is suitable for environments that prioritize signal integrity and consistent throughput.

Advantages

The fiber-optic construction reduces electromagnetic interference and maintains stable signal quality over longer distances compared with copper alternatives. A 30 m length enables flexible routing between racks and across larger equipment rooms without intermediate repeaters. The QSFP form factor supports aggregated 40GE-class bandwidth in a single connector, simplifying cabling topology and reducing port density requirements on switches and hosts.

Key specifications

How to use

Install the cable by inserting the QSFP connector into the appropriate QSFP port on each device, ensuring the latch engages securely. Route the cable through cable management trays or ties to avoid sharp bends and maintain the minimum bend radius specified by the fiber type. Verify link status on connected devices and confirm negotiated speed and link health through equipment diagnostics or management interfaces. If using QSFP transceivers, ensure transceiver types and optical specifications match on both ends before establishing the link.

Recommendations

For reliable operation, follow manufacturer guidance on bend radius, connector cleanliness and environmental conditions. Clean connectors before mating, avoid excessive bending or tension, and use proper cable management to preserve signal quality. Confirm compatibility of QSFP ports and transceiver optics to guarantee expected 40GE-class performance.
