Cabo InfiniBand/fibra ótica BlueOptics CAB-Q-4S-100G-5M 5m QSFP28 4xSFP28 macho/macho

The BlueOptics CAB-Q-4S-100G-5M is a 5-meter InfiniBand/fibre optic break-out cable with a QSFP28 connector on one end and four SFP28 connectors on the other. Designed for high-density networking, this male-to-male cable supports 100G aggregate throughput via four independent 25G lanes, providing a compact, factory-terminated link for short-reach connections in data centres and HPC clusters.

Advantages

This break-out cable delivers high aggregated bandwidth while reducing the number of separate transceiver modules and patch cords required, simplifying cabling management. The integrated QSFP28-to-4xSFP28 configuration enables low-latency, direct connections between QSFP28 ports and multiple SFP28 ports without the need for additional adapters. Its 5 m length offers flexibility for rack-to-rack or within-rack connections where predictable signal performance is needed.

How to use

Inspect connectors and cable for damage before installation. Insert the QSFP28 connector into the QSFP28 port and each SFP28 connector into the corresponding SFP28 ports until the latches engage. Ensure that equipment ports are powered down or in a state recommended by the equipment manufacturer if live hot-plugging is not supported. Route the cable to avoid tight bends and excessive strain; maintain recommended bend radius for multimode fibre to preserve signal integrity.

Recommendations

Use this cable for short-reach, high-bandwidth links inside racks and between adjacent racks. Verify compatibility with host equipment and firmware for break-out mode and lane mapping before deployment. Store and handle the cable according to fibre best practices, avoiding kinks, sharp bends and contamination of connector endfaces.
