## Summary description

The BlueOptics CAB-Q-4S-100G-5M is a 5-meter InfiniBand/fibre optic cable featuring a QSFP28 connector on one end and four SFP28 connectors on the other. This male-to-male cable is designed for high-speed data transmission, making it ideal for data centers and high-performance computing environments.

## Long description

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.
Suitable for
 Interconnecting QSFP28 ports to multiple SFP28 ports in switches and servers
 High-performance computing clusters and InfiniBand fabrics
 Short-reach data centre links and top-of-rack cabling
 Consolidating multiple 25G links into a single 100G trunk
Key specifications
 Cable type: multimode fibre break-out cable
 Connector ends: QSFP28 (male) to 4 × SFP28 (male)
 Nominal length: 5 meters
 Aggregate throughput: up to 100 Gbps (4 × 25 Gbps lanes)
 Intended reach: short-reach / within-data-centre links
 Compatible transceiver form factors: QSFP28 and SFP28
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.
Usage 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.
