## Long description

The BlueOptics InfiniBand/fibre optic cable 15 m QSFP28 Male/Male is a high-speed multimode optical cable designed for data center and enterprise networking applications. With QSFP28 connectors on both ends and a 15 metre length, this fibre optic cable facilitates low-latency, high-bandwidth connections between switches, servers and storage systems. It is suitable for short to medium reach links inside racks and across adjacent cabinets where reliable 100GbE or InfiniBand connectivity is required.
Advantages
This fibre optic cable supports QSFP28 interfaces and is engineered for consistent signal integrity and minimal insertion loss. The 15 m length provides flexibility in equipment placement without compromising performance. A male-to-male connector configuration ensures simple plug-and-play installation and compatibility with standard QSFP28 ports. The cable construction offers resistance to typical installation stresses and maintains stable data throughput for demanding networking tasks.
Suitable for
100 Gigabit Ethernet interconnects within data center racks
InfiniBand high-performance computing links
Server-to-switch and switch-to-switch short-reach connections
Storage area network (SAN) interconnections
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 15 m
Transmission medium: multimode fibre optic
Supported interfaces: InfiniBand and 100GbE-class links
Typical use case: short to medium reach intra-rack and inter-rack connections
How to use
Inspect both connectors for cleanliness before installation and, if necessary, clean fibre end faces with an appropriate cleaning tool. Align the QSFP28 connectors with the device ports and insert until the latch engages. Verify link status on connected devices and monitor for expected data rates. Avoid sharp bends and excessive tension on the cable during routing. If relocation is required, power down or follow hot-swap procedures recommended by the equipment manufacturer to avoid transient link issues.
Usage recommendations
For optimal performance, route the cable with gentle bends exceeding the fibre's minimum bend radius, maintain proper strain relief at connection points, and keep connector end faces protected when not in use. Use this QSFP28 male-to-male fibre cable in controlled data centre environments to ensure consistent 100GbE or InfiniBand throughput and low latency.
