## Long description

The BlueOptics InfiniBand/fibre optic cable 15 m SFP28 Male/Male is a 15-metre duplex fibre cable with SFP28 form-factor connectors on both ends, designed for high-speed data transmission in server, storage and switch interconnects.

Its 15 m length offers flexibility in rack-to-rack or within-rack installations while keeping a small physical footprint. The male/male SFP28 connectors simplify insertion into compatible transceiver slots and ensure consistent mechanical alignment for repeated use.
Suitable for
 Interconnecting servers and switches in data centres

Key specifications
 Cable type: duplex fibre optic cable with SFP28 connectors
 Length: 15 metres
 Connector gender: male to male (SFP28 form factor)
 Supported interface: InfiniBand and compatible high-speed fibre interfaces
 Typical use: short- to medium-reach data centre interconnects
How to use
Ensure both network devices support SFP28 transceivers or SFP28 direct-attach cables and are powered off or have hot-swap capability per manufacturer guidance. Align the SFP28 connectors with the transceiver slots and insert until the latch engages. Verify link status on connected devices and check for expected speed and lane status in device management interfaces. When removing, depress the latch and pull the connector straight out to avoid damaging the transceiver.
Usage recommendations
Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius. Keep connectors capped when not in use to prevent contamination. For optimal performance, use in environments with controlled temperature and humidity and periodically inspect connectors for dust or damage before connection.
