## Summary description

The BlueOptics SFP-25G-50CM-DE-BL is a 0.5 m InfiniBand fibre optic cable featuring SFP28 connectors on both ends. Designed for high-speed data transmission, it ensures reliable connectivity in data centers and networking environments. The male/male connector design allows for easy installation and compatibility with various devices.

## Long description

The BlueOptics SFP-25G-50CM-DE-BL InfiniBand fibre optic cable is a 0.5 m connection cable with SFP28 connectors on both ends. Designed for short-range high-speed links, it provides a direct attach solution for server, switch and storage interconnects where SFP28 ports are used. The male-to-male connector configuration enables straightforward installation and compatibility with equipment that accepts SFP28 modules.
Advantages
This 0.5 m SFP28 cable supports high-speed data transmission for InfiniBand and related networking protocols while keeping a compact form factor suitable for dense rack environments. The cable is built to industry mechanical and electrical interface standards to enable plug-and-play use with compatible hardware. Its short length reduces clutter and signal degradation for adjacent-rack and in-rack connections where a reliable, low-latency direct attach link is required.
Suitable for
Linking switches, routers and storage appliances with SFP28 ports over short distances
Rack-to-rack and in-rack connections in data centers and server rooms
High-speed InfiniBand and 25GBase-CR direct attach applications
Key specifications
Connector type: SFP28 male to SFP28 male on both ends
Length: 0.5 m
Designed for: InfiniBand and 25G direct attach applications
Cable colour: Black
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring the latch engages and the connectors are fully seated. Use the cable for short-range direct attach connections between equipment that explicitly supports SFP28 passive direct attach cables or equivalent SFP28 links. Avoid bending the cable sharply and install it so that it does not create strain on the ports.
Usage recommendations
Verify that both devices support SFP28 passive direct attach or the specific 25G/InfiniBand protocol in use before connecting. For optimal reliability, keep the cable length appropriate for in-rack or adjacent-rack runs and avoid environments with excessive mechanical stress or extreme temperatures.
