## Long description

The BlueOptics SFP2121BU30MK InfiniBand fibre optic cable is a 30 m single-mode patch cable with LC connectors and OS2 fiber. Designed for high-speed links in data centers and enterprise networks, this yellow cable provides consistent optical performance over longer distances while maintaining compact LC termination. The 125 µm core diameter supports standard single-mode transmission characteristics suitable for InfiniBand infrastructure.
Advantages
This InfiniBand fibre optic cable delivers stable signal transmission with low attenuation thanks to OS2 single-mode fiber construction. The LC duplex connectors ensure secure, repeatable connections and occupy minimal port space in patch panels and transceivers. With a 30 m length and durable jacket, the cable is appropriate for trunking and inter-rack connections where consistent optical performance is required.
Suitable for
 InfiniBand links between switches, servers, and storage systems

How to use
Route the cable between the required transceivers or patch panel ports, ensuring LC connectors are aligned and fully inserted into compatible InfiniBand SFP+ or SFP28 transceivers and LC adapters. Avoid tight bends or kinks in the cable; maintain the minimum bend radius recommended for single-mode fiber during installation. Test the link with appropriate optical testing equipment to verify insertion loss and link integrity after installation.
Usage recommendations
