## Summary description

The BlueOptics SFP8181BU3MK is a 3 m fibre optic cable designed for high-speed data transmission. It features LC connectors and G.657.A1 fibre type, ensuring reliable performance and minimal signal loss. Ideal for InfiniBand applications, this cable is perfect for connecting devices in data centers and networking environments.

## Long description

The BlueOptics SFP8181BU3MK InfiniBand fibre optic cable 3 m LC Yellow is a single-mode patch cable engineered for high-speed data transmission in networking environments. With LC connectors on both ends and G.657.A1 fibre type, this 3-metre cable provides low attenuation and maintained signal integrity over short to medium interconnect distances. The yellow jacket and LC terminations make it easy to identify and install in data center racks and network equipment supporting InfiniBand protocols.
Advantages
This fibre optic cable uses G.657.A1 fiber construction to reduce bending losses and improve reliability in routed or ducted installations. The LC connectors provide a compact connection interface suited to high-density patch panels and transceiver modules. Being 3 metres long, the cable balances reach and manageability for typical rack-to-rack or shelf-to-shelf links, while the standardized termination and robust jacket support consistent performance and simplified replacement or scaling.
Suitable for
 InfiniBand interconnects between switches, host channel adapters and transceivers
 Data centre patch panels and high-density fibre shelves
 Server-to-switch or shelf-to-shelf short-range connections
 Environments requiring low-bend-loss single-mode fibre routing
Key specifications
 Length: 3 metres
 Connector type: LC to LC
 Fibre type: G.657.A1 single-mode
 Cable colour: Yellow
 Application: InfiniBand and high-speed data links
 Jacket: flexible, suitable for rack and conduit routing
How to use
Ensure both network devices are powered down or follow hot-plug guidelines of your equipment before inserting the LC connectors. Align the LC connectors with the transceiver or patch panel ports and insert until a secure click is felt. Route the cable to avoid sharp bends and mechanical stress; maintain bend radii appropriate for G.657.A1 fibre to preserve signal quality. If necessary, label both ends to match patching diagrams and document the link in network inventory systems.
Usage recommendations
For optimal performance in InfiniBand environments, verify transceiver compatibility with LC single-mode interfaces and keep cable runs within recommended distances for your hardware. Avoid tight bends and repeated flexing, and inspect connectors for dust or contamination before mating; use appropriate dust caps or cleaning tools when required.
