## Summary description

The BlueOptics SFP3133EU3MK is a 3 m InfiniBand fibre optic cable featuring 2x LC and 2x ST connectors. It utilizes OM3 fibre type with a core diameter of 50 µm, supporting full duplex communication. Ideal for high-speed data transmission in networking applications.

## Long description

The BlueOptics SFP3133EU3MK InfiniBand fibre optic cable is a 3 m duplex patch cable designed for high-speed data transmission in networking environments. It features two LC connectors on one end and two ST connectors on the other, terminated on OM3 multimode fibre with a 50 µm core diameter. The cable supports full-duplex communication and is intended for short to medium range links where InfiniBand or other high-bandwidth interconnects are required.
Advantages
This OM3 multimode cable provides low insertion loss and consistent signal quality for high-throughput applications. The combination of LC and ST connector types offers flexible connectivity between equipment with different port interfaces. With a 3 m length, the cable is suitable for rack-to-rack or device-to-device connections inside data centres, server rooms, and telecom cabinets while maintaining easy cable management.
Suitable for
 InfiniBand interconnects and high-performance computing clusters
 Short- to medium-distance links in data centres and server rooms
 Connections between devices with LC and ST ports
 Telecommunication and networking equipment requiring OM3 multimode fibre
Key specifications
 Fibre type: OM3 multimode
 Core diameter: 50 µm
 Length: 3 m
 Connector types: 2x LC to 2x ST
 Transmission mode: full duplex
 Application: InfiniBand and high-speed networking
How to use
Route the fibre cable carefully to avoid sharp bends and mechanical stress on the connectors and fibre jacket. Align and insert the LC connectors into LC ports and the ST connectors into ST ports until they click or lock into place, ensuring correct polarity for duplex transmission. Verify link status on connected devices and perform standard optical tests such as insertion loss or continuity checks if required. When disconnecting, release any connector latches and pull the connector body rather than the cable jacket.
Usage recommendations
Store and handle the cable in a clean environment to avoid contamination of connector end-faces. Use dust caps when connectors are not in use and follow manufacturer guidelines for fibre bend radius and cleaning procedures to maintain optimal optical performance.
