## Summary description

The BlueOptics BK837A is a 0.5 m InfiniBand fibre optic cable featuring LC connectors and OM3 fibre type. It supports full duplex communication with a core diameter of 125 µm, making it ideal for high-speed data transmission in data centers and networking applications.

## Long description

The BlueOptics BK837A InfiniBand fibre optic cable 0.5 m LC OM3 is a short, high-performance multimode patch cable designed for high-speed data transmission in rack, switch and server interconnects. The cable uses OM3 multimode fibre with a 125 µm core diameter and LC connectors on both ends to provide reliable full-duplex links where low latency and consistent throughput are required. With a compact 0.5 m length, this fibre cable is suited to tidy, short-reach connections inside equipment cabinets and dense networking panels.
Advantages
OM3 multimode construction supports high bandwidth for InfiniBand and multimode Ethernet applications while maintaining signal integrity over short distances. LC connectors offer a small form factor that fits high-density ports and minimizes port crowding. The 0.5 m length reduces excess cabling, improves airflow in racks and simplifies cable management. The cable is suitable for environments where predictable performance and low insertion loss are important.
Suitable for
 Short-reach connections between switches, routers and servers
 InfiniBand fabrics and high-performance computing clusters
 Patch panels and high-density transceiver ports
 Data centre rack and cabinet cabling
Key specifications
 Fibre type: OM3 multimode
 Connector type: LC to LC
 Length: 0.5 m
 Core diameter: 125 µm
 Transmission mode: Full duplex
 Application: InfiniBand and multimode optical networks
How to use
Inspect connectors for dust or damage before installation and clean with appropriate fibre cleaning tools if necessary. Route the cable to avoid sharp bends and keep bend radius within manufacturer guidelines for OM3 multimode fibre. Insert LC connectors into compatible LC ports on transceivers, switches or servers until they click into place. For removal, depress the latch on the LC connector and gently pull straight out to avoid strain on the fibre.
Usage recommendations
Store and handle the cable in a clean environment to prevent contamination. Use dust caps when ports or connectors are not in use. For best performance in InfiniBand deployments, pair the cable with transceivers and equipment rated for OM3 multimode operation and verify link status after installation.
