## Summary description

Good Connections Alcasa fibre optic patch cable, 3 m length, OM3 multimode fibre with 50 µm core and ST connector on one end and LC on the other. Full‑duplex design supports duplex data links in datacentres, networking racks and fibre channel/InfiniBand environments. Suitable for high‑speed short‑reach links and patching between ST and LC ports.

## Long description

Good Connections Alcasa 3 m OM3 ST–LC duplex fibre optic patch cable is a multimode link designed for short‑reach, high‑speed connectivity. The cable uses 50 µm core multimode fibres with OM3 specification, terminated with an ST connector on one end and an LC connector on the other in a duplex configuration. It is intended for patching and linking between devices and racks where an ST interface must connect to an LC interface, offering reliable optical transmission for data centre and networking applications.
Advantages
The OM3 multimode construction provides high modal bandwidth suitable for 10 Gb/s and some higher short‑reach applications, while the 50 µm core ensures compatibility with standard multimode transceivers. The ST connector offers bayonet-style mechanical stability for legacy equipment and field installations, and the LC connector provides a compact footprint for high‑density panels. The duplex design supports bi‑directional full‑duplex links without additional cabling complexity.
Suitable for
Patching between ST and LC ports in network racks and cupboards
Short‑reach links in data centres and server rooms
Fibre channel and InfiniBand short‑reach interconnects
Upgrading or bridging legacy ST equipment to LC‑based systems
Key specifications
Fibre type: Multimode OM3
Core diameter: 50 µm
Length: 3 m
Configuration: Duplex
Connector A: ST (male)
Connector B: LC (duplex)
Typical applications: Data centre patching, short‑reach networking
How to use
Connect the ST end to the device or panel with an ST receptacle and insert the LC duplex end into the LC port of the target device or patch panel. Ensure connectors are clean before mating to avoid optical power loss; use a fibre inspection scope or lint‑free wipes with appropriate cleaning fluid. Route the cable to avoid sharp bends and mechanical stress, maintaining the minimum bend radius specified by the fibre manufacturer. For duplex links, match transmit and receive channels according to equipment port labelling or port mapping.
Usage recommendations
Store and handle the fibre cable in a clean environment, keep protective dust caps on connectors when not in use, and avoid kinking or excessive pulling force. For optimal performance in 10 Gb/s and higher short‑reach applications, verify transceiver compatibility with OM3 multimode fibre and follow manufacturer guidelines for maximum cable lengths.
