## Summary description

The Alcasa 20m ST/ST fibre optic cable features OM4 fibre type with a core diameter of 50 µm, ensuring high-speed data transmission. It supports full duplex communication, making it ideal for networking applications. With durable ST connectors on both ends, this cable provides reliable connections for your devices, enhancing performance and reducing latency.

## Long description

The Good Connections Alcasa 20m ST/ST fibre optic cable is a 20-metre duplex patch cable with OM4 multimode fibre and ST connectors on both ends. Designed for high-speed data links, the cable uses a 50 µm core diameter multimode fibre that supports increased bandwidth and reduced modal dispersion compared with lower-grade multimode types. The ST/ST termination provides a bayonet-style connector suitable for many networking panels, media converters and optical transceivers, ensuring stable physical and optical contact for full-duplex communication.
Advantages
This Alcasa fibre optic cable delivers consistent signal quality over its 20 m length thanks to the OM4 multimode core, which is optimised for high data rates and short to medium distance links. The cable assembly includes durable ST metal housings that resist wear from repeated insertion and removal. With full-duplex capability, the cable supports simultaneous two-way transmission and reduces latency in networked systems. The jacket and internal buffering are designed to protect the fibre from physical stress and maintain performance in typical rack or conduit installations.
Suitable for
Patch panels and backbone links in data centres and server rooms
Connecting switches, media converters and optical transceivers
Short to medium distance multimode links in campus networks
High-bandwidth applications such as storage area networks (SAN) and virtualization environments
Key specifications
Fibre type: OM4 multimode
Core diameter: 50 µm
Length: 20 m
Connector type: ST on both ends (duplex/ST–ST)
Transmission: full-duplex multimode
Typical use: indoor network patching and device interconnects
How to use
Install the Alcasa 20m ST/ST cable by aligning the ST connector’s bayonet locking sleeve with the receptacle on the device or panel and twisting until it locks. Use one fibre per direction to maintain full-duplex operation. Route the cable to avoid sharp bends and excessive tension; observe the manufacturer’s minimum bend radius for multimode fibre. For best optical performance, keep connector endfaces clean and inspect with appropriate cleaning tools or inspection equipment before insertion. When removing, unlock by twisting the ST sleeve counterclockwise and pull straight out to avoid damaging the connector.
Usage recommendations
Store and handle the cable in protective packaging before installation to prevent contamination of endfaces. For installations in high-density racks, label both ends to simplify identification and testing. Perform an insertion loss check or continuity test after installation to verify link performance and ensure the OM4 fibre meets the required optical budgets for your network equipment.
