Fibre optic cable Alcasa 2m ST/ST

The Alcasa 2m ST/ST fibre optic cable by Good Connections is a 2-metre multimode link engineered for high-speed data transmission. Constructed with OM3 multimode fibre and a 50 µm core diameter, it supports full duplex communication via ST connectors on both ends. The blue-sheathed cable provides a straightforward, industry-standard connection for networking equipment that requires reliable optical links over short to medium distances.

Advantages

This ST/ST fibre cable uses OM3 multimode fibre which is optimized for higher bandwidth and improved performance with short wavelength laser sources. Its 50 µm core allows efficient coupling with common multimode transceivers, and the ST push-pull bayonet-style connectors ensure quick and secure mating. The 2 m length balances flexibility and signal integrity for typical rack, patch panel, and device-to-device connections.

Suitable for (tasks / use cases)

• Connecting switches, transceivers and patch panels within wiring closets or data racks
• Short to medium range multimode optical links in enterprise networks
• Full duplex data transmission between compatible multimode devices
• Laboratory setups and test environments requiring standardized ST connectors

When it may not be suitable

This cable is multimode OM3 with a 50 µm core and uses ST connectors; it is not suitable where single-mode fibre is required for long-distance runs or for systems that require different connector types such as LC, SC, or MTP without adapters. It is also not intended for environments requiring specialized ruggedized or armored cabling for direct burial or extreme mechanical stress.

Key specifications

• Length: 2 metres
• Fibre type: OM3 multimode
• Core diameter: 50 µm
• Connector type (both ends): ST male
• Transmission: Full duplex
• Cable jacket colour: Blue

How to use

Inspect connector endfaces for contamination and clean with appropriate fibre cleaning tools before insertion. Align the ST connector bayonet tip into the adapter or transceiver socket, insert and twist the connector sleeve until it locks. Use the 2 m length to route the cable with gentle bends respecting the minimum bend radius specified by the equipment manufacturer. For removal, depress the sleeve and rotate to release the bayonet lock, then withdraw the connector straight out.

What to consider before purchase

• Confirm your equipment accepts OM3 multimode fibre with a 50 µm core
• Verify both ends require ST connectors or plan for compatible adapters
• Assess whether 2 m length is sufficient for your rack or patch layout
• Check environmental and mechanical requirements (indoor use, non-armoured)

Usage recommendations

For optimal performance, keep connector endfaces clean, avoid tight bends, and match the cable type to the transceiver specifications. Use fibre cleaning tools and dust caps when connectors are not in use to maintain signal quality.
