Fibre Optic Cable Alcasa LW-S903LASA 3m

The Alcasa LW-S903LASA 3m is a single-mode FTTH fibre optic cable designed for reliable high-speed data transmission. Equipped with G.652D fibre and a 9 µm core diameter, this 3-metre cable provides standard single-mode performance suitable for indoor and patching applications. One end uses an LC connector and the other an SC connector to support interoperability between different terminal equipment and patch panels.

Advantages

This fibre optic cable offers low attenuation and stable signal quality typical of G.652D single-mode fibre, supporting long-distance and high-bandwidth links in access networks. The 3 m length balances flexibility and manageability for rack-to-equipment or wall termination connections. LC and SC connectors provide a mix of compact interface and widespread compatibility, while the 9 µm core ensures single-mode operation with minimal modal dispersion.

Suitable for

• FTTH indoor patching and subscriber drop connections
• Interconnecting patch panels, media converters, and optical transceivers
• Data centre and telecom closet horizontal cabling
• Testing and commissioning of single-mode links over short runs

Key specifications

• Fibre type: single-mode G.652D
• Core diameter: 9 µm
• Length: 3 metres
• Connector types: LC (one end), SC (other end)
• Application: FTTH, patching, optical interconnects
• Typical use: single-mode optical transmission for access and premises networks

How to use

Connect the LC end to equipment with an LC port and the SC end to devices or panels with an SC interface, taking care to align connectors and avoid forcing them. Before insertion, inspect connector endfaces for contamination and clean with appropriate fibre cleaning tools if necessary. Route the cable without tight bends, maintaining the manufacturer’s minimum bend radius to prevent increased attenuation or damage. Secure the cable in trays or clips to prevent strain at the connector interfaces.

Usage recommendations

Use appropriate dust caps when ports are not in use, handle connectors by the boot or connector body to avoid touching ferrules, and perform optical power or continuity tests after installation to verify link performance. For permanent installations, keep cable runs away from high-EMI sources and ensure service loops are provided for future re-termination.
