## Summary description

Alcasa LW-903SC is a 3 m OS2 single-mode fibre optic cable with 2x SC connectors on both ends and a 9 µm core. The cable supports full-duplex transmission for long-distance, low-loss links in telecom, datacenter and enterprise network installations, patching and equipment interconnects.

## Long description

Alcasa LW-903SC is a 3 m single-mode fibre optic cable designed for OS2 applications. It features two SC connectors on each end and a 9 µm core diameter that enables low-loss, long-distance transmission. The cable supports full-duplex operation and is supplied with a yellow LSZH jacket suitable for indoor installations where reduced smoke and halogen-free emissions are required.
Advantages
The 9 µm single-mode core and OS2 grade glass provide low attenuation and stable signal performance over long runs. SC connectors on both ends ensure reliable mechanical mating and straightforward hot-swappable connections in patch panels and equipment. The LSZH jacket minimises toxic fumes and smoke in case of fire and is appropriate for data centres, telecom racks and indoor conduits. Full-duplex capability allows simultaneous bidirectional data transfer over the paired fibres, making the cable suitable for standard network links.
Suitable for
Telecom long-distance single-mode links
Data centre patching and inter-rack connections
Enterprise network backbone and equipment interconnects
Indoor installations requiring low-smoke, halogen-free cabling
Key specifications

Length: 3 m
Connector type: SC to SC (both ends)
Configuration: Full-duplex (paired fibres)
Jacket material: Low smoke zero halogen (LSZH)

How to use
Insert the SC connectors into compatible SC sockets on patch panels, transceivers or network equipment until they click into place. Ensure connector endfaces are clean and free of dust before mating to maintain low insertion loss and protect transceiver ports. Route the cable with gentle bends respecting minimum bend radius for single-mode fibre and secure it using cable management accessories to avoid strain on connectors.
Usage recommendations
Verify cleanliness of connectors with an inspection tool and use fibre-safe cleaning wipes or fluid when necessary. Avoid tight bends and excessive pulling force during installation; follow the equipment manufacturer’s guidelines for patch cord handling and the minimum bend radius for single-mode fibres. Store the cable coiled without sharp kinks and keep it protected from mechanical damage and sources of excessive heat.
