Prysmian 48 Core Singlemode OS2 G657a1 Multi Loose Tube Cable CST Armour LSZH Ext - Black

The Prysmian Singlemode OS2 G657.A1 Multi-Loose Tube Cable CST Armour, LSZH, Eca, External delivers reliable, long-distance data transmission across campus, enterprise, telecommunications, and outdoor network installations. It features OS2 G657.A1 singlemode fibres that support high-speed Ethernet, fibre channel, and broadband applications over long distances. It has enhanced bend performance, making it ideal for backbone networks, data centres, metropolitan networks, FTTx deployments, and high-capacity external fibre optic infrastructure.

The multi-loose tube construction protects against moisture, temperature fluctuations, and mechanical stresses while accommodating high fibre counts for efficient fibre management. The CST armour provides resistance to crush, impact, and rodent damage, making the cable suitable for demanding outdoor environments and direct burial applications. The LSZH outer sheath improves fire safety by reducing the release of smoke and corrosive gases during a fire, while the Eca Euroclass fire rating ensures compliance with the CPR.

It is designed for external use and delivers robust, long-term performance in ducts, direct burial installations, trays, and other outdoor environments where enhanced mechanical protection is required. The durable construction maintains reliable optical performance under a variety of conditions while remaining straightforward to install and it combines low attenuation, reliable signal integrity, enhanced bend resistance, high fibre capacity, and mechanical resilience, making it an ideal choice for scalable, future-ready outdoor fibre optic networks.
