It features 12 OS2 G657.A1 singlemode fibres that support high-speed Ethernet, fibre channel, broadband, and backbone network applications over extended distances. With enhanced bend performance, it is ideal for structured fibre optic installations, data centres, FTTx deployments, and high-capacity networks where flexibility and reliability are essential.\nIts loose tube construction protects against moisture, temperature fluctuations, and mechanical stresses, helping to maintain reliable optical performance in demanding environments. The CST armour provides resistance to crush, impact, and rodent damage, making it suitable for installations where additional mechanical protection is required, including ducts, trays, and external environments. The LSZH outer sheath improves safety by reducing the release of smoke and corrosive gases during a fire, and its B2ca Euroclass fire rating offers a high level of fire performance and complies with the CPR for European building installations.\nIt is suitable for internal and external applications, and combines low attenuation, reliable signal integrity, enhanced bend resistance, robust mechanical protection, and good fire performance, making it an ideal solution for scalable fibre networks.","brand":"Prysmian","offers":[{"title":"8 Core","offer_id":54403379429722,"sku":"9-08-LT-CST-IX-B2CA-BK-DK","price":0.95,"currency_code":"GBP","in_stock":true},{"title":"12 Core","offer_id":54403379495258,"sku":"9-12-LT-CST-IX-B2CA-BK-DK","price":0.97,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1017\/2999\/3050\/files\/Prysmian_Singlemode_OS2_G657a1_Loose_Tube_Fibre_Cable_CST_Armour_B2ca_Int_Ext.png?v=1783602896","url":"https:\/\/networksdirect.co.uk\/products\/prysmian-singlemode-os2-g657a1-loose-tube-fibre-cable-cst-armour-b2ca-int-ext","provider":"Networks Direct","version":"1.0","type":"link"}
