Rack enclosures enable global network infrastructure to expand

摘要

Some 98% of all intercontinental telephone calls, internet traffic, emails, messaging and private data traffic is carried as digital data by fibre optic cables laid by specialist ships across the world's oceans. Today's cables, typically 25mm in diameter and weighing some 1.5 tonnes/km, are a far cry from the first working cables, laid in 1853 and linking Great Britain with Ireland, Belgium and the Netherlands. Spellman manufactures ship-borne power feed equipment, PFE, used to power submarine fibre optic cable repeaters.
