Summary of chapter 1
• The UK and the world is highly dependent on undersea communications cables.
• 97% of global communications are still transmitted via cables lying deep beneath the oceans.
• Today’s submarine network comprises an estimated 213 independent cable systems and 545,018 miles of fibre. • There is no alternative to using these undersea cables. Satellite technology cannot effectively handle the communications requirements of the modern digital economy and society.
• In a single day, these cables carry some $10 trillion of financial transfers and process some 15 million financial transactions.
