Scylla Subsea Cable System is an unrepeatered subsea cable system linking London and Amsterdam, with a cable of 211km in length and 96 fiber pairs.

Scylla Subsea Cable System is the first subsea cable system between the UK and the Netherlands since 1999.

Scylla Subsea Cable System is privately owned and operated by euNetworks, ready for service on September 9, 2021.

Key features of the Scylla subsea cable system include:

• A low loss network that is entirely new fibre deployment.
• The terrestrial backhaul networks utilise new low-loss Corning SMF28 Ultra G657. A1 fibre cables and three entirely new amplification sites for the two cable landings and intermediate repeater in the UK.
• With existing sites and backhauls built over 20 years ago, these new facilities eliminate the unreliability of old infrastructure and provide scalable and power-efficient amplification housing, with significantly reduced long-run power demands.
• Scylla is a non-hybrid 96 pair double-armoured sea cable, solely using Corning’s SMF28 ULL (ultra low loss) G654.C pure silica fibre; giving all customers the benefit of future-proofed ultra-low attenuation on the 211km unrepeatered system.
• This low attenuation is critical to achieving lowest cost per bit, directly driving greater bandwidth per fixed-cost transponder.
• As well as ensuring deeper burial naturally, and laying the cable with precision and less impact on the seabed, euNetworks has buried Scylla up to 3 metres deep, offering better protection against strikes both today and in the future.

euNetworks launched Super Highway 1 linking Dublin and London to Lowestoft in November 2019. 

Scylla is the second Super Highway linking Lowestoft to IJmuiden and then onto Amsterdam. Combined with euNetworks’ existing metro networks in Dublin, Manchester, London and Amsterdam, the Scylla subsea cable system enables any data centre to any data centre connectivity between all these metros.
