EllaLink announced Tuesday the development of a direct connection between Sines and the Lisbon Metro Area – the Olisipo submarine cable system, an unrepeatered 110km submarine cable, with 144 fiber pairs and an impressive total design capacity of 4.3 Petabits.

The Olisipo system is designed to connect all the international submarine landings in Portugal with the major Data Centres in the region with a secure multi-petabit future-proof infrastructure.

Ellalink unveiled earlier in June to build a submarine cable connection between Sines and Lisbon. By creating a domestic subsea system, EllaLink is reinforcing Portugal's interconnectivity ecosystem. And it is now naming the planned Sines-Lisbon cable Olisipo.

This Olisipo submarine cable will land in Carcavelos and Sines and will be ready to branch into Seixal & Sesimbra cable landing stations and connect the Setubal area. Incorporating 288 fibers (144 fiber pairs), the unrepeatered 110km fully buried cable will have an impressive total design capacity of 4.3 Petabits. Additionally, the cable robustness will be enforced by particular care given to route engineering with special attention to cable crossing, full subsea and terrestrial burial strategy, full cable armouring and extra shore-end protection with bore pipe in Sines.

The Olisipo cable system will provide direct POP to POP connectivity at fibre pair level between the main Data Centres located in Sines and Lisbon Metro Area, connecting at day one the datacentres of Start Campus in Sines and Altice LDV in Lisbon.

EllaLink considers Sines as one of the most important interconnection Hubs in Iberia. The EllaLink submarine cable system enables the only high-capacity and direct connections between Europe and South America, landing at the EllaLink Vasco da Gama CLS in Sines. Connecting and transporting traffic between Brazil and Portugal, onwards across Europe and ultimately across the globe is the primary role of the EllaLink cable system and the data centres it connects to! 

The new petabits cable connecting Sines and Lisbon together which will be able to compete with major European hubs as both cities are being seen as a preferable gateway to Europe already.

Olisipo is projected to be ready for service in 2024.
