Sri Lanka’s international backhauling network connecting main three cable stations to Welikada international hub

Sri Lanka will secure outstanding cross connecting with other cable systems

Sri Lanka’s National ICT solutions provider, Sri Lanka Telecom PLC (SLT) has gained a great opportunity: full landing status of SMW5 Cable Station in Matara, Sri Lanka aiming to be a key regional player by offering state-of-the-art global services provided through multiple international undersea cable systems that run through Sri Lanka. SLT’s International Backhaul Network consists of three main cable stations in Colombo, Mt Lavinia and Matara connecting to SLT’s international backhaul hub at the Welikada SLT premises. All these stations are well connected by OTN NW on which the transport will be based dedicatedly reserved international connectivity to any cable system runs through Sri Lanka. Through this project, multiple undersea optical fibre cable systems: SEA-ME-WE 5, SEA-ME-WE 4, SEA-ME-WE 3, Bharat-Lanka and Dhiraagu-SLT will be interconnected through a highly reliable and redundant very high capacity Fibre Optic Ring.

The company with this dedicated international backhaul will be exploring for more global business opportunities and business impact of this would be the use of the cable system for traffic termination in the country, cross connecting with other cable systems and enhancing capacity. Exploring such opportunities, SLT identifies the challenge of backhauling traffic through Matara Cable Station and routing through Colombo Cable Station because all other submarine cables systems and domestic operators are based in Colombo.

By considering the growing demand for international bandwidth in the country and exploring new opportunities, establishing scalable mesh protected, WDM international backhaul NW is vital. Backhauling Global Connectivity options have to maintain the highest level of Service Level Agreements (SLA) standards because it transports domestic as well as international traffic. Therefore, we are capable of providing scalable mesh protection to global operators.
