Back in November 2014, SLT officially launched an 8 Terabit network. This was, at the time, a new generation high-speed national backbone network that was essentially a sprawl of 20,000km of optic fiber cables. The purpose of this was to upgrade the existing infrastructure to offer better reliability and connectivity speeds to both consumer and enterprise users of SLT.
2016 saw SLT’s infrastructure strengthening further via multiple undersea optical fiber cable systems such as SEA-ME-WE 5, SEA-ME-WE 4, SEA-ME-WE 3, Bharat-Lanka and Dhiraagu-SLT. The cables would come to Sri Lanka via a double landing station in Matara. This bumped up the overall connection speed to 48Tbps of global bandwidth, costing the company around LKR 5.2 Billion with the total investment for the project costing around USD 700 million.
SLT was also the first Telecommunications provider to test pre-5G technology in South Asia. Partnering with Huawei Technologies, they were able to carry out a successful field trial of Pre-5G LTE Advanced Pro technology.
Here, SLT was able to achieve a downlink speed of 855.9 Mbps in TD-LTE 2500MHz band. Further, with a latency of 5.5 milliseconds, They also beat the record at the time which was 15 milliseconds for existing LTE Advanced networks.
The latest addition to SLT’s infrastructure comes in the form of a data center. The current infrastructure of the SLT’s data centers has been undergoing a transformation. Initially conceptualized in February 2017, the Tier 3 Datacenter in Pitipana is almost nearing completion. This would connect multiple other data centers located in SLT headquarters and Welikada.
In case you were wondering, a Tier 3 data center has a N+1 redundancy level. This means that in the event of a component failure, at least one component (N) will have at least one independent backup component (+1).
In comparison to Tier 1 and Tier 2, Tier 3 offers a lower level of interruptions per year as well. The data center would be located in the newly proposed Tech City area which spans from the key town centers of Malabe, Athurugiriya, Kaduwela, and Homagama.
The SLT data center would have a capacity of 500 racks with the ability to expand when needed. Customers and those interested can hire racks as required in order to manage their capital expenditure and operational expenditure.
In terms of rental, according to SLT, the new Tier 3 Datacenter will be cheaper in comparison to customers having their own data centers. In addition, they would also provide knowledge about the data center and related areas. They would also bear all costs associated with space, protection, disaster recovery and management etc.
What does this mean for SLT users?
Well, new technology is usually a good thing and perhaps this too is no exception. With the Tier 3 Data center in place, consumer and enterprises both would have global connectivity with the aid of the national fibre optic backbone network and accompanying cloud platform.
SLT’s other data centres too would be interconnected by means of this national fibre optic backbone network. Both consumers and enterprise customers alike can experience stable, reliable and fast network connectivity. At least, that is the plan.
