We have witnessed focused efforts by the Government of India on maximising the reach of broadband and enabling higher speeds in order to increase internet penetration. It has been Sterlite’s continuous endeavour to help build capacity in this direction. As a pioneering step, Sterlite has established a state-of-the-art Centre of Excellence at Aurangabad dedicated towards research on helping India meet the challenges of higher data transmission speed and capacity demands. Five core laboratories and an installation testing facility have enhanced Sterlite’s capabilities in the design and manufacturing of optical fibres and optical fibre cables to service the ever increasing global demand for bandwidth.

facilities at centre of excellence

Terabit Transmission Systems Facility
Sterlite Tech Transmission System Img1

This laboratory is equipped with state-of-the-art transmission technologies to test signal performance in long haul networks up to 2000 km length and can emulate any national or international size networks.

This laboratory provides quick validation of Sterlite's Optical Fibres in a wide variety of real life network configurations. Additionally, the laboratory is used in the development and testing of next generation optical fibres and cables.

FTTx Demonstration Centre

With the introduction and rollout of the Nationwide Optical Fibre Project by the Government of India, a new focus has emerged for broadband connectivity in the "last mile" – the piece of the broadband network physically connecting the end users to the internet. Whether it is connecting mobile towers for 4G access, or direct connectivity of homes and business, FTTX (Fibre to the "X") is expected to grow significantly in India, in line with the Government’s vision of a Digital India.

FTTX experience centre demonstrates an end-to-end rollout of the last mile network, from the telecom service provider's central office to the installation of the outside plant, and all the way into a user’s living room to the termination of an optical fibre at a consumer’s high-definition television set. This facility utilises GPON technology, while facilitating up to 2.5 Gigabits per second (Gbps) of downstream and 1.25 Gbps of uplink capacity.

Located in Silvassa, this lab comes fully equipped with the latest blowing/jetting, pulling and aerial cable installation facilities.
This significantly enhances our engagement with customers and enables strategic partnerships with our carrier customers, allowing us in further understanding their hassles.
This enables us to find innovative solutions for their technology and operational problems.
From pre-sales requirements discovery, to best installation practices to field qualification of new products, this facility at Silvassa positions Sterlite Technologies uniquely on the global footprint.


The lab carries out design of optical fibres and devices, characterization of optical fibres, and development of optical fibre devices. While the test set up includes state-of-the-art equipment to test and characterise Sterlite optical fibres. A high power damage characterization set up, nonlinear coefficient measurement set up for measuring multipath interference of short fibres, and a simulation facility for fibre design using various finite difference, finite element, and analytical solvers.

The Glass Technology Laboratory addresses the principal process-related aspects of optical fibre manufacturing from preform to its subsequent drawing into fibre.

This lab includes state-of-the-art equipment, primarily focusing on improvisation/new development of various processes to ensure that only the ideal processes are employed to produce the best quality glass – a precursor for the best quality optical fibre.

The Optical Fibre Reliability Laboratory consists of state-of-the-art equipment to judge the preform quality, measure various aging conditions of fibres, and perform various mechanical tests in order to guarantee cable lifetime of over 35 years.
