The Bharat Lanka Cable System is a short bilateral submarine cable connecting India and Sri Lanka across the Palk Strait corridor. Spanning 325 km, it links the two neighboring countries and supports direct telecommunications connectivity between them. The system is one of the shorter submarine cable routes in the broader South Asian region.
In India, the cable lands at Tuticorine, a port city on the southeastern coast of Tamil Nadu facing the Gulf of Mannar.
In Sri Lanka, the cable lands at Mt. Lavinia, a coastal locality situated just south of Colombo on the western shore of the island.
The Bharat Lanka Cable System is jointly owned by Bharat Sanchar Nigam Ltd. (BSNL) and Sri Lanka Telecom. BSNL is India's state-owned telecommunications operator, while Sri Lanka Telecom is the principal government-linked telecommunications provider of Sri Lanka. The two national carriers together hold the system under a bilateral ownership arrangement.
The cable entered service in 2006 and remains an operational link between its two landing points.
The India–Sri Lanka corridor is served by several other submarine cable systems, though the Bharat Lanka Cable System is substantially shorter and more geographically focused than its peers. Systems such as SeaMeWe-6 (21,700 km, expected ready for service in 2026), Asia Africa Europe-1 (25,000 km), and the Europe India Gateway (15,000 km) all reach India as part of long-haul intercontinental routes. The Bharat Lanka Cable System, by contrast, is dedicated entirely to the bilateral connection between the two neighboring countries, making its scope and role distinct from those larger systems.
Performance measurements over the last 60 days, based on 65 ping tests conducted through this cable, show an average round-trip latency of 41.7 ms, with a best recorded result of 15.5 ms. These figures are consistent with a short regional route of 325 km.
By directly connecting Tuticorine in India and Mt. Lavinia in Sri Lanka, the Bharat Lanka Cable System provides a dedicated bilateral telecommunications pathway between the two countries. With only two landing points and a focused geographic scope, the cable serves the specific connectivity needs between the Indian and Sri Lankan networks operated by its two state-affiliated owners.
