The capacity of Bangladesh’s only international submarine cable connection has been upgraded to 85Gbps from 40Gbps, but the new bandwidth cannot yet be utilised because the backhaul link from the landing station to Dhakar has not received the necessary upgrades, local newspaper The Daily Star reports. Monwar Hossain, managing director of Bangladesh Submarine Cable Company Ltd (BSCCL), said the capacity of the undersea fibre-optic link to the SEA-ME-WE-4 submarine cable will reach 200Gbps by September this year, while the active capacity of the terrestrial backhaul route from Cox’s Bazar to the capital is currently 30Gbps, with a total useable capacity of 40Gbps, according to officials at state-owned Bangladesh Telecommunications Company Ltd (BTCL). The telco’s board in November approved a 200Gbps upgrade to the backhaul link, but this has been delayed, and a recent BTCL board meeting observed that if the state-run firm does not carry out the work itself, the additional bandwidth may be provided by other, newly licensed terrestrial cable operators, decreasing BTCL’s revenue. A BTCL committee stated that the national operator currently earns BDT190 million (USD2.3 million) via the backhaul link, which it could increase to BDT320 million within two years as data and voice traffic increases. Azizul Islam, managing director of BTCL, said the company has already started work to upgrade the link.
