PT Telekomunikasi Indonesia, Tbk (Telkom) has deployed Coriant’s coherent optical transport and universal switching technology as part of a nationwide upgrade to its fibre-based backbone network. The network modernisation initiative is designed to improve the performance and increase the capacity of Telkom’s terrestrial and subsea optical transport infrastructure to meet growing demand for high-bandwidth mobile and fixed line services and applications.
The Coriant solution enables Telkom to scale its DWDM infrastructure to 100 Gbits/s per channel without replacing existing transmission systems. In addition to terrestrial 100 G bits/s backbone upgrades, the combination of the Coriant hiT 7300 Multi-Haul Transport Platform and Coriant CloudWave Optics coherent interface technology enables Telkom to further boost capacity on its JASUKA undersea cable, which provides high-speed connectivity amongst Java, Sumatera, and Kalimantan islands. Initial implementation includes operational deployment of sixteen 100 Gbits/s optical channels across an unrepeatered and DCM-free subsea transmission distance of over 350 km between Dumai and Dangas.
