Telkom Indonesia enhances nationwide backbone network with Coriant technology


CORIANT, a global supplier of SDN-enabled end-to-end packet optical networking and DCI solutions, on Feb 24 announced that PT Telekomunikasi Indonesia, Tbk (Telkom) has deployed Coriant’s best-in-class coherent optical transport and universal switching technology as part of a nationwide upgrade to its fiber-based backbone network.

Completed at the end of 2016, the network modernization initiative will 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.

“We continue to transform our network infrastructure with cutting-edge technologies to provide the best digital experience for our customers,” said Telkom Backbone and Core Network Planning and Deployment deputy EGM Agus Subandrio.

“With growing demand for data in Indonesia and across the Southeast Asia region, Coriant’s advanced traffic grooming, switching, and transport solution will play a key role in our ability to cost-efficiently scale backbone capacity and deliver an uninterrupted quality of service under any network condition.”

The Coriant solution enables Telkom to seamlessly scale its DWDM infrastructure to 100G per channel without replacing existing transmission systems.

In addition to terrestrial 100G 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 100G optical channels across an unrepeatered and DCM-free subsea transmission distance of over 350 kilometres between Dumai and Dangas.

The Telkom nationwide upgrade project includes expanded deployment of the Coriant mTera universal transport platform to optimise service traffic and maximise utilisation of fibre assets as the network scales.

The mTera UTP is a flexible multi-service transport solution that supports software-defined universal switching, including OTN, Carrier Ethernet, MPLS-TP and SONET/SDH in a single, power-efficient system architecture.

To simplify capacity provisioning and efficiently manage service traffic across the multi-domain Coriant optical transport network, Telkom is using the Coriant Transport Network Management System (TNMS), a management platform that helps service providers reduce opex and capex expenses through sophisticated end-to-end network control, automated provisioning features, and advanced planning capabilities.

“Telkom remains a premier provider of fixed and mobile network services in the region, and we are pleased to help them address the challenges of backbone traffic growth with the latest innovations in our end-to-end packet optical transport solutions portfolio,” said Coriant executive vice president and chief commercial and marketing officer Tarcisio Ribeiro.
