Nokia revealed on Wednesday that Indonesian digital infrastructure provider Solusi Sinergi Digital (a.k.a. Surge) has deployed its subsea optical solution in a new subsea fibre network connecting Jakarta and Singapore.

The new subsea network – which utilizes Nokia’s 1830 PSS – is designed with an initial capacity of 20.8 terabits, which Nokia said will enable Surge to offer connectivity services of up to 800GE for Tier-1 and Tier-2 enterprise customers.

Nokia also said its subsea solution enables Surge to deliver scalable, space and power efficient transmission, which will support the operator’s growth plans.

Surge director Shannedy Ong said the subsea network between Jakarta and Singapore will boost regional data center interconnectivity and support its broader plan to expand affordable broadband access to 40 million households, across Indonesia, including underserved communities.

“With Nokia’s advanced optical transmission technology, we can efficiently scale our network to deliver reliable, high-speed, and affordable broadband to unserved and underserved communities across Indonesia,” Ong said in a statement.

“With Surge, we are building a high-performance network and providing solutions that will unlock new opportunities for growth across Indonesia,” added James Watt, senior VP and GM of optical networks at Nokia.

No information was available on when the Jakarta-Singapore cable will be ready for service as we went to post.

Domestically, Surge currently operates over 6,900 km of fibre-optic infrastructure along railway corridors with up to 64 Tbps bandwidth capacity. Its FTTH access network covers over 300,000 fixed broadband Home Connects with a takeup rate of more than 90%, with service packages offering speeds between 200 Mbps and 500 Mbps.

The Surge deal is Nokia’s second subsea optical announcement this week. On Monday, the vendor said its subsea optical solutions will power the Medusa Submarine Cable System owned by AFR-IX Telecom that aims to connect North Africa and Europe when it goes live later this year.

Nokia scaled up its optical portfolio in July last year after it struck a deal to acquire Infinera for US$2.3 billion.
