Nokia has announced the results of a trial conducted last year over a 3,551 km subsea cable between Jurong in Singapore and Manado in Indonesia – and they are pretty impressive.
Nokia and PT Lintas Teknologi Indonesia (Lintas) successfully conducted a trial of Nokia’s next-generation PSE-V super coherent optics on PT Telekomunikasi Indonesia International (Telin)’s Indonesia Global Gateway’s (IGG) submarine live network.
When deployed, says Nokia, its PSE-V super-coherent solution will help Telin increase capacity by around 31% while lowering the total cost of ownership.
Indeed, the company says the trial exceeded the quality benchmark set by Telin and recorded a fibre capacity of 11Tb/s in the 2.2THz of optical fibre spectrum. In fact Nokia and Telin recorded a capacity of 500 Gb/s per channel compared to 400 Gb/s per channel of the existing equipment.
Powered by second-generation probabilistic constellation shaping (PCS) technology with continuous baud rate adjustment, the Nokia PSE-V super coherent chipset ensures optimal use of spectrum and helps service providers reduce cost per bit.
The trial utilized Nokia’s 1830 Photonic Service Switch (PSS) for wavelength division multiplexing (WDM) and repeater loading, and the 1830 Photonic Services Interconnect – Modular (PSI-M) compact modular platform for PSE-Vs transponder cards, enabling Telin to further improve spectral efficiency on its subsea cable systems, including repeaters.
Telin is the international arm of Telkom Indonesia, the largest Indonesian network provider. Its coverage includes 27 submarine cables, totalling more than 250,140 km in length, and 58 points of presences in 26 countries.
