Lintas achieves 500Gbps per channel with PSE-V super-coherent solution

05 May 2023

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, Nokia’s PSE-V super-coherent solution will help Telin increase capacity by around 31% while lowering the total cost of ownership. The trial exceeded the quality benchmark set by Telin and recorded a fibre capacity of 11Tbps in the 2.2THz of optical fibre spectrum. In fact, Nokia and Telin recorded a capacity of 500Gbps per channel compared to 400Gbps 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.
