'Pakistan's first 800GB WDM system' launched for faster connectivity

The PTCL group, Pakistan's top integrated ICT provider, has achieved a major milestone by launching the country's first 800 Gbps per wavelength Super C+L Wavelength Division Multiplexing (WDM) system.

This advanced technology enables a data transmission capacity of 64 Tbps per fibre, with the potential to reach up to 96 Tbps, marking a significant step forward for Pakistan’s digital infrastructure, according to the company's statement.

Developed in collaboration with Huawei, the Super C+L system supports a broader optical spectrum of up to 12 THz, compared to the 4.8 THz provided by traditional systems.

It combines high-speed 800 Gbps per wavelength, ultra-wide Super C+L spectrum, and advanced Flexible Grid optical switching.

This breakthrough positions PTCL at the forefront of the country's digital transformation, preparing the network for future technologies like Fixed 5.5G (F5.5G) and enabling faster, smarter, and more efficient connectivity.

Jafar Khalid, the group's chief technology and information officer commented: "Our focus is on advancing cutting-edge technology while maintaining sustainability. This upgrade will improve service quality, lower latency, and enhance the overall user experience for both consumers and enterprises while reducing our environmental footprint."

"It will also help us manage the growing demand for data traffic across different customer segments with reliable, cost-effective solutions," he added.

Victor Zhou, President of Huawei's Optical Domain, stated: "We are proud to support PTCL in building this high-speed optical network, which will boost Pakistan's digital growth and sustainability efforts."

"It will strengthen data center connections, reduce carbon emissions, and set the stage for future advancements like F5.5G. This technology investment will underpin Pakistan’s digital economy for years to come,” added Zhou.

This successful collaboration between PTCL Group and Huawei marks a transformative moment for Pakistan's telecommunications landscape.

By leveraging cutting-edge optical technology, the ICT provider is paving the way for enhanced digital services, faster internet speeds, and a more connected society.
