‌Nokia has deployed 100G in Pakistan Telecommunication Company Limited's (PTCL) network to enhance the capacity and speed of its optical network for both domestic and international traffic.

The new transport network supports PTCL in providing faster and more reliable services to its subscribers, while reducing capital and operating costs. More than 200 million consumers and businesses will now have access to more reliable, superfast broadband services.

“We are committed to providing a world class network experience to our subscribers and this deployment is a significant step in that direction,” said Saad M Waraich, chief technology & information officer at PTCL.

“Nokia's state of the art optical network technology and their expertise will help us to differentiate our portfolio as we provide our business and consumer subscribers with faster and more reliable broadband and carrier services.”

PTCL is able to flexibly increase network capacity and efficiency with the software-defined network (SDN) capabilities of the Nokia optical solution. This allows the operator to meet surging traffic demands caused by the increasing use of high-bandwidth services and applications such as HD and 4K video by individuals, and cloud by webscale companies.

By using PTCL's extensive fibre footprint, Nokia’s DWDM network provides multi-path redundancy against multiple fibre cuts and ensures higher network availability SLAs. The set-partition quadrature phase shift keying (SP QPSK) modulation is utilised to efficiently cover very long distance links which offers excellent optical signal-to-noise ratio (OSNR) tolerance but also a 30% improvement in latency over PTCL network due to less regenerations.

Furthermore, the new optical network makes it easier to launch new services based on the ROADM reconfigurable optical add-drop multiplexers (ROADM) technology, which adds flexibility and agility to the network.

Danny Atme, head of the customer business team for Middle East growth at Nokia, added: “We are happy to see PTCL taking the lead role in enhancing the capacity of its network as the consumption of broadband continues to increase, along with acquisition of new customers. Our advanced optical network technology upgrades PTCL's transport network to meet the unpredictable data traffic growth cost efficiently.”
