Pakistan Telecommunication Company (PTCL) has deployed Nokia’s technology to expand the capacity of its 100G transport network to 200G optical network for both domestic and international traffic in the major cities of Islamabad, Lahore and Karachi.
PTCL becomes the first operator in Pakistan to deploy high-performance 200G 8 Quadrature Amplitude Modulation (QAM) in the country, an optical long-haul technology offering more capacity at lower cost.
The upgradation of its optical network allows PTCL to address the demands of bandwidth, enabling its enterprise and individual users in Pakistan’s largest cities to use high-bandwidth services and applications such as HD and 4K video.
# Nokia 1830 PSS allows service providers to deploy services to maximize network capacity and efficiency
# By using PTCL’s fiber footprint, Nokia Dense Wavelength Division Multiplexing network provides multipath redundancy against multiple fiber cuts hence ensuring higher network availability SLAs
# Reconfigurable Optical Add-Drop Multiplexers (ROADMs) technology helps service providers to meet an unpredictable increase in traffic
# 8-QAM increases spectral efficiency allowing service providers to maximize the available resources
In addition, the network upgradation allows PTCL to flexibly enhance network capacity with the Software Defined Network (SDN) capabilities of the Nokia optical solution. Further, the flexgrid technology allows PTCL to upgrade to 300G or 400G in the future over the same installed base.
“We have enhanced the existing capacity from 100G optical network to 200G to take care of the growing traffic in these cities. Nokia’s technology and expertise helped us to deploy 100G and enhance customer experience, so its 200G technology is also the right choice for expanding network capacity,” Saad Muzaffar Waraich, chief technology and information officer of PTCL, said.
“Our technology enables PTCL to differentiate its services based on quality. With our 200G technology, PTCL is now in a position to cost efficiently address the ever-growing demand for capacity,” Carlo Corti, director of the Optics Business Development, MEA, Nokia, said in a statement.
