Pakistan's PTCL has deployed a new 100G optical transport network in partnership with Nokia.
The Nokia DWDM network utilizes PTCL's extensive fiber footprint to provide multipath redundancy.
It will be instantly upgradeable to 200G and 400G per wavelength as demand dictates, and the software-defined network (SDN) capabilities of the solution will allow the operator to increase network capacity and efficiency.
The network also uses set-partition quadrature phase shift keying (SP QPSK) modulation technology to allow PTCL to cover very long distance links with improved signal-to-noise tolerance and latency.
Finally, the solution has been designed to allow for the easier launch of services based on ROADM (reconfigurable optical add-drop multiplexer) technology.
“We are committed to providing a world class network experience to our subscribers and this deployment is a significant step in that direction,” PTCL CTIO Saad M Waraich said.
“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.”
Nokia this week also announced it has secured a five-year contract to expand the 4G network capacity and coverage of another Pakistani operator, Jazz.
