The PTCL Group, Pakistan’s leading ICT provider, has launched the nation’s first 800 Gbps per wavelength Super C+L Wavelength Division Multiplexing (WDM) system. Developed in collaboration with Huawei, this advanced technology enables a data transmission capacity of 64 Tbps per fiber, with the potential to reach up to 96 Tbps.

The Super C+L system supports a broader optical spectrum of up to 12 THz, compared to the 4.8 THz offered by traditional systems, combining high-speed 800 Gbps per wavelength with advanced Flexible Grid optical switching. This milestone positions PTCL at the forefront of Pakistan's digital transformation, preparing the network for future technologies like Fixed 5.5G (F5.5G).

According to PTCL's CTO Jafar Khalid, this upgrade will enhance service quality, reduce latency, and support growing data demands while maintaining sustainability. Huawei's Victor Zhou emphasized the network's role in boosting digital growth and sustainability efforts in Pakistan.
