Nokia and mobile operator Ooredoo Qatar have achieved a symmetrical 40 gigabit per second speed using Nokia's Time and Wavelength Division Multiplexing Passive Optical Network fibre technology in a trial in January.
Nokia's TWDM-PON technology is said to deliver four additional wavelengths, each providing 10 Gbps symmetrical speeds, eventually providing a total of 40 Gbps. The vendor said the enhanced speed will allow the operator to upgrade its networks from the existing gigabit PON at speeds up to 2.5 Gbps to XGS-PON with speeds up to 10 Gbps and in the future to TWDM-PON at speeds up to 40 Gbps. The TWDM-PON technology, also referred to as Next Generation Passive Optical Network 2 technology, was deployed over Ooredoo's existing single fibre network. Nokia said the overlay technology is capable of adding more capacity to existing networks.
