Downstream traffic in active (top) vs. passive optical network. A passive optical network consists of an optical line terminal (OLT) at the service provider's central office (hub), passive (non-power-consuming) optical splitters, and a number of optical network units (ONUs) or optical network terminals (ONTs), which are near end users.
Sri Lanka Telecom PLC (Sinhala: ශ්රී ලංකා ටෙලිකොම්, romanized: Śrī Laṃkā Ṭelikom, Tamil: ஸ்ரீலங்கா டெலிகொம்), doing business as SLT-MOBITEL, is the national telecommunications services provider in Sri Lanka and one of the country's largest companies [3] with an annual turnover in excess of Rs 100 billion.
10G-PON (also known as XG-PON or G.987) is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s (gigabits per second) over dark fiber. This is the ITU-T's next-generation standard following on from GPON or gigabit-capable PON.
It is commonly used to implement the link to the customer (the last kilometre, or last mile) of fibre-to-the-premises services. [2] [3] GPON puts requirements on the optical medium and the hardware used to access it, and defines the manner in which Ethernet frames are converted to an optical signal, as well as the parameters of that signal.
Following the publication of 40 Gbps NG-PON2 in July 2015, standardization activities turned to higher speed PON. [4] In November 2016, the Full Service Access Network (FSAN) Group released the Standards Roadmap 2.0 which indicated the development of "future optical access systems" with peak transmission rates above 10 Gbps.

Research activities at the CTR, both fundamental and applied, mainly focus on technologies related to the ...
NG-PON2 (also known as TWDM-PON), Next-Generation Passive Optical Network 2 is a 2015 telecommunications network standard for a passive optical network (PON). The standard was developed by ITU and details an architecture capable of total network throughput of 40 Gbit/s, corresponding to up to 10 Gbit/s symmetric upstream/downstream speeds available at each subscriber.
