  • Optical line terminal and optical fiber access system with increased flexibility
    Patent number: 11451318
    Abstract: The present disclosure relates to an optical line terminal that can be used in an optical fiber access system based on passive optical networks. The present disclosure further relates to a PON system; in particular the optical line terminal can be configured such that colourless components can be employed in a PON system using the optical line terminal and such that wireless communication can be directly employed in a PON system.
    Type: Grant
    Filed: September 24, 2019
    Date of Patent: September 20, 2022
    Assignee: DANMARKS TEKNISKE UNIVERSITET
    Inventor: Pengyu Guan
  • Optical line terminal and optical fiber access system with increased capacity
    Patent number: 11444718
    Abstract: The present disclosure relates to an optical fiber access system based on passive optical networks. In particular the present disclosure relates to a PON system with increased capacity and a method for increasing the capacity in a PON system. One embodiment relates to an optical line terminal for a passive optical network, comprising at least one transmitter for generating a time division multiplexed (TDM) downstream optical data signal, a first time lens optical signal processor configured to convert the downstream TDM signal to a downstream WDM signal for distribution to a plurality of users, and at least one receiver for receiving and processing an upstream signal from said users.
