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. One embodiment relates to an optical line terminal for a passive optical network, comprising at least a first transmitter for generating a time division multiplexed (TDM) optical carrier signal, said first transmitter comprising a first time lens optical signal processor configured to convert the TDM optical carrier signal to an wavelength division multiplexed (WDM) optical carrier signal for distribution to a plurality of users / ONUs, at least a second transmitter for generating a wavelength division multiplexed (WDM) downstream optical data signal for distribution to said plurality of users / ONUs, and at least one receiver for receiving and processing an upstream signal from said users.
