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.
