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.
