1. Bit-Interleaver for an Optical Line Terminal of an Optical Access Network, comprising
a memory reader, operable to receive and provide a number of M data streams assigned to respective optical network units, a space-time switch, which is
operable to read within one input cycle up to M respective bit-sets from said respective M data streams,and furthermore operable to switch within one writing cycle up to N bits of said data streams onto up to N respective output ports providing respective output vectors, N OR-function elements, each operable to determine within said one writing cycle respective single output bits based on one of said respective output vectors, N memory elements, each comprising at least L bit sub-elements having respective sub-element addresses, and each being operable to write within said one writing cycle a respective one of said respective single output bits into a respective one of its bit sub-elements,comprising furthermore a control unit, which is operable to control
the reading of said M data streams by said space-time switch, the switching of said bits by said space-time switch onto said output ports, and a choice of the writing addresses of said bit sub-elements,wherein said control unit is operable to choose said output ports and said writing addresses in dependence on
predefined data rates, predefined offset values, a maximum number B of bits within a bit-frame, and the number N, and the number L. |
