摘要： Proposed is an OLT for a passive optical wavelength division multiplex network. The network contains optical transmitters for generating downstream signals of an L-Band, as well as optical receivers for receiving upstream signals of a C-Band. Furthermore, the OLT contains a bi-directional SOA and an optical interface. The optical interface, the SOA, the transmitters and the receivers are optically coupled such that an upstream signal received at the optical interface is firstly provided to the bi-directional SOA and subsequently from the SOA to one of the receivers, and such that a downstream signal generated by one of the transmitters is firstly provided to the bi-directional SOA and then subsequently to the optical interface. The bi-directional SOA has a gain function that is not constant with respect to a wavelength of an optical signal to be amplified. Furthermore, the gain function is maximal for a wavelength located within the C-band.

摘要： The invention concerns a method for improving signal transmission in a passive optical network. The method comprises balancing, by a network element (2), at least two optical signals (13a, 13b, 13c, 13d) by attenuating one or more of the at least two optical signals (13a, 13b, 13c, 13d). The invention concerns further the network element (2) and a software program product used to implement the method.
