摘要： Proposed is a method of optical data transmission. The method comprises different steps. A first optical signal and a second optical signal are generated, such that the optical signals possess a same wavelength, respective phases, which are modulated in dependence on respective data values, and respective polarization states, which are essentially orthogonal to each other. A combined optical signal is generated, by combining the optical signals, such that the combined optical signal possesses a polarization state with a predetermined variation. The combined optical signal is transmitter over an optical transmission line and received. Two time-discrete sampled signals are generated, by sampling the received optical signal along two orthogonal polarization planes. Two filtered signals are generated, by filtering the time-discrete sampled signals in the time-discrete domain, using a function that is indicative of the respective predetermined variation. Finally, respective data values are derived from the filtered signals.

摘要： Proposed is an optical node that contains a number of A optical demultiplexers. Each demultiplexer is adapted to provide at its N output ports N incoming optical signals received from N optical cores of an incoming optical multi-core fiber. Furthermore, the optical node contains a number of B optical multiplexers. Each multiplexer is adapted to receive at its N input ports N outgoing optical signals and to insert the N outgoing optical signals into N optical cores of an outgoing multi-core fiber. The optical node is configurable to switch one of the incoming optical signals simultaneously onto B input ports of different multiplexers and to combine A of the incoming optical signals from A output ports of different demultiplexers onto a same input port of one of the multiplexers. Alternatively, N incoming signals are received from N different mode signals of a spatially multiplexed multi-mode fiber and then transmitted as N multi-mode signals into a spatially multiplexed multi-mode fiber.

摘要： Proposed is a method of demodulating a phase modulated optical signal received from an optical channel. A time-discrete electrical signal is derived from the phase modulated optical signal, using a local optical signal, which has a frequency that is essentially equal to a carrier frequency of the phase modulated optical signal. A phase error between the local optical signal and the phase modulated optical signal is compensated, by deriving from the local optical signal a phase offset and modifying the derived time-discrete electrical signal by this phase offset. A chromatic dispersion caused by the optical channel is compensated, by filtering the modified time-discrete electrical signal using a digital filter.

摘要： Proposed is a method of optical data transmission. A first data signal and a second data signal are received at a same sampling rate. A third data signal and a fourth data signal are generated, using the first and the second data signal, wherein the two data signals are delayed to each other by a delay time that is varied over time. The phase of a first optical signal is modulated in dependence on the third data signal, and the phase of a second optical signal with a same wavelength is modulated in dependence on the fourth data signal. The first optical signal is transmitted in a first polarization plane into an optical fiber, and the second optical signal is transmitted in a second polarization plane orthogonal to the first polarization plane into the optical fiber.
