Abstract: Apparatuses and methods are described for generating an optical signal in an optical network. The apparatus comprises at least a first and a second laser configured to generate a first or second series of optical pulses respectively and a polarization beam combiner (PBC). The PBC is configured to receive the first and second series of optical pulses. Each optical pulse in the first series of optical pulses is received with a first state of polarization (SOP), and each optical pulse in the second series of optical pulses is received with a second SOP.
