US 2026/0238349 A1 · OPTICAL INTERCONNECT SYSTEM WITH OPTICAL PILOT ASSISTED RECEPTION

Abstract

The present invention discloses an optical interconnect system (100) with an optical pilot-assisted reception receiver (130). The system (100) includes at least one transmitter (110) including at least one multi-wavelength laser source (111) configured to emit light with a plurality of wavelengths, at least one optical modulator block (112) connected to the multi-wavelength laser source (111), where the optical modulator block (112) is configured to split the received carriers into two polarization channels corresponding to light in the two orthogonal polarization components, and at least one polarization multiplexer (P-Mux) (113) connected to the optical modulator block (112), where the P-Mux (113) combines at least one independent modulated signal and at least one optical pilot at different wavelengths from the two polarization channels into a polarization-multiplexed signal, and at least one optical channel (120) to transmit the polarization-multiplexed signal from the transmitter (110) to the receiver (130).
