Embodiment Construction
[0046] Figure 5 It is a schematic structural diagram of an optical depolarization multiplexing receiving device provided by an embodiment of the present invention. The system includes: an optical splitter 51 , a horizontal optical signal acquisition device 52 and a vertical optical signal acquisition device 53 . The optical splitter 51 is used to split the received polarization multiplexed optical signal into two same polarization multiplexed optical signals. The two polarization multiplexing optical signals respectively include a first polarization state optical signal and a second polarization state optical signal; the first polarization state optical signal is when the polarization state optical signal in the horizontal direction is transmitted to the optical splitter An optical signal: the second polarization state optical signal is an optical signal when the polarization state optical signal in the vertical direction is transmitted to the optical splitter. After the ho...

The present invention discloses a receiving apparatus, a sending apparatus, a system and a method for optical polarization division multiplexing. The receiving apparatus includes: an optical splitter, configured to: split a received polarization-multiplexed optical signal into two identical polarization-multiplexed optical signals, where the two polarization-multiplexed optical signals both include a first State Of Polarization (SOP) optical signal and a second SOP optical signal, and the first SOP optical signal is an optical signal when a horizontal-SOP optical signal is transmitted to the optical splitter, and the second SOP optical signal is an optical signal when a vertical-SOP optical signal is transmitted to the optical splitter; a horizontal optical signal obtaining apparatus, connected to the optical splitter and configured to separate the horizontal-SOP optical signal; and a vertical optical signal obtaining apparatus, connected to the optical splitter and configured to separate the vertical-SOP optical signal, which mitigates crosstalk of optical signals and improves performance of an optical transmission system for optical polarization division multiplexing.
Description
technical field [0001] The present invention relates to the technical field of optical depolarization multiplexing, in particular to a receiving device, a sending device, a system and a method for optical depolarization multiplexing. Background technique [0002] With the continuous enrichment and development of network applications, the main line bearer rate of the optical transmission network has increased from 10 gigabits per second (Gb / s), 40Gb / s to 100Gb / s. Moreover, the 100Gb / s optical transmission system will become the mainstream of the next generation optical network. [0003] At present, the optical transmission system with a line rate of 100Gb / s is mainly realized through a polarization multiplexing system. The polarization multiplexing system modulates two 56Gb / s data source signals at the sending end to two optical signals whose polarization states are orthogonal to each other, and then synthesizes the two optical signals into one polarization multiplexed signa...
