摘要： A method, a device and a system for sending and receiving client signals are provided. The method for sending includes: distributing, in round-robin mode, OTU data frames into which client signals are encapsulated to VLs, in which the number of the VLs is a common multiple of the number of lanes of an OTN encapsulating module adaptation interface and the number of optical module adaptation lanes; inserting VL alignment identifiers that carry VL serial numbers and position information to the VLs, in which the VL alignment identifiers are adapted to compensate a transmission rate difference among the VLs; distributing, in bit-by-bit interleaving mode, the data on the VLs with the inserted VL alignment identifiers onto the OTN encapsulating module adaptation interface; converting data on the OTN encapsulating module adaptation interface by bit onto optical module adaptation lanes; modulating data on the optical module adaptation lanes and transmitting the modulated data onto an optical fiber for transmission, so as to compensate a transmission rate difference among different data lines caused by OTN long-distance transmission.

摘要： A sending apparatus, detection system, and detection method of a lidar are provided, to exclude a false target from a plurality of targets. Frequency-sweep optical signals with different slopes are introduced, the frequency-sweep slopes of the different frequency-sweep optical signals are opposite in sign in a time period, and absolute values of the frequency-sweep slopes are not equal. For a plurality of real targets, coherent detection is performed in at least two time periods separately corresponding to the different frequency-sweep optical signals. A distance and a velocity of the real target that are obtained through calculation by using the different frequency-sweep optical signals do not change, but a distance and a velocity of the false target change. Therefore, the distance and velocity of the real target are determined by using a same coherent detection result of the plurality of frequency-sweep optical signals. This can exclude the virtual target without increasing detection time. In addition, even if an I receiver or a Q receiver is used, velocity ambiguity does not occur, and costs can be further reduced.

摘要： An optical signal processing method and an optical component (20) are provided. The optical component (20) may implement two completely symmetric optical paths. Insertion losses of the two optical paths do not vary as an input polarization state changes, and the two optical paths have a same delay, thereby implementing polarization independence of the optical component (20). Further, two optical signals can be processed by using only one polarization-sensitive optical component (21). On one hand, costs of a user are reduced. On the other hand, the optical component (20) is always in presence of light. Therefore, a controller can control a status of the polarization-independent optical component (21).

Each input port and each add port are respectively connected to one first polarizer, and each output port and each drop port are respectively connected to one second polarizer. A first end of the first polarizer is connected to a second end of the first polarizer, to form a loop including the first polarizer. A first end of the second polarizer is connected to a second end of the second polarizer, to form a loop including the second polarizer. There is an annular waveguide array between a loop L Ii and a loop Loj. There is a second annular waveguide group between the loop L Ii and a loop L Dk .

摘要： This application discloses an optical receiver, including an optoelectronic detector, a transimpedance amplification circuit, a single-ended-to-differential converter, an I/O interface, and a controller. The optoelectronic detector is configured to convert a received optical signal into a current signal, where bandwidth of the optoelectronic detector is lower than a system transmission bandwidth requirement. The transimpedance amplification circuit is configured to: receive the current signal and a first control signal, and perform transimpedance gain on the current signal based on the first control signal, to obtain a voltage signal, where a frequency response value of the current signal within first bandwidth is greater than that within the bandwidth of the optoelectronic detector, and any frequency in the first bandwidth is not lower than an upper cut-off frequency of the optoelectronic detector. The single-ended-to-differential converter is configured to convert the voltage signal into a differential voltage signal. The I/O interface is configured to output the differential voltage signal. The controller is configured to generate, based on the differential voltage signal, a second control signal that is used to control the transimpedance amplification circuit to perform transimpedance gain on the current signal. According to the optical receiver disclosed in this application, costs are reduced while received signal quality is ensured.
