Since there are various signals in the reflected signal, in this embodiment, it is determined whether the received reflected signal is a reflected signal (i.e., a target loop signal) of an optical signal transmitted in a (first) data channel of the Optical Network Terminal (ONT) and the optical splitter by detecting the wavelength of the received reflected signal, specifically, the (first) wavelength of the received reflected signal is determined, and the (second) wavelength of the optical signal transmitted by the Optical Network Terminal (ONT) at a time closest to the current time (i.e., the target time) is obtained, and it is determined whether the received reflected signal is a reflected signal (i.e., the target loop signal) of an optical signal transmitted in a (first) data channel of the Optical Network Terminal (ONT) and the optical splitter by comparing the two wavelengths (first wavelength and second wavelength). Wherein if the (first) wavelength of the received reflected signal is equal to the (second) wavelength of the optical signal transmitted by the Optical Network Terminal (ONT) at a time closest to the current time (i.e. the target time), it is determined that the received reflected signal is not the target loop signal; if the (first) wavelength of the received reflected signal is equal to the (second) wavelength of the optical signal transmitted by the Optical Network Terminal (ONT) at a time closest to the current time, i.e. the target time, and there is also an optical signal in the set of target wavelengths equal to the (first) wavelength of the received reflected signal, it is determined that the received reflected signal is the target loop signal. The target wavelength set is used for recording the wavelengths of optical signals sent by the optical splitter to each Optical Network Terminal (ONT), and the number of the recorded wavelengths in the target wavelength set is the same as the number of the Optical Network Terminals (ONTs) in the optical fiber network.
According to an alternative embodiment of the present application, the target set of wavelengths is obtained by: determining target distances between each optical network terminal and an optical line terminal to obtain a plurality of target distances; determining a third wavelength of an optical signal sent by an optical line terminal at a target moment, determining a difference value between each target distance and the third wavelength to obtain a plurality of difference values, and determining the ratio of the plurality of difference values as a proportional array; and determining fourth wavelengths of optical signals received by each optical network terminal according to the proportion sequence to obtain a plurality of fourth wavelengths, wherein each fourth wavelength has an inverse proportion relation with each difference value, and the plurality of fourth wavelengths form a target wavelength set.
In this embodiment, the inverse proportional relation between the wavelengths of the optical signals transmitted between each Optical Network Terminal (ONT) and the (first) data transmission channel between the optical splitters is determined according to the distance between each Optical Network Terminal (ONT) and the optical splitter, the wavelengths of the optical signals transmitted by the optical splitter to each Optical Network Terminal (ONT) are determined, and a target wavelength set is generated.

In this embodiment, it may also be determined whether the received reflected signal is a reflected signal (i.e., a target loop signal) of an optical signal transmitted in a (first) data channel of an Optical Network Terminal (ONT) and an optical splitter by determining the frequency of the received reflected signal. Specifically, first, the (first) frequency of the received reflected signal is determined, and at the same time, the (second) frequency of the optical signal sent by the Optical Line Terminal (OLT) to the optical splitter at the target moment is obtained, and by comparing the two frequencies (i.e., the first frequency and the second frequency), it is determined whether the received reflected signal is the reflected signal (i.e., the target loop signal) of the optical signal transmitted in the (first) data channel of the optical splitter and the Optical Network Terminal (ONT).

In some embodiments, the optical fiber networking in which the detection method of the optical splitter in the embodiments of the present application is applied includes an erasing device, where the erasing device is installed at a monitoring port of the optical splitter and is used to detect whether there is an image signal of an optical signal emitted by an Optical Line Terminal (OLT) in a signal to be reflected by the reflecting device, and if there is the image signal, the erasing device retransmits a reflected signal without the image signal.
According to further alternative embodiments of the present application, the reflecting device, before transmitting the reflected signal, further comprises: acquiring a state identifier of the light splitter, and taking a value of the state identifier; transmitting a reflection signal to the optical line terminal through the reflection device under the condition that the value is an effective value; and after the reflecting device transmits the reflected signal, assigning the value of the state identifier to an invalid value, wherein the invalid value indicates that the reflecting device stops transmitting the reflected signal.
In this embodiment, before the optical splitter transmits the reflected signal through the reflecting device, the state identifier of the optical splitter is first valued, and whether to transmit the reflected signal is determined according to the value of the state identifier. The reflecting device confirms whether the value of the state identifier of the optical splitter is a valid value (e.g. 1), if the value is a valid value, the transmission of the reflected signal is allowed, at this time, the reflected signal is transmitted to the optical splitter, if the value is not a valid value (e.g. 0), the reflected signal is transmitted before the detection is performed, and therefore, the transmission of the reflected signal is stopped.
By the steps, whether the optical splitter exists in the optical fiber networking or not can be judged only by the optical signals reflected by the reflecting device.
