Description

Technical Field

[0001] This invention relates to the field of optical communication technology, and in particular to an automatic adjustment device, method and storage medium for XGS-PON uplink signal data stream. Background Technology

[0002] XGS-PON belongs to the GPON (Gigabit Passive Optical Network) series. It is a technological evolution of XG-PON. Its uplink and downlink rates are symmetrical, both at 10Gbps. Compared with the asymmetric XG-PON, which has a downlink rate of 10 Gbps and an uplink rate of only 2.5 Gbps, the uplink rate is improved, and the user experience is greatly improved.

[0003] There is no unified standard for the XGS-PON optical modules used in existing XGS-PON OLT (Optical Line Terminal) equipment. The differences in driver chips used by different module manufacturers result in different module parameters. Typically, an XGS-PON OLT manufacturer's equipment can only be adapted to XGS-PON optical modules produced by its own manufacturer. If other optical modules of different specifications are used as replacements, the parameters of these modules will not be compatible with the high-speed signals such as XGS-PON, leading to problems such as incorrect packet registration, packet loss, and flow interruption. In short, the existing XGS-PON OLT has poor flexibility, which seriously affects the user experience. Summary of the Invention

The automatic adjustment module is used to measure the positional relationship between the SMA electrical signals, the SD control signals, and the RESET control signals of the optical module, and to automatically adjust the optical line terminal according to the positional relationship, so that the adjusted optical line terminal is adapted to the optical module.

[0043] In this embodiment, the registration module includes an XGS-PON optical line terminal 1, an optical module 2, multiple XGS-PON optical network units 4, and an optical fiber splitter 3. The input port of the optical fiber splitter 3 is connected to the XGS-PON optical network unit 4, and the output port of the optical fiber splitter 3 is connected to one port of the optical module 2 and the input port of the photoelectric signal control module, respectively.

When the computer program for the automatic adjustment method of XGS-PON uplink signal data stream is processed, it implements the steps of the automatic adjustment method of XGS-PON uplink signal data stream.

[0067] In summary, this invention provides an automatic adjustment device, method, and storage medium for XGS-PON uplink signal data stream. It filters the 1577nm uplink data stream optical signal using a 1577nm / 1270nm wavelength division multiplexer and filters the 1490nm uplink data stream optical signal using a 1490nm / 1310nm wavelength division multiplexer, retaining the 1270nm XGS-PON optical network unit uplink data stream optical signal. This signal is then converted into an SMA electrical signal. An FPGA automatic adjustment device measures the positional relationship between the SMA electrical signal, the SD control signal, and the RESET control signal of the optical module, and automatically adjusts the optical line terminal (OLT) based on this relationship. This allows the adjusted OLT to adapt to the optical module, enabling it to automatically adapt to optical modules with different parameters from different manufacturers, improving the flexibility of the OLT and thus enhancing the user experience.
