Reading Module thresholds with real-time digital diagnostics on the CodingBox

      CodingBox Cloud Editor is a code reading/writing tool developed and produced by ModuleTek, which is used with EzCoding program. It has the advantages of lightweight and simple operation, and can provide users with the functions of opening/saving code files, reading/writing codes to modules, MSA parsing of read codes, reading module thresholds and real-time digital diagnosis. Optical module digital diagnosis is an important parameter to judge the performance of the module, users can use CodingBox cloud editor to quickly view the module threshold and real-time digital diagnosis, the following introduces how to read module threshold and real-time digital diagnosis on CodingBox:
      I. Information/Material Preparation
      1. CodingBox Cloud Editor;
      2. EzCoding program (download from http://www.sfpcodingbox.com/Download.html );
      3. One module (SFP-10G-LR module is used in this case);
      4. fiber optic patch cords (this case uses single-mode fiber);
      5. computer;
      II. the operating steps
      1. test environment preparation:
      ① Use the USB cable to connect CodingBox and the computer, under normal connection, the upper-left corner of the indicator is green, red number shows "1".
      ② Insert the module to be tested, LR, into the SFP port of CodingBox, and use single-mode optical fiber to connect the transmitter and receiver of LR.

      2. Start the EzCoding program:
      ①When there is no module inserted into CodingBox, the TextBoard on the left side of EzCoding program shows blue color and identifies "NONE".
      When there is no module inserted into CodingBox, the left side of TextBoard of EzCoding program shows green color and identifies the inserted module type as "SFP"; WorkType is positioned as "SFP" by default.

      3. Introduction of DOM reading interface functions (this interface will be displayed only when the module is inserted into EzCoding):
      ① Module Threshold Range: According to the threshold value written in module A2LOW area, it automatically converts and displays the threshold range of temperature, voltage, current, transmitting optical power and receiving optical power;
      ② real-time digital diagnostics: the program default check "Sequence Read (continuous read)", the program reads DOM real-time data, you can also choose to remove the check box for continuous read, click on "Read DOM" for a single read DOM values The default unit of optical power is uW, you can switch the unit of optical power to dBm by checking "Unit dBm";

      4. Insert the module into the Huawei switch, and use the switch terminal to read the threshold value of the module, which is the same as the threshold value of the module read by the EzCoding program in CodingBox:
