In some sticks, such as those based on Lantiq chipsets, the serial is exposed in the upper pins of the ONT, in order to read them there are two possibilities:

  • the use of an SFP molex (farnell) to which you solder four wires and remove the other pins, this makes the adapter compatible for a single serial combination
  • the use of a board to which the SFP molex is soldered, exposing the main SFP pins
