In some sticks, such as those based on Lantiq chipsets, the serial interface 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 four wires are to be soldered and the other pins removed. This makes the adapter compatible with a single serial combination.
- the use of a board to which the SFP molex is soldered, exposing the main SFP pins.
- a ready-made breakout board that already exposes all 20 SFP pins on 2.54 mm headers, if you'd rather not solder an SMD Molex connector yourself (see below).

If you want to make your own board, here are some ideas:

the components to be soldered are instead:
- 1x MOLEX SFP (like Molex-744410001 lcsc, farnell)
- 2x pinout 2x10 (like MINTRON MTP125-1210S1)
If you'd rather not solder an SMD Molex connector, a prebuilt and tested board is also available. It exposes all 20 SFP pins on 2.54 mm headers with RX/TX silkscreen, so you slot the module in and connect your USB-TTL adapter — no soldering required.
