you need solder the RX and TX pins

I had exactly the same problem.

1. I took my CH-341 programmer, switched it to TTL mode (set jumper to 2-3 pins)
2. I used flying probe for connect to tx/rx and power without soldering. See photos
3. I used a laboratory power supply to power the SFP module
4. Then used minicom on my mac to connect to SFP module via telnet: minicom -D /dev/tty.wchusbserial210
