Hello,
SFP ports on the TSW202 are designed to support fibre optic communication, allowing for long-distance connections without compromising speed or quality. The included SFP cages provide flexibility for connecting to different types of networks, including fibre optic connections.
Regarding compatibility of SFP modules with Teltonika devices, we have a wiki page listing modules that have been fully tested and confirmed to be compatible. You can find the list here: Compatible SFP Modules With Teltonika Devices.
Please let me know if you have any further questions.
Best Regards,
