Not really sure what this video is for.. it isn't a review or an in depth test. It is just unpacking and plugging a media converter into a customer router (CPE) in prep for doing the reverse where I replace the CPE with a media converter on a FTTP/FTTH installation.

tp-link MC220L(UN) Ver 4. (Version 4) Gigabit SFP Media Converter
Part Number: 1706502030

Video shows the media converter, the power supply and voltage/amps, plugging in a SFP module and the lights on the media converter.
