Is this compatible with all sfp modules? And does it convert between Ethernet and fibre in both directions?

You need an ethernet compatible SFP, but given that it should work. I used random ones. Translation goes both ways, I guess that's in the nature of how ethernet works. I had a few of these die within a couple of years and hence am not too happy with them, but to be fair that nay have been due to the radiation environment we operated them in.

Is this tp link mm220l a version 3 or a version 4

Hi, It should be Version 4 now. Thanks.

what does this link actually do? will it increase download and upload speeds?

This product is a media converter. A media converter converts from one medium to another, in this case from fibre optic cable (which is typically the input to the house) to cat5 cable via an rj-45 connentor. If the fibre link speed is 10M then but the ethernet (cat5) network is 100M the you will be limited to 10M into the network from out of the house but the network will still be 100M. In short it will not in itself increase upload and download speeds. I had 100M fibre into my flat and converted this onto my internal 100M/1G cable network. It worked very well.
