Optical Network Configurations

Interesting to see that you use an industrial solution

The Pi2 doesn't do gigabit Ethernet.

The MC220L is one of the very cheapest FMCs but does not negotiate between 100mb Ethernet and 1gb Ethernet (1000base-T).

You need an FMC which does -- you can reuse your SFP.

 

This: https://www.trendnet.com/products/gigabit-fiber-converter/TFC-1000MGA is an example, there are others.

I like this one.

For those addicted to overkill:

LGB5510A, 10-Gigabit Layer2+ Web Smart Switch - Black Box

I like the AC input, SFP ports and the small form factor!

I avoid 10gbase-T, that is, 10Gbe Copper. It requires much more power than optical, and more power means more noise. In copper as speed and distance goes up, power goes up significantly. Not so significantly for optical. Not only is 10g copper overkill in terms of bandwidth, I expect that the SQ would be worse (haven't actually tested but expect that). I use 10g and 1g optical.

 

If someone has actually tested this out, their SQ impressions would be helpful, but my approach has been to try and minimize power use and hence noise.

It contains SFP.
