Hi all,
The ENO Ag and cable are connected and music is playing. I have already tried it both ways (i.e., Ethernet cable vs. fiber cable) as recommended by @lalitk except that I am still running a very short Ethernet cable directly from the router to a Netgear switch prior to the 45-foot run to the area where my server and system are located. I do like the simplicity of not having the two additional converters and their power supplies in the chain but did not initially hear noticeable differences between the long run of Ethernet vs. the long run of fiber.
The ENO clearly operates at 100 mbs as the lights on my Bonn N8 show amber instead of green as they do without the ENO in the chain. Also, in order to use the fiber, I needed to change out my converters from MC200CM (1000 mbs) to MC100CM (100 mbs) in order for the ENO to successfully handshake with my server.
Regarding the ENO itself, I have not yet discerned what I would consider a noticeably significant difference in the sound of my system with or without the ENO in the chain. I will have fun listening this weekend and will report back.
