I have a solution to implement and connect 2 MDS 9509s. Distances involved in fibre runs are sub 150m. Is there any benefit in me using 50/125 instead of 62.5/125 within these distances. The existing infrastructure would dictate that we run with 62.5/125. We may want to run with up to 10Gb over the Fibre, but as this will be aggregated through port channels I don't see the fibre choice as being an issue so long as we don't interface 62.5 with 50 directly... Can anyone confirm that this is ok?
