Straightforward solution is QSFP+ -> QSFP+. I cannot deploy MPO for policy reasons. Can I, though, get a 40G connection using the 10Gig ports and standard fiber cabling? I know that connector loss is an issue also. I am going approx. 25m, switch to panel to panel to switch w/ approx. 0.4db loss/connection. If I *can* use the 10G ports for 40G, would I have to bypass the two panels and do a direct connection, or will the aggregate insertion loss be acceptable for 25m patching through 2 racks? Sorry, a little out of my pay grade here - any help is greatly appreciated!
