Re: Patch panel solutions for 4x10GE breakout

We generally run a MTP/MPO12 cable to a breakout cassette a few racks down,
and that's where we split out all of the LC pairs. It keeps the mess away
from the routers/traffic generators.

So the newer equipment we are looking at uses QSFP+/MTP with 4x10GE
breakouts to deliver 10G.  We are not wiring these up to things in the same
rack, they will be going to patch panels and then elsewhere in a facility.
It could potentially get messy with the panels we have today so we are
looking at other solutions.  These are all SM LR connections using LC.
There are a lot of SM MTP to LC options since that’s the way most panels
are wired, but they typically have 6 duplex LC connectors per MTP and not 4
which isn’t very efficient in this use case.  I’ve seen others just use an
intermediate LC to LC panel and just wire the breakouts to those and then
jumper the other side elsewhere.

Anything else others have used?  The point of the solution is to keep the
wiring mess in front of or near the device to a minimum.

Thanks,
