[c-nsp] WS-X6748-SFP input errors

[Flint, Chris]

Hi Tim,

Assuming you're running older fiber, you probably need mode-conditioning patch cords for LX over MMF.

We ran into this with LX4 optics over MMF... several closets worked correctly, but one in particular wouldn't link up.  We found this document and fixed the problem.

LX/LH on both sides. It's an intra-building run, couple of hundred
metres at most.

(It's LX over mmf as we  have standardized on LX optics. We're trying
to encourage the deployment of smf in our buildings.)
