[j-nsp] PE-1GE-SX-B vs PE-1GE-SFP

[michael.firth at bt.com]

In addition to this, as the PE-1GE-SFP has been supported since JunOS
6.3, it will work with any supported JunOS release.

Also, see

Basically this means that the old fixed optics PICs may not be supported
in new versions of JunOS. Hence I would strongly recommend going for the
SFP PICs if you can.
