[j-nsp] Sources for SFP+ optics

[Bill Blackford]

When you evaluate third-party optics, do a complete test of them.

Look at light levels, push traffic through them, etc.

Several manufacturers, like Finisar, MRV, etc. send the units that
test well to Juniper, Cisco, etc. The ones that don't pass well, go to
third-parties. Alos, if they are surplus and used, they could be
dirty.

We've recently been burned by using third-party. The initial evals
tested fine, but the last order had a 50% failure rate.

Good luck.
