A case against vendor-locking optical modules

I've asked the same question and got the answer that there is a REAL BIG
chip manufacture that was having huge system issue and told the vendor that
they were going to rip out all the manufactures routing / switching
equipment if they didn't get it fixed.

after the manufacture send engineering staff on site they found that the
problem was not the routers or switches but the SFP's that the Chip
manufacture had purchased.  After replacing the SFP's they had no problems.

So if you were the router manufacture you might also put in the
locks....... Just say'n

I hate it also, but I also really like a stable network.  I also know that
there are some OEM's for even Cisco that I have used in the past.

Just my two cents.
