<div>Great response. We used Champion optics because I wanted to bypass the active electronics on our DWDM network and drive the filter card directly from an SFP. Foundry (at that time) didnt offer ITU grid DWDM SFPs so got them from a third party and theyve
been working great for years.</div>
<div> </div>
<div> </div>
<div> </div>
<div>That being said, we are going to single fiber SFPs so we can build an overlay network for our upgrade and we will also be changing out our dual fiber transition cards for customer distribution to single fiber and NIDs. Purchased single fiber Brocade optics
for the GigE distribution lobes and a third party single fiber optic for each single fiber customer drop. Third party optics are ¼ the price and only affecting one customer. Any troubleshooting distribution lobes with TAC is all Brocade and 10 Gig backbone
XFPs (DWDM ITU Grid) is also all Brocade.</div>

<div>Folks,</div>
<div> </div>
<div>Thanks. I think it's enough evidence of no religion is involved in Brocades approach to transceivers. I am sorry about a bit of holy-war kindling.</div>
<div> </div>
<div>My two cents, though :)</div>
<div> </div>
<div>Of course it's a little too much pathos in that 'risk of beating a dead horse' talk.</div>
<div> </div>
<div>1. If your network uses up to ~few tens of transceivers, especially of different (and not that expensive) types and you buy them in order of few items a year, it's unlikely you want to invest in your own testing and calculating the fail rate of the modules
from a source you prefer. In this case I also find it a good idea to pay some extra to your gear vendor in order to shift all this to its shoulders. This is easier and even cheaper (if you count your real expense, not just the MSRP price of the optics).</div>
<div> </div>
<div>2. But if you need hundreds or thousands of them [each year], especially if you need some SPF types not shipped by your gear vendor, you can (and will) try to use as less as possible types of optics and do the testing and fail risk management yourself
in order to decrease costs. If only you don't want to be pissed off the market. And of course you want to chose the source from several ones (and use all the benefits of the competition). No religion, just business.</div>
