Could someone share their experience with using generic optics for DWDM applications?
Not sure what you mean by "generic optics"? If you mean manufactured by Joe's Optics and Fishing Bait company and sold on ebay for special low rates, then the question is: are you in a position to test these units in advance to the extent that you're going to be happy with their reliability? Otherwise why are you trusting your entire business to this? Personally, I'm not in that position, so I buy third party transceivers from a respectable vendor with good quality service. This works very well for me. Cheaper transceivers are only cheaper when you take their lifetime cost into account. If they have quality issues, or cause more downtime, or require more amplification, or cause mobo overheating issues due to poor thermal characteristics, or if you need to spend a lot of time testing and characterising the transceivers before deployment, then they are probably not going to be cheaper. I could buy these transceivers on ebay, but I don't want the hassle of having to deal with links flopping offline and transceivers burning out regularly. No doubt plenty of cheap white-label vendors are completely fine, but I'm not going to invest my time/money or anyone else's time/money in trying to find out which, because for my requirements it's cheaper to do this than to use ebay.
