</div>OEM's are only 1/4 the price, you're lucky, 10x is hardly unusual.<br>
<br>
Out of interest, has anyone *ever* had an optic compatibility issue (as<br>
opposed to say a laser dying or lockout) from one of the top-level<br>
vendors (ex, JDSU, Finisar) on decent vendor (Cisco, Juniper, HP,<br>
Extreme, etc.) kit?<br>
<br>
With the price differential I find it nuts that people would do<br>
differently in most cases, excluding 100g and some of the odder DWDM or<br>
high-power types, it's almost certainly cheaper to treat optics as<br>
consumables than try and get support for them, even a NOC staffer or<br>
logistics person probably costs more than $100/hour, and you've got a<br>
very good process if you can work your way with a vendor to giving you<br>
an RMA (and send the faulty one back) in less than an hour. Even a 40g<br>
QSFP doesn't multiply that by a huge amount.<br>
