I'm pretty sure we need dedicated SFP+ for each DWDM wavelenght !?
We are planning to buy the DWDM MUX from Cisco and even them are selling dedicated SFP+ for each wavelenght.
Here is the info from the Cisco product we want to buy:
http://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_data_sheet0900aecd806a1c36.html
According to this document we cannot use DWDM for stacking EX-4200 switch over the fiber link because Juniper is not selling a per wavelenght SFP+ or XFP.
I think I have found another plan to do it. I have found a company that are selling Fiber-To-Fiber converter. So we could use standard SR XFP on the Juniper side, but then transfer them into a dedicated Cisco DWDM wavelenght. It's supposed to be protocol-less but I'm afraid the stacking protocol on the EX-4200 would not work with such a set-up.
Here is the link for that product:

Here is how we could do it:
The thing is I really dont know if this is going to work. I would really prefer go direct from the EX switch to the Cisco DWDM MUX.
Any help would be really appreciated !
