Well thanks for the info. p.s. i'm not trolling, i have done lots of troubleshooting - but was posting from my iphone so didn't have the info handy. It is all included below.
The fibre run is about 40Km point to point. There are other people already using it on their own frequencies at 10Gb so I know it works. While i'll admit my knowledge about DWDM stuff is not great, I do have plenty of experience in the routing and switching space - just not much with the long haul fiber stuff. Anyway here are some of the steps I have taken: We have tried to reverse the Tx/Rx already with no luck. Changed / removed the wavelength frequencies Reboot routers offline / online FPC. So the is tunable 10Gb optic supported in MX10 or not?

The light coming from that XFP is not within the visible spectrum. You can't see it BUT IT CAN DAMAGE YOUR EYE. Do not look into it! To be honest, I'm not sure your post isn't a troll! However, there are plenty of things that could be wrong with your installation. The Tx/Rx fibers could be reversed. You may be using the wrong wavelength for the underlying DWDM system. The fiber span may not be good enough for 10G -- are there other 10G waves working on it? 1G/2.5G waves? You might need amplification or chromatic dispersion correction equipment. Your XFPs could be bad. Maybe it's vendor fiber and it is not patched correctly? Perhaps you have in-building cross-connects which are not completed or are of poor quality? Who really knows? You have done zero basic troubleshooting steps. The reason why is (assuming you aren't a troll) you don't understand what you are doing. I think your project will be more successful if you find a local contractor to help you. This may sound rude, but you are not even working SAFELY at this point, let alone effectively. Get yourself some assistance so you can get the job done without damaging your eyesight or delaying your work. You probably need someone local to you, because there is a very big knowledge gap between what you've got (in this specific context) and what you might need to troubleshoot quickly and SAFELY. The mailing list can hand-hold you through it if you post more information and do a bunch of troubleshooting steps, but I wouldn't want to be on the phone with my dark fiber vendor going, "well, some guys on juniper-nsp told me to rent a light meter and I used it and can't see any signal from my other POP..." :-/ $0.02. Again, I apologize if my response seems rude, but you are going to harm your eyes! -- Jeff S Wheeler <j...@inconcepts.biz> Sr Network Operator / Innovative Network Concepts _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
