In my opinion this is the main problem. 100Base-LX interface type is
used very often these days and the number of LX10 SFP needed is not
high. It should not be a problem to buy a few more expensive SFP from
authorized source. But it has to be 100Base-LX10. Workaround with using
GE SFP it's not feasible in my case.

That is exactly, what I did. My supplier provided me a SFP with nice
blue sticker "Juniper Compatible". Unfortunately, I couldn't force the
interface to be up, even with external fiber loop on the same module
(TX2RX). The manufacturer of that module was GBC Photonics
(SF-SM31020D-01G-GP).

Can you tell what exactly type of MX-series line card and what was
exactly manufacturer and P/N of SFP you used with 100Base-LX10 ? In my
case it was: MIC 3D 20x 1GE(LAN) and SFP as mentioned above.

especially when I don't have another choice.
