Tolerable power loss in connector (heat generation)

There are only two reasons that you would have different diameter panda fibers; different wavelengths or switching between multimode and singlemode. In either case you could be loosing the power in the fiber not at the connection per say. You need to get a patchcord that is the same diameter as the laser one or you will always have this problem.

Heat generation is typically a problem for very high power, not typical communications signal levels. Are you using watts of power?

However you can blow up the ends if they are FC/PC connections. You get a little piece of dirt in there and you have one nice Fabry Perot cavity!! Does a lovely job of blowing the fiber ends up.

Hello

Meanwhile I found out that the fibers have a different NA(0.19 vs

Thanks

No they don't. You need someone who is a great splicer and has access to a high end splicer such as a Vytran. They can make a tapered core fuse when splicing the two ends together. (the places I used to deal with are now out of business so I can't help with that part of the problem) However, this will not totally solve your problem. There is a reason that the two fibers are a different size. You need to find out the wavelength for each fiber and if they are single mode or multimode. If you try and splice a 850 fiber to a 1550 fiber you will have problems even if you taper the cores together. The same with SM to MM. You will get loss into the cladding.
