Hello,

I am using a fiber pigtailed laser with a panda fiber and connect with
an FC/APC to another panda fiber. Unfortunately I have a loss of about
4.5 to 5dB due to this connection. I have cleaned the fibers so I
guess the loss is because of two different diameters.
Here are my two questions:

1. How much power loss is tolerable in a connector? I am concerned
about generating two much heat and damaging the fiber.
2. Is it reasonable to have such a high loss due to two different
diameters in a panda fiber?

Thanks

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.
