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