description

Connectable hermetic feedthroughs inherently induce insertion losses which can rule them out of some applications where photon budget is tight.
In that case products without fiber discontinuity are to be considered.
According to the level of hermeticity required the sealing of the fiber will be different.

Besides the usual optical parameters leading to the choice of fiber, it will be important to consider the followings :

Material
Mechanical design
Hermeticity needed
Environment
Length of fiber
Connectors to be used
