The simplest form of the fiber-optic patch cord is a single strand of optical fiber surrounded by a buffer and protective jacket with connectors at both ends.The optical fiber core diameter and its numerical aperture (NA) define the coupling efficiency into the fiber. The most popular optical fiber core diameters for optogenetics and fiber photometry experiments are those with 200 µm and 400 µm core diameters. As for the numerical aperture of the fiber, smaller 0.22 NA is suitable for laser light sources, while for incoherent light sources, like LEDs, it is recommended to use 0.5 NA and higher all the way from the light source to the sample.
