Fiber-optic cable is connected to the optics block. It does not matter which one of the two cables is
connected to the receiver inlet (Rx). In a normal application another cable is connected to the RGB
light source. IR light source is used in special cases such as heavy steam environment or in an applic-
ation where exceptionally strong light is needed.
