Fig 3: Identifying Cover Caps

The information flows from white to red. The ray must always enter the white insert (ws) in the optical fiber (coupling, chamber 1) and exit at the red insert (rt) (coupling, chamber 2). The inserts cannot be separately changed! As soon as an insert is removed from a fiber optic module, the module should be exchanged.
