Constructing the transmission path
A transmission path starts at a transmitter output and ends at a receiver
input.
The transmission path is made up of fibre-optics cables and fibre-optics
cable leadthroughs. These serve as, for example, coupling units for wall
leadthroughs.
The plug-in connectors correspond to FSMA standards (IEC 874-2).

Types of fibre-optics cables
Plastic fibre-optics cables can be used for transmission length of up to 50
m and glass fibre-optics cables for lengths up to 500 m.
There are three different types of fibre-optics cables:
Plastic fibre-optics cables for internal control cabinet use with a diameter
of 2.2 mm.
