Fiber optic cable, function - GF82.00-P-4000-04A

The fiber optical cable consists of plastic with a fiber diameter of 1 mm. Each fiber optical cable is protected against mechanical damage and against admission of outside light with the help of an orange-colored insulation. The light for the data transfer in the digital data bus (D2B) has a wavelength of 650 nm; by comparison, visible light lies in the range of blue with 400 nm to red with 800 nm. Optical attenuation of the light signal can occur in the fiber optic cable. Attenuation of the optical signal in the fiber optical cable is dependent on:

• the length of the line between the individual components
• the bending radii when routing the fiber optical cable, which must have min. bending radius = 25 mm
• the condition of the insulation of the fiber optical cable
• A passive connector; this is used when a component is removed from the digital data bus (D2B) due to a fault.

To ensure the functional availability of the remaining components, the digital data bus (D2B) is closed again using a passive connector. The fiber optical cable has two different connection ends:

• The fiber optical cable input, which is the output to each control unit. This is marked in "white".
• The fiber optical cable output, which is the input to each control unit. This is marked in "red".
