Mounting
4.5
Mounting distance for parallel operation of data transmission systems
If it is necessary to operate multiple optical data transmission systems next to one another, the minimum
mounting distances must be maintained.
The minimum mounting distance between two optical data transmission systems is determined by the fol-
lowing criteria:
• Maximum data transmission distance
• Frequency-offset mounting (F3/F4 / F4/F3)
• Identical frequency mounting (F3/F4 / F3/F4)
• Transmission beam spread of the devices
The standard beam spread is ±0.5°.
