The star distributor is made by coupling two or more
OZD 485 G12 BAS via the electrical interfaces. Lines or
other star distributors can be connected to the optical
interfaces of the coupled repeaters.
The termination at the start and end of the star point lead must have the same resistance values as the termination
of the bus.
The star distributor can be used to create bridges
between single-mode and multi-mode fiber links.
