Note: Bi-di fibre can be used.

The bi-di transceivers must always be used in pair, see example:

Point-to-point communication via fibre optic network

With only two network segments, the most cost effective solution is to use two point-
to-point LRW-102PP units to create a single fibre optic connection.

The point-to-point connection provides a totally transparent fibre link which means that
all data received on one units TP/FT port will be forwarded unchanged to the other port,
as illustrated in the figure.
