The LR-01 consists of either one (PP-version) or two sets of fibre optic ports, each with
its separate transmitter and receiver, and one L

ORKS
®
FTT-10A transceiver for the
TP network. Figure 3.1 illustrates the communication ports on the LR-01.
If there are only two network segments that are to be connected, the point to point
version of LR-01 could be used. If the network contains of more than two segments,
the data needs to be retransmitted onto the fibre link to other connected network
segments.
The LR-01 with its two sets of fibre optic ports can then be used to build bus or ring
topology fibre links.
Figure 3.2 illustrates the general data flow when data is received from a TP segment.
Incoming data on a fibre link is transmitted onto the L

TP network as well as
forwarded to the next unit on the fibre link.
