2 INTRODUCTION
The LR-01 offers an easy way to extend the distance between LONWORKS®78 kbit/s TP/FT network segments using a fibre optic link. The complete transparent conversion to and from the fibre optic media facilitates the installation procedure by eliminating the need for any additional network addressing or software configuration.
An LR-01 link acts as a TP/FT-10 physical layer repeater with the following additional features:
• The channel can be extended to a much longer distances using fibre optic cables
• Up to ten network segments
• Offers immunity against electrical interference

Figure 2.1 Up to ten network segments
The EIA-709.3 specification states a maximum delay of 36 µs and a maximum of one repeater between any two nodes. Using the LR-01 this delay restriction will normally be met if the total fibre cable length between the two units is restricted to 5.6 km thus two LR-01 units form one physical layer repeater. The recommended maximum number of LR-01’s connected together is ten, however as more units are connected together the total length of fibre has to be reduced to keep within the delay budget (please see 3.4 channel delay).

The LR-01 is equipped with either one (PP-version) or two pairs of fibre optic receiver and transmitter. This allows the user to build either point to point-, bus- or ring topolo­gy fibre links.
