2 INTRODUCTION
The LR-11 router offers an easy way to extend the distance between LONWORKS
®
78 kbit/s TP/FT network segments using a high-speed 1 250 kbit/s backbone fibre optic
network link.
LR-11 is based on Echelon’s RTR-10 standard router core module, this allowing
standard configuration and installation with tools such as LonBuilder
®
and LonMaker™.
LR-11 routers can be installed as repeaters, configured routers, or learning routers.
The LR-11 is equipped with either one (PP-version) or two pairs of fibre optic receivers
and transmitters. This allows the user to build either point to point-, bus- or ring
topology fibre links.

In a fibre ring, one of the LR-11 units will be assigned as a ring master and then having
the responsibility to stop messages from looping around the ring. The LR-11 has a builtin redundancy scheme that provides for fault tolerances in the fibre rings. There is a
maximum transmission distance on the fibre link depending on the available power
budget of the LR-11 units and losses due to attenuation in cables, connectors and splice
joints. With single mode fibre, distances up to 25 km can be reached.
For the fibre channel communication parameters, the LR-11 is by default set with parameters used for small network. Depending on the fibre length and the number of devices
the communication parameters may be changed to optimize performance. Section 4 will
discuss this matter in further detail.
