The optical waveguide modules LW215 and LW216 together form an optical transmission system for the data transmission of incremental sensor or transmitter signals via an optical waveguide. It is also possible to connect differential signals of any other sources with RS422 or push-pull HTL levels (for example incremental length measuring systems, glass scales, etc.).
Transmitter and receiver modules each have four completely independent channels with differential inputs and outputs. Signals with a maximum data rate of 2 Mbit/sec. can be transmitted on all four channels.
The component with the designation LW215 serves as a transmitting module for light transmission of up to 2000 meters. It converts the incremental signals from conventional sensors, measuring systems or rotary pulse encoders into optical fibre signals. The LW receiver (see LW216) then converts the optical signals back into the original incremental format.
