Robust - Operate in
severe environment
Ideal alternative to cable & radio transmission data transfer systems. The ODL LDT's are robust Lase Data transmission devices specifically developed for heavy industrial use over long ranges.
Laser transmission has none of electromagnetic difficulties associated with radio transmission and provides greater flexibility in use. Secure and reliable transmission in duplex form is assured with in-built continuous self check of the system function.
Operating Technique
These Laser Transmission devices operate via FSK modulation, the transmitter converting the electronic data into laser signals via the laser diode and the Receiver converting the modulated laser signal back to electronic data.
To ensure complete signal integrity the data is transmitted in coded dual frequency. As a result of this dual transmission frequency, external influences, such as reflections and other optical influences do not influence the laser transmission.
