1. Overview
1.1 Introduction
The LONWORKS Fiber Optic Modem is a multi-master and high performance Field bus Control
S stem (FCS). Our Fiber Optic Modem uses the fiber cable as its transmission medium and
utilizes Optical Fiber modulation/demodulation technolog to changes the electric medium into
a light medium transmission.
The LONWORKS Fiber Optic Modem product eliminates man of the disadvantages of copper
cable. Examples of these disadvantages are EMI/RFI, ground loops (electrical isolation with
fiber), high attenuation (high signal loss), short transmission distance between nodes of a
s stem, and potential lightning damage.
The LONWORKS Fiber Optic Modem can be widel used, such as Industrial Controls, Intelligent
Transportation S stems (ITS), Industrial Networking, Supervisor Control and Data (SCADA)
and so on
