1. Overview
1.1 Introduction
The HFB DeviceNet Fiber Optic Modem is a multi-master and high performance Field bus
Control System (FCS). Our Fiber Optic Modem uses the fiber cable as its transmission
medium and utilizes Optical Fiber modulation/demodulation technology to changes the
electric medium into a light medium transmission.
The Fiber Optic Modem product eliminates many 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 system,
and potential lightning damage.
The HFB Fiber Optic Modem can be widely used, such as Industrial Controls, Intelligent
Transportation Systems (ITS), Industrial Networking, Supervisory Control and Data
(SCADA) and so on.
