fiber to serial converter/ fiber to RS485/RS422

Product Overview:
► Fiber optic MODEM is a converter of RS-485/422 serial to fiber optic (also
called Optical Modem or fiber MODEM), which was professionally designed to solve
communication between RS485/422 Serial signal and Fiber optical signal .
► Fiber optic modem can provide transparent transmission from serial port to
optical fiber serial for users. The users do not need to change the existing
software . Fiber optic MODEM can stably and long distance transfer serial signal
to remote. The working mode of the Fiber optic modem is in pairs , which can more
easily revert users’ serial signal to serial signal through the fiber
transmission.
► Optical signals was transfer in optical fiber . there is no electrical
conductivity . it will not affected by electromagnetic wave and thunder . which
has a strong anti-interference ability. Especially suitable for the working
environment is harsh, distant outdoor.
