PHOTOELECTRIC COMPLEX LINK-TYPE TERMINAL AND PHOTOELECTRIC COMPLEX LINK-TYPE TERMINAL SYSTEM

摘要

PROBLEM TO BE SOLVED: To execute signal transmission and power supply between a terminal and a peripheral equipment by means of one photoelectric complex cable to reduce a handling time in wiring by providing a photoelectric complex port where an optical signal input/output port and a power source port are integrated. ;SOLUTION: The signal 1 outputted from the terminal 6 to a printer equipment is inputted to an E/O converting part and a laser diode(LD) 4 inside the terminal photoelectric complex port 5 and converted into an LD optical signal. An AC power source 2 is supplied to the printer equipment through a power terminal 3. A horizontal synchronizing signal 8 outputted from the terminal 7 and a monitor equipment, a vertical synchronizing signal 9, an R signal 10, a G signal 11 and a B signal 12 are FM-modulated by respectively different center frequencies in a signal multiplexing part 20. Then, an electric multiplexing signal obtained in the signal multiplexing part 19 is inputted to the E/O converting part and the laser diode(LD) in the terminal photoelectric complex port 41 and converted into the LD optical signal. The AC power source 13 is supplied to the monitor equipment through the power terminal 17.;COPYRIGHT: (C)1998,JPO
