Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a MODEM by performing communication among spots more than two by bidirectionally transmitting an optical signal modulated in a 1st modulation form and an optical signal modulated in a 2nd modulation form through the same transmission line optical fiber. SOLUTION: A signal C is converted to an analog modulated optical signal of an optical wavelength λ1 at optical transmission equipment 1a and inputted later to a photocoupler 1c connected to the equipment 1a. This signal is inputted through a transmission line optical fiber 100 to a photocoupler 2c at a spot 2 and demodulated to the analog modulated signal C at optical reception equipment 2a. On the other hand, a signal D is made a digitally modulated signal of the optical wavelength λ1 by optical transmission equipment 2a at the spot 2 and inputted to the photocoupler 2c. This signal is inputted through the fiber 100 to the photocoupler 1c at a spot 1. At one port on the output side of the coupler 1c, the optical signal connected to the optical reception equipment 1b and having intensity-distribution is transmitted to the equipment 1b and demodulated to the digitally modulated signal D.
