PURPOSE:To reduce cost and to make the title system immune to noise by forming a specific bus type LAN, detecting a transmission data with a recognition data and receiving it by an exclusive reception section. CONSTITUTION:A driver 2 for an optical local area network (optical LAN) is connected electrically to an electronic computer 1, where 2 couples of optical transmission equipments each composed of a reception section 4 and a transmission section 5 are connected respectively to an optical fiber 3 to form a bus type network. Then the transmission data with a recognition data is detected by the reception section 4 to receive the data. Thus, the inexpensive and simple local network is obtained and the noise immunity is improved. |
