CIRCUIT FOR CONNECTING A LOCAL AREA NETWORK TO AN OPTICAL FIBER ON WHICH LIGHT SIGNALS CONFORM TO DIFFERENT OPTICAL COMMUNICATION STANDARDS

摘要

Connection circuit arranged to connect at least one electrical equipment (12) to an optical fiber (13) on which light signals of different wavelengths are likely to pass, the connection circuit comprising a wavelength multiplexer ( 16) comprising an upstream port (17) intended to be connected to the optical fiber and a plurality of downstream ports (18, 19), a plurality of optical-electrical interfaces (24, 25) each compatible with at least one standard of optical communication and each having an optical port (26) connected to one of the downstream ports of the wavelength multiplexer and an electrical port (27), an electrical processing component (35) comprising a communication port (36) via which the electrical processing component is arranged to transmit and / or receive electrical signals (TXD, RXD), and a switch (45) arranged to selectively connect the communication port of the electrical processing component to an electrical port of one of the optical-electrical interfaces.
