摘要
A connection circuit arranged to connect at least one piece of electrical equipment (12) to an optical fiber (13) that might convey light signals of different wavelengths, the connection circuit comprising a wavelength multiplexer (16) having an upstream port (17) for connection 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 optical communication standard and each having both an optical port (26) connected to one of the downstream ports of the wavelength multiplexer and also an electrical port (27), an electrical processor component (35) having a communication port (36) via which the electrical processor component is arranged to emit and/or receive light signals (TXD, RXD), and a switch (45) arranged to connect the communication port of the electrical processor component selectively to an electrical port of one of the optical-electrical interfaces.
