Abstract
An optical LAN terminal device includes an optical input connected to an external optical fiber so that an optical signal is supplied via the optical fiber to the input, an optical output connected to the optical fiber so that an optical signal is delivered via the optical fiber, a signal processor receiving an optical signal and carrying out electrical signal processing for the received optical signal, thereby being capable of generating and delivering a second optical signal, a bypass normally connecting the input and output to each other optically, a receiving branch branched off from the input or the bypass to transmit the optical signal from the input toward the signal processor, and a transmission branch branched off from the output or the bypass to transmit the optical signal from the signal processor toward the output.
