<p>An optical module includes a MT-Ferrule (5) and a photoelectric conversion unit (4). Said MT-Ferrule (5) is used for connecting multiplex optical channels (54) located at the outside of the optical module with multiplex optical channels (41) of said photoelectric conversion unit (4), thus realizing the coupling and the transmission of multiplex single-mode optical signals between them. Said photoelectric conversion unit (4) is used for converting the multiplex single-mode optical signals outputted from the MT-Ferrule (5) into multiplex electric signals and outputting them, and used for, driven by inputted multiplex electric signals, generating multiplex single-mode optical signals and outputting them into said MT-Ferrule (5).</p>
