An optical transducer includes a multi-port light emitting unit for distributing sensing light to minor bundles of optical fibers connected to input ports thereof and a multi-port light detecting unit for converting the sensing light to photo-current; an optical fiber plug, a socket and light detecting elements received in the socket are assembled in the multi-port light detecting unit; the optical fiber plug is made of semi-transparent colored synthetic resin, which is transparent to short-wavelength light and non-transparent to long-wavelength light, so that the minor bundles are adhered to the optical fiber plug through adhesive compound cured in the radiation of the short-wavelength light; the long-wavelength light serves as the sensing light so that leakage light does not reach the adjacent input ports.
