Abstract: An optoelectronic transducer includes an enclosure provided with an optical transceiver port allowing a forward light beam and a backward light beam to pass therethrough and at least one electrical transceiver port; an optical module consisting of a plurality of optical elements that are pervious to light and can respectively reflect a specific one of many lights of different wavelengths; and an optoelectronic module consisting of at least one optical-electrical conversion element and at least one electro-optical conversion element, which are electrically connected to the electrical transceiver port. The optoelectronic module works with the optical module to converge multiple electrical signals to a single light beams. Two corresponding optoelectronic transducers can be connected via an optical fiber cable to form an optical fiber transceiver module for transmitting multiple electrical signals via the optical fiber cable.

Abstract: A ferrule of optical cable with multi cores includes a casing and at least one main body. The main body is connected to the casing. A plurality of main body through-holes are formed on the at least one main body. The casing and the main body are separately formed and fixed to each other. A plurality of optical fibers of a fiber optical cable pass through the main body through-holes and extrude out of the casing.

Abstract: An optical fiber module includes: a casing; a first optical fiber having a portion in the casing; a first optical transmitter in the casing, wherein the first optical transmitter is configured to emit a first optical signal to the first optical fiber; a second optical fiber having a portion in the casing, wherein optical signals transmitted through the second optical fiber are independent from those transmitted through the first optical fiber; and a first optical receiver in the casing, wherein the first optical receiver is configured to receive a second optical signal from the second optical fiber.
