An optical transceiver device includes a transmitter, a first and a second optical circulators and a receiver. The transmitter transmits a light signal uploaded with an electrical signal. The first and second optical circulators each include three ports. The second port of the second optical circulator is configured for transmitting the light signal circulated via the first and second ports of the first optical circulator and the first port of the second optical circulator, and the third port of the second optical circulator is configured for receiving an incoming light signal. The receiver receives the incoming light signal circulated back via the first port of the second optical circulator, and the second and third ports of the first optical circulator and converts the incoming light signal to be an electrical signal.

Optical transceiver device

An optical transmitter device includes a laser source, a driving circuit, and an optical modulator. The driving circuit is connected to the laser source. The driving circuit includes a thermistor configured for compensating the temperature variation of the laser source to stabilize the frequency of a laser beam output from the laser source. The optical modulator is configured for modulating the laser beam to form a plurality of second laser beams which have different frequencies.

A positioning fixture includes a clamping member, a supporting member, and a magnet. The clamping member includes a base body and an end portion protruding from the base body. The supporting member includes a main body and at least one protruding portion protruding from the main body towards the clamping member. The main body includes a mounting surface adjacent to the protruding portion. The main body defines a receiving groove at the mounting surface. The protruding portion engages with the end portion. The magnet is mounted on at least one of the supporting member and the clamping member, and at least another one of the supporting member and the clamping member is made of magnetic material. The optical component receives in the receiving groove, and the magnet provides a clamping force to clamp the optical component by using the supporting member and the clamping member.

Positioning fixture

An optical fiber connector includes optical fibers, a connector body, and a cover. The connector body includes optical lenses arranged at the first side surface. The connector body defines receiving grooves. Each of the receiving grooves has a V-shaped section and two slanted surfaces. The optical fibers are received in the grooves and as a result are correctly aligned with the respective optical lenses. The cover and the slanted surfaces of the receiving grooves cooperatively securely retain the optical fibers in the connector.

An optical transmitter module includes a light source, a first optical circulation unit, a first optical reflector, and an output unit. The light source emits a first light signal with a first wavelength, and a second light signal with a second wavelength. The first optical circulation unit includes three optical couplers and three optical isolators, which are alternately connected to one another to form a loop. The first optical circulation unit includes a first port at a first optical coupler, a second port at a second optical coupler, and a third port at a third optical coupler. The first port is optically coupled to the light source. The first optical reflector is optically coupled to the second port. The first optical reflector reflects the first light signal back to the second port. The output unit is optically coupled to the third port to output the first light signal.

Optical transmitter module

An optical communication device includes a transmitter module and a receiver module. The transmitter module includes a two laser sources, two optical modulators optically coupled to the two light sources, respectively, and an optical coupler, a semiconductor optical amplifier, an optical coupler, four optical band-pass filters or a demultiplexer, and an optical multiplexer optically coupled in series. The laser beams emitted from the two laser sources are converted into four laser beams having different frequencies due to a four-wave mixing effect occurring in the semiconductor optical amplifier. The receiver module includes a demultiplexer and four photoelectric conversion elements to receive the four laser beams respectively and convert them to electrical signals.
