A transceiver module is provided. The transceiver module includes a housing, a latch and a torsion spring. The housing includes a positioning post and a block. The latch includes a wedging protrusion. The torsion spring includes a coil portion, a first extending portion and a second extending portion, wherein the first extending portion and the second extending portion are connected to the coil portion, the first extending portion includes a first free end, the second extending portion includes a second free end, and the first extending portion intersects the second extending portion at an intersection point on a projection plane. A first area, a second area, a third area and a fourth area are defined by the torsion spring clockwise around the intersection point, the coil portion surrounds the positioning post in the first area, and the first free end is adapted to connect the latch.

An optical communication device includes a top cover, a bottom cover, a circuit board and an electrostatic discharge element. The bottom cover is disposed opposite to the top cover, and an accommodating space is formed between the top and bottom covers. The circuit board is disposed in the accommodating space. The electrostatic discharge element is disposed on the circuit board and electrically connected to the circuit board.

Optical communication device

A connecting module comprises a body, a housing and a transmission device disposed in the body. The transmission device comprises a fixed element having a guiding slot, a slider and a movable bar. The movable bar drives the slider to horizontally move along the guiding slot, to disengage the body from the housing.

Connecting module for communication

A protection circuit is coupled between a secondary winding of a transformer and a load. When voltage at the secondary winding of the transformer becomes abnormal, the protection circuit disconnects the power connection to the load so as to protect the load from damage. When the voltage at the secondary winding of the transformer returns normal, the protection circuit restores power to the load.

Protection circuit

The invention provide an optical fiber transmitter by both suppressing stimulated Brillouin scattering (SBS) effect and composite second-order (CSO) distortions at an optimized condition. The optical fiber transmitter includes a frequency modulator generating a first tone microwave with frequency f coupled to a laser source, and a phase modulator generating a second tone microwave with frequency f coupled to an external phase modulator, so as to broaden the modulated light spectrum. The first tone microwave with frequency f is set to be greater than 2 to 3 times of the highest frequency content in the modulating signals. The second tone microwave with frequency f is designed to be close to a harmonic frequency of f and no less than three times of f . The first tone microwave with frequency f and a second frequency f are inputted to two power amplifiers, respectively, and then are respectively inputted to a laser source and an external phase modulator. These two power amplifiers are controlled by an microprocessor to automatically adjust a desired phase modulation index at 1.4 for the optical fiber transmitter with a repeaterless design or at an desired index depending on the desired transmission distance in a repeater design. The external phase modulator is coupled to a pare of fiber amplifiers for the repeaterless design or several pairs of fiber amplifers coupled in series for the repeater design. The last pair of the fiber amplifiers are coupled to optical receivers.
