摘要： An optoelectronic transmitter is provided including a semiconductor laser as the active optical transmitting element. The transmitter includes first and second printed circuit boards, with the first printed circuit board having mounted thereon electronic components and circuitry for driving the optoelectronic transmitter. A transmitting optical sub-assembly (TOSA) is mounted to the second printed circuit board. The second printed circuit board has an array of solder pads disposed on the back surface thereof, and the first printed circuit board has a corresponding array of solder pads disposed along an outer edge of the board. Spacing of the solder pads is such that when the first printed circuit board is placed in perpendicular abutment against the outer edge of the first printed circuit board, the solder pads formed on the first printed circuit board are aligned adjacent to the solder pads disposed on the back of the second printed circuit board. Solder joints are then formed in the angular space between the solder pads disposed on the first and second printed circuit boards, bonding the boards together while simultaneously providing electrical connections between the various components mounted on the individual printed circuit boards. An improved control circuit for driving the semiconductor laser transmitter facilitates this arrangement. The improved control circuit provides both automatic power control and laser slope compensation in order to normalize the output characteristics of individual transceivers. An alternate embodiment further includes a laser fault latching circuit for disabling the laser transmitter, and providing laser fault indication.

摘要： The present invention provides in improved Transmitting Optical Subassembly (TOSA) for coupling an optical output signal from an optical transmitter to an optical fiber sheathed within a fiber optic connector ferrule. The TOSA includes a housing formed of precision molded plastic or machined metal. A first end of the housing includes an optics cavity configured to receive an optical element for emitting an optical signal. A second end of the housing is configured as a long bore configured to receive an optical fiber connector ferrule. The housing further defines a lens cavity for retaining a focusing element between the optics cavity and the ferrule receiving bore. Finally, the housing also includes an attenuator receiving aperture between the optics cavity and the ferrule receiving bore. The plug receiving aperture is configured to removably receive an attenuation plug whereby the optical output of the optical element passes through the attenuator plug and is attenuated. The present invention further provides a method of normalizing the output signal of optical transmitters by measuring the output signals of the transmitters, comparing the measured signals to a normal reference signal, and attenuating the measured signal in order to more nearly match the reference signal.

The transceiver module has a main housing which consists of a potting box with potting material inserted therein. In addition, a circuit board is encased by the potting material. The circuit board has an optical subassembly mounted thereon. The optical subassembly extends outside of the potting box through a recess. Correspondingly, a recess cover is provided for forming a liquid tight seal between the recess cover, the potting box, and the optical subassembly. The module housing may be pluggable via release levers having detentes received in apertures of a receptacle and a pluggable connector of the module mated within the receptacle. The receptacle may include grounding means such as a ground clip mounted within the receptacle and a protective door to limit electromagnetic emissions.
