摘要： Methods of packaging a high density optical module. In one example embodiment, a method of packaging the high density optical module includes various acts. First, a first detachable fiber assembly is connected to an optical component disposed in the module such that the connection between the fiber assembly and the optical component is disposed inside a housing of the optical module. Next, the fiber included in the fiber assembly is spooled around a spooling assembly. Then, the receptacle is secured in a receptacle holder such that the receptacle is able to connect with an external fiber connector. Next, the fiber assembly is detached from the optical component. Finally, the optical component is heated such that a ball grid array connection, that connects the optical component to a high speed printed circuit board, flows such that the optical component can be removed from the high speed printed circuit board.

摘要： An optical module and packaging thereof. A high speed optical module, such as a transceiver or transponder is disclosed. A fiber assembly including a receptacle, a fiber, and a modified connector are provided and enable an optical connection from inside of the optical component to outside of the component. Internally, the fiber assembly is detachable from an internal optical component. the optical component is connected to a PCB using a ball grid array. By detaching the fiber assembly, the optical component can be changed-out without damaging the fiber. The fiber is spooled inside the module to protect the fiber around a spooling assembly that is integrated with the receptacle holders that form part of the module's ports.

摘要： A low cost automatic frequency control system measures short duration radio frequencies with high a degree of accuracy within 0.5 MHz. The system is programmable to allow applicability over a wide range of frequencies within the required accuracy and various signal durations. The system includes circuits to digitize the source signal to a digital pulse train and asynchronously sample the pulse train to obtain a count of the positive edges of the pulses over a sufficient number of samples. A microprocessor computes the statistical average of the count and accurately determines the frequency of the source signal. The system further includes a feedback path to implement correction to the source signal based on the measured frequency.

摘要： An air bearing slider used with a thin film magnetic head is formed with a corner recess and a taper at the leading edge. The taper is disposed between the corner recess and one side of the slider. A central polygon-shaped recess is bounded by pads which are joined by a connecting section. In an alternative embodiment, a recess at the leading edge separates the taper into sections. In another embodiment, a second corner recess is provided at the leading edge and the taper is disposed between the first and second corner recesses. The shaped recesses and tapers improve the flying characteristics of the slider and enhance air bearing stiffness. A single etch process is used to form the recesses and side reliefs of the slider.
