Abstract: An apparatus and method of ablating obstructing vascular or arterial material is provided including a pre-polished optical fiber for providing a specific laser light path focal point inserted within a catheter having a protective shield. The optical fiber may be controlled for axial and rotational movement via an optical rotary coupler and a rotary axial stepper to provide rotation speed of up to 5,000 rpm and incremental axial movement from between 1 micron to 1 millimeter. A laser light source is provided for adjustment of the wavelength of the laser light emitted from the end face of the optical fiber to correspond to the absorption characteristics of the material to be ablated.

Abstract: An optoelectronic transceiver having a small footprint and including a laser diode package contained within a subassembly mounted within a housing of the transceiver. The housing includes latches for retaining subassemblies therein. Subassemblies include first apertures for receiving mounting pins to lock the subassemblies within the housing. Plug latch members are mounted onto the subassemblies. Optical transmitter and receiver circuits and one row of nine contacts are mounted to a printed circuit board mounted within the housing of the transceiver.
