    摘要： An optical fiber connector plug includes a housing through which extends a cable containing at least one optical fiber. A ferrule, which is supported by the housing, is provided for receiving the optical fiber. The ferrule has a mating facet and an opposing rear facet located in the housing. The ferrule has at least one guide pin thru-hole and at least one optical fiber thru-hole extending between the mating facet and the opposing rear facet. The guide pin thru-hole has an opening portion extending inward from the mating facet. The opening portion is tapered outward to meet the mating facet in an oblique manner such that the opening portion has a diameter in the plane of the mating facet that is greater than a diameter of a remainder of the guide pin thru-hole.

    摘要： A tunable semiconductor laser comprises a gain section having an MQW active region, a uniform pitch grating DFB region, and first waveguide. A composite reflector, including a second MQW region and a second waveguide, forms a cavity resonator with the DFB region. A tuning voltage applied to the composite reflector induces refractive index changes, thereby allowing the center wavelength to be altered. A dither signal applied the composite reflector broadens the spectrum of the laser output, thereby reducing SBS in fiber optic systems

    摘要： The specification relates to a repeaterless branch powered fiber optic communications system. The system comprises an optical fiber cable trunk, configured in ring topology, with one or more telecommunications hub, and one or more branching unit serially interconnected therein. Branching units are provided as convenient add/drop points along the trunk ring from which branch fiber optic cable radially extend to cable stations. Cable stations insert and extract telecommunications traffic from the trunk ring over the branch fiber optic cables. In addition, the branch fiber optic cables are also coupled to light emitting power sources. The branch fiber optic cables deliver the energy produced from these power sources to optical amplifiers serially embedded within the branch fiber optic cables, the branching units, or the optical fiber cable trunks. The optical amplifiers convert the energy delivered from the branch fiber optic cables into amplified telecommunications signals. Thus, remote pumping or energy delivery is achieved without the requirement of additional optical fiber cable runs and further, using solely passive repeaterless components.
