摘要： In the method and apparatus for providing an optical fiber interconnect, a transmitter transmits an optical signal through an optical fiber. The transmitter does not transmit to a controller, information about the power of the transmitted optical signal near the input end of the fiber. The controller receives an indication of the power of a returned portion of the transmitted optical signal. The controller causes the lowering of the power of the transmitted optical signal to a predetermined level based the received indication.

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 mode scrambler comprises an optical fiber adapter having a diffuser disposed between optical fiber mating ends of the optical fiber adapter. When a single mode optical signal is launched in the mode scrambler, the mode scrambler converts the single mode optical signal to a multimode optical signal that has a substantially even intensity distribution across the modes.

摘要： In accordance with the invention a multiwavelength optical fiber transmission system is provided with a passive all-fiber optical router for add/drop multiplexing. The passive router is comprised of three fiber components: 1) a fiber directional coupler, 2) a fiber reflective grating filter and 3) a fiber notch filter. The specification describes optical routers from these components ranging in complexity from a three wavelength router to an N-wavelength router.

摘要： An active optical device comprises a glass, waveguiding structure disposed on a substantially planar principal surface of a substrate. The structure includes a silica-based, erbium-doped active core. The active core has an absolute erbium concentration of at least about 0.5.times.10.sup.20 atoms per cubic centimeter, and a radiative lifetime of the erbium lasing level of at least about 5 milliseconds. The active core does not contain significant amounts of alkali metals or alkaline earth metals but does contain at least two modifier metals. Also disclosed is a method for forming an active optical device, including the step of depositing an erbium-doped active core by sputtering.

摘要： Indiscriminately exciting the modes of a multi-mode optical fiber amplifier is avoided by an optical fiber amplifier design in which the excitation of pump modes in the core of a multi-mode fiber is controlled by controlling the pump light launching. The pump light is directed substantially along the center axis of a multi-mode fiber within a predetermined launch angle. Rather than exciting all modes, only lower order modes are affected.
