Abstract: A connector for optical fibers comprising a plug assembly and a first ferrule mounted coaxially therein, a receptacle assembly and a second ferrule mounted coaxially therein, wherein at least one of the plug-mounted ferrule and the receptacle-mounted ferrule is biased outwardly from a fiber-entry end of the ferrule. An alignment sleeve optically connects the ferrules and maintains the optical connection during translation of one of the plug assembly and the receptacle assembly in a longitudinal direction relative to the other.

Abstract: A method and multicoupler for a receiver at a base station in a cellular/PCS radio communication system includes a cooled container that is mounted on an antenna tower at the base station. The container is mounted on the antenna tower adjacent an antenna and contains thereinside a preselector filter, a highly linear amplifier, and a directional coupler that are cooled to a temperature less than 175.degree. K. and greater than 100.degree. K. A power splitter is connected between the output from the container and the radio system receiver, and is located at a ground station near the base of the antenna tower. Cooling the components inside the container, particularly the amplifier, to a temperature of about 150.degree. K. reduces the noise from the multicoupler so that base station range is extended, building penetration is improved, and subscriber transmit power may be reduced.
