Abstract: A coaxial cable end connector includes two hollow and coaxial inner and outer sleeves. The outer sleeve is provided with at least one transverse slot for receiving a clamping structure therein. The clamping structure is formed at a bottom surface with a plurality of teeth. When a coaxial cable is inserted into the end connector, the jacket and the braided conducting sheath of the cable are located in an annular space between the inner and the outer sleeve. By forcing the clamping structure toward a center of the outer sleeve, the teeth at the bottom surface of the clamping structure are brought to tightly press against and connect to the jacket of the coaxial cable.

Abstract: A connector ensuring good mechanical and electrical connection to a coaxial cable includes a metal housing; an insulating element mounted in the metal housing and having a split end portion; a connecting terminal inserted in the split end portion of the insulating element to thereby associate therewith, and having a split end portion for receiving and electrically connecting to a center conductor of a coaxial cable; and a fixing element attached to an outer side of the metal housing, and having a first pair of wings inward bent to compress against the split end portion of the insulating element for the same to apply a force against the split end portion of the connecting terminal, so that the center conductor of the coaxial cable is firmly held to the connecting terminal without the risk of loosening therefrom.

Abstract: A coaxial cable connector comprises a head and a hollow cylinder. The hollow cylinder comprises a protective cylinder, a tubular shaft, and an elastic cylinder. The tubular shaft comprises a guide hole, a plurality of ladders, a locking flange, and a plurality of hooks. The elastic cylinder comprises a trench and a hook at one end and a locking ring defined by a notch near the other end. A bended metal tube having a stopper is mounted on the protective cylinder. In the coupling process, the coaxial cable inserts into the hollow cylinder. By using a pressure from a tool to break the notch of the elastic cylinder, the locking ring is separable from the elastic ring, and the locking ring shifts forward continuously along an inclined surface of the notch. Since the protective cylinder restrains the locking ring, the connector can couple with the coaxial cable tightly by pressing down the locking ring.

Abstract: The invention relates to an electro-optical arrangement for coupling light signals into an optical waveguide, which has a laser diode for emitting light signals and a microlens, which focuses light signals emitted by the laser for coupling into the optical waveguide. According to the invention, the microlens is arranged on a carrier carrying the laser diode.

Abstract: An optical device for processing an optical signal includes a crystal wedge, a polarization modulator, and a reflective element. The crystal wedge spatially separates an input optical signal into a first beam component having a first polarization state and a second beam component having a second polarization state. The crystal wedge has an optical axis arranged at an optical axis angle such that the first beam component and the second beam component converge. The polarization modulator changes the polarization state of the first beam component and the polarization state of the second beam component in response to a control signal. The reflective element reflects the first beam component and the second beam component such that the crystal wedge spatially recombines a portion of the first beam component having the second polarization state with a portion of the second beam component having the first polarization state to form an output optical signal.

Abstract: Devices and methods for equalizing the gain of an optical amplifier are described. For devices including harmonic filters that are controllable by amplitude control voltages and phase control voltages, techniques for controlling the amplitude control voltages and phase control voltages are presented. Additionally, device architectures are described by which an incoming optical signal is equalized to compensate for uneven gain in prior amplifiers or other optical components, and in which the incoming optical signal is received at a beam displacer and separated into orthogonal component beams, wherein the beams are counter-propagated through the equalizer in opposite directions through the same spatial path so as to minimize or eliminate the effects spatially dependent imperfections in the equalizer.
