Abstract: A surge protector for highspeed data networks is provided wherein a circuit board having a ground plane formed on one side of the circuit board, has respective pairs of conductive traces forming impedancematched transmission lines on the other side of the circuit board. Surge protection devices are connected in series with the conductors and with the ground plane. A compensating reactance may be provided along the transmission lines to correct for parasitic capacitance introduced by the threshold voltage conductor devices. Shielded and isolated connectors may be provided at either end of the circuit board to minimize insertion loss and provide isolation between respective transmission lines.

Abstract: A device and method of use for splicing the free ends of a pair of optical fibers together. The device comprising a two-section housing and a capillary tube. One section of the housing includes a pair of groove supports and a recess for receipt of the capillary tube. The other section includes a pair of cantilevered arms. Each support groove is disposed adjacent a respective end of the capillary tube and aligned with a longitudinally extending portion of the passageway extending through the capillary tube. The cantilever arms are disposed over the respective support grooves to form respective spaces through with the free ends of the optical fibers may be passed to guide the fibers into the capillary tube passageway where they abut each other. The cantilever arms hold the fibers securely in the support grooves.

Abstract: An optical fiber termination device is described which includes first and second housings supported for relative movement therebetween. The first housing supports an optical fiber cable and is insertable into a second housing which supports a cutting device for severing the cable and providing a termination end face. The composite structure is then insertable into a termination housing to provide optical connection with a further optical device.

Abstract: An insert or sleeve is fabricated from a glass-like material as a mica-filled glass and is of a longitudinal tubular configuration having a flat front surface with an aperture for accommodating a glass optical fiber. The aperture is coextensive with a fiber accommodating channel in said insert. The insert is surrounded and anchored into an outer plastic ferrule and a fiber when accommodated in said channel is broken at said surface which surface and fiber face are then polished to assure an optically smooth and polished fiber face which is free from debris damage during polishing.
