Patent CA-2110800-A1 (CA)
Inventor: BARKER PHILIP A
IPC: C03C25/10
Filed: 1992-07-01
Abstract: An optical fibre package suitable for installation using a fibre blowing process comprises at least one optical fibre, an inner coating about said fibre, and an outer resin coating about said inner coating, said resin coating including a significant plurality of particulate inclusions at least 10  mu m across, wherein the concentration of the particulate inclusions is significantly greater at the outer surface of the resin coating than at the inner limit of the resin coating. The inclusions may be hollow glass microspheres or mica flakes. The relative absence of significant particulate inclusions at the inner limit of the resin coating improves the mechanical performance of the fibre package relative to similar known packages. The presence of significant inclusions at the outer surface of the resin coating tends, during a blowing process, to increase viscous drag effects and to reduce friction between the package and the duct into which the package is blown, thereby enhancing blowability. <IMAGE>

Patent CA-2121367-A1 (CA)
Inventor: UDD ERIC
IPC: H04B10/43
Filed: 1993-08-19
Abstract: A high speed secure fiber optic communication system that includes a coherent alarm system utilizes a pair of single mode fiber optic cables in combination with one or more light sources, phase modulators, detectors and polarization scrambling elements to form a Sagnac interferometer. The phase modulator is driven so that counter propagating light beams in the Sagnac loop experience a different optical path as they pass through the loop. When the two beams are recombined on the central beamsplitter of the Sagnac loop, the two beams interfere with each other and the data impressed as phase modulation on the light beams by the phase modulator is recovered as amplitude modulation on the output detector of the Sagnac interferometer. The coherent alarm system applies a relatively low frequency background signal to the Sagnac interferometer and watches for changes occurring to the background signal that indicate the presence of an intruder. Although the system is very secure, such coherent alarm systems with or without other alarms, intrusion control, random pathlength changes and the like can make undetected, unauthorized access to the system impossible with available interception techniques.
