Patent CA-2189664-C (CA)
Inventor: FLAVIO FONTANA
IPC: H04B10/564
Filed: 1996-11-05
Granted: 2002-10-15
Abstract: The device and method are based on tapping off a predetermined line  signal  fraction  and  inputting  it, together  with  a  continuous  pumping  radiation,  to  a resonant cavity which comprises a non-linear wave guide.         The value of the pumping wavelength is related to the wavelength of the line signal pulses to produce therewith a four-wave mixing  (FWM)  effect in the non-linear wave guide. In travelling the non-linear wave guide, a clone signal is generated by FWM effect which duplicates the pulse sequence of the line signal at a clone wavelength.          By adjusting the length of the resonant cavity such that, in inputting the line signal,  each of its pulses will come in at exactly a pulse of the clone signal which is being circulated within the cavity, a clone signal can be circulated  within  the  resonant  cavity  whose  pulse sequence represents the optical clock signal sought.

Title: Fiber optic cable monitoring system
Inventor: VOKEY DAVID E
IPC: G01M3/04
Filed: 1992-04-10
Granted: 2000-02-29
Abstract: The invention provides a monitor for monitoring the condition of fibre optic communication cables. The system employs one or more of the optical fibres of a cable to monitor the cable structure for damage or kinks. By using two separate laser sources and simultaneously monitoring the optical losses at two distinct and separate wavelengths, the loss signature of the monitored fibre is determined, analyzed and related to the mechanical condition of the cable structure. To monitor splice points for moisture, a special optical splice sensor unit detects any penetration of water into the splice and transmits a coded alarm signal over the monitored fibre to the optical receiver. Every splice location is assigned a unique sensor code. The optical splice sensor is driven by moisture detection cell, which forms a single cell water activated battery. Water entering the monitored splice closure wets the tape, which activates the cell. The cell generates sufficient voltage and current to power timing, code generation and modulator circuits in the sensor unit for an extended period of time. The activated circuit drives a modulator which modulates the light travelling down the fibre. The modulated light is monitored at the equipment office and the address of the alarming sensor decoded.
