Latest Patents

Cahill's latest patents include an innovative optical time domain reflectometry (OTDR) device and methods. This device features an optical transmitter, an optical receiver with multiple operating settings, an optical coupler, and a processor. The optical transmitter generates a probe signal comprising a train of pulses. The optical receiver generates time-varying measurements of a back-reflected signal resulting from the injection of respective pulses of the probe signal into an optical fiber link. The optical coupler injects the probe signal from the optical transmitter into the optical fiber link and directs the back-reflected signal from the optical fiber link to the optical receiver. The processor generates a probe trace of the optical fiber link from the first time-varying measurements of the back-reflected signal, identifies an intra-scan first transition point from the probe trace, and generates a range-extended trace of the optical fiber link from the second time-varying measurements of the back-reflected signal in which the optical receiver transitions from a first operating setting to a second operating setting at the intra-scan first transition point.

Another notable patent is for fiber span characterization utilizing paired optical time domain reflectometers. This system provides advanced characterization of an optical fiber span based on the use of a pair of optical time domain reflectometers (OTDRs), located at opposing end terminations of the span being characterized. Each OTDR performs standard reflectometry measurements and transmits the resulting OTDR trace to monitoring equipment. The pair of OTDR traces is combined in a particular manner to create an OTDR trace of the entire fiber span, effectively doubling the operational range of prior art OTDR measurement capabilities.
