Patent number: 11489591Abstract: A system for monitoring a signal on an optical fiber includes a fiber optic connector having a housing couplable to a receptacle. An optical fiber that transmits a first optical signal has first fiber core at least partially surrounded by a cladding and has a first end terminating proximate the housing. The first optical signal is transmitted along the first fiber core. An optical tap has a first tap waveguide arranged and is configured to receive at least part of the first optical signal as a first tap signal. The first tap waveguide comprises an output port for the first tap signal for directing the tap signal to a detector unit. In other embodiments, a detector unit detects light from the optical signal that is propagating along the fiber cladding.Type: GrantFiled: November 17, 2020Date of Patent: November 1, 2022Assignee: COMMSCOPE CONNECTIVITY BELGIUM BVBAInventors: Koen Huybrechts, Jan Watté, Stefano Beri

Patent number: 10924182Abstract: The invention is directed to a system and method for troubleshooting in an optical data network that has a laser transmitter/receiver unit that outputs a data signal and an OTDR unit that produces an OTDR probe signal. The data and OTDR probe signals, typically at different wavelengths, are coupled into one end of a trunk fiber which is coupled at its far end to an optical circuit that includes a number of wavelength-selective optical switches and has multiple outputs that are directed to different end users. The optical switches are configurable so as to provide the OTDR probe signal to only one of the optical circuit's outputs while maintaining the data signal at the same output, while also maintaining the data signal, without the OTDR probe signal, at other outputs.Type: GrantFiled: October 21, 2016Date of Patent: February 16, 2021Assignee: CommScope Connectivity Belgium BVBAInventors: Jan Watté, Cristina Lerma Arce, Stefano Beri, Jan Jozef Julia Maria Erreygers, Koen Huybrechts

Publication number: 20180045893Abstract: Integrated optical devices include various configurations of active optical switches and other passive components such as splitters that are useful for controlling signals in optical data transmission networks. An optical switch may be used to switch light between waveguides on different substrates. The active optical switch may include one or more microfluidic droplets that are controllably movable relative to the coupling region to change the amount of light couplable between the first and second switch waveguides. Different configurations of the droplets can be controlled for operating the switch in different switching states. An optical switch can be included in an end use transceiver device for remotely controlling an optical time domain measurement. A microfluidic switch can be used to control wavelength-selective reflection in a waveguide reflector.Type: ApplicationFiled: December 18, 2015Publication date: February 15, 2018Applicant: CommScope Connectivity Belgium BVBAInventors: Koen HUYBRECHTS, Jan WATTE, Cristina LERMA ARCE

Patent number: 8599478Abstract: A method is provided for all-optical regeneration of intensity modulated optical signals. A DFB laser diode is selected such that it has a gain bandwidth comprising the signal wavelength, the signal wavelength being outside the stopband of the DFB laser diode. Furthermore, the DFB laser diode is selected such that it can have a bistable amplification characteristic for the signal wavelength showing a hysteresis with an ascending branch and a descending branch, the ascending branch located at a higher input power level than the descending branch. The DFB laser diode is driven such that it operates in the bistable amplification regime, the descending branch of the hysteresis curve located at an input power level above the lower power level of the optical signal pulses and the ascending branch of the hysteresis curve located at an input power level below the upper power level of the optical signal pulses.Type: GrantFiled: September 13, 2010Date of Patent: December 3, 2013Assignees: IMEC, Universiteit GentInventors: Geert Morthier, Koen Huybrechts
