Publication number: 20220205866Abstract: Techniques for extending distributed acoustic sensing (DAS) range in undersea optical cables are provided. For example, DAS range can be extended by transmitting and amplifying a DAS signal along multiple spans of a first optical fiber, routing or bypassing the DAS signal from the first optical fiber to a second optical fiber different from the first fiber via a high-loss loopback architecture, and returning and amplifying the DAS signal along the same multiple spans back to a DAS device. The DAS device may then receive and process the DAS signal to detect any changes in the DAS environment. The loopback configuration may be based on different types of loopback architecture.Type: ApplicationFiled: December 28, 2020Publication date: June 30, 2022Applicant: SUBCOM, LLCInventors: Georg Heinrich Mohs, Alexei N.

Patent number: 10637565Abstract: A system and method consistent with the present disclosure provides for automated line monitoring system (LMS) baselining that enables capturing and updating of operational parameters specific to each repeater and associated undersea elements based on high loss loopback (HLLB) data. The captured operational parameters may then be utilized to satisfy queries targeting specific undersea elements in a Command-Response (CR) fashion. Therefore, command-response functionality may be achieved without the added cost, complexity and lifespan issues related to deploying undersea elements with on-board CR circuitry. As generally referred to herein, operational parameters include any parameter that may be derived directly or indirectly from HLLB data. Some example non-limiting examples of operational parameters include span gain loss, input power, output power, gain, and gain tilt.Type: GrantFiled: June 26, 2019Date of Patent: April 28, 2020Assignee: SubCom, LLCInventors: Lee Richardson, Georg Heinrich Mohs, Yunlu Xu, Richard Kram, Lara Denise Garrett, Jonathan M.

The nQAM signals may be generated by a lower-level modulator, such as a BPSK modulator, QPSK modulator or lower-level QAM modulator, with binary driving signals. Different parameters of the DLIs, such as free spectral range (FSR), phase shift, and amplitude imbalance, may be selected to accomplish the desired higher-level nmQAM depending upon the nQAM signal.Type: GrantFiled: February 23, 2011Date of Patent: August 12, 2014Assignee: Tyco Electronics Subsea Communications LLCInventors: Hongbin Zhang, Jin-Xing Cai, Yu Sun, Carl R.
