Patent number: 11349566Abstract: Devices, computer-readable media and methods are disclosed for determining reachability for a wavelength connection in a telecommunication network. For example, a processor deployed in a telecommunication network may calculate a fiber loss on a link in the telecommunication network using optical power measurements and determine that a destination node of a wavelength connection is not reachable via a path that includes the link based upon the fiber loss of the link that is calculated. In one example, the determining is based upon a number of links in the path, an effective fiber loss for each link in the path, a penalty for nodes in the path, and an acceptable loss value. The processor may further perform a remedial action in response to determining that the destination node of the wavelength connection is not reachable via the path.Type: GrantFiled: November 30, 2020Date of Patent: May 31, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: Sheryl Woodward, Kathleen Tse, Martin Birk, Angela Chiu, Balagangadhar Bathula

Patent number: 11329751Abstract: Devices, computer-readable media and methods are disclosed for verifying that an optical transmit/receive device is correctly installed. For example, a processing system including at least one processor may activate a first light source of an optical transmit/receive device of a telecommunication network and detect a receiving of a light from the first light source at a port of an optical add/drop multiplexer of the telecommunication network. The processing system may then verify the optical transmit/receive device and the port of the optical add/drop multiplexer match a network provisioning order, when the receiving of the light from the first light source is detected, and may generate an indication that the optical transmit/receive device is correctly installed, when the optical transmit/receive device and the port of the optical add/drop multiplexer match the network provisioning order.Type: GrantFiled: May 17, 2021Date of Patent: May 10, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: Simon Tse, Martin Birk, Shweta Vachhani, Kathleen Tse
