  • Publication number: 20240007191
    Abstract: A method for tuning one or more tunable optical transceivers is disclosed herein. A controller assigns a particular wavelength to a tunable optical transceiver of the one or more tunable optical transceivers, where the one or more tunable optical transceivers and the controller are connected via an Inter-Integrated Circuit (I2C) interface. The tunable optical transceiver transmits an optical signal using the particular wavelength, where the particular wavelength is finalized for the tunable optical transceiver when an interrupt at a receiving port of the tunable optical transceiver is received.

  • Patent number: 11750282
    Abstract: The present disclosure provides a method and system for configuring an optical time domain reflectometer (OTDR) in a gigabit passive optical networks (PON), characterized by the steps of: collecting network data of the network to be scanned by switch controller to characterize said network; collecting data from various optical network terminals (ONTs) of the gigabit passive optical networks (GPON) by an OTDR and the Switch Controller to form a training database, the training data is used to train the method; optimizing the parameters of the optical time domain reflectometer (OTDR) based on the network data and the training database by a processor provided on the switching controller using machine learning. For point-to-multipoint (PMP) networks such as PON, the present method and system provides optimal set of parameters to configure OTDR before performing trace.

  • Patent number: 11567893
    Abstract: The present disclosure relates to a mirrored serial interface (MSI) for accessing peripherals through four wire serial interface. More particularly, the present disclosure is related to serial peripheral protocol with looped back mechanism in which contents of source data line are looped back onto the destination line and compared at every clock edge to ensure data sanity and to assert presence of slave and master device during and between cycles.

  • Patent number: 10764279
    Abstract: Embodiments herein relate to a method and an information appliance device having a unique access card for preventing security breach in the information appliance device. A multimedia content server transmits a one-time access key to both the information appliance device and a user of the information appliance device. The user must input the access key to the information appliance device. The information appliance device verifies the access key and provides access to the user for the multimedia services, by activating a periodic activation key upon successful verification of the access key. Therefore, even if unauthorized user tries to skip the access key verification process through modification of access cards used in information appliance device, the unauthorized user cannot access the multimedia service due to lack of the periodic activation key required for activating multimedia service. Hence, security breach such as, cloning or duplication of the access cards will be minimized.
