A manner of managing data transmission and operating-mode transitions in a communication network. A network node having a transmitter and receiver is selectively transitioned into a Transmit state, where the Transmit state is a condition wherein the transmitter is turned on for data transmission only during timeslots provided for by a PBW (pre-allocation bandwidth) and remains off otherwise. The PBW and clock drift allowance permits the receiver to remain off during all or most of the Transmit state.

The present invention is a system and method for automating several processes that are presently time-consuming and labor intensive projects, and more specifically, the invention is a system and method implemented by a computer-based tool that enables a user to bring multiple cables (202) together and illustrate in a graphical manner the splices between individual fibers (206) in multiple tubes (204) within multiple cables (202).

Systems and methods are disclosed for configuring a communications network. In disclosed embodiments, for a communication network comprising fiber optic cables connected by switches and transceiver-transponders, a graph representing the communication network can be obtained with edges representing the fiber optic cables, and nodes representing the switches and transceiver-transponders. A set of service links can be determined for a path in the communication network based on a set of demands for the path. Each service link can represent data transmission by one of the transceiver-transponders through one or more of the fiber optic cables connected by zero or more of the switches. Sets of service links can be iteratively selected for progressively longer initial segments of the path. When the initial segment comprises the path, the set of service links for the initial segment can be selected as the set of service links for the path.

An optical network includes an arrangement of optical nodes. An optical node of the arrangement, and corresponding method, perform optical connectivity discovery and negotiation-less optical fiber continuity verification in the optical network. An overall topology of optical connectivity provisioned for the arrangement is discovered by the optical node based on messages received from a management network communicatively coupling the optical nodes to each other. The optical node synchronizes, temporally and sequentially, with the other optical nodes based on the messages received, assigns fiber of the overall topology, based on a verification sequencing method, to verification slots of a verification sequence, and verifies continuity of fiber according to the verification slots of the verification sequence. The discovery, synchronization, and assignment operations enable the optical node and peer node to perform the optical fiber continuity verification in a symmetric, decentralized, and negotiation-less manner.

Embodiments of the present application provide a method and apparatus for opening a quiet window, and a registration method, apparatus and system. The method for opening a quiet window includes that: a first quiet window is opened when it is determined that the first quiet window needs to be opened, wherein the first quiet window is used for Optical Network Unit (ONU) discovery. According to the embodiments of the present application, a first quiet window is opened only when it is determined that the first quiet window needs to be opened, rather than periodically opening the first quiet window, such that the efficiency of the first quiet window is improved and the impact of the first quiet window on a data transmission delay is reduced, thereby reducing a transmission delay of a Passive Optical Network (PON) system.
