摘要： The techniques described herein are directed to an in-line diagnostic tool of a PON that optically couples a first component of the PON and a second component of the PON. The tool detects incoming optical signals (e.g., of different services) received from the first PON component and passes the optical signals through the tool to the second PON component. The in-line diagnostic tool is configured to detect one or more conditions of the incoming optical signals, the PON, and/or sub-components of the tool, perform one or more diagnostic and/or analytics routines, and generate and transmit a diagnostic signal including information indicative of the detected conditions and/or the results of the diagnostic and/or analytics routines to be transmitted via one or more output interfaces of the in-line diagnostic tool to recipient devices and/or applications.

摘要： Embodiments including methods, systems, and apparatuses for distributing, processing, and reacting to path information distributed via a service-agnostic packet fabric for the purpose of enabling path selection are disclosed. By configuring two ingress line cards to send path quality words to each other via the switch fabric, compare the path quality words, and determine whether to transmit traffic to an egress line card via the switch fabric based on the comparison of the path quality words, the embodiments enable a central switch fabric to be unaware of the paths that it carries, and enable both ingress and egress bandwidth of the switch fabric to be sized according to the facilities for which it is terminating. The switch fabric does not need to support working and protection paths simultaneously in some embodiments, allowing it to be scaled appropriately to termination facilities.

摘要： Embodiments of the present invention provide an access system and a communication method for an optical fiber network. A virtual ONU located on a user side is established, and an ONU control plane function, a PON MAC function, and a QoS function on an existing ONU is moved downwards to a virtual ONU. After the forgoing function modules are removed from the existing ONU, the existing ONU becomes an ONU physical converter and only has a function of converting the PON physical layer frame and the first user side physical layer frame.

摘要： Optical networking has become ubiquitous in providing low cost, high speed communications networks supporting our communication needs from FTTH through long haul to undersea. The large number of users and high speeds provided to each user fiber mean that information retrieval and routing functionality within the data centers hosting this information can become the bottleneck both in terms of speed and latency. According to embodiments of the invention the inventors present architectures based upon all-optical passive optical networks that support a distributive approach to latency reduction as well as protocols relating to their deployment. Beneficially, such POCXN concepts exploit optical components already supported by high volume manufacturing techniques as well as CWDM/DWDM techniques for throughput increase.

摘要： An optical network transmits a wavelength division multiplexing optical signal from a transmission to a reception node via a reconfigurable optical add/drop multiplexer and/or path cross-connect apparatuses. When optical or optical super channels made of successive optical subcarriers input from input optical fibers are routed or switched to an output optical fiber in the multiplexer and/or apparatus passed through by a wavelength division multiplexing optical signal transmitted from the predetermined transmission node to the predetermined reception node, the adjacent channels output to the same output fiber in each input fiber is collectively demultiplexed without being demultiplexed for the channels and is routed or switched to the output fiber. Channel routing paths and frequency arrangements are controlled such that the number of filtering times by a wavelength division filtering mechanism on one or both sides on the frequency axis of the channel becomes equal to or less than a predetermined value.
