Embodiment Construction

[0017] Embodiments of methods, devices, and systems for communication between two endpoints over an optical distribution network are described herein.

[0018] image 3 An example implementation of the solution in a communication system is shown. exist image 3 In this communication system, two or more wireless base stations are connected to the ODN and communicate with the wireless core network through the OLT on standard TWDM-PON wavelengths, and communicate with each other via overlay wavelengths. The ONUs connected to each base station are augmented with transmitters and receivers operating outside the TWDM-PON or NG-PON2 wavelength spectrum. This spectrum is preferably within the range allocated for WDM transmission. Therefore, we will proceed to refer to these ONUs as WDM ONUs.

[0019] The PON function of the WDM ONU remains unchanged and is active in parallel with the WDM overlay function. Parallelism can be achieved by splitting the optical input light between th...

Abstract

A method for communication between two endpoints (300), (302) over an optical distribution network (314) where the endpoints are connected to the optical distribution network over optical network units (304), (306). These optical network units are connected to at least one optical routing element (312). The optical network units and the at least one optical routing element are controlled by an optical controller (310). The two endpoints are controlled by a wireless controller (308). A communication request between the two endpoints is created (400) by the wireless controller. The communicationrequest is sent (402) from the wireless controller to the optical controller. Further the optical controller identifies (404) the optical network units connected to the two endpoints. The optical controller checks (406) if the optical network units belong to the same optical distribution network and configures (408) the optical network units to transmit and receive a first wavelength spectrum andthe at least one optical routing element to route the first wavelength spectrum. The optical controller requests (410) the wireless controller to establish the communication between the two endpointsover the optical distribution network.

Description

technical field [0001] The present application relates generally to optical networks, and more particularly to systems, apparatus, and methods for endpoint communication over optical access networks. Background technique [0002] The invention is applicable to the field of optical networks, such as optical access networks, where the optical fiber medium follows a tree topology. figure 1 An example of an optical access network based on a passive optical network (PON) is illustrated. It shows an architectural diagram of a PON implementation where at the central office location the network provider operates the active network equipment comprising four different OLTs operating in multiplexed to one optical fiber Four different wavelengths λ1-λ4. The optical distribution network forms the domain of the fiber optic infrastructure and may be managed by an infrastructure provider different from the network provider. Such networks facilitate the delivery of telecommunications serv...
