    摘要： An optical interconnection assembly and method for the deployment and scaling of optical networks employing Spine-and-Leaf architecture has Spine multi-fiber optical connectors and Leaf multi-fiber optical connectors. The Spine optical connectors of the interconnection assembly are optically connected to multi-fiber connectors of Spine switches via Spine patch cords. The leaf multi-fiber connectors are optically connected to Leaf multi-fiber connectors of Leaf switches via Leaf patch cords. A plurality of fiber optic cables in said interconnection assembly serves to optically connect every Spine multi-fiber connector to every Leaf multi-fiber connector so that every Spine switch is optically connected to every Leaf switch. The optical interconnection assembly facilitates the deployment of network Spine-and-Leaf interconnections and the ability to scale out the network by using simplified methods described in this disclosure.

    摘要： Embodiments of this application disclose an optical distribution network ODN apparatus and a signal processing method, to transmit information such as identification information of a plurality of ONUs and port identification information of the ODN apparatus to an OLT. The information such as the identification information of the plurality of ONUs and the port identification information is used by the OLT to determine network topology information of a PON system. The ODN apparatus includes an optical splitting module, a control chip, a first optical port connected to the OLT, a second optical port connected to a next-level ODN apparatus, and a plurality of third photoelectric composite ports connected to the plurality of ONUs. The control chip separately sends a plurality of electrical signals that carry the port identification information to the plurality of corresponding ONUs. The optical splitting module performs power splitting on a first optical signal sent by the OLT to obtain a second optical signal transmitted to the next-level ODN apparatus and a plurality of third optical signals transmitted to the plurality of ONUs. The optical splitting module is further configured to: separately receive upstream optical signals of the plurality of corresponding ONUs, and transmit the upstream optical signals to the OLT, where the upstream optical signals carry identification information of the ONUs that send the upstream optical signals and corresponding port identification information.
