OPTICAL LINE TERMINAL (OLT) DEVICE AND OPTICAL PATH PROCESSING METHOD

Title:

OPTICAL LINE TERMINAL (OLT) DEVICE AND OPTICAL PATH PROCESSING METHOD

Document Type and Number:

WIPO Patent Application WO/2022/001584

Kind Code:

A1

Abstract:

The present application provides an optical line terminal (OLT) device and an optical path processing method. The OLT device comprises a first downlink interface, a photoelectric conversion unit, and an optical path processing module. The photoelectric conversion unit comprises a first optical port and a second optical port. The first downlink interface is connected to the first optical port and the second optical port by means of the optical path processing module. The optical path processing module is configured to enable a first optical path between the first downlink interface and the first optical port or enable a second optical path between the first downlink interface and the second optical port. An optical path that can be enabled is established between one downlink interface of the OLT device provided in the present application and at least two optical ports of the photoelectric conversion unit, so that an impact on services of user devices caused by a fault of a downlink interface can be avoided, and the reliability and applicability of the OLT device are improved.
