OLT (Optical Line Terminal) equipment and optical path processing method

Abstract

The invention provides optical line terminal (OLT) equipment and an optical path processing method. The OLT equipment comprises a first downlink interface, a photoelectric conversion unit and an optical path processing module, wherein the photoelectric conversion unit comprises a first optical port and a second optical port. And the first downlink interface is respectively connected with the first optical port and the second optical port through the optical path processing module. And the optical path processing module is used for starting a first optical path between the first downlink interface and the first optical port or starting a second optical path between the first downlink interface and the second optical port. According to the OLT equipment provided by the invention, the optical path which can be enabled is established between the downlink interface and the at least two optical ports of the photoelectric conversion unit, so that the service influence on the user equipment caused by the fault of the downlink interface can be avoided, and the reliability and applicability of the OLT equipment are improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to an optical line terminal (optical line terminal, OLT) device and an optical line processing method. Background technique [0002] With the continuous development of communication technology, the application of optical communication technology is becoming more and more extensive. At the same time, in the optical communication network established based on the optical communication technology, the traditional network access system is gradually replaced by an optical access network (optical access network, OAN) system. Passive optical network (PON) is an implementation technology of optical access network, and PON is an optical access technology for point-to-multipoint transmission. See figure 1 , figure 1 It is a schematic diagram of a PON system architecture provided by the embodiment of this application. Such as figure 1 As shown, the optical line terminal (optical lin...

AI Technical Summary

Problems solved by technology

However, the replacement of the downlink interface needs to transfer all the user equipment on the failed downlink interface to the new downlink interface, which will still cause a large delay in the service of the user equipment due to the interface replacement

Therefore, the reliability and applicability of existing OLT equipment are poor
