Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0021] At present, most of the optical network units in the user's home are PON (Passive Optical Network, passive optical network). The optical network unit is integrated with a PON optical module, and the PON function of the optical network unit is realized through the PON optical module. If some users need to access CATV (Community Antenna ...

Abstract

The invention discloses a video receiving optical module and an optical network unit, the optical module comprises a PCB, a first optical fiber interface and a second optical fiber interface, the PCBis provided with an optical receiving assembly, and the first optical fiber interface and the second optical fiber interface are respectively connected with the input end of the optical receiving assembly through optical fibers; the light receiving assembly comprises a filter and a light receiving device, and CATV light input through the first optical fiber interface is received by the light receiving device through the filter; downlink PON light input through the first optical fiber interface is reflected to the second optical fiber interface by the filter. The video receiving optical moduleprovided by the invention can be flexibly inserted into the optical network unit, and when the CATV needs to be accessed, the CATV function of the optical network unit can be realized only by inserting the video receiving optical module into the optical network unit; when the CATV does not need to be accessed, only the video receiving optical module needs to be dismantled, the optical network unitdoes not need to be replaced, the application is flexible, and the user experience is greatly improved.

Description

technical field [0001] The present application relates to the technical field of optical communication, in particular to a video receiving optical module and an optical network unit. Background technique [0002] The optical modem is an optical modem, which is a three-piece set of optical transmission equipment developed for special user environments. The equipment uses a large-scale integrated chip with simple circuits, low power consumption, high reliability, and complete alarm status indication. And perfect network management function. Most optical cats are connected to PON (Passive Optical Network, passive optical network), and can also be connected to CATV (Community Antenna Television, cable TV network) as required. [0003] There are two types of optical modems for conventional access-type CATV applications. One is the plug-in three-way optical module plugged or welded on the optical modem. The core device of the three-way optical module is a three-way optical compon...
