Problems solved by technology

[0003] With the construction of 5G network, optical modules are used in various transmission nodes, but the efficiency of the existing optical modules in transmitting optical signals is relatively low, and the multiplexing of optical fiber channels in optical modules cannot be effectively improved. This increases the cost of many network construction

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] Such as figure 1 As shown, the function, node structure and its products and applications of the existing OADM system based on WDM technology, the branch signal of its add-drop multiplexing is called an optical channel in units of wavelength. The OADM device is one of the key node devices of the all-optical network.

[0044] A WDM signal contains channels of multiple wavelengths, and these channels are multiplexed and transmitted in an optical fiber, a...

Abstract

The invention provides an optical module device and an optical fiber capacity expansion system. The optical module device comprises a light-emitting secondary device with a narrow-band filter, a lightreceiving secondary device with a narrow-band filter, an emitting circuit device and a receiving circuit device, the transmitting circuit device is connected with the light-transmitting secondary device with the narrow-band filter; the light-emitting secondary device with the narrow-band filter is connected with the light receiving secondary device with the narrow-band filter; and the receiving circuit device is connected with the light receiving secondary device with the narrow-band filter. The OADM function is integrated on the optical module, networking is optimized, the engineering installation difficulty is reduced, the network construction cost is saved, and the optical fiber wavelength transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of optical signals, in particular to an optical module device and an optical fiber expansion system. Background technique [0002] To transmit optical signals in the existing optical fiber, OADM (Optical Add-Drop Multiplexer) technology will be used for transmission. The general OADM node can be represented by a four-port model. The basic functions include three types: figure 1 As shown, the wavelength channels required by the drop are multiplexed into the add signal, so that other wavelength channels can pass through as unaffected as possible. The specific working process of OADM is as follows: the WDM signal from the line contains N wavelength channels, and enters the "Main Input" end of OADM. According to business requirements, from the N wavelength channels, selectively output the required correspondingly input the required wavelength channel from the add end. Other wavelength channels that have nothing to do wi...
