Description
Technical Field
The utility model relates to an optical network equipment field, in particular to light wavelength division multiplexing system specifically is a modular DWDM module.
Background
In the current optical network system, the output fiber of the passive wavelength division multiplexing module is divided into a tail fiber type and a flange type. Wherein the pigtailed module is generally placed in the device for use. The flange type is generally a machine box type, a drawer type and the like which are used with a machine cabinet. The package size of the pigtail module is most often customized to fit the installation requirements of the equipment manufacturer (fig. 7). The flange module mainly comprises a machine box type, a drawer type and a plug-in sheet type. Wherein the machine box type and the drawer type have larger volume and occupy the space of the machine room. The patch type has been widely applied to communication operators, but is limited to an optical splitter module and a coarse wavelength division multiplexing CWDM module at present. With the construction and application of the subsequent 5G communication, the DWDM with high density and multiple channels has wider application range.
Disclosure of Invention
The object of the present invention is to provide a high density, standardized, low cost module that can be used in DWDM passive transmission equipment packaging.
In order to achieve the above object, the present invention is realized as follows:
a modularized DWDM module comprises a DWDM module body, a plug-in sheet type packaging box and an interface module; the plug-in type packaging box is of a shape and size with a telecommunication industry standard and is used for being installed in an existing cabinet type chassis and a wall-hanging type chassis, the interior of the plug-in type packaging box is hollow, a gap is also formed in the side face of the plug-in type packaging box, an ear plate for installation and connection is arranged on the side portion of the plug-in type packaging box, and the DWDM module body is arranged in the plug-in type packaging box and is connected with the outside through an interface module arranged on the gap in the side face of the plug-in type packaging box.
In the modularized DWDM module, the output interface of the interface module is an SC-shaped duplex LC adapter interface.
The DWDM module of modularization, DWDM module are that three port DWDM devices splice and form, and its wire jumper is the wire jumper of appointed pattern.
The utility model discloses the used adoption has standard overall dimension's box body, extends the DWDM module to make it become a standardized, be convenient for and the DWDM module that has abundant extended functionality with current equipment fixing.

Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1 and 2, a modular DWDM module; wherein, the size and structure of the used standard plug-in box 1 must conform to the telecommunication standard, and the plug-in box 1 can be matched with the existing chassis for use.
As shown in fig. 3, a three-port DWDM device 2 is a cascadable glass tube packaged device made using the interference thin film filter principle.
As shown in fig. 4, the adapter 3 (i.e., interface module) is an LC/PC duplex adapter with ears, conforming to the SC adapter opening shape.
As shown in fig. 5, the connector of the interface module is a standard LC/PC connector.
The packaging process for 1-division 16-wave DWDM modules using the above structure comprises the following steps:
1. selecting packaging boxes according to the number of the channels;
2. the LC/PC duplex adapter 3 is loaded into the single layer card housing 1, the ears of the adapter 3 are inserted into the slots of the card housing 1, and glue is added into the slots for fixation, as shown in FIG. 6.
3. Selecting the DWDM three-port device 2 of the corresponding channel as required, as shown in fig. 3;
4. the DWDM three-port devices 2 selected in step 3 are placed at the bottom of the standard single-layer card cage shown in fig. 1, stacked at a certain position, and spliced into a module according to a specific application, and the connectors of the corresponding ports are inserted into the corresponding flanges on the panel, as shown in fig. 8 (the black squares in the figure represent the stacked parts of the three-port devices).
The utility model discloses an in the application, 2 minimum passageways can be followed to 32 passageways at most to the passageway number of DWDM module, and 2~16 passageways use the individual layer plug-in card case, and 17~32 passageways use double-deck plug-in card case. Vacancies with a non-full number of channels can be filled with special dummy bars. The packaging structure meets the standard of the existing cabinet mounting structure, is plug-and-play, and is easy to mount.
