Abstract
The invention discloses a manufacturing method of 18ch-high-isolation dense wavelength division multiplexing products. The manufacturing method comprises the following steps that (1) raw materials, process equipment and testing equipment are prepared; (2) a double-optical-fiber head and a single fiber collimator are connected by gluewater, then, a small glass tube is adhered at two sides of the double-optical-fiber head, and a large glass tube is adhered on the single fiber collimator; (3) finally, a G-Lens lens and a filter plate are adhered on a device, and the device assembly is completed after the gluewater is dried in the air. The manufacturing method has the advantages that double diaphragms are adopted for increasing the isolation degree, the frequency-selection characteristic of a wavelength division multiplexing device is improved, the mutual interference among all multiplexing optical channels is reduced, and the transmission capability of a system is greatly improved.
Description
Technical field
The present invention is specially a kind of dense wave division multipurpose production method of 18ch high-isolation.
Background technology
In recent years, global communications market develops rapidly, especially the rise of a series of new business such as Internet, high-quality TV conference system and multimedia, demand to large capacity, high performance network transmission increases severely, and traditional fibre-optic transmission system (FOTS) adopts " a fine ripple " mode, owing to being subject to the restriction of device self-characteristic, its transmission capacity and dilatation way all cannot satisfy the demands, and the enormous bandwidth resource of optical fiber not yet makes full use of simultaneously.A kind of new transmission technology---close wavelength-division multiplex technology (DWDM) becomes effective, the most most economical means of optical fiber dilatation.DWDM technology is with its exclusive technical advantage, become the approach that energy is rapid, simple, economic, effectively expand Optical Fiber Transmission capacity, can fully meet the demand of current network broadband business development, yet because of its channel spacing very narrow, so just isolation is had to very high requirement, the isolation of path is higher, and the selecting frequency characteristic of wavelength division multiplex device is just better; Its clutter reduction is larger than also, and the mutual disturbing effect between each multiplexed optical path is also just less, and the transmittability of system is just better.
Summary of the invention
Technical matters solved by the invention is to provide a kind of dense wave division multipurpose production method of 18ch high-isolation, to solve the problem proposing in above-mentioned background technology.
In order to achieve the above object, the present invention realizes by the following technical solutions: a kind of dense wave division multipurpose production method of 18ch high-isolation, comprises the following steps:
(1) prepare starting material, process equipment and testing apparatus;
(2) use glue that double optical fiber head and single fiber collimating apparatus are coupled together, then cuvette is sticked in to double optical fiber head both sides, large glass tube sticks in single fiber collimating apparatus;
(3) finally G-Lens lens and filter plate are sticked on device, after glue is air-dry, complete device assembling.
Further, the starting material described in step (1) are filter plate, double optical fiber head, single fiber collimating apparatus, large glass tube, cuvette, G-Lens lens and glue.
beneficial effect:
The inventive method adopts two diaphragms to increase isolation, improves the selecting frequency characteristic of wavelength division multiplex device, reduces the phase mutual interference between each multiplexed optical path, has greatly improved the transmittability of system.
