Manufacturing method of 18ch-high-isolation dense wavelength division multiplexing products with

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 [0001] The invention is specifically a method for manufacturing a dense wavelength division multiplexing product with 18ch high isolation. Background technique [0002] In recent years, the rapid development of the global communication market, especially the rise of a series of new services such as the Internet, high-quality video conferencing systems, and multimedia, has sharply increased the demand for large-capacity, high-performance network transmission, while the traditional optical fiber transmission system uses Due to the limitations of the device's own characteristics, the "one fiber, one wave" method cannot meet the needs of its transmission capacity and expansion method, and at the same time, the huge bandwidth resources of optical fibers have not been fully utilized. A new transmission technology - Dense Wavelength Division Multiplexing (DWDM) has become the most effective and economical means of fiber expansion. With its unique technical advanta...
