Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that there is no all-ceramic wavelength division multiplexer product on the market at present. The positioning in the center is not as accurate as the positioning in the special-shaped inner hole, resulting in a substantial increase in the insertion loss and return loss of the optical fiber, and the problem that it is impossible to produce a high-precision all-ceramic wavelength division multiplexer. A kind of all-ceramic wavelength division multiplexer is provided. and its preparation method

Abstract

The invention provides an all-ceramic wavelength division multiplexer and a production method thereof; the all-ceramic wavelength division multiplexer has a sleeve, a single-core fiber collimator and a double-core fiber reflector are mounted in the sleeve, all the sleeve of the wavelength division multiplexer, a sleeve of the single-core fiber collimator and a sleeve of the double-core fiber reflector are of ceramic, a single insert core of the single-core fiber reflector is a circular microporous ceramic insert core, and a double insert core of the double-core fiber reflector is a special-deformed microporous ceramic insert core; the defect that a traditional glass wavelength division multiplexer is fragile and difficult to process is overcome; the process of the all-ceramic wavelength division multiplexer of the invention is simple, high in production efficiency and low in manufacture cost, and the all-ceramic wavelength division multiplexer has the advantages of low insertion loss, high echo loss, good reliability and the like and is easier to process, lower in cost, better in uniformity, less prone to ambient influence and higher in reliability as compared with traditional glass wavelength multiplexers; the wavelength multiplexer produced by using the method has transmission insertion loss of 0.35 dB and below.

Description

technical field [0001] The invention belongs to the technical field of optical device manufacturing, and in particular relates to an all-ceramic wavelength division multiplexer and a preparation method thereof. Background technique [0002] Wavelength division multiplexing technology is a technology that combines two or more optical carrier signals of different wavelengths (carrying various information) at the sending end through a multiplexer, and couples them to the same optical fiber of the optical line for transmission; At the receiving end, the optical carriers of various wavelengths are separated by the demultiplexer, and then further processed by the optical receiver to restore the original signal. This technology of simultaneously transmitting two or more optical signals of different wavelengths in the same optical fiber is called wavelength division multiplexing. [0003] Wavelength division multiplexers are widely used in the fields of telecom operators, radio and...
