Problems solved by technology

[0004] However, the upper end surface of the Z-shaped block 41 must be ground into a flat and smooth surface to be coated, so that the processing cost is very expensive, and the optical multiplexer / demultiplexer 40 does not have market competitiveness. Therefore, a cost Low and easy-to-process multiplexer
[0005] In addition, optical signals must pass through the Z-shaped block 41 for optical signal transmission, thus causing loss of optical signals, which need to be resolved

Embodiment Construction

[0020] see Figure 2 to Figure 7 As shown, the optical multiplexer / demultiplexer 10 of the present invention includes a multiplexer body 11, a reflector 20, and a plurality of filters 30a, 30b, 30c, 30d. The multiplexer body 11 includes an upper substrate 12 and a lower substrate 13; the reflector 20 and a plurality of filters 30a, 30b, 30c, 30d are connected between the upper substrate and the lower substrate 12, 13, so that the upper substrate, A chamber 14 is formed between the lower substrates 12 and 13 . When the optical signals of different wavelengths transmitted from the outside enter the optical multiplexer / demultiplexer 10, each of the optical signals will be combined / separated in the chamber 14 to become a single beam (multiplexing) or separate out different optical signals. wavelength (demultiplexing). In terms of an optical multiplexer, it utilizes the reflector 20 to reflect to each of the filters 30a, 30b, 30c, and 30d for demultiplexing, so that optical signa...

The optical multiplexer / demultiplexer comprises a reflective lens, a plurality of filters, and a multiplexer body, wherein the multiplexer body comprises an upper substrate and a lower substrate, the reflective lens and the plurality of filters are connected between the upper substrate and the lower substrate, and a chamber is formed between the upper substrate and the lower substrate; and when optical signals with different wavelengths enter the optical multiplexer / demultiplexer, the optical signals are combined / separated inthe chamber.

Description

technical field [0001] The invention relates to an optical combiner / demultiplexer of an optical fiber transmission system. Background technique [0002] The current optical fiber transmission system relies on the principle of optical multiplexing / demultiplexing, so that different wavelengths share a single optical fiber, and multiple optical signals of different wavelengths are transmitted in the same optical fiber, and each signal is carried by its own different optical wavelength. [0003] Usually the principle of optical multiplexing / demultiplexing is to use optical multiplexing / demultiplexing multiplexers as optical fiber transmission methods, such as figure 1 As shown, the optical multiplexer / demultiplexer 40 includes a Z-shaped block (Z-BLOCK) 41, which is made of optical glass, has an upper end face and a lower end face, and the upper end face is coated with a reflective film 42 and a Anti-reflection film 43; Most filters 44a, 44b, 44c, 44d are installed on the lower...
