Embodiment Construction

[0015] see Figure 2 to Figure 4 As shown, the optical multiplexer / demultiplexer 10 provided by the present invention can combine multiple optical signals of different wavelengths into a single light beam (multiplexing) or separate out different wavelengths (demultiplexing). The optical multiplexer / demultiplexer 10 is composed of a Z-shaped frame 11, a reflective film lens 20 and a plurality of filters 30a, 30b, 30c, 30d. The main feature of the optical multiplexer / demultiplexer 10 provided by the present invention is that the Z-shaped frame 11 has an upper end surface 12 , a lower end surface 13 and an optical channel 14 leading from the upper end surface 12 to the lower end surface 13 .

[0016] The upper end surface 12 can be used to install the reflective film lens 20; the lower end surface 13 can be used to install the plurality of filters 30a, 30b, 30c, 30d; the present invention is implemented with a multiplexer and four different wavelength optical signals As an examp...

Abstract

The invention discloses an optical wave combining / dividing multiplexer comprising a reflecting film lens, a plurality of filters, and a Z-shaped frame. The Z-shaped frame has an upper end face, a lower end face and an optical channel leading to the lower end face from the upper end face. The upper end surface can be used for mounting the reflective film lens; the lower end surface can be used formounting the plurality of filters; and optical signals having a plurality of different wavelengths are combined / separated in the optical wave combining / dividing multiplexer.

Description

technical field [0001] The invention relates to an optical combiner / demultiplexer of an optical fiber transmission system. Background technique [0002] The existing optical fiber transmission system uses 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] Generally, 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 made of optical glass, which has an upper end face and a lower end face, and the upper end face is coated with a reflective film 42 and an anti- A reflective film 43; a plurality of filters 44a, 44b, 44c, 44d are installed on...
