Fig. 2 is multiport wavelength-division transceiver light splitting optical path structural schematic diagram provided by the embodiment of the utility model.
Specific embodiment
For convenient for those skilled in the art understand that the utility model technology contents, with reference to the accompanying drawing to the utility model
Content is further illustrated.
It is illustrated in figure 2 a kind of multiport transceiver light splitting optical path structural schematic diagram provided in this embodiment, the application
Technical solution are as follows: a kind of multiport transceiver optical device includes at least one group of spectrum groupware, one group of spectrum groupware corresponding two
A port, the spectrum groupware includes two pieces and is obliquely installed and the consistent filter plate of inclined direction in equal angular, and is located at
Parallel flat between filter plate；
One group of corresponding two receiving light path of spectrum groupware and two transmitting optical paths.
Below by taking one group of spectrum groupware as an example, the multiple receiving ends of separation, the multiple transmitting terminals of separation and separation are received respectively
The realization principle of hair these three situations of Hybrid port is illustrated.
1, multiple receiving ends are separated
As shown in Fig. 2, light is incident on optical filter 1 by parallel flat from left side incidence, need to do port separation at this time
Wavelength light is reflected by optical filter 1, is incident on optical filter 2 by parallel flat, optical filter 2 by the corresponding wavelength light transmission in port 1,
The wavelength light is received by port 1；Filter plate 2 reflects the corresponding wavelength light in port 2, reflects through parallel flat, is connect by port 2
It receives.
The port entirely separated in this way is not vertical with chief ray.It in this way can be with reduced width space.
2, multiple transmitting terminals are separated
