Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As it is shown in figure 1, the Compact multi-channel light wavelength division multiplexing of a kind of low cost high efficiency of the present utility model,
Including a common wavelength channel fiber collimator 1, N number of Single wavelength channel fiber collimator 2 and N number of Single wavelength channel fiber
The filter plate 3 that collimator 2 one_to_one corresponding is arranged；It is characterized in that, also including substrate 4 and Z rhombic prism 5, described substrate 4 is recessed
Shape, limit wall symmetrical around is provided with the cylindrical hole for fixing each collimator, and the centre of substrate 4 is provided with for fixing Z oblique
The groove of square glass prism 5, the depth of groove in the middle of substrate 4 is less than the thickness of Z rhombic prism 5, i.e. the thickness of Z rhombic prism 5 exceeds
The surface of substrate intermediate groove, exceeds on Z rhombic prism 5 and directly pastes filtering on the left and right side on substrate intermediate groove surface
Sheet, the cylindrical hole on the wall of limit is coaxially distributed with the filter plate being correspondingly arranged.
This utility model light wavelength division multiplexing in use, as it is shown in figure 1, each collimator 1 is fixed on the wall of substrate 4 limit
In cylindrical hole, filter plate 3 directly sticks in the middle of substrate on the left and right side of Z rhombic prism 5, the corresponding manifold of each filter plate 3
A wave band in road optical signal, and a corresponding Single wavelength channel fiber collimator 2 of filter plate 3, pasting of filter plate 3
Position is determined by the incident angle of light of each collimator.Operation principle of the present utility model is, common wavelength channel fiber collimator 1
