Example Embodiment

Example one:

The structure diagram of a specific embodiment of the present invention is shown in FIG. 4, the transmitting end 1 and the receiving end 2 are placed side by side, and the principle of the optical path is shown in FIG. 5, and the optical path propagates through the optical lens group 3. The optical lens group 3 includes a first total reflection glass plate 31, a focusing lens 34, a second total reflection glass plate 33, and a filter 32. The first total reflection glass plate 31 and the second total reflection glass plate 33 are placed in parallel, a focusing lens 34 is placed between the two, the first total reflection glass plate 31 is placed at an angle of 45 degrees to the incident light direction, and the second total reflection glass plate A filter 32 is placed between the glass slide 33 and the receiving end 2, and the filter 32 can also be placed between the first total reflection glass plate 31 and the second total reflection glass plate 33. When transmitting...

Example Embodiment

Embodiment two:

Fig. 7 is a divergence diagram of the optical path when the focusing lens 34 is not added in the specific embodiment of the present invention. Under the structure of two total reflection glass slides in this example, the laser can reach the receiving end after two total reflections and one filtering. The stroke in the air is greatly increased, so that the power of the laser suffers a greater loss, and due to the long divergence distance, the average area power is reduced, which is inferior to the solution of the first embodiment in terms of receiving sensitivity.

The single-fiber bidirectional module of the present invention fully meets national and international standards in terms of main performance such as power and sensitivity, and is completely compatible with the current SFP standard module in appearance, and achieves miniaturization while ensuring performance.

Abstract

The invention comprises: a transmitting end, a receiving end and an optical lens group. Said transmitting end and receiving end are set in parallel. Said optical lens group comprises a first fully-reflecting glass-slide and a second fully-reflecting glass-slide; said first fully-reflecting glass-slide and second fully-reflecting glass-slide are set in parallel for use in guiding the incident light to said receiving end.

Description

technical field The invention relates to optical fiber communication network equipment, in particular to a single-fiber bidirectional photoelectric transceiver integrated assembly. Background technique With the application of fiber optic networks becoming more and more popular, especially the gradual implementation of Fiber To The Home (FTTH) projects around the world, the market demand for small form-factor pluggable (SFP) packaged single-fiber bidirectional components is also increasing. gradually increase. However, due to the relatively large size of the traditional structure of the single-fiber bidirectional component, there is a conflict with the small-size package of the SFP, and the method of increasing the size of the connection port is usually used to solve the problem. The sudden enlargement of the connection end not only makes the appearance unattractive, but also greatly increases the probability of collision damage with the outside world. The structure of th...
