Problems solved by technology

[0004] The above-mentioned optical module mainly has the following shortcomings in practice. First, it adopts the design of the optical converter 4 to change the transmission direction of the optical path, which not only has a complex structure and low processing efficiency, but also increases the loss of optical energy during transmission. Second, , the matching precision required between the various components is high, the production technology is difficult and the cost is high. Third, due to the optical path design of the optical lens and optical mirror, the coupling process is complicated, resulting in low coupling accuracy and efficiency of the overall product

example 1

[0064] Example 1: L=150μm, D1 / D2=0.8 (D2 / D1=1 / 0.8), D2=750μm, the total length of the plastic optical fiber 30 is less than 0.016 meters, (2mm / 150μm)*(1 / 0.8)*10 -750μm / 250μm m = 0.016 m.

example 2

[0065]Example 2: When L=50 μm, D1 / D2=0.9 (D2 / D1=1 / 0.9), D2=500 μm, the total length of the plastic optical fiber 30 is less than 0.44 meters, (2mm / 50 μm) *(1 / 0.9)*10 -500μm / 250μm m = 0.44 m.

example 3

[0066] Example 3: (the most typical application parameters) when L=100μm, D1 / D2=0.95 (D2 / D1=1 / 0.95), D2=250μm, the total length of the plastic optical fiber 30 is less than 2.11 meters, (2mm / 100μm) * (1 / 0.95)*10 -250μm / 250μm m = 2.11 m.

[0067] The design idea of ​​the plastic optical fiber 30 in the present invention is as follows: First, the functional optical modules 21 on the control circuit board 20 are all placed horizontally, and the glass optical fiber (GOF) 1 will break when bent, so in order to realize the transmission of optical signals, Then it is necessary to increase the optical converter 4, and the addition of the optical converter 4 will inevitably increase the cost of the product, and will also greatly increase the volume of the product. The biggest advantage of using glass optical fiber (GOF) 1 for optical transmission lies in long-distance optical transmission. The signal attenuation is weak, but in practical applications, most signal transmissions are com...
