    Opway teaches you how to calculate the link budget
    A

    Many customers may be confused about the calculation of the optical link budget. Here is how to calculate it. Optical link budget refers to the effective distance of optical signal transmission. There are three main factors; 1、Transmitting optical power of the transmitting end; 2、Receiving sensitivity of the receiving end; 3、Optical fiber attenuation coefficient; Calculation formula: link budget L=(Ps-Pr-Me-Ac)/(Af+As+Mc)(km) Ps:...

    The history of optical module development
    A

    Before the 1990s, optical modules were all designed and manufactured by equipment manufacturers. The dimensions and electromechanical interfaces were all based on the feelings of engineers, and there was no compatibility at all. This caused many problems in the interconnection of operators. In the mid-1990s, operators and major equipment vendors got together to form the MSA organization, which promoted the standardization of optical modules, and o...
