The optical signal of the fiber is not very strong and will not be weakened. Why do I need an optical repeater? Is this not the case? Things are not your idea, the light in the fiber will be weakened. Since the material inside the fiber does not reflect light perfectly, there is some degree of scattering and absorption. Therefore, the relay amplifier cooperates with the design of multiple fibers built into the cable and then transmits multiple different data streams on a single fiber. A general solution to this weakened signal is to use a repeater.

In addition, most advanced optical networks use an infrared band with a relatively low frequency, which means that it cannot carry as much information as higher energy and higher frequency radiation.

In general, if you want to increase the information transmission speed of the fiber, you can make the cable thicker or use a higher frequency to accelerate. But of course, it is also necessary to consider the feasibility of cost in real life. Signal strength, power consumption and safety issues also need to be considered.

The above information is shared by the Fiber Closure manufacturer and hopes to help those in need.
