Can stacked cables replace optical modules
There are differences in functions and transmission methods between stacking cables and ordinary optical fibers, so stacking cables cannot directly replace ordinary optical fibers. An optical module is a photoelectric conversion device that can convert electrical signals into optical signals for transmission. Therefore, stacked lines are not optical modules. Which cables to choose depends on the stacking types of the switches, how far your switches are, your budget and other elements. A list of supported SFP adapters is available in the CBS datasheets.
