Solution: Using the intermediate switch with SMF and MMF interfaces that is able to convert the signals is a good alternative. If you use simple devices, such as video over fiber, or media converters, then it depends, what wavelength are used for your equipment. To realize the short-range direct connection to the end B switch with the same port, the same 10GBASE-SR SFP+ module should be plugged into the end B switch port. This is the most ideal and simple application scenario. What if end B is located in. MMF is typically using LEDs for transmission of the optical signal. It receives the optical signal on one port, converts it into an electrical signal, and then retransmits it as an optical. A fiber optical switch is a network device designed to control the routing of optical signals between different fiber paths. Although they can do the same job in some instances, the different construction methods make each of them better suited to certain tasks and budgets.
