Direct attach cables with pre-terminated SFP connections may also be used. Download the Application. A practical B2B guide explaining what a fiber optic switch is, how to connect fiber optic cable to Ethernet switches, how to connect two switches with fiber, how to disconnect fiber safely, and how to select suitable fiber modules, patch cords, media converters and switch solutions. A practical B2B. I have just had a 1GB Leased Line installed and the interface (connectivity presentation) is MMF (Multi Mode Fibre) and terminates at an ADVA FSP 150-GE102Pro, so I purchased a managed switch by FS, model S3700-24T4F, as this had SFP sockets. Choose an SFP module based on the fiber optic cabling that will be connected to the network switches. Moreover, when it comes to bandwidth, no currently available technology is better than single-mode fiber. It can provide significantly higher bandwidth and carry more data.
