Can I use hub instead of switch to connect with fiber converter?
Yes, fiber converter can be used with hub or switch. But for optimal performance, to fully utilize the fibers long-range transmission advantage, the 100Base-TX/FX converters should be deployed together with switches and not hubs. Switches support full duplex mode while hub not. This allows point-to-point connection of up to 2Km for multi-mode fiber and up to 100Km for single mode fiber.
