An SFP module is a small transceiver that plugs into a switch, router or OLT to connect it over fiber. This category includes 1G and 10G SFP / SFP+ transceivers and PON-port optics, in single-mode and multi-mode versions, from TP-Link, Ficer, BDCOM, Cisco, Cudy, VSOL and Xtreme. They are popular with network engineers and ISPs connecting switches, routers and OLTs over fiber.
An SFP port lets one device work with different fiber types and distances simply by changing the module, so choosing the right module matters as much as choosing the switch itself.
Q: Can I use an SFP module from another brand in my switch?
A: Many switches accept third-party modules, but some only accept brand-coded ones. Check your switch documentation or ask us with the model.
Q: What is the difference between single-mode and multi-mode SFP?
A: Single-mode is for long distances over single-mode fiber; multi-mode is for short distances over multi-mode fiber. They are not interchangeable.
Q: Do BiDi modules need to be bought in pairs?
A: Yes. A BiDi link uses two modules with opposite wavelengths, one at each end.
