Insert a compatible SFP transceiver into the converter's port, making sure it matches the network's media type and speed. Then, connect one end of the fiber cable to the transceiver and the other to the appropriate port on a switch, router, or another media converter. SFP (Small Form-factor Pluggable) is a compact, hot-pluggable network interface module used to connect network devices (switches, routers, firewalls) to fiber optic or copper cables. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper. FO media converters for Ethernet and fieldbus enable you to convert your copper interfaces to interference-free fiber optics without the need for complex surge protection, shielding, and equipotential bonding measures. By converting electrical signals into optical signals—and vice versa—SFP. Improve safety, signal integrity, and reliability by using two optical fibers instead of wire to transfer bidirectional serial data using single-mode optical fiber. Apply for instrumentation, protection, automation and other applications that benefit from economical fiber-optic links up to 23. WDM transponder is also known as optical to electrical to optical (OEO). The WDM systems see wide adoption of WDM transponder (OEO) for converting legacy wavelength to CWDM or DWDM wavelength.
