While fiber optic (SFP) ports are becoming increasingly common on networking electronics, the majority of devices still rely on a twisted pair (RJ45) connection. Media converters are often used to bridge the connection divide and expand device functionality.
For example, media converters integrate twisted pair electronics with fiber optic cable to extend transmission distance and create immunity from surges, static, lightning and signal interference. They can be used in pairs, with one media converter on each end of the cable run, or in conjunction with other network-based devices, such as a fiber-enabled network switch.

Media converters typically require an SFP transceiver module to complete the fiber optic connection. These modules are specific to the type of fiber being connected (either single mode or multimode). Choose an SFP module based on the fiber optic cabling that will be connected to the network switches.
SFP transceiver modules almost always require two fiber optic cable strands. Always integrate duplex (two strand) fiber optic cabling or higher strand counts.
Most modern SFP transceiver modules feature duplex LC connections. Terminate your fiber optic cabling with two LC-style connectors or purchase a pre-terminated fiber optic cable with two LC-style connectors.
When connecting terminated duplex fiber optic cable between media converters and/or network equipment, ensure the connections are reversed between the SFP transceiver ports (connection A to B and B to A). SFP transceiver modules rely on the transmission of separate send and receive signals.
Select an SFP module that matches the bandwidth of your media converter and/or network equipment. 1G modules are technically classified as SFP transceivers, 10G modules are classified as SFP+ transceivers, and QSFP transceivers support even higher bandwidths.
When integrating two media converters or one media converter with one fiber-enabled network device, it is important to verify both devices feature matching SFP modules to ensure compatibility and proper communication.
Media converters convert a twisted pair connection to a fiber optic connection, effectively adapting a device with an RJ45 port to a fiber-ready device. TechLogix media converters require an SFP module. View
