The Fast Ethernet media converters series are designed to bridge a 10/100BASE-T signal to a 100BASE-FX signal. It's used to extend the connection distance between two Fast Ethernet Twisted-pair devices via fiber cable transparently with no performance degradation.
The converter series is based on switching hub design. It's supported Autonegotiation & flow control function on Twisted-pair port. And provided different types of fiber connectors such as SC and ST for multi-mode or single-mode cables.
