Introduction
Transition Networks SBFTF10xx-10x 2-port Ethernet/Fast Ethernet bridging media converter connects
10Base-T Ethernet or 100Base-TX Fast Ethernet twisted-pair copper network devices to network devices
on a 100Base-FX Fast Ethernet fiber network.
The SBFTF10xx-105 provides an interface between 10/100Base-TX ports and 100Base-FX ports, allowing
users to integrate fiber optic cabling into 10/100Base-TX copper environments. Operating at Layer 2,
this converter not only converts copper to fiber, but it also does Rate Conversion, converting 10/100
copper to 100Base fiber.
