Introduction 

Transition Networks CBFTF10xx-10x two-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 CBFTF10xx-10x provides an interface between 10/100Base-TX ports and 100Base-FX ports, allowing 

you 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.
