MCC-DFL SETUP

4.1 OVERVIEW OF THE MCC-DFL

The MCC-DFL has two independent Fiber Optic Transceivers (FOTs).
Each FOT has an RJ45 and fiber ST port; thus allowing signals
transmitted over the twisted pair to be converted to optical signals for
transmission over multimode fiber and vice versa. The top RJ45 and
fiber ST port (FOT-A) and the bottom RJ45 and fiber ST port (FOT-B) are
on separate rings and do not communicate with each other within the
MCC-16. Communication between FOT-A and FOT-B requires an
external device such as a bridge or router. You can configure any port as
RI, RO, lobe, or station.
configured for station/lobe applications and FOT-B configured for RI/RO
applications.
