Fiber Optic Port
The AT-FS201, AT-FS202, and AT-FS202SC/FS1 Bridging Media
Converters have one 100Base-FX fiber optic port. The fiber optic port
features either a dual SC or a dual ST connector, depending on the
model.
Port Speed
The fiber optic port is compliant with the 100Base-FX standard and has a
fixed operating speed of 100 Mbps. The end-node connected to the fiber
optic port on the converter must also be able to operate at 100 Mbps.
Duplex Mode
The fiber optic port on the converter can operate in half- or full-duplex
mode. You must set the duplex mode manually using the DIP switches on
the back of the unit.
