OVERVIEW
Thank you for choosing the Smart 10/100Base-TX to 100Base-FX
Media Converter, The Media Converter introduced here provides
one channel media conversion between 10/100Base-TX and
100Base-FX.
About the Redundant Media Converter
The FT-1105A and FT-1205A are 3-Port Redundant Media
Converters which support conversion between 10/100Base-TX and
100Base-FX network. Different with the other one-port channel
media converter, the Redundant Media Converters are designed
for critical networks that require fiber or copper link auto recover
less then 10ms, such as ISP, telecom, hospital, banking and
enterprise. The two models of PLANET Redundant Media converter
as following:
 FT-1105A: 100Base-FX to two 10/100Base-TX copper
link redundancy
 FT-1205A: 10/100Base-TX copper to two 100Base-FX
fiber link redundancy
Via the build-in DIP-switches, the two models can be configured
as 3-Port Ethernet switch or 2-Port Redundant media converter.
With the 3-Port Switch mode, they work in high performance
Store and Forward mechanism, also can prevent packet loss with
IEEE 802.3x Flow Control (Full-Duplex) and Back Pressure (Half-
Duplex).
With 2-Port redundant Mode, it provides less than 10ms link
redundancy for highly critical Ethernet applications. The redundant-
mode supports auto-recover function. If the destination port of a
packet is link down, it forwards the packet to the other port of
the backup pair.
