Chapter 1 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 ber or copper link
auto recover less than 10ms, such as ISP, telecom, hospital,
banking and enterprise. The two models of PLANET Redundant
Media converter as following:
●
FT-1105A: 10/100Base-TX copper to two 100Base-FX ber
link redundancy
●
FT-1205A: 100Base-FX to two 10/100Base-TX copper link
redundancy
Via the built-in DIP-switches, the two models can be congured
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 10ns
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.
The Redundant Media Converters - FT-1105A and FT-1205A,
support conversion between 10/100Base-TX and 100Base-FX
