Planet FT-1205A [6/24] Chapter 1 overview

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 congured

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
