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 fiber 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 fiber 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 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 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
