This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated
in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and
used in accordance with the Instruction manual, may cause
harmful interference to radio communications. Operation of
this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct
the interference at whose own expense.

Chapter 1 OVERVIEW
Thank you for choosing the Smart 10/100Base-TX to 100BaseFX 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 10/100BaseTX 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
network. The SFP slot supports single-mode, multi-mode and
WDM small-form factory type transceiver modules for your
needs. With 100Base-FX SFP ports, the FT-1105A and FT-1205A
are with high reliability and exibility to extend the distance up
to 2Km, 20Km, or longer. It depends on the 100Base-FX SFP
transceiver modules.
Ethernet signal that allows two type segments connect easily,
efciently and inexpensively.
The converters can be used as a stand-alone unit or as a slidein module to the PLANET Media Converter Chassis (MC-700, MC-1000R and MC-1500). As the other PLAENT FT-Series
media converters, they’re hot swappable in MC-Chassis.

Redundancy
● Link status auto detect and redundant on Dual ports with
same connector type.
● Only Primary-Port is active at a time, the Backup-Port is
blocked.
● While Primary-Port link fail occur, the trafc swap to Backup-
Port automatically.
● Once the Primary-Port status back to link up, the trafc swap
from Backup-Port to Primary-Port.
● Hardware redundant swap less than 10 ms.
Mechanical
● External 5V/2A DC power supply
● LED indicators for easy network diagnose
