10/100BASE-TX to 100BASE-FX Bridge Media Converters
PLANET FT-80x is a Fast Ethernet Bridge 100BASE-FX fiber to 10/100BASE-TX
shielded twisted pair (STP) converter. It supports both half-duplex and full-duplex
operations and a variety of ber options. The converter auto-adapts to the highest level
of performance supported by the device connected to the STP port. When the device
is a switch or a workstation that supports full duplex, the converter adapts to the full-
duplex mode and provides an effective 200Mbps bandwidth. When the connected device
is a hub or a workstation that supports only half duplex, the converter adapts to the
half-duplex mode and provides the nominal 100Mbps bandwidth. An override switch
provides total manual control over the half/full-duplex operation in fiber-optic interface.
The fiber port of the converter operates at 1310 nm and uses ST, SC, MTRJ, VF45 or
WDM connectors. Multi-mode models that support distances up to 2km and single-mode
models that support distances up to 15/20/35/50/60km are available.
The FT-80x series is with LFP (Link Fault Pass-through function) (LLCF/LLR) and the
DIP switch design. LLCF/LLR can immediately alarm administrators the problem of the
link media and provide efficient solution to monitoring the net. The DIP switch provides
the disabling or enabling of the LFP function.
LLCF (Link Loss Carry Forward) means when a device is connected to the converter
and the TP line loses the link, the converter's fiber will disconnect the link of transmit.
LLR (Link Loss Return) means when a device is connected to the converter and the
fiber line loses the link, the converter's fiber will disconnect the transmit link. Both can
immediately alarm administrators the problem of the link media and provide efficient
solution to monitoring the net.
