If, for example, a fault occurs
on a converted fiber segment, FX
LinkLoss™ detects the fault and
passes this information to the
twisted-pair segment. It then
disables the twisted-pair port’s
transmitter, resulting in a loss of link
on the device connected to that
port. TX LinkLoss performs a similar
function, detecting faults on
twisted-pair segments and passing
this along to the fiber port.
With autonegotiation enabled,
the converter negotiates as a
100-Mbps full-duplex device and,
if the connected device can
operate at that speed and duplex,
it establishes a link.
To activate FX LinkLoss and
autonegotiation functions, simply
flip a switch on the faceplate of the
converter. Internal jumpers control
TX LinkLoss.
For diagnostic and monitoring
purposes, each Single-Strand Fiber
Media Converter has four LEDs:
• FX RCV turns yellow when
the fiber port receives data.
• TX LNK turns green when
the converter establishes a
twisted-pair link.
• FX LL turns green when you
enable FX LinkLoss.
• FX LNK turns green when
the converter establishes a
fiber link.
Compact yet durable, the
converter‘s design benefits from a
metal casing and four preinstalled
rubber feet for placing the unit on
a desktop. And because its
autosensing, universal power
supply is internal, there’s no bulky
transformer to crowd your work
space further.
Plus, you won’t need any
crossover cables to complicate
connections at the 100BASE-TX
port. You can get away with using
straight-through cabling only
to connect your copper devices.
That’s because the converter has
an MDI/MDIX function that
automatically determines whether
the converter has to cross over
between the four pairs on the
RJ-45 connector. Depending on the
connected device, a Single-Strand
Fiber Optic Converter selects
between a crossover workstation
or passthrough repeater or hub
connection.
