Operation
LED indicators
Use the status LEDs to monitor the media converter operation in the network.
FX LED
on = The fiber link has been established.
TX LED
on = The copper link has been established.
Product features
Auto-Negotiation
The Auto-Negotiation feature allows the media converter to automatically configure
itself to achieve the best possible mode of operation over a link. This feature allows
quick and easy installation because the optimal link is established automatically.
No user intervention is required to determine the best mode of operation.
Link-Pass Through
The Link Pass-Through feature allows the media converter to monitor both the fiber
and copper RX
(receive)
ports for loss of signal. In the event of a loss of an RX
signal (1), the media converter will automatically disable the TX
(transmit)
signal
(2), thus, “passing through” the link loss (3). The far-end device is automatically
notified of the link loss (4), which prevents the loss of valuable data unknowingly
transmitted over an invalid link.

Operation

Pause control frame
The pause feature is used to temporarily suspend data transmission in order to
relieve buffer congestion. If a media converter needs some time to clear network
congestion, it will send a pause signal to the media converter at the other end, which
will wait a predetermined amount of time before re-transmitting the data. This
feature reduces data bottlenecks, allows for a more efficient use of the network
devices, and prevents the loss of valuable data.
Note:
Enable the pause feature if it is present on ALL network devices attached to
the media converter(s). Otherwise, disable the pause feature.
Note:
Disable the pause feature in networks with E-911, VoIP, or other time-
critical applications.
Far-end fault
When a fault occurs on an incoming fiber link (1), the media converter transmits a
Far-End Fault signal on the outgoing fiber link (2). In addition the Far-End Fault
signal also activates the Link Pass-Through feature, which, in turn, disables the link
on the copper portion of the network (3) and (4).

Cable Specifications
Copper cable
Wire:
Cat 5
Gauge:
24 to 22 AWG
Attenuation: 22.0 dB /100m @ 100 MHz
• Straight-through (MDI) twisted-pair cable must be used.
• Shielded (STP) or unshielded (UTP) twisted-pair cable may be used.
• Pins 1&2 and 3&6 are the two active pairs in an Ethernet network .
• RJ-45 Pin-out: Pin 1 = TD+, Pin 2 = TD-, Pin 3 = RD+, Pin 6 = RD-
• Use only dedicated wire pairs for the active pins:
(e.g., blue/white & white/blue, orange/white & white/orange, etc.)
• Do not use flat or silver satin wire.
