The LANart rack-mountable FXC1x15T series multi-port media converters,
FXC1115T and FXC1215T, allow the network administrator of a large and
complex network to extend the distances between multiple 100BASE-TX
devices and multiple 100BASE-FX devices.
FXC1115T
Provides six (6) independent media converter connections between 100BASETX signals over twisted pair copper (RJ-45 connectors) and 100BASE-FX
signals over fiber-optic cable (RX receive and TX transmit ST connectors).
FXC1215T
Provides twelve (12) independent media converter connections between
100BASE-TX signals over twisted pair copper (RJ-45 connectors) and 100BASEFX signals over fiber-optic cable (RX receive and TX transmit ST connectors).
NOTE: The multi-port media converter AutoCross™ feature allows either
straight-through or crossover twisted-pair copper cable to be used when
connecting to 100BASE-TX devices. AutoCross™ determines the
characteristics of cable connections to the media converter port and then
automatically configures the port to
link up.

FXC1X15T IN THE NETWORK
Each media converter port in the FXC1x15T multi-port media converter
operates independently over one isolated twisted-pair copper/fiber-optic
cable link. The media converter port receives and transmits network
signals in either full-duplex or half-duplex, depending upon the network
devices to which the media converter port is attached, and is designed
to work effectively with 10/100 autonegotiating ports to provide reliable
100 Mbps fiber links.

CABLE SPECIFICATIONS
The physical characteristics of the media cable must meet or exceed IEEE 802.3
specifications.
FIBER CABLE
MULTIMODE
Fiber Optic Cable Recommended: 62.5 / 125 µm multimode fiber
Optional: 100 / 140 µm multimode fiber
85 / 125 µm multimode fiber
50 / 125 µm multimode fiber
Wavelength : 1300 nM
Attenuation: 1.5 dB/ 1 kilometer @ 1300 nM
Maximum Number of Nodes: 2 nodes
Maximum Cable Distance: Half-duplex: See page 3
Full-duplex: 2 kilometers (6562 feet)
Media Standards: IEC 793-2, Type A1b, category 3.5 dB/km
COPPER CABLE AND CONNECTOR
Category 5 twisted-pair copper wire is required. Either shielded twistedpair (STP) or unshielded twisted-pair (UTP) can be used. DO NOT USE
FLAT OR SILVER SATIN WIRE.
CATEGORY 5:
Gauge 24 to 22 AWG
Attenuation 22.0 dB /100m @ 100 MHz
Maximum Number of Nodes: 2 nodes
Maximum Cable Distance: 100 meters
RJ-45 Pin-out:: Pin 1=TD+, Pin 2=TD-,
Pin 3=RD+, Pin 6=RD-
Twisted pair connection requires two active pairs configured as straight
through and/or crossover. The two active pairs in an Ethernet™ network
are pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as
blue/white & white/blue, orange/white & white/orange) for the active pins.
Media Converter Port in Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the
cables used. See page 10 for cable specifications.
NOTE: The 512-Bit Rule described below does NOT apply in a full-duplex
network.
Media Converter Port in Half-Duplex Network
The 512-Bit Rule applies separately to each collision domain.
USING THE 512-BIT RULE
In a half-duplex network, maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet
™ collision domain.
(Switches and routers divide the network into separate Ethernet™ collision
domains.) The 512-Bit Rule determines maximum distances by calculating
the collision domain round-trip delay in bit-times.
To calculate a collision domain round-trip delay in bit-times, find the longest
path between any two terminal devices in the collision domain. Calculate the
round trip delay by multiplying the
length of the cable (in meters) by the
delay per meter (in bit-times (BT)),
then take the sum of all cable delays
plus station (DTE), repeater, and
multi-port media converter port
delays. If the result is less than or
equal to 512 bit-times, the path is
good.

FAULT ISOLATION and CORRECTION
If the media converter fails, isolate and correct the fault by determining the
answers to the following questions and then taking the indicated action:
1. Is the P(o)W(e)RLED on the media converter illuminated?
NO
• Is the power cord properly installed in the media converter and in
the grounded AC outlet?
• Does the grounded AC outlet provide power?
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
• Proceed to step 2.
2. Does one of the green 100BASE-TX Status LEDs blink once* and
go off?
YES
• Check twisted pair cables for proper connection.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NO
• Proceed to step 3.
3. Does one of the green 100BASE-FX Status LEDs blink once and
go off?
YES
• Check fiber cables for proper connection.
• Verify that TX and RX cables on media converter are connected to
RX and TX ports, respectively, on other device.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NO
• Proceed to step 4.
4. Does one of the green 100BASE-FX Status LEDs blink twice and
go off?
YES
• Determine cause of Far End Fault and then repair or replace faulty
cable or equipment in copper link.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NO
• Proceed to step 5.
*If one of the 100BASE-TX Status LEDs blinks twice, the 100BASE-TX
link is Auto-Negotiating. If the media converter port is connected to a
100BASE-TX device, no action is necessary. If the media converter port
is connected to a 10BASE-T device, the multi-port media converter will
not operate properly.
Install Cable
COPPER
NOTE: KEEP TWISTED PAIR RUNS AS SHORT AS POSSIBLE.
NOTE: AutoCross™ allows the use of either straight-through or crossover
configuration cables.
1. Locate or build 100BASE-TX compliant cables with male RJ-45
plug connectors at both ends.
2. Connect male RJ-45 plug connector at one end of cable to media
converter port RJ-45 jack connector.
3. Connect male RJ-45 plug connector at other end of cable to
100BASE-TX device RJ-45 jack connector.
FIBER
1. Locate or build 100BASE-FX compliant fiber cable with male two-
stranded TX to RX connectors at both ends.
2. Connect male TX and RX cable connectors at one end of cable to
TX and RX female connectors, respectively, on media converter
port.
3. Connect male TX and RX cable connectors at other end of cable to
RX and TX connectors, respectively, on 802.3 compliant fiber
device.
Connect to Power
1. At multi-port media converter back, locate male power receptacle.
2. Plug female media converter end of power cord into multi-port
media converter power receptacle.
3. Plug male outlet end of power cord into correct voltage, properly
grounded, AC rack or wall power source.
4. Verify that multi-port media converter is powered by observing
illuminated power and status LED(s).
OPERA TION
Use the status LEDs to monitor multi-port media converter operation in the
network.
NOTE: Each 100BASE-TX/ 100BASE-FX port, when facing the multi-port
media converter, is numbered consecutively at the left of the 100BASE-TX
connector for that port. The LEDs that apply to each 100BASE-TX or
100BASE-FX connection in the port are located, when facing the multi-port
media converter, at the right of the connector(s) for that 100BASE-TX or
100BASE-FX port connection.
Green LED = Status Yellow LED = Activity
STATUS (100BASE-TX) Steady green LED indicates normal
operation.
One (1) continuous, flashing blink indicates
Link Down.
Two (2) continuous, flashing blinks indicates
100BASE-TX link is Auto-Negotiating.
ACTIVITY (100BASE-TX) Flashing yellow LED indicates 100BASE-TX
activity.
STATUS (100BASE-FX) Steady green LED indicates normal
operation.
One (1) continuous, flashing blink indicates
Link Down.
Two (2) continuous, flashing blinks indicates
reception of Far End Fault on 100BASE-TX
link.
ACTIVITY (100BASE-FX) Flashing yellow LED indicates
100BASE-FX
activity.
POWER Steady green LED indicates power.
Using LinkAlert™
The FXC1x15T series multi-port media converter LinkAlert™ feature allows
each media converter port to pass 100BASE-TX-side link faults over the port link
to the 100BASE-FX side and to pass 100BASE-FX-side link faults over the port
link to the 100BASE-TX side.
If the port does not detect a good link on the 100BASE-TX side, the port disables
all transmission (including active-idle) on the 100BASE-FX side AND the green
100BASE-FX STATUS LED on the multi-port media converter blinks twice.
* The 100BASE-FX STATUS LED
continuously blinks twice until the far end
100BASE-TX fault is corrected.
NOTE: No similar LED display exists for faults on the 100BASE-FX link, but if
the port does not detect a good link on the 100BASE-FX side, the port DOES
disable all transmission (including link-integrity) on the 100BASE-TX side until
the far end 100BASE-FX fault is corrected.
