3. Description
Featuring an “Industrial-Hardened” version for extreme environments, the TC3301 Gigabit Ethernet Fiber
Optic Converter supports distances up to 100km and is available with a 2-way single fiber option.
The TC3301 is IEEE802.3z/AB complaint. It converts or connects 1000Base-TX unshielded twisted-pair
devices (e.g. network bridges, switches, or workstation cards) to single mode (1300/1550nm) or multimode
(850nm) fiber optics.
Completely transparent to the network, the TC3301R/S is ideal for integrating UTP and fiber optics in any
Gigabit Ethernet network. It is designed with modern Field Programmable Gate Array (FPGA) technology
and operates efficiently even during high-demand traffic loads.
It is available in two temperature versions: 0°C to 50°C; -20°C to 70°C; The Industrial-Hardened version
exceeds all pertinent Utility and Traffic Control environmental and temperature specifications.
Diagnostics include 8 LEDs for Ethernet settings and Ethernet/Power status. Dry contact alarms are
provided for connection to remote network management systems. It is available standalone or rack mount.
The TC3301S is the standalone/wallmount unit. The TC3301R rackmount version fits into the Model
TCRM192 or 19" rackmount card cages.
Fiber optic connectors are ST, SC and FC. The UTP connector is RJ-45 female. Power is 12VDC @ 600mA
(standard); optional power sources include 24VDC, -48VDC, 125VDC, or 115/230VAC with an external
power cube.

These are the reference values we use to calculate the loss on the fiber:
Multimode 850nm :3 dB loss per km on 62.5/125µm cable*
Multimode 1310nm :2 dB loss per km on 62.5/125µm cable*
Single Mode 1310nm :0.5 dB loss per km on 9/125µm cable*
Single Mode 1550nm :0.25 dB loss per km on 9/125µm cable*
5. Optic Cable Types
Conventionally, fiber optic cable withyellow-coloredinsulation is used for Single Mode applications;gray
or orange-coloredinsulated cable is for Multimode use. If Multimode cable is used in a Single Mode
application, the test results could be erroneous and confusing.
6. Calculating the Loss on the Fiber
The fiber optic link and/or connectors are frequently the source of various problems. Check out the
connectors and the integrity of the link first. Ideally, the link should be calibrated for total loss after the
installation has been completed. This will accomplish two things: (1) it will verify that the total loss of the link
is within the loss budget of the device and (2) it will provide a benchmark for future testing. For example,
a system that has been tested as having 6dB total loss when installed and suddenly tests out as having a loss
of 10dB probably has a connector or link problem.
*These numbers are listed for reference only. We recommend an OTDR reading be used to determine actual link loss.

8. Power Requirements
A. Standard input power to the TC3301's is 12VDC @600mA.
B. The TC3301's power connectors are two terminal blocks located on the rear panel of the unit. Polarity
is indicated under each connector block (see Figure 2).
C. Should an external power adapter need to be replaced, use one with the following specifications: 12VDC
@600mA. You may order it directly from TC Communications.
D. The TC3301 can also be ordered with an optional 24VDC, 48VDC, 125VDC or 115/230VAC with an
external power cube.

This LED should light whenever power
is connected to the unit. It indicates the
correct operating voltage is being derived
from the power source.

Solidly lit, when Ethernet signal
is in 1000M full duplex mode.
Link LED indicator:
Solidly lit, when the twisted pair port has
established a valid link.

Fiber Optic Link Status LED:
Lit while receiving an optical
signal at the optical receiver (Rx).

both Power A and Power B share the load. If either
power source fails, the other one takes over full load.

Activity LED indicator:
Lit when there is Ethernet activity
detected through the RJ-45 port.
Note: As the Ethernet activity going through
the RJ-45 port becomes greater, this LED
will become brighter.
1000M LED indicator:
This LED will always be lit
since the media converter
operates at a fixed 1000Mbps.

9. Installation
A. Connect the standard 12VDC power supply to the TC3301 (24VDC, 48 VDC, 125VDC or 115/230VAC
with an external power cube are optional).
B. The "PWRA," and/or "PWRB," "1000M," "Vcc," LEDs should be lit.
C. Use CAT 5E or 6 UTP cable to connect the TC3301 RJ-45 port to the 1000Base-T Port of your network
device. The "FDX," and "LNK," LEDs will be lit. If the LEDs are "Off," please verify the cable
connection and the power of the network device.
D. Connect the optic cables according to the example diagrams shown on page 7. For example, on diagram
C;the localTC3301's optic"Tx" shouldbe connectedto theremote networkdevice's optic"Rx" andvice-
versa.
E. After step "D," the "FO" LED should light to indicate that the optical idle signal is being received.
F. Create some activity on the Ethernet, the "ACT" LED should be lit.
Note: As the Ethernet activity going through the RJ-45 port becomes greater, this LED will become brighter.
G. Double-check all LEDs according to the following:
The "PWRA," and/or "PWRB," "Vcc," "FO," "1000M," "FDX," "LNK," and "ACT" LEDs should be lit.
The "FO" LED will be lit when the optic side has activity and/or fiber optic cables are connected.
The "ACT" LED will be lit when the UTP side has activity.

10. Dry Contact Relay Alarm
Aterminal blockconnector on therear panel(labeled "ALARM")
provides for the dry contact relay alarm (see Figure 2). Normally
in the OPEN position, any loss of optical signal will trigger an
alarm condition and force the switch to the CLOSED position.
This relay can be used in conjunction with an external device to
monitor the condition of the fiber optic links.

14.Troubleshooting
After installation is complete, only the "PWRA," and/or "PWRB," "Vcc," "LNK," "FO," "1000M," and "FDX"
LEDs should be lit. If not, please check the following:
Power Problem:
No LEDs are lit:
A. "PWRA" and/or "PWRB" LEDs should be on when power is connected. If both are "Off," then no DC
power is reaching the unit. Check the power supply, source, and polarity.
B. If "PWRA," and/or "PWRB," "Vcc," or "1000M" LEDs are "On" but all other LEDs are "Off", and the
Alarm switch is not closed, it indicates an internal problem with the unit. For assistance, please contact
the Technical Support Department at TC Communications @ [phone].
Electrical Problem:
If the LNK or FDX LEDs are Off:
It means that there is no Ethernet electrical signal detected by the TC3301. Check the electrical
connections on the Cat 5E or 6 cable. Make sure that there's Ethernet signal being provided and that the
signal is 1000M. Also, check that the Ethernet cable is good.
Optical Problem:
The "FO" LED should be lit at all times to indicate good optic transmit and receive conditions and good cable
connections.
If the FO LED is OFF:
A. Optic power received by "Rx" is lower than the typical sensitivity.
B. Optic "Tx" is connected to another TC3301's "Tx." Check the optic cable connection; the local unit's optic
"Tx" should be connected to the remote unit's optic "Rx."
C. Optic cable type is incorrect. Typically, fiber optic cable with yellow-colored insulation is designated for
Single Mode use @8.2µm or 9µm; orange or gray-colored cable is for Multimode use @50µm or 62µm.
If the wrong cable type is used, the unit will not function properly.

A. Copper to Copper over Fiber:
Make sure you connect the local TC3301's "Tx" to the remote TC3301's "Rx" and vice-versa.
C. Copper to Fiber:
Connect the optical cables according to the diagram below, the local TC3301's optic "Tx" should be connected
