Chapter 1 - Overview
Description
The TC3007 gives users the ability to convert Multimode (or Single Mode) fiber optic signals to Single Mode
format for data transmission over a "One Fiber" optic cable. These conversions can benefit users by
extending transmission distances and/or enabling dissimilar fiber optic devices to be used with different fiber
types. The built-in Wave Division Multiplexer (WDM) enables the combination of 1310nm & 1550nm
wavelengths into one fiber for full duplex communication over a single (One) fiber. The optic receiver on the
left side detects the incoming optical signal and regenerates it for transmission through the optic transceiver.
At the receiving end, the TC3007 separates the optic signal, converts it, and retransmits it to the remote
device via its optic transmitter. The unit is available in multiple configurations depending on your
communication requirements; when both sides have the same wavelength, the TC3007 works like an optical
signalrepeater. Typically,the unit consistsofone setof MultimodeLED/ELED optics(on theleft-hand side
of the unit) and one Single Mode LASER transceiver optic (on the right-hand side of the unit).

Chapter 2 - Installation
Unpacking the Unit
Before unpacking any equipment, inspect all shipping containers for evidence of external damage caused
during transportation. The equipment should also be inspected for damage after it is removed from the
container(s).Claims concerningshipping damageshouldbe madedirectlyto thepertinentshipping agencies.
Any discrepancies should be reported immediately to the Customer Service Department at TC Communi-
cations, Inc.
Equipment Location
The TC3007 should be located in an area that provides adequate light, work space, and ventilation. Avoid
locating it next to any equipment that may produce electrical interference or strong magnetic fields, such as
elevator shafts or heavy duty power supplies. As with any electronic equipment, keep the unit from excessive
moisture, heat, vibration, and freezing temperatures.
Power Supply
Standard input power to the TC3007 is 12VDC @600mA. There are two pairs of terminal block connectors
on the rear panel (labeled "PWR A" and "PWR B"). Only one pair is required to power the unit. Polarity
is indicated on each connector block. If both pairs are connected, the built-in power redundancy feature will
beutilized. When this feature is utilized, both "A" and "B" share the load. If one power sourcefails, theother
willassume thefullload. Polarity isindicated on eachconnector block.Alternatepower sourcesareavailable
as an option (see Chapter 4 - Specifications).
Dry Contact Relay Alarm
A terminal block connector on the rear panel (labeled
"ALARM") provides for the dry contact relay alarm (see Figure
2). Normallyin theOPEN position, theloss ofeither optic 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. Note: If SW4 (DISALM) on the front panel is in the
Down position, the audio buzzer will not sound and the dry
contact relay will not activate.

Chapter 3 - Troubleshooting
Typically, most problems encountered with the TC3007 are related to optic receiver overdrive. The
maximum optic power that can be received without distortion is referred to as the optic receiver's "saturation
level." When the incoming optic power is greater than the saturation level of the receiver, optic "overdrive"
can occur.
The TC3007's optic receivers have a typical saturation level of -14 dBm. If the user's equipment's launch
power is higher than -14dBm (i.e. -13dBm or greater) and the fiber run is very short and has low signal loss,
it is likely to overdrive the TC3007's Multimode receiver. The consequences of overdrive can be high error
rates or the device's failure to recognize the incoming optic signal at all.
TheTC3007has been adjustedatthefactory so thattheSingleMode transmitter willnotoverdrivethe Single
Mode receiver even when short cables are used to connect them; hence, the overdrive condition happens
most frequently at the Multimode receiver optic.
If you suspect the Multimode receiver has an optic overdrive condition, a simple test will help verify it. At
the receiving optic in question, simply disconnect the optic connector and back it out of the receptacle (about
1/8 of an inch), creating a gap between the fiber connector and the receiver. Verify that the equipment is
still in "sync" with the optic signal and that the overdrive condition has been corrected. To resolve the
overdrive condition permanently, insert a 5dB or 10dB in-line attenuator into the problem link. In-line
attenuators can be purchased from Metrotek* at (727) 547-8307. The part numbers are:

Part Number: 68-JJ-7-0513 68-JJ-7-1013
The following diagram illustrates a TC3007 Mode Converter used to convert a 1300nm Multimode optical
signal from a Multimode 1310nm Transceiver (155 Mbps) into a 1550nm Single Mode optic signal to be
received by a second TC3007 with a 1550nm receiver optic. In the reverse direction, the Single Mode optic
signal is converted to Multimode format to be received by Transceiver (user's device). In-line attenuators
are used to correct optic overdrive conditions that may exist on Multimode side of the TC3007.

Note: Launch power measurements are taken at 155Mbps and may vary due to the actual signal's duty cycle.
