Chapter 1 - Overview
Description
The TC3006 gives users the ability to convert Multimode fiber optic signals to Single Mode format for data
transmission (and vice-versa). These conversions can benefit users by extending transmission distances and/
or enabling dissimilar fiber optic devices to be used with different fiber types. The optic receiver detects the
incoming optical signal and regenerates it for transmission through the second optic transmitter. The TC3006
isavailableinmultiple configurationsdepending onyour communicationrequirements. When bothsides have
the same wavelength, the TC3006 works like an optical signal repeater.

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 concerningshippingdamage shouldbe madedirectly to thepertinentshipping agencies.
Any discrepancies should be reported immediately to the Customer Service Department at TC Communi-
cations, Inc.
Equipment Location
The TC3006 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 TC3006 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 theload. If onepower sourcefails, theother
willassume thefull load. Polarity isindicated oneachconnector block.Alternate power sourcesare available
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 opticsignal
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 TC3006 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.
Forexample,theTC3006's(SingleMode1310nm,20kmmodel) opticreceivershaveatypical saturation level
of -3dBm. If the user's equipment's launch power is higher than -3dBm (i.e. -2dBm or greater) and the fiber
run is very short and has low signal loss, it is likely to overdrive the TC3006'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.
TheTC3006has beenadjusted atthe factorysothatthe SingleMode transmitterwill notoverdrive theSingle
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 [phone]. The part numbers are:
Description: ST@5dB ST@10dB FC@5dB FC@10dB
Part Number: 68-JJ-7-0513 68-JJ-7-1013 68-FF-0513 68-FF-1013
The following diagram illustrates a TC3006 Mode Converter used to convert a 1310nm Single Mode optical
signal from a Gigabit Switch #1 into an 850nm Multimode optic signal to be received by a second Gigabit
Switch #2. In the reverse direction, the Gigabit Switch #2's Multimode optic signal is converted to Single
Mode format to be received by the Gigabit Switch #1. In-line attenuators are used to correct optic overdrive
conditions that exist on either side of the TC3006.
