Description
The TC3005 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/orenablingdissimilarfiberopticdevicestobeusedwithdifferentfibertypes. Theopticreceiverdetects
the incoming optical signal and regenerates it for transmission through the second optic transmitter. The
TC3005isavailableinmultipleconfigurationsdependingonyourcommunicationrequirements. Whenboth
sides have the same wavelength, the TC3005 works like an optical signal repeater.

A. TheTC3005consumesverylow power. The connector is a terminalblock with polarityindicated onthe
rearpaneloftheunit(seeFigure 2). The input voltage is typically 12VDC and current is@600mA. The
unitcanbeorderedwithoptionalpoweroptions: 24 VDC@300mA, 48 VDC@150mA, or 115/230 VAC
with an external power adapter.
B. Should an external power adapter need to be replaced, use one that matches the above specifications.
You may order it from TC Communications.
C. 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. If both pairs are connected, the built-in power redundancy
featurewill beutilized. Whenthisfeature isutilized,both"A" and"B"sharetheload. Ifonepowersource
fails, the other will assume the full load.

Alarm Buzzer & ALM LED Flashing - Indicates that the optical signal is not present or lost at the Multimode and/or
Dry contact Relay: Singlemodereceiver(s)andthealarmwillbetriggered.
ALM LED Off - Indicates the unit is under normal working condition (receiving good optical signals).
AlarmCondition:
When the Alarm is triggered, the alarm buzzer will sound & the dry contact relay will close. (see section 6 on next page).
Power Supply Status Indicators-
PWRA/B: When lit, these LEDs indicate which power source on the rear panel the unit is drawing from. If power

Vcc: +5V Voltage indicator. The Vcc LED should light solidly whenever power is connected to the unit.
It indicates the correct operating voltage is being derived from the power source.
Multimode Optic Signal Status Indicators-
MMRX: Solidly lit, indicates a valid optical signal is received at the MM receiver & it is above sensitivity threshold.
Off, indicates the optical signal at the MM RX is not present, lost, bursty or questionable (not valid).
- Verify that the user’s Multimode device optical wavelength matches that of the TC3005 units.
- Verify the integrity of the Multimode fiber cables and connections.
Single Mode Optic Signal Status Indicators-
SMRx: Solidly lit, indicates optical signal at the SM optic receiver is received & it is above sensitivity threshold.
Off, indicates the single mode optical signal at the SM optic receiver is not present or it is lost.

Troubleshooting
Typically, most problems encountered with the TC3005 are related to optic receiver overdrive. The
maximumopticpowerthatcanbereceivedwithoutdistortion 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 TC3005'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 TC3005'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.
TheTC3005has been adjusted at the factory so that the Single ModetransmitterwillnotoverdrivetheSingle
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
thereceivingopticinquestion,simplydisconnecttheopticconnectorandbackitout 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:
