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/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
TC3005 is available in multiple configurations depending on your communication requirements. When both
sides have the same wavelength, the TC3005 works like an optical signal repeater.

A. The TC3005 consumes very low power. The connector is a terminal block with polarity indicated on the
rear panel of the unit (see Figure 2). The input voltage is typically 12 VDC and current is @600mA. The
unit can be ordered with optional power options: 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
feature will be utilized. When this feature is utilized, both "A" and "B" share the load. If one power source
fails, the other will assume the full load.

redundancy is utilized, both LEDs will be lit.
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-
MM RX: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-
SM Rx: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.

Note: Keep the "DISALM" dip switch in the Off or "up position" under normal condition.
A terminal block connector on the rear panel (labeled
"ALARM") provides for the dry contact relay alarm (see Figure
2). Normally in the OPEN position, the loss of either 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.

TroubleshootingTroubleshooting
Typically, most problems encountered with the TC3005 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 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.
The TC3005 has been adjusted at the factory so that the Single Mode transmitter will not overdrive the 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:

The following diagram illustrates a TC3005 Mode Converter used to convert a 1300nm Single Mode optical
signal from an OC3 (155 Mbps) ATM SWITCH into a 1300nm Multimode optic signal to be received by the
HP7000.* In the reverse direction, the HP7000's Multimode optic signal is converted to Single Mode format
to be received by the OC3 ATM SWITCH. In-line attenuators are used to correct optic overdrive conditions
that exist on either side of the TC3005.
