4. Power Requirements
The TC3020R/S consumes very low power. The connector is a terminal block with polarity indicated on the rear panel of the unit. The input voltage is 12VDC and current is typically @200mA. Should an external power adapter need to be replaced, use one that matches these specifications. You may order it from TC Communications.

8. Troubleshooting
Typically, most problems encountered with the TC3020R/S 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 TC3020R/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 TC3020R/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 TC3020R/S 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.

The following diagram illustrates a TC3020R/S Mode Converter used to convert a 1300nm Single Mode optical signal from a customer’s device (5 Mbps) into a 1300nm Multimode optic signal to be received by a remote device. In the reverse direction, the remote device's Multimode optic signal is converted to Single Mode format to be received by the local device. In-line attenuators are used to correct optic overdrive conditions that exist on either side of the TC3020R/S.
Note: Launch power measurements may vary due to the actual optic signal's duty cycle variation.

9. Further Troubleshooting & Assessment Tests on your TC3020 Unit(s).
If you are having trouble establishing communication with your equipment and the TC3020 unit(s), you can test the unit(s) by performing the following simple assessment tests. If your application requires the use of one or two TC3020 unit(s), then the following procedures will apply to your system. You will need to perform a Single Mode Loopback test and a Multimode Loopback test on your TC3020 unit(s). These tests should be done using your PC’s hyperterminal.
Note: Make sure that your equipment’s wavelengths match with that of the TC3020’s. The 1310nm wavelength is shown as a reference only on the following figures.

Performing the Single Mode Loopback Test using one (1) TC3020.
The purpose of this test is to verify that the optical Singlemode TX/RX connectors are receiving and trans­mitting the incoming signal coming from the PC back to the PC. This test will ensure that the TC3020 unit(s) are working properly.
A. Testing your TC3020 for performance will require the testing setup shown on Fig. 5. Follow the connections shown on this figure and connect your equipment accordingly. You must also locate the DIP switches on the front panel of the TC3020 and enable the (SM LB) switch (switch #2) to the “ON” position as shown on Fig. 5.1.
1. Use an RS-232 adapter and connect it from your PC to a Single mode TC1200 fiber modem or a compatible RS-232 fiber modem.
2. After completing all of the connections you should be able to transmit and receive data.
3. You should observe that the (SM RX), (SM TX), and the (SM LB) LEDs are lit solidly ,therefore, indicating that the Single mode TX/RX receptacles on your TC3020 are working properly.
4. After you finish this test, reset switch #2 (SM LB) to the “OFF” position to perform the next test.
Figure 5. Single Mode loopback test on TC3020.
If your application requires the use of two TC3020’s to TX/RX your data, then the following tests will verify that your TC3020’s are working properly.
Performing the Single Mode Loopback Test on Unit B using two (2) TC3020 units.
The purpose of this test is to verify that the optical Single mode TX/RX connectors on Unit B are receiving and transmitting the incoming signal coming from the PC back to the PC. This test will ensure that the TC3020 unit(s) are working properly.
B. Testing your TC3020’s for performance will require the testing setup shown on Fig. 6. Follow the connections shown on this figure and connect your equipment accordingly. You will need to locate the DIP switches on the front panel of Unit B and enable switch #2 (SM LB) to the “ON” position as shown on figure 6.1.
1. Use an RS-232 adapter and connect it from your PC to a Multimode TC1200 fiber modem or a compatible RS­ 232 fiber modem.
2. After completing all of the connections you should be able to transmit and receive data.
3. You should observe that the (MM TX), (MM RX), (SM TX), and (SM RX) LEDs on Unit A are lit solidly. You should also observe that the (SM RX), (SM TX), and the (SM LB) LEDs are lit solidly on Unit B. This indi cates that both of the units are working properly.
4. After you finish this test, reset switch #2 (SM LB) on Unit B to the “OFF” position to perform the next test.

The purpose of this test is to verify that the optical Multimode TX/RX connectors are receiving and transmitting the incoming signal coming from the PC back to the PC. This test will ensure that the TC3020 unit(s) are working properly.
C. This test will require the testing setup shown on Fig. 7. Follow the connections shown on the figure below and connect your equipment accordingly. You must also locate the DIP switches on the front panel of the TC3020 and enable the (MM LB) switch (switch #1) to the” ON” position as shown on Fig. 7.1.
1. Use an RS-232 adapter and connect it from your PC to a Multimode TC1200 RS-232 fiber modem or a compatible RS-232 fiber modem.
2. After completing all of the connections, you should be able to transmit and receive data.
3. You should observe that the (MM TX), (MM RX), and the (MM LB) LEDs are lit solidly. This indicates that the TC3020 unit is working properly.
3. After you finish this test, reset switch #1 (MM SB) to the “OFF” position to perform the next test.
