1.1 Options 1.1 Options The 7870 Interfacility Link comes with a variety of options: 1. 50 Ω Input/Output Impedance/BNC female connector; Standard impedance is 75 Ω/BNC, female connectors. 2. Standalone unit; The 7870 IFL can be installed as a standalone unit. If the 7870 is used as a standalone, a separate power supply must be used. On the side of the 7870T and the 7870R units is a label1 which lists the options. Under each option is a square.

2 Installation Chapter 2 describes how to install the 7870 Interfacility Link units. Setting up the 7870E Transmitter/Receiver consists of: 2.1 2.2 2.3 2.4 2.4.1 2.5 2.6 Setting up the Transmitter. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Connecting the Fiber Optic Cable. . . . . . . . . . . . . . . . . . . . . . . . . . . 9 Setting Up the Receiver . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 Powering the IFL. . . . . . . . . . . . . . . . . . . . . . .
2.1 Setting up the Transmitter 2.1 Setting up the Transmitter 1. Place the 7870T in the 7180M Chassis. 2. Apply AC power to the chassis. The Power Supply and Laser LEDs should be lit. 3. Using an optical power meter, measure the optical power. Insert the meter’s cable into the Transmitter’s optical connector. Power levels should be 0.5 mW minimum (-3 dBm).
2.2 Connecting the Fiber Optic Cable 2.2 Connecting the Fiber Optic Cable Before connecting the cable: 1. The fiber optic cable must be either fusion spliced or connected via FC/APC connectors. 2. Wipe the connector with a lint-free cotton cloth. 3. Note the polarity key of the optical connector before inserting. To connect the cable: 1. Line Up the Polarity Key. 2. Insert the connector 3.
2.3 Setting Up the Receiver 2.3 Setting Up the Receiver 1. Place the 7870R Receiver in any of the 7180M Chassis, unless a 2040 RF Switch is installed. (See Figure 7 7180M Chassis Rear View on page 12.) Note If a 2040 RF Switch(es) is being installed, then slots 2 and/or 5 of the 7180M are reserved for the switch(es). 2. Apply AC power to the chassis. The Power Supply’s LED should be lit. 3. Using an optical power meter, measure the optical power coming to the Receiver from the fiber optic cable.
2.4 Powering the IFL 2.4 Powering the IFL • • • • Transmitter power requirement: +14 VDC @ 200 mA Receiver power requirement: +14 VDC @ 250 mA. The Standalone Transmitter/Receiver is powered by a Foxcom supplied external DC power supply. The Rackmount Transmitters/Receivers are plugged into the rackmount chassis. The chassis can accept and power up to eight units. Note At temperatures below10°C, the Transmitter’s internal heater will require an additional 100 mA.
2.4 Powering the IFL 2.4.1 7180M Chassis The 7180M Chassis provides power to the plug in units. The power supply is a switching type. Each plug-in regulates its own voltage.
2.5 Connecting the Back Panel Jumpers 2.5 Connecting the Back Panel Jumpers On the rear panel of the 7180M Back Panel are product selectors (JP1 to JP4). The 3 pin selectors (male) are the connecting point between the slots and the back panel. One pin is for the transmitter/receiver (Tx/Rx), one is for the optional 2040 1:1 Redundant Switch, and one is for the 7180M. A 2 pin jumper (female) is placed on the relevant pins to complete the connection between the 7180M and the units.
2.5 Connecting the Back Panel Jumpers 4. If the 2040 Switch is installed in Slot 5, place the JP1 and JP2 jumpers on the lower two pins and the JP3 and JP4 jumpers on the higher two pins. Figure 10 Jumper Installation: 2040 Switch in slot 5 5. If the 2040 Switch is installed in Slots 2 and 5, place the JP1, JP2, JP3, and JP4 jumpers on the higher two pins.
2.6 Aligning the Fiber Optic Link 2.6 Aligning the Fiber Optic Link The final step in installing the 7870 Interfacility Link is re-adjusting the Receiver Gain Control for unity gain. To set the unity gain (standard version) 1. Set the Signal Generator to -15 dBm. Alternatively measure the operational input level. 2. Set up the system as shown in Figure 12 Fiber Optic Alignment Setup 3. Adjust the Receiver Gain Control for -15 dBm reading on the power meter.

3.4 7180M Chassis Pinouts 3.4 7180M Chassis Pinouts The unit’s pins are found at the backplane of the 7180M chassis. The 7180M chassis backplane incorporates eight slots. Pinouts from the 9-pin connector at each slot are sent through the backplane assembly to the two 25-pin D-connectors, J12 and J13, and one 9-pin connector, J113. Any monitor voltages to be measured may be done between the chassis ground and the required pin.

4 Troubleshooting The 7870D Interfacility Link unit was tested before it left the factory. However if you are experiencing difficulties see the list below for possible solutions. if you are still experiencing problems, attempt to isolate and identify the malfunctioning unit before consulting Foxcom’s technical support. Table 8 Troubleshooting the Transmitter Problem Possible Cause 1. Laser LED not on a. No DC power to the unit. Possible power supply problem or AC power input problem.
Table 9 Troubleshooting the Receiver Problem Possible Cause 1. Lack of RF signal present at Receiver, yet optical power is functioning. If a spectrum analyzer or power meter is not available then use a DVM and adjust the gain control for RF signal strength (RSSI) so that the reading is > 0.2VDC. (See Table 5 7870R Receiver Pinout on page 21). Conclusion: If signal still not present then transmitter input stage amplifier or receiver amplifier is defective. Contact factory. 2. No optical power, a.
