page v Foxcom proprietary information Reporting Defects The units were inspected before shipment and found to be free of mechanical and electrical defects. Examine the units for any damage which may have been caused in transit. If damage is discovered, file a claim with the freight carrier immediately. Notify Foxcom as soon as possible. Note Keep all packing material until you have completed the inspection. Precautions Personal Safety OPTICAL RADIATION Applying power to the transmitter unit will create a laser energy source operating in Class I as defined by IEC 825-1. Use either an infrared viewer, optical power meter or fluorescent screen for optical output verification. AC POWER HAZARD The rackmount power supply line is EMI filtered. The chassis is connected to earth ground in compliance with safety requirements. Always use the 3-prong AC plug with earth ground to avoid possibility of electrical shock hazard to personnel. Equipment Safety To avoid damaging your product, please observe the following: 1. The output of the receiver is AC coupled and can withstand the bias from a satellite receiver. Do not exceed 25V DC bias. 2. The input of the transmitter has an optional built-in bias for inserting DC power up the coax to the LNB. Make certain that any equipment or test equipment connected to the transmitter input can withstand this bias. 3. Do not allow any dirt or foreign material to get into the optical connector bulkheads. This may cause damage to the polished optical connector end faces. 4. The optical fiber jumper cable bend radius is 3 cm. Smaller radii can cause excessive optical loss and/or fiber breakage. 5. If multiple transmitters are installed in the chassis allow sufficient room for adequate ventilation; otherwise the units may overheat causing possible safety hazard or equipment damage. 6. Fuses: The 7180M chassis does not have fuses. If the unit fails, pull the power supply out from the chassis and then push it back in. 7. When several units are installed on one 7180M chassis, ensure that the total units’ current consumption (including any LNB bias) does not exceed 6A.

The 7870 IFL consists of an optical transmitter (7870T) which receives signals from satellite modems, video modulators, or exciters and transmits them to an optical receiver (7870R) via singlemode fiber. The 7870T and 7870R modules plug into a 7180M, a 3U chassis and power supply, which enables expansion of the system to accommodate up to eight Sat-Light™ modules. Accessories include the Model 7001P Power Supply, the Model 2040 1:1 Redundant Switch, the Model 2100 Amplifier, and the Model 7050 Serial Optical Multiplexer, an asynchronous data transceiver. The 7870 IFL transmits all satellite modulation schemes - digital or analog. Any FM modulated RF signal is transmitted accurately. The RF signal is directly modulated and adds virtually no phase noise to the original signal. The direct modulation, along with extremely flat amplitude and group delay, guarantees low bit error rate (BER) and high signal quality, independent of distance. LEDs, and back panel monitors, and alarms allow for complete system status monitoring and for interfacing with monitor and control (M&C) systems. Gain Control at the Receiver sets the RF level.

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. If the unit includes a particular option the square under the option should be marked. Figure 1 Option Label 1. The sticker includes options which are not relevant to the 7870 IFL.

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. Tighten the connector Caution Do not apply any glue, silicon adhesive, or any other material to the fiber optic connector!

page 10 Document no. 93-005-35-C5 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. The power levels of the Receiver should be the power level measured at the Transmitter minus the fiber loss2. Alternatively, use a DVM to measure the voltage at: • pins J13-P9 through J13-P16 for the slot being measured (See Table 5 7870R Receiver Pinout on page 21 for details regarding J13 pinouts) (7180M Rackmount). The voltage level should be 1 V for each 1 mW measured at the Receiver input. • at pin #5 of the 9 pin connector (standalone) 4. On the rear panel, connect the coax cable to the RF Output Connector. 5. Adjust the Gain Control Potentiometer to give the desired output power. Using a small screw driver, turn the potentiometer (located on the front panel) to increase or decrease the gain. Notes 1. The potentiometer is 10 turn potentiometer. • To increase the gain, turn the gain control clockwise. • To decrease the gain, turn the gain control counterclockwise. For more information see 2.6 Aligning the Fiber Optic Link on page15. 2. If the LED is not lit, see Chapter 4 Troubleshooting on page 25. 2. Fiber loss is defined as: (attenuation/km x length (km) of the fiber optic cable) + (0.5 dB × number of connectors). For example if a signal with an optical wavelength of 1310 nm is transmitted over a link 10 kilometers long which had two connectors the loss would be: (0.4 dB/km × 10 km) + (0.5 dB × 2) = 5.0 dB

7870 Interfacility Link Installation and User’s Guide page 11 Foxcom proprietary information 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. The Transmitter’s total power requirement will then be 300 mA. Caution Ensure that there is a good airflow around the chassis rackmount.

7870 Interfacility Link Installation and User’s Guide page 12 Foxcom proprietary information 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. The power supply provides: • 14 VDC stable • AC input; 100 - 240 VAC • Units can be plugged in “hot standby” Figure 7 7180M Chassis Rear View

7870 Interfacility Link Installation and User’s Guide page 13 Foxcom proprietary information 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. For example, if a 2040 Switch is being used, the jumper is placed on the Switch-7180M pins. To connect the jumpers: 1. Each jumper has two sets of pins, upper and lower. The upper pins are labeled SW (Switch) and the lower pins Tx/Rx. 2. If the 7180M has Tx or Rx units only, place all jumpers on the lower two pins. Figure 8 Jumper Installation: Tx and Rx only 3. If the 2040 Switch is installed in Slot 2, place the JP1 and JP2 jumpers on the higher two pins and the JP3 and JP4 jumpers on the lower two pins. Figure 9 Jumper Installation: 2040 Switch in slot 2

page 25 Foxcom proprietary information 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. Check the power supply fuse. b.Verify LSRI monitor is between -4.2 and -4.8VDC. If not, laser may have overheated. Disconnect power or remove plug and allow to cool. Try again with better airflow. c. If an optical power meter is avail- able, measure the optical power out of the transmitter. The power should between 0.5 mW[-3 dBm]. If an optical power meter is not avail- able, use another receiver to deter- mine if there is optical power emerging from the transmitter (use a 5 meter jumper cable). If there is no optical power, then the transmit- ter unit is malfunctioning. If any or all the above are not within the guidelines, the transmitter unit is faulty. 2. The RF LED is not lit The input signal is less than -28 dBm; verify RF signal strength [RSSI] is≤0.2 VDC. [See Table 4 7870T Transmitter Pinout on page 20]. Even if slightly out of range, the unit may still function, although it will register an alarm condition. 3. RF LED illuminated - with no input signal Unit may be receiving stray RF “pick up”. Solution: provide RF input or use necessary termination input.`

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, LED not illuminated. a. Transmitter is not functioning, see above. b. There is a break or severe bend in the fiber optic cable. Use an optical power meter or another functioning receiver unit to verify optical power coming down the fiber. c. The connector is dirty. Clean it. d. Optical power too low, too many splits, too long a distance (thus exceeding optical budget). System may still function without LED illuminated although at reduced performance. 3. Optical power light illuminated with disconnected optical input. Damaged (leaky) photodiode. Unit may still function, otherwise contact Factory for service. 4. The RF LED is not illuminated. Verify that the RF signal strength (RSSI) is <0.2° VDC.

The units are specified into single mode fiber i.e. 9/125 micron core diameter. Full performance is specified only for low return loss optical plant - meaning that the fiber must be fusion spliced and all connections or splices must have a return loss greater than -60 dB. With these guidelines in mind, link lengths beyond 20 kilometers (DFB based products) can be achieved with high performance. Specific performance and/or design assistance is available by request from Foxcom. If there is low/no signal or noisy signal at a Foxcom module, the connector should be cleaned. Dirt on the inside connector tip can impair the flow of light causing problems in signal transmission. Foxcom modules are sealed but dirt can occasionally enter during installation and alignment. The input and output optical ports of all Foxcom equipment are known in the fiber optic world as bulkhead ports. Foxcom uses FC/APC connectors. The following materials are representative of the types of cleaning materials that should be used for cleaning the fiber optic ports and connectors. They are available from several suppliers. Wiping clothes should be made of lint free alcohol free nonabrasive materials. Swabs should have a tightly wrapped tip and be talcum- free. For removing dust from receptacles, a canned compressed gas is recommended. Do not use commercial compressed air because of risk of contamination.
