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 7225H IFL is a DFB high dynamic range link for applications that require either a higher quality link or transmission over long distances. The 7225H IFL consists of an optical transmitter (7225HT) which receives the L- Band signal from the LNB and an optical receiver (7225HR) which connects to a satellite receiver. The 7225HT and 7225HR modules plug into the 7180M, a 3U chassis/power supply, which enables expansion of the system to accommodate any eight Sat-Light modules. Accessories include the Model 7001P Power Supply, the Model 2040 1:1 Redundant Switch, the Model 2100 Amplifier, the 2380 Relay Adaptor, and the Model 7050 Serial Optical Multiplexer, an asynchronous data link. The 7225H 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. Featuring a Multi-Quantum Well (MQW) laser diode, the 7225H IFL operates over a wide temperature range, without needing to be cooled. Slow start optical power control protects the laser from DC transients upon turn-on. Gain Control provides for optimization of the RF signal. LEDs, and back panel monitors and alarms allow for complete system status monitoring and for interfacing with monitor and control (M&C) systems.

1.1 Options The 7225H Interfacility Link comes with a variety of options: 1. 155nm laser; a 1310 nm laser is standard. 2. LNB powering; the transmitter unit can provide 14 or 18 VDC for optional LNB powering, depending on the Power Supply in the chassis1. 3. 50 Ω or 75 Ω Input/Output Impedance/BNC female connector. Standard impedance is 50 Ω/F type, female connectors. 4. Standalone unit; the 7225H Interfacility Link can be installed as a standalone unit. If the 7225H is used as a standalone, a separate power supply must be used. 5. On the side of the 7225HT and the 7225HR units is a label which lists options 1 to 3. Under each option is a square2. If the unit includes a particular option the square under the option should be marked. Figure 1 Option Label 1. At least one power supply, either a 14 VDC or an 18 VDC, depending on customer specifications, must be installed in the 7180M chassis. Up to two rackmounted power supplies may be installed on the chassis. The two power supplies must have the same voltage, either two 14VDC or two 18 VDC. External Power Supply: An external power supply may be used.The external power supply is connected via connector J11. If an external power supply is used this must be specified when ordering the7225H and the chassis. The voltage level provided by the external power supply is customer-defined any may be different from the internal voltage power supply. 2. The label includes options which are not relevant to the 7225H Interfacility Link.

page 10 Document no. 93-005-33-B2 2.3 Setting Up the Receiver 1. Place the 7225HR Receiver in any of the 7180M Chassis, unless a 2040 RF Switch is installed. (See Figure 8 7180M Chassis Rear View on page 12.). Note If a 2040 RF Switch(s) 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. On the rear panel connect the fiber optic cable from the De-Mux to the Optical Connector. The Opt. LED should be lit (if the Transmitter is operating correctly). 4. 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 loss4. Alternatively, use a DVM to measure the voltage at: • pins J13-P7 through J10-P12 for the slot being measured (See Table 5 7225HR 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) 5. On the rear panel, connect the coax cable to the RF Output Connector. 6. 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 2.7 Aligning the Fiber Optic Link on page15. 2. If the LED is not lit, see Chapter 5: Troubleshooting, on page 29. 4. Fiber loss is defined as: (attenuation/km x length (km) of the fiber optic cable) + (1.0 dB x 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 x 10 km) + (0.5 dB x 2) = 5.0 dB

7225H Interfacility Link Installation and User’s Guide page 11 Foxcom proprietary information 2.3.1 Measuring the RF Signal Strength The RF signal strength can be monitored during operation via a DC RF signal-strength monitor. Maintenance personnel can perform a simple verification process. To measure the RF signal strength: • Rackmount Connector: Using a Digital Volt Meter, measure the voltage at J13-P1 through J13-P8. • 2380 Relay Adapter: Using a Digital Volt Meter, measure the voltage at J4-P1 through J4-P8. • Standalone: Using a Digital Volt Meter, measure the voltage at the connector pin #4. The nominal level is 3 to 4 VDC. 2.4 Powering the IFL • Transmitter power requirement: 14 or 18 VDC 5@ 270 mA (excluding LNB Drive option). • Receiver power requirement: 14 or 18 VDC 5. @ 360mA. • 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 below -10° C, the Transmitter’s internal heater will require an additional 120 mA. The Transmitter’s total power requirement will then be 390 mA. Caution Ensure that there is a good airflow around the chassis rackmount. 5. At least one power supply, either a 14 VDC or an 18 VDC, depending on customer specifications, must be installed in the 7180M chassis. Up to two rackmounted power supplies may be installed on the chassis. The two power supplies must have the same voltage, either two 14VDC or two 18 VDC. External Power Supply: An external power supply may be used.The external power supply is connected via connector J11. If an external power supply is used this must be specified when ordering the 7225H Interfacility Link and the chassis. The voltage level provided by the external power supply is customer-defined any may be different from the internal voltage power supply.

7225H 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: • 15 or 18 VDC stable • AC input; 100 - 240 VAC • Units can be plugged in “hot standby” Figure 7 7180M Chassis Rear View

7225H 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 27 Foxcom proprietary information 4 Gain Control The 7225H IFL unit requires no maintenance, but the user can adjust the transmitter and receiver gain by 20 dB. The gain can be between 0 to -20 dB. All internal adjustments have been set up at the factory; the only user adjustments are input and output RF signal levels accessible from the front panel and described in the following sections. A detailed procedure for optimizing the gain control is provided in section 2.7 Aligning the Fiber Optic Link on page15. If you do not have a signal generator or spectrum analyzer, adjust the gain according to the following procedure. To adjust the Transmitter Gain: 1. Set the input power to the expected power level. 2. Set the nominal RSSI signal at 3.5 V ± 0.5. To adjust the Receiver Gain: 1. Set the input power to the expected power level. 2. Set the nominal RSSI signal at 5.0 V ± 2.

page 29 Foxcom proprietary information 5 Troubleshooting The 7225H 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. 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 -4.8 and -4.2VDC. 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 2 to 5 mW [+3 to 7 dBm]. If an optical power meter is not available, use another receiver to determine if there is optical power emerging from the transmit- ter (use a 5 meter jumper cable). If there is no optical power, then the transmitter unit is malfunctioning. If any or all the above are not within the guidelines, the transmitter unit is faulty. 2.Lack of RF signal present at Receiver, yet optical power is functioning. a.If the unit has an LNB drive option, verify correct LNB bias is coming down the center of the RF connector at the transmit site. b.Verify dish is pointed and correctly receiving satellite signals. Conclusion: If signal still not present then transmitter input stage amplifier is defective. Contact factory. Table 9 Troubleshooting the Transmitter

3.No optical power, LED not illuminated a.No optical power, LED not illuminated.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. 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. 4.Optical power light illuminated with disconnected optical input. Leaky photodiode or DC Amplifier offset. Unit may still function, otherwise contact factory. Table 9 Troubleshooting the Transmitter

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. Description Manufacturer Kim wipes Kimberly Clark Cletop Automatic Connector Cleaner Cletop fiber optic Swab Cletop or FIS fiber optic Compressed Air Chemtronics Table 10 Cleaning materials

Appendix 1.1 Cleaning Procedures for FC/APC Connectors Use a Kim Wipe to gently wipe the end face surface of the connector. Alternatively a Cletop automatic connector cleaner can be used. Figure 19 Wiping the connector with a Kim wiper Figure 20 Wiping the connector with a Kim wiper [2]

page 33 Foxcom proprietary information Appendix 1.2 Cleaning Procedure for FC/APC Bulkhead Ports Caution Clean the transmitter and receiver optical ports only when there is evidence of contamination or reduced performance. Appendix 1.2.1 Swab Method Using a clean fiber optic cleaning swab, gently wipe out the optical port. Discard the swab after use. Figure 21 Cleaning the Optical Port Figure 22 Cleaning the Optical Port [2] Appendix 1.2.2 Compressed Air Method Using the extension tube of the compressed air, blow into the port to remove any dust or debris. Do not allow the tube to touch the bottom of the port. Do not use commercial compressed air due to potential oil contamination. Note To prevent contamination, the optical ports should be connected or covered with a dust cap at all times. Use dry air or nitrogen only.
