13 Chapter 2 Overview of AT3300G Analog Transmitters This chapter provides a functional overview of Aurora Network s AT3300G Series Analog Transmitters. 2.1 Functional Overview AT3300G series analog transmitters are full-depth modules (Figure 2-1) that plug into any CH3000 chassis. AT3300G transmitters take RF inputs in the range of 46 to 1002 MHz, and output a 1310 nm optical signal. The current AT3300G models are listed in Table 2-1. See Chapter 4 for detailed specifications. AT3300G module status is displayed by front panel LEDs. A laser safety key switch and laser status LED are located near the bottom of the front panel. The 20 db test point is used for setup and troubleshooting. Each AT3300G transmitter is shipped with a companion BP-A1 or BP-A8 back plate that includes input (F-type) and output (SC/APC) connectors. The back plates are described in more detail in Chapter 3 Installing AT3300G Analog Transmitters. Figure 2-1 AT3300G Series Analog Transmitters AT33**G AT3300G-E-1-AS or AT3300G-N-1-AS (single RF input) Broadcast and Narrowcast RF input 1310 nm optical output +3 to +15 dbm depending on model AT3300G-A-2-AS or AT3300G-N-2-AS (two RF inputs) Narrowcast RF input (top) Broadcast RF input (bottom) 1310 nm optical output +3 to +12 dbm depending on model TM Rev.

14 AT3300G Series Analog Transmitters AT3300G transmitters are full-depth modules (13 inches deep) and can be plugged into the front or back of a CH3000 chassis (Figure 2-2 and Figure 3-3). AT3300G transmitters get +12 VDC power and management commands through the chassis midplane. The AT3300G transmitters offer high packaging density, where up to 12 transmitter modules can be installed in a single 3 RU high (5.25 inches) chassis with redundant power supplies. AT3300G transmitters can be managed locally from the chassis management display on PS3xxxD power supplies, or from Aurora s CMS (craft management software) or OTS (shelf management software) applications. Figure 2-2 CH3000 Chassis Table 2-1 lists the AT3300G models are covered by this guide. The xx in AT33xx model numbers indicates the optical output power. For example, an AT3312G-E-1-AS has an optical output of 12 dbm.

17 Chapter 3 Installing AT3300G Analog Transmitters This chapter describes the installation of AT3300G analog transmitters in a CH3000 chassis. 3.1 Planning Your Installation Plan your installation, and document the plan, before you install any hardware. Consider the following: Locate AT3300G transmitters close to related system equipment to enable easiest optical cable connections and troubleshooting. Locate AT3300G transmitters for optimum fiber optic cable routing, taking advantage of existing cable management hardware and cableways. Locate AT3300G transmitters for optimum service access to troubleshoot and install/remove. Locate AT3300G transmitters away from heat sources (operating temperature is 20 C to +65 C). Build in capacity for the future when practical, to allow for system growth and spare module availability. 3.2 Setting RF Input Levels for AT3300G Transmitters RF input levels are set on equipment that is upstream from Aurora s AT3300G transmitters. Refer to that equipment manufacturer s documentation for specific setup procedures. The RF input to AT3300G transmitters consists of a number of discrete channels. All input channels should be set to the levels shown in Table 3-1, using a spectrum analyzer. The composite RF can be measured with an RF power meter at the 20 db test point on the AT3300G front panel, or directly at the RF cable connector that connects to back plate BP-A1 (for a single RF input) or BP-A8 (for two RF inputs). For transmitters with two RF input ports (AT33xxG-A-2-AS and AT33xxG-N-2-AS), inputs connected to the narrowcast port (NC RF INP) are attenuated by 6 db relative to inputs to the broadcast port (BC RF INP). This occurs inside the transmitter and requires no operator action. See Table 3-1 for recommended input levels. Figure 3-1 Setting RF Input Levels for AT3300G Transmitters AT3300G-A-2-AS or AT3300G-N-2-AS (two RF inputs) Narrowcast RF input (top) Broadcast RF input (bottom) -6 db 1310 nm optical output +3 to +15 dbm depending on model TM Rev.

19 Installation and Activation Guide 3.3 Installing AT3300G Analog Transmitters AT3300G transmitters are hot-swappable and can be installed or removed from a CH3000 chassis with power on. They are full-depth modules (13 inches long) and can be plugged into the front or back of the CH3000 chassis (Figure 3-3). Each AT3300G is shipped with a companion back plate BP-A1 (for a single RF input) or BP-A8 (for dual RF inputs) that includes RF input (F-type) and optical output (SC/APC) connectors. The AT3300G transmitters offer high packaging density, where up to 14 transmitters can be installed in a single chassis. With redundant power supplies, you can still install up to 12 transmitters.

20 AT3300G Series Analog Transmitters To install AT3300G transmitters: 1. Inspect AT3300G transmitters and BP-A1 or BP-A8 back plates for any obvious damage. If a transmitter module appears to have been damaged in shipping or handling, contact the shipper and Aurora Networks or our local representative or reseller. 2. Determine which slots the AT3300G transmitters and corresponding BP-A1 or BP-A8 back plates will be installed in. For example, if an AT3300G transmitter is installed in slot 4, the back plate must be installed in slot 29. Conversely, if the AT330 is installed in slot 29, the corresponding back plate must be installed in slot 4. Figure 3-4 Installing AT3300G Analog Transmitters AT3300G Analog Transmitter Plunger (retracted) Grommet BP-A1 back plate BP-A8 back plate Dust cap Module front panel -20 db RF test point Optical output SC adapter RF input F-Type connector Remove the dust cap from the SC/APC connector on BP-A1 or BP-A8 back plate (Figure 3-4). Pull the two fastener plungers out to the retracted position. Position the back plate at the appropriate slot (in the CH3000 chassis). Push the plungers in to hold the back plate in place. 12 TM Rev.

21 Installation and Activation Guide Personnel safety must be everyone s first concern. When connecting fiber optics, know where (what equipment) specific fibers originate from and what power levels may be present. Shut the laser/led source(s) off whenever possible. Use an optical power meter or optical spectrum analyzer when in doubt as to power levels at a fiber optic connector. DANGER: Laser Radiation Avoid direct exposure to laser beams. Do not look into a fiber optic connector or view a laser beam directly with an optical instrument. Laser light, visible or invisible, can seriously injure eyes, or even cause blindness. CAUTION! If the power at a fiber optic connector is 5 dbm or greater, turn the optical source off before cleaning the connector. Cleaning a fiber optic connector with a signal level of 5 dbm or greater present can damage the fiber. RF input levels should be set as described in section 3.2 before connecting the RF cable(s) to back plate BP-A1 or BP-A8. 4. Connect the RF input cable(s) to the F-type connector on the back plate. Connect the optical output cable to the SC/APC connector on the back plate. 5. Insert the AT3300G into the CH3000 chassis. Verify that the corresponding BP-A1 or BP-A8 back plate is in place. AT3300G LED behavior should be as shown in Table 3-2.

27 Installation and Activation Guide Setting RF Input Attenuation from the Chassis Management Display If the input RF levels to the AT3300G have been set correctly (see section 3.2) the RF input (inside the AT3300G) will read 0 db. If the RF input is high, use the input attenuator to lower it to the desired level. The default attenuator value is 0 db. To view the RF input level and set attenuator: 1. From the top level, press to select the applicable slot. 2. Press, then to select STATUS (#1 on display map Figure 3-6). 3. Press, then to select RFlevel. If RFlevel shows 0 db, go to section and set RF Min and Max alarms. If RFlevel shows a positive value (greater than 0 db), go to the next step and add attenuation. If RFlevel shows a negative value (less than 0 db), double check the RF input levels (per section 3.2). 4. Press, then to select CONTROL (#2 on display map Figure 3-6). 5. Press, then to select INP Att (input attenuator). 6. Press, then to select the appropriate attenuation value. For example, if RFlevel was +4 db in step 3, set the INP Att to 4 db. The attenuator range is 0 to 6 db. Adding attenuation here lowers the RF drivel to the laser (inside the AT3300G). It does not change the RF input level to the AT3300G (at back plate BP-A1 or BP-A8). 7. Press to confirm your attenuator selection. Always reset RF Min and RF Max alarms (section 3.5.3) after setting the input attenuator. TM Rev. B 19

31 Installation and Activation Guide 3.6 AT3300G Setup from Software You can manage AT3300G transmitters from CMS (craft management software) or OTS (shelf management software). Use CMS to manage the AT3300G transmitters locally. To use CMS, connect the serial cable (part number ) from a COM port on a PC to the Serial port on the front of a PS3xxx power supply in the CH3000 chassis the transmitters are installed in. Use OTS to manage the AT3300G transmitters via the network. To use OTS, connect via the network by entering the IP address of the CX3001 in the CH3000 chassis the transmitters are installed in Software Compatibility To manage AT3300G transmitters effectively you must use compatible software (CMS or OTS). See Table 3-5 for the minimum acceptable software versions of CMS or OTS and CX3001. CX3001 software is only relevant when using OTS to manage transmitters. Software compatibility is important incompatible software (software versions older than specified in Table 3-5) may appear to work, but can give invalid results. For software versions newer than specified in Table 3-5, you may see minor differences in some dialog boxes.

49 Chapter 5 Cleaning Fiber Optic Connectors This chapter describes how to clean fiber optic connectors and adapters. Cleaning materials are listed, and both wet and dry cleaning methods are described. DANGER: Laser Radiation Avoid direct exposure to laser beams. Do not look into a fiber optic connector or view a laser beam directly with an optical instrument. Laser light, visible or invisible, can seriously injure eyes, or even cause blindness. CAUTION! If the power at a fiber optic connector is 5 dbm or greater, turn the optical source off before cleaning the connector. Cleaning a fiber optic connector with a signal level of 5 dbm or greater present can damage the fiber. 5.1 Introduction Many fiber optic system problems can be traced to dirty connectors or faulty connections. For best results, use the cleaning procedures offered here, or procedures prescribed by your facility/employer. The general area around fiber optic equipment should be maintained as clean as possible to minimize the risk of connector contamination. The diameter of the fiber core of a single mode fiber is about 8.2 µm. Dust, oil and other particles can easily be larger than 1 µm and could cause significant optical losses and other impairments in transmission performance. 5.2 Handling Fiber Optic Cables and Connectors Use the following guidelines when handling fiber optic cables and connectors: Avoid touching the end of a fiber connector with your fingers or any surface other than the mating connector. Keep dust caps on connectors when the connectors are not being used. Air dust the caps before reuse. Mate fiber optic connectors only with other connectors of the same type (APC to APC, UPC to UPC). That is, an APC (angled polished connector) should only be mated with another APC connector. Physical connector damage will result if a UPC (ultra polished connector), which has a flat polished end surface, is mated with an APC connector. To avoid fiber breaks, do not pull, twist, crimp or apply excessive stress to the fiber cable. Avoid excessive tilting of the connector during insertion of the connector to prevent damage or scratching of the fiber end. TM Rev. B 41

50 AT3300G Series Analog Transmitters 5.3 Inspection Equipment and Cleaning Materials The following inspection equipment and cleaning materials are recommended: Hand held optical inspection fiber scope (400x recommended) microscope (Figure 5-1) or video fiber scope (not shown). Connector cleaner cassette (Figure 5-2 A). 2.5mm cleaning sticks or 1.25 mm sticks: CLETOP cleaning stick is recommended. Do not use cotton Q-tips (Figure 5-2 B). Cotton swaps leave residues and threads behind. Chemtronics ES 1020 canned filtered air (0.02µm) (Figure 5-2 C). Lint-free cloth/paper such as Kim Wipes (Figure 5-2 C). Solvent dispenser and optics grade (>99% pure) Isopropyl alcohol. Figure 5-1 Fiber Scope Figure 5-2 Connector Cleaning Materials A B C 42 TM Rev. B

51 Installation and Activation Guide 5.4 Inspecting Fiber Optic Cables and Connectors DANGER: Laser Radiation Avoid direct exposure to laser beams. Do not look into a fiber optic connector or view a laser beam directly with an optical instrument. Laser light, visible or invisible, can seriously injure eyes, or even cause blindness. Optical connectors should be inspected for cleanliness using a viewer such as the fiber scope shown in Figure 5-1. For eye safety, make sure light sources are turned off. Special adapters may be required to inspect the various types of optical connectors (SC, FC, LC). Ensure that the adapters themselves are cleaned first, as dirt can easily migrate or transfer from one surface to another. Figure 5-3 shows some typical examples of connector contamination and damage: Clean connector (Figure 5-3 A). Connector with dirt such as dust particle (Figure 5-3 B). Connector with oil such as fingerprint oil (Figure 5-3 C). Connector with scratches (Figure 5-3 D). Figure 5-3 A Fiber Optic Cable with Typical Faults B C D A connector withdrawn from a mating sleeve (adapter) that is found contaminated would usually indicate that the other side of the mating connector is contaminated also. Therefore, both connectors and the adapter should be properly cleaned before re-mating them. TM Rev. B 43

52 AT3300G Series Analog Transmitters 5.5 Cleaning Procedures Every fiber optic end face should be cleaned before each connection. Ensure that optical power is turned OFF before cleaning a connector. CAUTION! If the power at a fiber optic connector is 5 dbm or greater, turn the optical source off before cleaning the connector. Cleaning a fiber optic connector with a signal level of 5 dbm or greater present can damage the fiber Connector Cleaning Dry Method Perform the following steps to clean fiber optic connectors using the dry method (see Figure 5-4). Use CLETOP or lint-free tissue/cloth to wipe gently across the connector end-face. Do not apply excessive pressure to scrub off dirt unless repeated attempts had failed. Do not use the edge of the lint-free tissue/cloth to clean a connector. When picking up a piece of lint-free tissue, use the side that s facing down for cleaning. Do not use the same area of the lint-free cloth/tissue more than once. When using CLETOP, slide the connector only once over the cleaning surface. If the end-face is still dirty, proceed to wet-cleaning (section 5.5.2). Figure 5-4 Connector Cleaning Dry Method 44 TM Rev. B

53 Installation and Activation Guide Connector Cleaning Wet Method Perform the following steps to clean fiber optic connectors using the wet method (see Figure 5-5). Wipe the dispenser clean with lint-free tissue/cloth. When picking up a piece of lint-free tissue, use the side that s facing down for cleaning. Do not use the same area of the lint-free cloth/tissue more than once. Moisten the lint-free tissue/cloth with Isopropyl alcohol (>99%) and draw it across the end-face of the optical connector. Use a dry lint-free tissue/cloth to wipe it dry. Do not let the surface air dry, as this may result in residue being left behind on the connector. Figure 5-5 Connector Cleaning Wet Method After cleaning, connect the fiber end to the intended port or device to minimize air exposure with possible contamination. If the end-face of the fiber jumper is damaged or scratched beyond cleaning or repair, replace the fiber jumper with a new one whose end-faces are acceptable Adapter Cleaning Using pressurized canned air, such as Chemtronics ES 1020, blow away any dust particles that may be on the interior surface of the adapter, particularly the inside walls of the alignment sleeve. Hold the can approximately 2 inches from the receptacle to be cleaned and apply 2-3 short blasts of air. Short burst should be used; long burst of air may cause condensation to form. Do not shake or invert the pressurized can before or during use. Do not apply pressurized canned air directly to end surface of a connector. In most cases, this is sufficient for cleaning an adapter. However, if some dust particle still adhere to the interior surface, wet cleaning might be required. To wet-clean the adapter, moisten the end of a swab (CLETOP stick highly recommended) with isopropyl alcohol, and insert it into the adapter. Insert the moistened swab fully into the bulkhead and rotate the swab back and forth 90 degrees twice, twisting the swab between your thumb and finger to assure a thorough cleaning. Remove and discard the swab. Do not use the same swab on more than one adapter. Dry the inside of the receptacle by holding the pressurized canned air approximately two inches from the end of the bulkhead and apply two or three short blasts of air. TM Rev. B 45

54 AT3300G Series Analog Transmitters Transceiver Interface Cleaning Use the following procedure to clean optical ports on TR4000-PI (and similar) plug-in optical transceiver modules. When using compressed air, do not shake the can. Hold the can upright and apply short bursts only, as mentioned in adapter cleaning section above. Do not apply compressed air directly into the receptacle where the connector ferrule would enter. Direct air to the surrounding outer perimeter to reduce potential contaminants from entering into the optical interface. Moisten a clean, unused CLETOP stick with Isopropyl alcohol (>99%). Shake off excess alcohol. Gently insert the stick into the receptacle sleeve and rotate it twice (Figure 5-6). Do not to apply excessive force when pushing the stick into the receptacle. Discard the stick and insert a new clean CLETOP stick and again, rotate it twice. You can use a video inspection scope to verify transceiver interface cleanliness. The operation can be repeated. If you cannot get the interface clean after multiple tries, or the interface doesn t work when connected, contact customer support.
