Installation and Setup Installation and Setup This section provides instructions on how to install the GX2-EA1000C*/*, connect it to other equipment, select the operating mode, and verify its operation. To function, the GX2-EA1000C*/* requires a GX2-HSG* equipment shelf configured with a GX2-PSAC10D-R or GX2-PSDC10D-R power supply and a GX2-CM100B control module. -
Page 26: Unpacking The Gx2-Ea1000C
Unpacking the GX2-EA1000C*/* 1. Unpack the GX2-EA1000C*/* and inspect it for damage. If damaged, set it aside in its original packing material and contact the Motorola Customer Service department for further instructions. See Section 1, “Introduction.” 2. Record the model number, serial number, and related information for future reference. -
Page 27: Cleaning The Gx2-Ea1000C*/* Optical Bulkhead Fitting
Installation and Setup The GX2-HSG* is now ready to accept the GX2-EA1000C*/*. However, before you insert the GX2-EA1000C*/* into the GX2-HSG*, you need to perform some basic cleaning procedures on the optical interfaces. It is highly recommended that the following cleaning procedures be performed prior to installing the GX2-EA1000C*/* in the GX2-HSG*. -
Page 28: Cleaning The Interface Fiber Jumper Sc/Apc Connector
Installation and Setup Figure 9: Cleaning the Barrel of the Optical Bulkhead Fitting Cleaning the Interface Fiber Jumper SC/APC Connector In addition to cleaning the optical bulkhead on the GX2-EA1000C*/*, it is also important to clean the interface fiber jumper optical connector(s). This cleaning should be performed before you insert the GX2-EA1000C*/* into the GX2-HSG*. -
Page 29: Inserting The Sc/Apc Connector
Installation and Setup Inserting the SC/APC Connector Before inserting the GX2-EA1000C*/* into the GX2-HSG*, insert the interface fiber jumper SC/APC connector into the optical bulkhead fitting. It is recommended that you use a short optical jumper for initial GX2-EA1000C*/* installation. This provides greater flexibility for installation and can be used to verify the optical output power after the unit is installed. -
Page 30: Installing The Gx2-Ea1000C*/* In The Gx2-Hsg
Installation and Setup DANGER! Subsequent to the initial installation, when any of the above optical cleaning procedures are performed, it is recommended that power be removed from the GX2-EA1000C*/* transmitter for your protection. Installing the GX2-EA1000C*/* in the GX2-HSG* You are now ready to insert the GX2-EA1000C*/* into the GX2-HSG*. All slots in the GX2-HSG* are universal and intended for the Omnistar GX2 application modules, except the narrow, right-most slot, which is reserved for the control module. -

The GX2-EA1000C*/* LED completes a red–yellow– STATUS green cycle. Upon initial power-up of a new unit, the GX2-EA1000C*/* conforms to the factory default Preset/Video mode with a 4 dB video mode offset from CW. -
Page 33: Measuring And Checking The Optical Output Power
Installation and Setup Measuring and Checking the Optical Output Power The following procedures for measuring optical output power and routine maintenance of the GX2-EA1000C*/* should be performed by properly trained personnel. In all cases they should be aware of and observe the following warnings associated with fiber optic transmitters: D A N G E R ! Laser Hazard! Invisible laser radiation when the module is operating and the interlock defeated. -
Page 34: Measuring And Checking The Rf Input Signal Levels

Page 36: Operating Modes
Installation and Setup Operating Modes Select the preferred GX2-EA1000C*/* operating mode, MGC or AGC. Reminder—on initial power up, the factory default is Preset/Video mode with a 4 dB Video mode offset from CW. The following subsections describe how to set up the GX2-EA1000C*/* based on the operating mode selected. -
Page 37: Agc Modes
Installation and Setup AGC Modes To implement AGC modes: 1. Adjust the input signal levels per the GX2-EA1000C*/* specification, as described previously in “Measuring and Checking the RF Input Signal Levels.” 2. If the BC and NC signals are both applied to the main input, the total CW input signal power should be approximately −14 dBm or +34.75 dBmV. -
Page 38: Operation
Operation Operation This section describes the GX2-EA1000C*/* embedded section, user selectable operating modes, and network management system, and provides information necessary to properly use the optional SDU. It also provides information on increasing and decreasing channel loading and, if necessary, how to download new GX2- EA1000C*/* firmware. -
Page 39: Agc Modes
Operation AGC Modes The following settings (submodes) are available in AGC: Preset Preset is a primary mode that establishes the factory default setting and maintains an ideal RF input level to the laser. The laser RF input level is maintained by (1) sampling the main RF-path power through an internal RF power meter, (2) comparing it to a factory-calibrated default AGC power level stored in NVM, and (3) adjusting the RF attenuator until the factory calibrated default AGC power level is achieved. -
Page 40: Mgc Modes
Operation CW/Video CW is a secondary mode that uses unmodulated channels for a proof-of-performance rating. Video is also a secondary mode that is used when modulated channels are applied to the input of the GX2-EA1000C*/*. CW and Video are used in conjunction with Preset and Set. -
Page 41: Additional Controls And Configurations
Operation Additional Controls and Configurations The following subsections describe additional features of the GX2-EA1000C*/*. Optical Output Control You can turn the optical output power from the laser diode ON and OFF using the local interface port, the network management system, or the optional SDU. The factory default setting is ON. -
Page 42: Implementing A Reduced Channel Load
Operation The GX2-EA1000C*/* reads the quick-swap message from the GX2-CM100B, automatically resets, and re-initializes itself to the same configuration as contained in the message. • If the GX2-EA1000C*/* is in Preset mode, it uses the factory default optimum OMI setting to determine the RF level at the laser. •... -
Page 43: Implementing An Increased Channel Load
Operation Implementing an Increased Channel Load Many systems operate under a reduced channel load with the capacity to add additional channels as required. If the system initially operated with less than a full load (79 NTSC channels from 52 through 550 MHz and 450 MHz of digital at –6 dBc from 550 through 1002 MHz) and you need to increase the channel load, you may have to decrease the RF input level per channel accordingly in order to maintain an optimum drive level to the laser. -
Page 44: Using Set Mode
Operation Using Set Mode To implement an increased channel load using Set mode: 1. Operate the GX2-EA1000C*/* in Preset mode and apply the preferred initial channel load. 2. Allocate time for the AGC to adjust the RF drive level to the laser. 3. -
Page 45: Using Preset Mode (With Agc Control In The Gx2-Ea1000C*/* Only)
Operation 4. Allocate time for the AGC to adjust the RF drive level to the laser and to adjust the levels at the nodes. 5. Apply the additional channel load. 6. Allocate time for the AGC to adjust levels to the new channel load. 7. -

Page 49: Full Spectrum Multi-Wavelength Application
With this recommendation, it would make sense for pay-as-you grow systems to start with Ch 29 or Ch 31 as a single wavelength and grow from there. Understanding the impacts of FWM, Motorola has incorporated functionality into the GX2-EA1000C*/* product line to reduce these issues by offsetting select channels within the ITU channel bandwidth. -
