Setup Minimum Computer Requirements

• 486DX 66 MHz PC with 32 MB RAM • Windows 98/2000/NT • Serial port Software Installation

1. Log on as Administrator or as a user with administrator privileges. This is required on some Windows 2000 and Windows NT systems. 2. Insert the JDSU CD into a CD drive. The installation will start as soon as the disk is recognized. If the installation does not start on its own, run the setup.exe file located in the Install folder on the CD, and follow the on-screen directions. A system restart may be required after installation. Hardware Setup

Attention Make sure that the evaluation board is not powered while inserting or removing the Transponder. Danger Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view directly with optical instruments. Viewing the Transponder output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure. ESD Caution Although the JDSU 7100 is a highly robust product, it is recommended that you take appropriate ESD precautions when installing, using, or removing the Transponder. 1. Insert the Transponder into the Evaluation board Connector J201. If the Transponder is to be used in 300-Pin Electrical Loop Back, insert the Loop Back board into the Evaluation board Connector J301. 2. Connect the serial port of the PC to the I2C™ converter module, as shown in Figure 2. 3. Plug the power supply into the wall power outlet. The supply operates over a wide AC input range from 115V to 230V at 50/60 Hz. Power supplies are labeled according to their operating range. The DC output voltage of the supply is +5.0V. 4. Plug the DC power connector into the evaluation board (Figure 2). The green LEDs labeled +5V, –5.2V, and +1.8V, 3.3D, +3.3A, and +3.3V should light up. It is normal for several red LEDs to also light at power-up; these will clear after the Transponder is initialized and configured for operation. 5. To remove the Transponder from the Evaluation board, disconnect the power and then pull the Transponder up from the socket.

3. The Evaluation board has several alarm indicators. When the unit is first turned on, the alarms engage. Once the boot sequence is complete, all alarms will be turned off if the Transponder is configured correctly and is receiving an appropriate signal. 4. Make sure that the Transponder is powered. Connect the Optical Fiber input and output ports. Make sure that none of the Optical Power levels exceed specifications for the Transponder or for the Test setup. Make sure the Loop Back board is in place. 5. There are several switch settings on the evaluation board. The factory default settings for these switches are configured to provide 300-Pin Electrical Loop Back. Figure 4 shows the configurations when the Transponder is used in Soft mode or Hard mode. When the Transponder is tested in Electrical Loopback, switches S601 thru S607 and S701 are used. SMA connectors J701 thru J703 and J711 should not be used.

6. Operation Modes Provisions have been made to provide TxREFCLK and RxREFCLK to the Transponder, if it is tested in an operating mode other than Electrical Loopback. The clocking options are pictured in the block diagram of Figure 5. All of these options are configured via switch S701 (Figure 6). The module out-of-the-factory is configured for hard mode. In hard mode, the switches are used to configure the unit. To use the software (or GUI interface) for configuration, the module must be placed in soft mode. Mode changes can be done using the Configuration menu. Refer to the JDSU 7100 Series 10 Gbps DWDM Universal Transponder Instruction Command Set document for further details on modes of operation. For convenience, the Force Soft Mode selection may be used to place the module in soft mode. This is true from any mode (hard, allocate, or soft).To return to hard mode, just select Enter Hard Mode.

Troubleshooting/FAQ When I try to send commands, the response code is ERR, and TIMEOUT appears in the response box. • Make sure that the evaluation board is powered and the I2C™ cable is connected securely. There is no power or too little power coming out of the Transponder. • Make sure that the power supply is on and connected correctly. • Make sure that a channel has been selected. • Check to make sure that the fiber optic connector is clean and your splice is intact. • Make sure that the LsENABLE switch is in the enable mode. • If operating in soft mode, check that the LsENABLE option in the Tx register is enabled. The Tx register settings are available on the Command-Transmit tab. The output power/wavelength is unstable. • After turning the Transponder on, please allow it to warm up for 2 minutes before evaluating output stability. There is no stabilization time required after switching channels. What is the optical output power variation from channel to channel? • Between channels, the output power variation is ± 0.5 dB through end of life. For a single channel, the output power variation is ± 0.5 dB over temperature and through end of life. What happens when I change channels? Is any stray light emitted into other channels? • No stray light is emitted into other channels. A blanking procedure is used during the channel switching process. The blanked power level is less than –30 dBm. A pre-lock process ensures that the output power is always below –30 dBm until the new channel has been selected with an accuracy of ± 10 GHz. The power is then ramped to the intended level with a frequency accuracy of ± 3 GHz at end of life. What are the aging characteristics of JDSU Transponders? • Contact your JDSU Field Applications Manager for a tunable laser qualification report and reliability white papers.

Handling Considerations Although the Transponder has been designed to be physically robust, use care during handing and installation. Package

• Because the complete Transponder is not hermetically sealed, do not immerse it or spray it with cleaning solutions or solvents. • Take appropriate ESD precautions when installing, using, or removing the Transponder. • Protective plastic caps are provided for the 300-pin connectors on the test board, transponder, and loop back board. Place caps over any exposed connector to protect pins from damage. • Do not use screws longer than 3 mm when mounting a heatsink to the Transponder. Fiber and Connector

• The fiber connector handling/protection cap and the fiber pigtail materials can deform at temperatures above +85°C. • Keep optical connector clean and free of surface particles. Keep the optical connector handling/protection cap in place when the fiber pigtail is not mated. Oil-free canned air or nitrogen with an extension tube may be used to help remove surface particles. • Observe normal industry procedures for handling and cleaning. Use care in controlling the minimum fiber bend radius (25 mm). • Make sure that the protection cap is debris-free and clean prior to reinstalling it on the optical connector. • Do not use the fiber boots as a means of support while moving or carrying the Transponder. Optical Fiber Boots are not designed to support the weight of the Transponder; misuse will result in performance degradation.
