Page 14: General Information And Specifications
General Information and Specifications General Information This user’s manual for the RM3 Series Backreflection Meter contains complete operating instructions. The Backreflection Meter can be ordered as a single-mode or multimode model. Software is bundled with the meter; for information on using the software, see the Multiple Connector Test System Software User’s Manual (document SD000318). -
Page 15: Backreflection Measurements
Backreflection Measurements Reflections in optical systems can come from a number of sources. Primary sources include the fiber (Rayleigh backscatter) and Fresnel reflections that occur at the planar junction of two materials having different refractive indices, for example, connector and fiber end faces, splices, bulk optic interfaces, and detector surfaces. -
Page 16: Output Port
Output Port The output port of the Backreflection Meter is equipped with an ultra-low backreflection APC connector. To prevent damage to the output port connector, a measurement jumper must be used for all measurements, even for measuring a component with an APC connector. Internal Light Sources The Backreflection Meter can be equipped with two internal laser sources. -

Page 26: Termination Techniques For Single-Mode (980 Nm) And Multimode Fiber
1. Using the size of rod specified in the Inspection Report (see the Customized Features and Test Data section), wind the cable around the rod until the reading displayed on the Backreflection Meter no longer changes (approximately six turns). The diameter of the rod must be suitable for the type of fiber connected to the output port jumper and for the wavelength in use. -

6. Terminate the measurement jumper just before the output connector, and hold the termination point steady (figure 5a for single-mode (except 980nm), and figure 5b for single- mode (980nm) and multimode). NOTE: The termination technique is different depending on the type of the Backreflection Meter used: single-mode (except 980 nm), single-mode (980nm) or multimode. -
Page 29: Backreflection Accuracy And Range
1. Perform the BR measurement at least once per shift. The measured backreflection is affected by losses that can occur between the meter and the DUT. To compensate for these losses, measure the total amount of loss between the output of the measurement hybrid jumper and the input of the DUT (see the Loss and Power Measurements section). -
Page 30: Measuring Power
6. Connect the output connector of the measurement jumper to the detector adapter. This end of the measurement jumper is user-selected and must be compatible with the input connector of the DUT. 7. Press the Power key to set the meter to Power mode. When in Power mode, the meter displays P at the beginning of the reading, and no “rel”... -
Page 31: Measuring Relative Power (Insertion Loss)
5. If a measurement is to be made at a second wavelength, repeat steps 2 to 4. Figure 12: Measuring Absolute Power Measuring Relative Power (Insertion Loss) The value for relative power is the negative value of the insertion loss, for example -31 dB instead of 31 dB. -
Page 32: Power Accuracy
Figure 13: Measuring Relative Power Power Accuracy The absolute accuracy of power measurements made with the Backreflection Meter is dependent on the power level to be measured. The Backreflection Meter does not measure power levels below -50 dBm unless the dark signal from extraneous sources ( ) is stored. -
Page 33: Messages And Symbols
Messages and Symbols The messages and symbols displayed by the Backreflection Meter are described in Table 7. Table 7: Backreflection Meter Display Messages and Symbols Display Description Displayed momentarily during the power-up sequence and indicates RMXXXXB VERY.Y the model number (XXXX) and the software version (Y.Y). Displayed momentarily during the power-up sequence as the initial STABILIZING internal reference measurements are made. -
Page 34: Calibrating The Meter
Devices with malfunctioning lasers must be returned to the manufacturer for calibration. Annual calibration of the meter by JDS Uniphase is recommended. This section outlines how to do periodic adjustments to ensure the accuracy of backreflection, loss, and power measurements. Use only the calibrated jumper for all calibration procedures. -
Page 35: Power Calibration Adjustment
1. Repeat the calibration adjustment procedure for the second wavelength. Power Calibration Adjustment To perform a power calibration adjustment: 1. Press the Power key to set the Backreflection Meter to Power mode. In Power mode, the meter displays P at the beginning of the reading, and the value displayed is not followed by “rel”. -
Page 36: Cleaning The Connector Ends
The Backreflection Meter can be used while it is recharging. Replacement of Internal Fuses The following fuses can be replaced by JDS Uniphase qualified technicians only: 1. Fuse F1 on battery protection circuit PCB, 250V, F2A. 2. Fuse on battery cord, 250V, F1.6/10V... -
Page 37: Troubleshooting
Troubleshooting If any problem described in this section persists, contact JDS Uniphase or your local representative. Every backreflection measurement is affected by the loss before the DUT and by reflections before and after the DUT. • Loss Before the DUT When a DUT is connected to the Backreflection Meter, the loss from connectors before the DUT affects the backreflection reading. - Page 38 • Laser Stability If the messages “Source Unstable” or “Input Low” are displayed, remove the front connector panel, clean the front panel connectors, connect the internal FC/APC connector to the detector adapter, and press the Power key to set the meter to Power mode. The reading must be steady and higher than -10 dBm.

Page 40: Programming Guide
Programming Guide RS232 Serial Interface The Backreflection Meter is equipped with an RS232 serial interface. Through the RS232 connection, the user can download measured values of backreflection, loss, and power to a computer or printer. The Backreflection Meter can also use an IEEE 488 parallel interface through the external RS232-to-IEEE 488 converter (described in the RS232-GPIB Converter section). - Page 41 On power-up, the RTS and DTR signals on the interface connector go positive, indicating that the interface is ready to communicate. The software on the controlling computer must enable the RTS line. The interface controller waits for the CTS line to go positive before the measurements are transmitted.

Page 42: Rs232-Gpib Converter
RS232-GPIB Converter An optional user-supplied RS232-to-IEEE 488 converter can be used with the RS232 connector on the Backreflection Meter to access an IEEE 488 parallel interface. The converter, supplied with the appropriate RS232 cable, is attached to the RS232 connector on the rear panel. The converter is set up and tested as described in Table 10 and Table 11. -
