RM3 SERIES BACKREFLECTION METER

USER’S MANUAL

General Information and Specifications

General Information

This user’s manual for the RM3 Series Backreflection Meter contains complete operating instructions. The RM 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). The inspection report and a description of any customer-requested information are found in Customized Features and Test Data section.

The RM meter (Figure 1) is a portable, direct-display instrument that measures backreflection, loss, and power of single-mode and multimode fiberoptic connectors, components, and systems. The RM meter is supplied with one or two internal laser sources for operation at 850, 980,1310, 1480, 1550, 1625, or 1650 nm (not all combinations are available).

Figure 1: RM Meter

An important feature of the RM meter is the FC/APC ultra-low backreflection connector at its output port (SC/APC connector also offered). By switching hybrid jumpers connected to the FC/APC connector, the user can select the connector type required for a measurement quickly and easily, without limiting the backreflection range of the meter. The RM meter is supplied with a hybrid measurement jumper to be used exclusively for measurements and a hybrid calibrated jumper to be used exclusively for calibrations.

The RM meter can be operated using an internal 6 V DC rechargeable battery.

The RM meter includes a convenient foot pedal, enabling the user to trigger the meter to send measurement data to a computer or printer.

The RM meter operates over the RS232 serial interface. Wherever the IEEE 488 GPIB parallel interface is mentioned, it is achieved via a RS232-to-GPIB converter that can be purchased as an accessory.
