RM3 SERIES BACKREFLECTION METER

USER’S MANUAL

 

 

 

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).

 

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.
