PRODUCT INTRODUCTION
ERM-202
Polarization
Extinction Ratio Meter
The ERM-202 is a rotating-polarizer polarization extinction ratio
meter. It is available in single or dual channel versions.
MAIN SPECIFICATIONS
PRODUCT DESCRIPTION
The ERM-202 combines low noise circuitry with a high
resolution stepper motor to achieve a PER dynamic range of 50 dB and angle
resolution of 0.06°. It simultaneously measures PER, output power, and axis
angle of the DUT. In addition, the dual channel version measures the power
ratio of a device with two polarization maintaining (PM) outputs, such as a
Y-branch fiber gyro IOC, PM coupler (PMC), or polarization beam splitter (PBS).
PRODUCT SOLUTIONS
Applications of the ERM-202 include PM
fiber pigtailing of modulators, waveguides, and laser diodes, as well as PMC
and PBS manufacturing, PM fiber connectorization, depolarizer characterization,
PM fiber fusion splicing, PM fiber coil production and quality assurance for
fiber gyros.
