DOP-201 Product
DOP-201

Degree of Polarization Meter

The DOP-201 Degree of Polarization Meter simultaneously measures the degree of polarization (DOP) and power of a light source under test.

Product Description

The DOP-201 uses a low activation loss fiber squeezer polarization controller in conjunction with a patented maximum-minimum search method that allows it to unambiguously measure both low and high DOP values in 30 ms, and to operate over a wide wavelength range. Simultaneous measurement of DOP and optical power level of the light source under test can be used to obtain DOP power dependence and to ensure low insertion loss during depolarizer manufacturing.

Solutions and Applications

Fiber optics

The DOP-201 measures the output DOP of a light source or optical device. Applications include characterization of low and high DOP light sources, depolarizer characterization, and characterization of fiber gyro coils.
