Low polarization-dependent optical sensor (Q82232): 0.003 dBp-p or lower

The high-sensitivity Q82232 optical sensor has a polarization dependence as low as 0.003 dBp-p.

Used in conjunction with the Q8163 polarization scrambler, it can be used for high-speed, high-precision PDL measurements of optical devices.

Low Reflection, High Return Loss Sensors

Adapters with Minimal Reflection

If the input light is reflected back, the effect on the system can lead to inaccurate measurements.

the Q82208 optical sensors use optical fibers with beveled polished ends to suppress reflections (return loss of 50 dB or more). 

the Q82208 is designed for use in optical devices with high speed and high accuracy PDL measurements.

the Q82208 is designed for use in optical devices with high speed and high accuracy.

When using PC-polished connectors, 45 dB or more return loss can be obtained by using a low-loss,

high-return-loss adapter (typical return loss without this adapter is 14 dB).

The sensor is suitable for fibers with core diameters of 10 μm and NA values of 0.19 or less,

making it suitable for measuring dispersion-shifted fibers. FC, SC, ST, MU, LC, and plug-in connectors are

available.
