High Sensitivity Sensors

Noise level: -94 dBm.

The Q82208 and Q82232 optical sensors achieve high sensitivity by cooling the InGaAs photodiode.

the Q82208. in particular, achieves -94 dBm. all three types are capable of measuring high power up to

+10 dBm with high linearity.

These sensors meet a wide range of user requirements for polarization correlation, return loss, and sensor

type.

They meet a wide range of measurement requirements.

High Power Input Optical Sensors (Q82227)

Maximum input power: +27 dBmThe Q82227 is suitable for long wavelength, high sensitivity and high

power light.

The sensor is capable of measuring optical inputs up to +27 dBm.

Therefore, it is suitable for measuring the output of fiber-optic amplifiers, pump sources for fiber-optic

amplifiers,and high-output devices (e.g., LDs for optical CATV).

In addition, the Q82227 has a noise level of -80 dBm, so it can be used for measurements requiring a

wide dynamic range.
