OPTICALMEASURINGINSTRUMENTS
High-resolution Optical Power Measurement Optical Input Method of the Sensor specification High-speed Analog Output The MT9810B has a panel of high resolution of 1/1000 dB. In addi-
tion, the optical power can be measured at a high resolution of
1/10000 dB via GPIB or RS-232C interface. The MU931311A Optical Sensor can send a signal to an analog out-
put terminal with a response speed of approx. 10 µs (The response
speed of other optical transducers is approx. 100 µs).

MA9901A/B Fiber Adapter Setting can be accomplished without touching the cut fiber edge by
using the clamping method, which catches and then fixes the fiber at
both ends. Fiber can also be easily attached and removed by pinch-
ing the clamp, making this adapter perfect for extended work.

High-sensitivity Optical Sensor (MU931311A) The MU931311A has an optical power range of +10 to –110 dBm
and measures high-level to extremely low-level light. It achieves
measurement uncertainty of ±2% and linearity of ±0.01 dB. Optical
power can be measured with a high degree of accuracy. And of
course, this optical sensor is compatible with all manufacturers of connectors. ∗

Large Diameter PD Sensor (MA9333A) This is a sensor head-model optical sensor that has lownoise char-
acteristics,and uses an internal photo acceptance unit with a ±5
mm-InGaAs-PD.In addition to SM, GI and POF (plastic fiber), a col-
limated spatial beam can also be measured directly.This optical sen-
sor also supports bare fiber.
When using MA9333A, MU931002A Sensor Adapter is necessary.
