    1.1 Product Overview Chapter 1 Overview 1.1 Product Overview The 3661-20 OPTICAL POWER METER is an optical power measuring instrument for optical fiber cables. The meter has two measurement modes: optical-power measurement mode and optical-loss measurement mode. In optical-loss measurement mode, the meter calculates optical loss by using the measurement and the reference value stored in the memory.

  • Page 16: Features

    1.2 Features 1.2 Features Two Measurement Modes (Optical power measurement mode) Measures the optical power of the cable con- nected to the meter. (Optical loss measurement mode) Stores a reference measurement in advance, then takes a measurement and calculates optical loss from the measurement and the reference.
