Introducing the IQ-3100/IQ-3300

Variable Attenuator/Variable Reflector

IQ-3100 Variable Attenuator

Variable Attenuator Typical Applications

Applications for the IQ-3100 Variable Attenuator include the following:

➤

Accurate variable output power levels over a large dynamic range
when used with an optical source (e.g., IQ-2100)

➤

Power meter calibration and linearity verification

➤

Fiber-optic system or component testing and acceptance such as
erbium-doped fiber amplifier (EDFA) characterization

➤

Simulation of fiber-optic system loss

➤

Optical margin analysis

➤

Spectral tuning
