Page 41 Selecting a Wavelength and a Fine-Tuning Step The attenuator wavelength must be set as closely as possible to the wavelength of the optical source. The IQS-3150 Variable Attenuator module provides a wide range of wavelengths: 1250 nm to 1650 nm for singlemode modules and 700 nm to 1350 nm for multimode modules.
Page 42 Although EXFO guarantees that the minimum insertion loss is below a specified value (refer to specification sheet), it may vary slightly from one wavelength to another and from one IQS-3150 Variable Attenuator to another. To change the attenuation or output-power level: 1.
Page 43 Note: The offset values must be between -99.999 dB and 99.999 dB. The attenuation value is positive; therefore, when the offset value is positive, the displayed attenuation increases.

To ensure maximum power and to avoid erroneous readings: Always inspect fiber ends and make sure that they are clean as  explained below before inserting them into the port. EXFO is not responsible for damage or errors caused by bad fiber cleaning or handling.
Page 57 EXFO uses good quality connectors in compliance with EIA-455-21A standards. To keep connectors clean and in good condition, EXFO strongly recommends inspecting them with a fiber inspection probe before connecting them. Failure to do so will result in permanent damage to the connectors and degradation in measurements.

Page 76: Measuring Multimode Insertion Loss
Measuring Multimode Insertion Loss Often, when using a multimode source (mostly LED sources), part of the optical energy is transmitted into the fiber cladding. These cladding modes attenuate rapidly, but will affect power meter readings if the source is connected using only a short jumper, as would be the case when taking a reference before measuring insertion loss.
