Page 101: 12 Typical Applications
12 Typical Applications For accurate, significant, and repeatable power measurements, it is important to consider the following points: Connectors, fiber ends, ports, and detectors should be clean at all times. A null measurement should be performed prior to each user session or whenever there is a significant change in ambient temperature or environmental conditions.
Page 102: Performing Absolute Power Measurements
Typical Applications Performing Absolute Power Measurements Performing Absolute Power Measurements Absolute power measurements are necessary when performing system or component monitoring, quality control, system or component acceptance, and troubleshooting. To carry out absolute power measurements: 1. Perform an offset nulling as explained in Nulling Offsets on page 38. 2.
Page 103 Typical Applications Performing Absolute Power Measurements Note: The high-speed power meter virtual channel (IQS-1620 or IQS-1640) is an excellent tool for comparing two optical channels. For example, if two devices (connected to channels 1 and 2) are supposed to have identical power levels, displaying a virtual channel (defined as channel 1 minus channel 2) provides easy monitoring of both devices and will quickly highlight any power fluctuations.
Page 104: Measuring Insertion Loss
Measuring Insertion Loss Measuring Insertion Loss To accurately measure the insertion loss of a fiber-optic component, use a light source (such as EXFO’s IQS-2100 Light Source) and your high-speed power meter. To measure the insertion loss: 1. Perform an offset nulling of the detector(s) if needed.
Page 105 Typical Applications Measuring Insertion Loss MPORTANT The absolute power output value is not particularly important when measuring insertion loss. It is very important, however, that the power level used for taking the reference measurement is identical to the power level used during the insertion loss measurement. 6.
Page 106: Testing Instrument Linearity
When verifying instrument linearity, a linear variable attenuator (such as EXFO’s IQS-3100 Variable Attenuator) is also required. Before verifying the linearity of an optical detector, you must confirm the linearity of the attenuator being used.
Page 107 Typical Applications Testing Instrument Linearity To confirm the linearity of the attenuator being used, you need a stable source (IQS-2100), a variable attenuator, your high-speed power meter, two test jumpers, and appropriate connector adapters. Once you are confident with both the test setup and instruments being used, you can start testing for component linearity.
Page 108: Characterizing An Optical Switch
Typical Applications Characterizing an Optical Switch 6. At this time, both the attenuator and power meter will display “0.0 dB”. Increase the attenuation using constant step sizes, while recording the values from both displays (attenuator and power meter) at each step. Continue until the power meter indicates around −55 dB.
Page 109 Typical Applications Characterizing an Optical Switch Testing Repeatability The procedure to test the repeatability of an optical switch is relatively simple. First, a reference measurement must be taken on each channel. Next, repetitive transitions of the switch must be performed. The switch repeatability will be the total deviation from the reference points.
Page 110 Typical Applications Characterizing an Optical Switch 7. Set the switch to the first position and take a reference measurement on the channel receiving the signal. 8. Set the switch to the second position and take a reference measurement on the second channel, now receiving the signal. 9.
