Optical fiber power meter is a professional tool uses to measure the power of light energy contained in the optical fiber. These meters are very important since they help into making sure the fibre optic network that allows fast internet and communication is working as intended and efficiently. This means that when we say power meter, it sends a beautiful light (a light signal) energy flowing through the fiber, this is palpable into gas electrical signal. It becomes a straightforward signal to read and measure. These power meters typically display its readings in either decibels (dB) or milliwatts (mW). Measuring in lumens per meter per second allows us to quantify how much light energy is emitted in the fiber.
How To Calibrate Your Power Meter
Regular calibration, or fine adjustment, of your optical fibre power meter is essential to ensure it provides you with accurate measurements. This is where calibration comes in because it’s what makes sure that every single one of your readings is precise. Here is a simple step by step guide to ensure you get your power meter calibrated the right way and make use of it:
First attach the power meter to a stable optical source (a fixed light source). That is to say, the light source must provide a stable and consistent amount of light.
First, zero out your power meter. This is accomplished by turning the calibration knob until the display reads zero. Taking a Measurement It is crucial to measure your space as this will give you a clear starting point for where your measurements should be taken.
Then record the reading shown on the display of the light energy being transmitted through the fiber. This is your indication of the level of light within the fiber.
Now compare the reading you just got with the expected value. That means you know what the reading is supposed to be in normal circumstances. If they do not match, calibrate accordingly.
And then repeat until you are comfortable your power meter is delivering accurate readings.
Optical Fiber Power Level Measurement Tips
We have compiled some tips that may help you when measuring power levels in fiber optic power meter. Here are some crucial tips to remember:
That is good because if they are dirty or broken, there could be signal loss and you won’t get the proper measurements.
Check all the fiber connections and make sure they are tight. That way, no light can leak, which could also skew your readings.
Put the power meter inline with the fiber cable. So the meter has to be placed appropriately to catch all the light energy emerging out of the fiber.
Measure several times for the average. It gives you a better reading as opposed to just an average if you were to take a single measurement.
Regular calibration of the power meter is also required to keep it accurate. Calibrating assures that you will receive reliable and consistent results every time.
Common Power Meter Problems and How to Fix Them
Optical fiber mini power meter sometimes run into known issues that can interfere with their normal functioning. Using this knowledge, here some useful tips to diagnose and resolve these problems:
If the power meter is exhibiting abnormal undefined readings, inspect the fiber connectors for any loose or damaged components. Analogue gauges: A faulty or loose connection can cause erratic readings.
If the power meter is not registering any light energy at all, ensure that the fiber is well-aligned with the detector. If it does not line up, the meter will not measure the light.
If the power meter reads less power than you expect, clean the fiber connectors to remove dust or dirt and then recalibrate the unit. This should help you to read more accurately.
So if you feel and see that the power meter is overheating, its better to cool it before doing some measurements again. Incorrect readings can occur due to overheating.
If your power meter still has problems after doing so and fails to work properly, please contact Aitelong customer service for more help. They are able to give you the assistance you require.
The two-part series on making your optical fiber power meter work better
Here are a few tips to ensure you extract as much functionality as you can from your optical fiber power meter:
Keep the power meter away from dust and moisture. It is protected from dirt and debris, which can damage a part and affect the condition of the vehicle.
A word of caution: always treat that power meter with kid gloves. It contains delicate parts that are easily broken if shaken or mishandled.
The fiber connectors and the detector should be cleaned regularly. That maintenance is necessary to keep the transmission of the light functioning and to guarantee precise measurements.
As needed, update the power meter software. As will be able to use new features and improvements that can improve the operation of your power meter.
Consult Aitelong or check the user manual for any additional tips and troubleshooting. There is information in the manual that can help optimize the way you use your power meter.
Guide
You have this guide, you can use your optic power meter to maintain your fiber optic network efficiently. So remember to regular power meter calibration, power level measurement, problem diagnosis and troubleshooting, maximum efficiency to get the best results.
