OPM, kalibrasi dan pengukuran redaman total kabel fiber optik

Summary

This tutorial demonstrates the process of calibrating an optical power meter and measuring the total attenuation of an optical fiber cable. It begins by setting up the equipment, including cleaning and connecting the optical fiber, followed by calibrating the power meter at a wavelength of 1310 nm. The process then covers how to measure the power received, calculate total fiber attenuation, and apply the standard formula for attenuation calculation. The video also emphasizes the importance of maintaining the equipment properly after use to ensure optimal performance and longevity.

Takeaways

• 😀 The tutorial focuses on calibrating an optical power meter to measure the total loss of optical fiber cables.
• 😀 The calibration process involves ensuring the correct wavelength (1310 nm) is selected on both the optical source and the power meter.
• 😀 Two optical vectors are used to perform the calibration: one connected to the optical source and the other at the far end of the fiber cable.
• 😀 The optical power meter is set to read power levels in dBm, with a power output of -7.69 dBm during calibration.
• 😀 The power meter should display the received power after calibration, which is measured at -7.69 dBm.
• 😀 The fiber optic cable's total loss is calculated by comparing the power received at the meter with the calibrated power level.
• 😀 The loss is calculated using the formula: total loss = calibrated power - received power.
• 😀 In this case, the power loss of the optical fiber cable is determined to be 0.70 dB.
• 😀 The procedure also emphasizes the importance of cleaning the connectors before calibration using a one-click cleaner.
• 😀 After measurements, the equipment must be properly cleaned and stored to maintain its functionality and longevity.

Q & A

What is the purpose of the calibration process described in the video?

The calibration process is used to measure the optical power received by the optical power meter and to ensure accurate measurement for the total attenuation of optical fiber cables.

Why are two vectors used in the calibration process?

Two vectors are used to ensure one vector connects to the optical power source, while the other connects to the fiber cable's other end. This setup is necessary for measuring the total attenuation accurately.

What is the importance of using the correct wavelength during calibration?

The wavelength must be consistent between the optical power meter and the optical power source to ensure accurate power measurements and reliable results.

What is the significance of the value '-7.69 dBm' in the script?

The value '-7.69 dBm' represents the calibrated optical power received by the optical power meter from the source. This value is crucial for calculating the total attenuation.

What does the value '-8.39 dBm' represent in the measurement process?

The value '-8.39 dBm' is the optical power measured after the optical power meter is connected to the fiber cable, indicating the power received after it has passed through the cable.

How is the total attenuation of the fiber optic cable calculated?

The total attenuation is calculated by subtracting the measured power at the end of the fiber from the calibrated power at the source. The formula used is: Power at the source (calibrated) - Measured power = Total attenuation.

What is the result of the total attenuation calculation in the script?

The total attenuation calculated in the script is 0.70 dB, which indicates the amount of optical signal loss that occurred as the light traveled through the fiber optic cable.

What precaution is mentioned after completing the measurement process?

After completing the measurement, it is important to clean up and return all equipment to its proper state. This includes reattaching the protective covers and ensuring that the tools and connectors are stored safely to maintain their functionality.

Why is it necessary to ensure proper care of the connectors and tools?

Proper care of the connectors and tools is essential to prevent damage, ensure longevity, and maintain the equipment in good working condition for future use.

What is the role of the 'One-Click Cleaner' mentioned in the process?

The 'One-Click Cleaner' is used to clean the fiber optic connectors to ensure a clean and reliable connection, which is essential for accurate calibration and measurement of optical power.
