Summary

This video tutorial provides an in-depth guide on optical fiber certification, focusing on measurement, testing, and analysis. The presenter demonstrates the use of an OTDR for fiber optic measurement, followed by fiber optic splicing, and optical power meter (OPM) testing. Viewers learn how to fill in certification forms, set equipment parameters, and interpret measurement results. The tutorial emphasizes the importance of comparing measurement data against reference values to determine the quality of fiber optic installations. Key procedures include testing fiber lengths, identifying damage, splicing, and assessing signal loss for optimal network performance.

Takeaways

• 😀 The first step in the certification process involves measurement using an OTDR (Optical Time Domain Reflectometer).
• 😀 After measurement, the next step is performing fiber optic splicing using a splice machine.
• 😀 The third step in the process is conducting measurements using an Optical Power Meter (OPM).
• 😀 The initial process involves filling out an identity form with details like name, company, testing date, and testing location.
• 😀 It is important to ensure that all equipment, such as connectors, are clean before conducting measurements for accuracy.
• 😀 The OTDR should be set to an appropriate wavelength and pulse width to achieve accurate results, with typical settings around 1310 nm and 1000 microseconds.
• 😀 When using OTDR in auto mode, the system can automatically detect faults or events along the fiber and display the location and distance of the fault.
• 😀 The results from OTDR measurements, including fiber length and event locations, need to be compared with reference values to determine the condition of the fiber.
• 😀 During fiber splicing, care must be taken to minimize splice loss, with acceptable thresholds defined for good quality splicing results.
• 😀 The Optical Power Meter (OPM) is used to measure signal loss across fiber optic connections, ensuring that the system performs within the specified limits.
• 😀 After all measurements are taken, the results must be carefully recorded and analyzed to determine if the fiber system is in good or poor condition based on pre-set standards.

Q & A

What is the main focus of the video script?

The main focus of the video is to demonstrate the steps of performing certification measurements and fiber optic cable testing using different equipment such as OTDR, Optical Power Meter, and connectors for fiber optic splicing.

What is the first step in the certification process described in the script?

The first step in the certification process is to conduct measurements using an OTDR (Optical Time Domain Reflectometer).

How does the process of fiber optic splicing begin?

The process of fiber optic splicing begins with preparing and cleaning the fiber connectors using a fiber cleaner before connecting them using a fusion splicer or a similar tool.

What settings are adjusted on the OTDR during measurements?

The settings adjusted on the OTDR include the wavelength (e.g., 1310nm), the distance (set to 1 km for this demonstration), pulse width, and other parameters like index of refraction and threshold values for acceptable losses.

How is the fiber optic splicing quality assessed in the video?

The quality of fiber optic splicing is assessed by measuring the insertion loss and comparing it with reference values. If the loss exceeds the reference threshold, the splice is considered poor.

What does the video demonstrate about optical power meter (OPM) measurements?

The video demonstrates how to use an Optical Power Meter (OPM) to measure the optical signal power at specific wavelengths (like 1310nm) and record the results for further analysis and comparison.

What is the importance of cleaning connectors before measurement?

Cleaning connectors before measurement is crucial to ensure accurate results, as dirt and contaminants on the fiber ends can significantly affect the measurement accuracy and lead to false readings.

What happens if the OTDR measurement shows a high loss value?

If the OTDR measurement shows a high loss value, it indicates potential issues such as poor splicing, excessive fiber bending, or other defects in the fiber optic network, suggesting that the network needs further inspection or repair.

How is the performance of a fiber optic link evaluated based on the measurements?

The performance of a fiber optic link is evaluated by comparing the measured losses (insertion and splice losses) with standard reference values. If the measured losses are within acceptable limits, the link is considered good. If the losses exceed the standards, the link is deemed faulty.

What role does the assessor play in the certification process?

The assessor's role is to guide the process by providing the fiber cable details to be tested, confirming the test parameters, and evaluating the results to ensure the network meets the required standards for certification.
