Practical Implementation of Optical Power Meter (OPM VFL 50)

Introduction

This knowledge base provides a step-by-step guide on the practical implementation of the Optical Power Meter (OPM VFL 50). This device integrates OPM, Visual Fault Locator (VFL), and RJ45 cable color grading functions, making it a versatile tool for fiber optic and networking applications.

 Practical Implementation of OPM VFL 50

ü  Powering On the Device

ü Press the power button to turn on the OPM VFL 50.

ü Ensure the display is clear and functional.

ü Select the appropriate mode (OPM, VFL, or RJ45 color grading check).

Ø Using the Optical Power Meter (OPM) Function

 Measuring Optical Power

1.     Connect the fiber optic cable to the OPM port.

2.     Select the correct wavelength (e.g., 1310nm, 1550nm, or 1625nm).

3.     Observe the power level displayed in dBm.

4.     Compare the reading with acceptable loss levels for network performance.

5.     If power levels are too low, check for cable issues or signal loss.

Ø Using the Visual Fault Locator (VFL) Function

    Detecting Faults in Fiber Cables

1.     Connect the fiber optic cable to the VFL port.

2.     Turn on the VFL to emit a red laser light.

3.     Inspect the fiber cable for visible red light leakage.

4.     Identify breaks, bends, or misalignments in the fiber.

5.     If faults are found, mark the affected area for repairs or splicing.

Ø  Checking RJ45 Cable Color Grading

 Verifying RJ45 Cable Wiring

1.     Strip the outer sheath of the Ethernet cable carefully.

2.     Arrange the internal wires according to T568A or T568B standards.

3.     Insert the wires into the RJ45 connector in the correct order.

4.     Use the OPM VFL 50 tester function to verify correct wiring.

5.     Insert one end of the RJ45 cable into one connector and the other end into the additional connector.

6.     Observe the emitted light sequence:

§  The lights will emit turn-wise, indicating the connectivity of each wire.

§  If a light does not turn on, check for incorrect wiring or faulty connections.

7.     Ensure that the corresponding lights on both connectors turn on in sequence.

§  If any light does not match, verify the pin alignment and crimping.

8.     If miswiring is detected, reassemble and test again.

Conclusion

The Optical Power Meter (OPM VFL 50) is a multifunctional tool that simplifies fiber optic and network cable tasks. By following these steps, technicians can efficiently measure optical power, detect fiber faults, and verify RJ45 cable wiring, ensuring optimal network performance and reliability.
