An integrated optical power meter and light source meter combines a fiber optic power measurement device with a calibrated light source, enabling accurate testing, troubleshooting, and certification of fiber optic networks.

Overview

Integrated optical power meters (OPMs) and light source meters (LS) are essential tools for fiber optic network installation, maintenance, and troubleshooting. These devices allow technicians to measure optical power, insertion loss, and attenuation in both singlemode and multimode fibers while simultaneously providing a stable light source for testing purposes . By combining both functions in one unit or kit, users can perform complete optical loss measurements without needing separate instruments .

Key Features

• Wavelength Support: Many integrated meters support multiple calibrated wavelengths, such as 850, 980, 1270, 1300, 1310, 1490, 1550, 1577, 1625, and 1650 nm, allowing testing across standard telecom and LAN networks .
• Multimode and Singlemode Compatibility: Devices are designed to work with both fiber types, ensuring versatility for different network environments .
• Dynamic Range: High dynamic range enables accurate measurement of weak and strong signals, critical for troubleshooting and network certification .
• Visual Fault Locator (VFL) Integration: Some models include a VFL, which emits a visible red laser to quickly locate breaks or faults in fiber cables .
• Ruggedized Design: Many units are IP54 compliant or similarly rugged, providing durability for field use .
• Accessories: Optional adapters, power supplies, carry cases, and fiber inspection probes enhance usability and ensure compliance with standards like IEC61300-3-35 .

Applications

• Insertion Loss Measurement: Determine the loss between two points in a fiber link.
• Network Troubleshooting: Identify faulty or dirty connectors, breaks, or bends in fiber cables.
• Certification and Compliance: Verify that fiber installations meet industry standards for LAN, telecom, and PON networks.
• Equipment Testing: Measure output power from optical transmitters or other network devices .

Popular Models and Kits

• Tempo Communications OPM/SLS Kits: Offer dual and triple wavelength lasers or LEDs, with ruggedized enclosures for field testing .
• OWL Optical Power Meters: Can be bundled with multimode or singlemode light sources and include precision-coupled VFLs for near-end fault detection .
• VIAVI SmartClass Fiber Kits: Pocket-sized kits combining OPM and light source for installation and maintenance, with support for PON and DOCSIS networks .
• FiberMASTER Power Meter & Light Source: Includes touchscreen tools, fiber inspection probes, and software for reporting and certification .

Conclusion

Integrated optical power meter and light source meters are versatile, all-in-one tools that simplify fiber optic testing by combining measurement and light generation in a single system. They are widely used in telecom, LAN, and PON networks for installation, troubleshooting, and certification, offering features like multi-wavelength support, VFL integration, and ruggedized designs for reliable field performance .
