QIIRUN Optical Power Meter - Fiber Light Tester For 6 Wavelengths, 68g Portable Design

Network technicians and fiber optic professionals, this QIIRUN Optical Power Meter is seriously impressive for such a compact tool! Weighing only 68 grams and measuring just 120x33x30mm, this little device is incredibly portable yet packed with professional features. It tests six calibrated wavelengths - 850nm, 1300nm, 1310nm, 1490nm, 1550nm, and 1625nm - with high measuring precision across the 800-1700nm working range. The display range of -70dBm to +10dBm @1550nm covers most testing scenarios you'll encounter in the field. The universal 2.5mm interface supports FC, SC, and ST connectors, which means you can use it with pretty much any fiber optic equipment without needing adapters. What's really cool is the low power consumption - it runs on just 2 AAA batteries (not included due to shipping restrictions) and can work continuously for more than 80 hours, which is fantastic for extended fieldwork. The display shows both linear optical power and logarithmic power, plus it has automatic measuring range adjustment and power remaining indication so you always know how much battery life you have left. The relative value measurement function is super handy for comparing signal strengths or measuring loss. This meter is perfect for maintenance and testing of telecommunication lines, FTTx installations, network troubleshooting, or any situation where you need accurate optical power measurements. It comes with a carry case and user manual, making it easy to transport and use right out of the box. QIIRUN stands behind their product with a 30-day return policy and lifetime technical support, which gives you peace of mind with your purchase. Whether you're a seasoned network engineer or just getting into fiber optics, this power meter delivers professional-grade performance in a package that's light enough to carry in your pocket all day without even noticing it's there. For the features and quality you get, it's an incredible value that makes fiber testing so much more convenient!
