NOYAFA NF-919 3-in-1 Optical Fiber Tester

NOYAFA NF-919 3-in-1 Optical Fiber Tester

The NOYAFA NF-919 Optical Fiber Tester integrates an Optical Power Meter (OPM), Laser Light Source, and Visual Fault Locator (VFL) into one compact field testing device. It is designed for fiber optic installation, commissioning, maintenance, optical loss testing, and troubleshooting.

Optical Power Meter

The integrated Optical Power Meter (OPM) allows technicians to check important optical parameters including optical power, wavelength, frequency, loss, and fiber link data. The NF-919 provides testing accuracy with an error of less than 0.3 dB, supporting reliable fiber network measurements.

Laser Light Source

The built-in Laser Light Source provides stable optical signal emission for fiber link testing and total loss measurement. It can be used with the Optical Power Meter to evaluate fiber link loss and help identify transmission issues.

20mW Visual Fault Locator

The NF-919 features a 650nm Visual Fault Locator (VFL) with 20mW output power and a visual fault detection range of up to 20km, depending on fiber conditions.

The high-output VFL helps technicians identify visible fiber faults such as:

• Fiber breaks
• Excessive bends
• Damaged fiber sections
• Poor connections
• Fault locations along the fiber path

FC, SC & ST Interface Support

The NF-919 supports three commonly used fiber optic connector interfaces:

• FC
• SC
• ST

Protective caps help reduce dust and contamination on the fiber interfaces, supporting reliable testing and maintaining connector cleanliness.
