SVP21 Series All-in-One Optical Power Meter (OPM) + Visual Fault Locator (VFL)

Measure. Locate. Diagnose — All in One Compact Tool.

The SVP21 Series is a multifunctional, handheld fiber optic tester that integrates four essential tools into a single rugged device: Optical Power Meter (OPM), Visual Fault Locator (VFL), Network Cable Sequencer, and Light. It is built for professionals who need high precision, portability, and speed in one package — whether for fiber network installation, maintenance, or troubleshooting.

With a wide dynamic power measurement range (up to -70~+26 dBm depending on model) and support for 850 to 1625nm wavelengths, it covers almost all standard telecom, CATV, and LAN applications. Additional features like RJ45 cable testing, wavelength memory, user zeroing, Type-C charging, and super-bright LED backlighting make this device ideal for both field and lab work.
