Common Questions About the VeEX FX81 PON Optical Power Meter

What is the VeEX FX81 used for?
The VeEX FX81 is a PON optical power meter used for installation, service activation, and troubleshooting of GPON, XG(S)-PON, 25G PON, EPON, and 10G EPON fiber networks.

What is the difference between pass-through and terminated testing on the FX81?
In pass-through mode, the FX81 measures downstream and upstream signals simultaneously while allowing traffic to continue to an ONT or ONU. In terminated mode, it measures signals without passing traffic, which is useful for OLT verification and network validation.

Who uses the FX81 PON power meter?
The FX81 is commonly used by fiber technicians, construction crews, and service providers who need accurate multi-wavelength power measurements across multiple PON technologies.

How the FX81 Supports PON Network Installation and Verification

The VeEX FX81 PON Optical Power Meter is designed to support modern and next-generation PON deployments. With concurrent wavelength measurements, pass/fail thresholds, and support for GPON through 25G PON, it allows technicians to quickly verify signal integrity, confirm service readiness, and document results during installation and maintenance.
