FPMProduct Features±0.001dB typical polarization
dependent response
Measures up to +33dBm at pumpwavelengths ( <1000nm)
Single input port for bothconnectorized and bare fiber
measurements
Adapters available for mostcommon fiber optic connectors
Large measurement head forstability on the production benchCompetitive, cost-effective fiber optic component
manufacturing calls for accurate power measurementsthat can be easily repeated. For reliable comparison, theFPM-8210 and FPM-8210H Fiber Optic Power Meters havea single input port for both connectorized and bare fibermeasurements. Virtually insensitive to polarization stateor to pattern changes from fiber orientation, these meters
deliver repeatable high resolution results.
ILX Lightwave engineered the FPM-8210 and the FPM8210H for your production test workstation. The innovative
fiber optic head design makes reliable fiber endface
positioning a routine task, whether or not the fiber has aconnector.
The FPM-8210 and FPM-8210H Fiber Optic Power
Meters are the factory measurement tools to drive down
your component PDL specifications while increasing testthroughput.

Product Overview
place as the bare fiber endface, giving comparableresults.
The BF-820 Bare Fiber Holder is designed to holdand position a common telecom fiber. Inside the BF-820,
opposing V-guides facilitate correct fiber positioning.
Outside, knurled finger grips enable single-handed
maneuvering of the fiber holder.

These meters combine power measurement
accuracy with the industry’s lowest polarization
dependent response. ILX’s innovative, patented detector
cavity delivers repeatable and flexible measurementsfrom either bare or connectorized fiber.
Optimized for bare fiber measurements, theintegrating cavity detector head delivers the longest
bare fiber measurement zone, anywhere from
1–5 mm from the holder, with essentially no change inresults. Precise fiber orientation is no longer necessary
for repeatable measurements.
ILX Lightwave adapters accommodate the mostcommon fiber optic connectors. The change frombare to connectorized fiber is simple. The connector
adapters locate the fiber ferrule in exactly the same

The BF-820 Bare Fiber
Holder completely encircles
the fiber, prohibiting
ambient light frominterfering with power
measurements.
