The FPM-8220 Fiber Optic Power Meter combines accurate, repeatable power measurements with low polarization dependence in a simple easy to use instrument for R&D or manufacturing testing of fiber optic components and systems. Interchangeable fiber optic power measurements heads deliver repeatable results for measurements up to +30 dBm over a wavelength range of 800 nm to 1650 nm. The FMH-8715 and FMH-87107 fiber optic power measurement heads use integrating sphere technology to virtually eliminate sensitivity to laser polarization state or fiber orientation. The FMH-8705 detector provides easy to use measurements with wide dynamic measurement range from -85 dBm to +1.5 dBm. Connectorized, bare fiber, and ferrule only measurements are possible with a variety of adapters. ILX’s patented BF-820 Bare Fiber Holder provides easy fiber positioning for repeatable bare fiber measurements. Designed for automated systems, the FPM-8220 combines precision measurement with USB 2.0 and GPIB IEEE488.2 computer interfaces. Features +2.5% accuracy <+0.01 dB repeatability +0.006 dB polarization dependent response Wavelength range of 800 nm to 1650 nm USB and GPIB remote interfaces Remote commands compatible with ILX FPM-8210 and Agilent 8163B User upgradable firmware
