   ILX LIGHTWAVE FMH-8715   Description / Specification:    
ILX LIGHTWAVE FMH-8715 800 to 1650 nm InGaAs Optical Power Measurement Head

The FMH-8715 Fiber Optic Measurement Head is an integrating sphere based measurement head compatible with the FPM-8220 Fiber Optic Power Meter. The FMH-8715 is designed to measure optical power from -70 dBm to +20 dBm over a wavelength range of 800-1650nm. Interchangeable fiber optic adapters allow the FMH-8715 Fiber Optic Measurement Head to be compatible with a wide range of connectors including FC, SC, LC, bare FC ferrule, and bare fiber. Careful attention to the design allows the FMH-8715 Fiber Optic Measurement Head to achieve a polarization dependent response of less than ±0.006 dB.

dBm
Optical power referenced to 1 millimatt

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
