Keysight (Agilent) N4375B 20/26.5 GHz Single-Mode Lightwave Component Analyzer

The Agilent N4375B Lightwave Component Analyzer (LCA) tests 10G Ethernet, FCx8, FCx10 and FCx16 electro-optical components, with up to 20 or 26.5 GHz modulation range. It comes in two basic versions. The economic line is based on a PNA-L network-analyzer and is available as a 2 port system. The high end version is based on the new PNA-X and offers true balanced measurements, extended optical modulation index (OMI) and is available with 2 or 4 ports. Both versions have the same specifications up to 20 GHz. The PNA-X based LCA is calibrated up to 26.5 GHz.

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
