Keysight (Agilent) 8168E 1475 to 1575 nm Tunable Laser Source

The HP 8168E tunable laser source is a basic tool for characterizing and testing optical amplifiers and components. The current values of wavelength and output power are indicated on a large and bright display. You can select both parameters independently within the specified range. If you change the output power, the wavelength remains stable, and if you change the wavelength, the output power remains stable. Just input a new wavelength and the instrument will set it immediately. With its coherence control mode made active, the HP 8168E will feature an effective linewidth of up to 500 MHz, thus drastically reducing the interference ripple. The internal modulation frequency is selectable between 250 Hz to 300 kHz for squarewave signals with 100% modulation depth (on/off). In the external modulation mode, the bandwidth is between 200 kHz and 20 MHz with a duty cycle depending on the input signal and a maximum modulation depth of ±15%. Specifications.

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
