Keysight (Agilent) 8168D 1490 to 1565 nm Tunable Laser Source

The HP 8168D 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 8168D 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.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength
Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
