Keysight (Agilent) 81651A 1550 nm Fabry Perot Laser Source Module

The Agilent 81651A Standard Source Module (Fabry-Perot Laser) is insensitive to back reflections, and is stabilized for short and long term applications. It is for use with Agilent 8163A/B Lightwave Multimeter, Agilent 8164A/B Lightwave Measurement System, and Agilent 8166A/B Lightwave Multichannel System. Specifications. Center Wavelength: 1550 nm ±15 nm. Fiber type: Single-mode 9/125 µm. Spectral bandwidth (rms): < 4.5 nm. Output Power: >0 dBm. Short term (15 min) CW power stability: <±0.005 dB typically <±0.003 dB with coherence control active. Long term (24 hr) CW power stability: typically <±0.03 dB. To back reflection (RL >=14 dB): Typical ± 0.003 dB. Internal digital modulation mode: 270 Hz, 330 Hz, 1 kHz, 2 kHz and free selection 200 Hz to 10 kHz. All output signals are pulse shaped, duty cycle 50%. Internal coherence control for linewidth broadening.

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.
