   Keysight (Agilent) 11980A   Description / Specification:    
Keysight (Agilent) 11980A Lightwave Fiber Optic Interferometer

The Agilent 11980A is a Mach-Zehnder interferometer of fixed delay. Used with an Agilent 71400-series lightwave signal analyzer, it allows ,you to measure chirp and frequency modulation (FM) on DFB lasers. Traditional measurements of laser Iinewidth on single-line lasers can also be made. Together, the interferometer, lightwave signal analyzer, and a gateable RF source permit the display of a true power spectrum of single-frequency lasers. This includes the display of intensity modulation linellidth and componenrs of chirp caused by the intensity modulation. Specifications. Optical Insertion Loss, 1300 nm/1550 nm: <8 dB. Wavelength Range: 1250 to 1600nm. Delay Time: 3.5 us, 25 usec with Option 005. Option 005 replaces the standard 0.76 km of delay with 5.2 km, to measure laser linewidth down to 30 kHz. Connector Interface Options. Option 011: Diamond HMS,lQ Connector. Option 012: FC/PC Connector. Option 013: DIN 47256 Connector. Option 014: ST Connector. Option 015: Biconic Connector.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
