   YOKOGAWA AQ7270-735021   Description / Specification:    
YOKOGAWA AQ7270-735021 1650 nm, 30dB Handheld OTDR

The Yokogawa AQ7270-735021 1650nm, 30dB Handheld OTDR automatically sets the optimal measurement conditions, performs measurement, performs event analysis, and saves data. Because you can save to a different file name each time you execute, measurement and accumulation of data is easy. In Multi Wavelength Measurement mode, multiple specified wavelengths from the same optical port are measured automatically in order. You can also specify to perform analysis or file saving as needed for each measurement. Specifications. Wavelength: 1650 ±5 nm (At a point -20 dB from the pulse light output peak value). Applicable fiber: SM (ITU-T G.652). Distance range: 500m, 1km, 2km, 5km, 10km, 20km, 50km, 100km, 200km, 300km, 400km. Pulse width: 3ns, 10ns, 20ns, 50ns, 100ns, 200ns, 500ns, 1us, 2us, 5us, 10us, 20us. Dynamic range: 30 dB. Event dead zone: 0.8 m. Attenuation dead zone: 12 m (typ).

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

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
