   YOKOGAWA AQ7270-735020   Description / Specification:    
YOKOGAWA AQ7270-735020 1550nm, 32dB Handheld OTDR

The Yokogawa AQ7270-735020 1550nm, 32dB 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: 1550 ±25 nm. 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: 32dB. Event dead zone: 0.8 m. Attenuation dead zone: 8 M (typ). Sampling resolution: 5 cm, 10 cm, 20 cm, 50 cm, 1 m, 2 m, 4 m, 8 m, 16 m, 32 m. Readout resolution: 1 cm (Min.). Number of sampled data: Up to 50,000 points. Group refractive index 1.30000 to 1.79999 (in 0.00001 steps). Unit of distance: km, kf, or miles. Distance measurement accuracy: Offset error: ±1 m Scale error: Measured distance x2 x10^-5 Sampling error: ±1 sampling resolution. Vertical axis scale: 0.2 dB/div, 0.5 dB/div, 1 dB/div, 2 dB/div, 5 dB/div, 7.5 dB/div. Readout resolution: 0.001 dB (Min.). Loss measurement accuracy: ±0.05 dB/dB. Distance measurement: Displays up to eight digits of the relative one-way distance between two arbitrary points on the trace. Loss measurement: Displays one-way loss in steps of 0.001 dB to a maximum of 5 digits; Displays the one-way loss, loss per unit length, and splice loss between any two given points on the waveform. Return loss measurement: Measures return loss and total return loss of a fiber cable or between two arbitrary points on the trace. Analysis functions: Multi trace analysis, 2 way trace analysis, differential trace analysis, section analysis. Options. /PM: Optical power monitor. /LS: Light source. /PL: Built-in printer, LAN. /DF: Dummy fiber (SMF). /SB: Shoulder belt.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence is the pattern and or relationships of waves due to phase properties.

Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. 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.
