   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). 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. /LS: Light source. /PL: Built-in printer, LAN. /DF: Dummy fiber (SMF). /SB: Shoulder belt.

Bandwidth
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Extinction Ratio (ER)
Extinction Ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, (example a laser diode), where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage.

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.

Wavelength Repeatability
Wavelength Repeatability is the random uncertainty in reproducing a wavelength after detuning and re-setting the wavelength. The wavelength repeatability is ± half the span between the maximum and the minimum value of all actual values of these wavelengths. Example test condition: uninterrupted TLS output power, constant power level, temperature within operating temperature range, coherence control off, short time span. Note: NOTE The long-term wavelength repeatability can be obtained by taken the wavelength repeatability and wavelength stability into account.
