GREENLEE 920XC-20M 850 / 1300 nm Handheld OTDR

The Greenlee 920XC-20M 850 / 1300 nm handheld OTDRs can make an assessment of one single optical fiber or a whole optical fiber chain. In addition, the user can directly observe loss and events distribution of an optical fiber chain. The 20XC-20M tools check the transmission quality of optical fiber through the measurement of backscatter. Standard organizations like the International Telecom Union (ITU) define backscatter as an effective analysis means to measure optical fiber loss. Backscattering is also the only effective way of connector inspection, which can be applied to measure the length of optical fiber. The 920XC-20M OTDRs operate by reviewing events in optical fiber (for example, irregularities and connectors). These tools can help identify irregularities in optical fiber, locate them, and measure their attenuation, relevant loss, and homogeneity. These tools are easy-to-use, small, and compact with large LCD displays and graphical interfaces. They can save and transfer the measurement curves data to a PC by using the provided Trace Viewer software for further analyzing, reporting, and printing. Specifications.

Standard Calibration $350.00 *
*This is a Web introductory price for one calibration of the GREENLEE 920XC-20M. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

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.
