   EXFO EMP-502   Description / Specification:    
EXFO EMP-502 Optical Power Meter

The Exfo EPM-500 / EPM-502 power meter provides highly accurate power measurements, as well as reference value setting capabilities. What’s more, this convenient unit requires no offset nulling, for reliable, long-lasting performance in the field. Use this meter for easy tone detection and automatic wavelength recognition. This unit has a memory capacity of 1000 data items, pass/fail tresholds and LED indicators for ease of use. The Exfo EPM-500/EPM-502 can also easily transfer data to a PC via a USB connection. Like all EXFO portable instruments, FiberBasix 500 handheld units are built for top ruggedness and convenience, perfect for the harshest test conditions. They feature a keypad/LCD backlight, for easy operation in darker environments, rechargeable batteries and interchangeable connectors. Reporting Software for the Exfo EPM-500/EPM-502 Power Meter new software tool enables you to produce professional-looking reports with comprehensive documentation. It also offers these functionalities: Two test files can be merged into one test report (see note no. 3), Pass/fail thresholds that are active during download are automatically activated and displayed in the Report Viewer, One-touch storage of results for all wavelengths at once, Unit B configuration information can be input and documented, Data transfer can be launched from the Report Viewer window, A pass/fail threshold can be set for an individual fiber or wavelength.

*This is a Web introductory price for one calibration of the EXFO EMP-502. 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.
