EXFO ELS-500 LED / Laser Light Source

The Exfo ELS-500 Series light source are handhelds built for top ruggedness, perfect for the harshest test conditions. They feature a keypad/LCD backlight, for easy operation in darker environments, rechargeable batteries and interchangeable connectors. Exfo ELS-500 testers help you achieve first-class testing and certification of private/enterprise/premises networks. These products are part of EXFO's series of FTTx optical test products. They allow for the testing of passive optical networks (PONs) at the three main wavelengths (1310, 1490 and 1550 nm) used in fiber-to-the-home (FTTH) and fiber-to-the-premises (FTTP) networks and complies with the ITU-T G.983 and G.984 Recommendation series and the IEEE 802.3ah standard. The EXFO’s ELS-500 light source provides excellent stability and high measurement accuracy for two singlemode wavelengths (1310 or 1550 nm) on a single port, or four wavelengths (850/1300 nm and 1310/1550 nm) on two ports. It is the perfect complement to the EPM-500 Power Meter when it comes to measuring attenuation on fiber-optic links. When used with the EPM-500 Power Meter, tone generation is just a button away. The ELS-500 has the highest singlemode output power in the industry. Central wavelength (nm): 850 ± 25 / 1300 +50/-10 (ELS-500-12D), 1310 ± 20 / 1550 ± 20 (ELS-500-23BL), Spectral width (nm): 50/135 (ELS-500-12D), Output power (dBm):>= -20/>=-20 (62.5/125 µm) (ELS-500-12D), = 1/= 1 (ELS-500-23BL). Automatic wavelength switching: Yes, Tone generation: 270 Hz, 1 kHz, 2 kHz, Battery life (hours) (typical in Auto mode): 50.

*This is a Web introductory price for one calibration of the EXFO ELS-500. 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.
