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.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
