EXFO FPM-302X Optical Power Meter

The Exfo FPM-302X Optical Power Meter automatically uses the proper calibration parameters when combined with the FLS-300 or FOT-300 source units. With a high-power option and 10 calibrated wavelengths, the FPM-302X is the most complete, yet simple power meter available. Combined with the FLS-300 or FOT-300 source units, which can transmit with a wavelength-identification digital encrypted protocol, the FPM-300 automatically uses the proper calibration parameters. This auto-wavelength recognition feature reduces the need for communication between the two technicians and decreases the potential for error. This product is part of EXFO's series of FTTx optical test products. It allows 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. Signal encrypting can also give the receiving end information on the power to be used as reference, helping ensure efficient referencing, even when the two units are far apart. Thanks to its unique design, the FPM-302X power meter reduces measurement time in typical measurement situations, as the need for an offset nulling is eliminated.Power meter port GeX.

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.
