Exfo FPM-300 power meter
(Power Meter FPM-300)
What is a power meter?

First, we will get acquainted with the basic explanations about what a power meter is, then we will express the technical information about the Xfo FPM-300 power meter product. A power meter or OPM, which is an abbreviation of Optical power meter, is a device that measures the power of optical signals. Power meters are generally used to measure average power in optical fiber systems. Power meters are used to calculate power, energy, active power, and reactive power, RF. and voltage and current measurements are also used. Among other tools for measuring light power, we can refer to radiometers, photometers, laser power meters (it means photodiode sensors or thermal sensor lasers) and light meters or lux meters.

Components of Power Meter: Power meter

A power meter consists of a calibrated sensor and measuring amplifier and a display.

Calibrated sensor:

The sensor used in power meters consists primarily of a photodiode to determine the appropriate range of the selected wavelength and determine the selected power level.

The display screen used in power meters is used to display the measured optical power and the set wavelength. All power meters can follow calibration standards such as the NIST global standard. You can read more information about how the power meter and light source work in the article “What is a power meter” written and edited by the Fiber Optic Bank.

Description about FPM-300 Xfo power meter

Currently, Xfo FPM-300 power meter is the most complete and at the same time the simplest power meter with high power option and ten calibrated wavelengths available, which is combined with FLS 300 or FOT 300 source unit that can be used with a digital encrypted protocol. By detecting the wavelength to be transmitted, Xfo FPM-300 power meter automatically uses the appropriate parameters for calibration, and this feature of automatic wavelength detection reduces the need to communicate between two technicians and reduces the possibility of error.

Dual reference capability for EXFO FPM-300 power meter

As mentioned above, signal encoding has the ability to provide the receiver with the final information regarding the power used as a reference, and this helps ensure efficient reference even if the two units are far apart.

A solution for FTTX

Power meter EXFO FPM 300 is one of the products of Exfo series of optical test products for FFTX technology. This test has the possibility of testing passive optical networks (PON) in three main wavelengths (1310, 1490 and 1550 nm) in fiber to the home (FTTH) networks. ) and fiber to the premises (FTTP) are used. Compliant with ITU-T G.983 and G.984 series recommendations and IEEE 802.3ah standard

No offset nulling

Thanks to the unique design, the FPM-300 power meter reduces measurement time in normal measurement conditions, as the need for drop neutralization is eliminated.
