When you install and terminate the fiber optic splice closure, you must always test them. Each fiber optic cable factory has three major areas of testing: continuity, loss and power. The optical power meter is part of the main point of doing the toolbox. There are general purpose power meters, semi-automatic power meters, and fiber optic power meters optimized for some types of networks, such as FTTx or LAN / WAN architectures. This is all that is needed to choose the right gear.
Optical power meters are commonly used to measure absolute optical power in dBm. For dBm measurements of optical transmit power, proper calibration is essential. Fiber optic power meters are also used with optical light sources to measure loss or relative power levels in dB. In order to calculate the power loss, the optical power meter is first directly connected to the optical transmission equipment through a fiber pigtail and measures the signal power. Then measure at the far end of the cable.
Fiber Power Meter Detects the average power of a continuous beam in a fiber network to test the signal power of a laser or light emitting diode (LED) source. Light scatter may occur at many points in the network due to failure or misplacement; the power meter analyzes the low-power multi-beam of high-power and short-range multimode fibers over long-range single-mode fibers.
Important specifications for fiber optic power meters include wavelength range, optical power range, power resolution, and power accuracy. Some devices are rack or handheld. Other designs are for use on the desktop or desktop. A power meter connected to the computer is also available. A fiber optic power meter is a special type of photometer used to measure the amount of light coming out of the end of an optical cable. Power meters need to be able to measure light at the right wavelength and in the right power range. Power meters used in most data communications networks are designed for 850nm and 1300nn. Most fiber optic power meters are calibrated in linear units, such as milliwatts or micro-watts. They can also provide decibel measurements based on milliwatt or microwatt optical power.
