What is an optical fiber power meter?
as a hand or table device detects the average power of the continuous light beam in the optical fiber network. Like the multimeter, the voltage or current, the fiber-optical power meter tests the signaling force of the laser or light emitting diode (LEDs) sources. Light scattering can occur at many points in the network due to disorders or non -mosses; This power meter analyzes high -performance rays of single -length fibers and low -energy multi -term multimod fibers. The unit is usually made of fixed state detector with signal conditioning electronics, digital readings and adapters for connecting to another device. The complexity of the network design, which adheres to international optical specifications standards, requires that power meters involve a certain degree of measurement uncertainty.Analysis rather than peak performance to monitor the working cycle of continuously pulsating light flows.
with a higher resolution serve meters of the table type afterCounters in the laboratory environment for testing, production and research and development. Handheld Power Metters use field optical fiber techniques in telecommunications and data networks. These devices are calibrated to measure optical force in Milliwatts (MW), microwatts (µm) or decibels referred to one Milliwatt (DBM).
Multimod optical applications usually have wavelengths at 850 nanometers (Nm) and 1,300 Nm of electromagnetic spectrum. Use with one mode is often at 1310 nm and 1,0550 nm. For these four wavelengths, it can work for both modes in a wide range of network conditions for field use for field use for field use.
Optical detectors convert light into voltage for electronic wavelengths, as well as a dynamic range or efficient light range. Silicon detectors feel light directly for short wavelength systems at 350nm to 1100 nm. Indium gallium arsenid (IngaAS) detectors suit long wavelength systems at 850 nm to 1650 nm, as well as Germania detectors at 750 nm to 1,800 nm.
The fiber power meter can also be mounted on the stand or can be connected to a computer for a direct signal analysis. General Accounting Bus (GPIB) is one typical serial bus used to connect a test device with control devices; For greater distances and transmission speeds, the RS232 and RS422 serial interfaces provide increased digital transmission. Another interface is the logic of transistor-transtator (TTL), a digital circuit that derives the output of dual transistors. Hand units can be physically and ergonomically designed for improved versatility in field conditions, with interchangeable adapters and large memory capacities. A long -term batteries or electricity can run.
