Optical Power Meter
Optical power meters are designed to measure the power of various types of optical signals, such as visible light or infrared light, which are transmitted through optical fibers.
With 3 year warranty and affordable price.
These meters are essential for evaluating signals like data, voice, or video in applications such as telecommunications, data centers, cable television, and fiber optic sensing systems.
A photodiode or photodetector converts incoming optical power into an electrical signal, which is displayed as a power reading in dBm or mW.
Power meters are often used alongside other testing equipment like light sources and OTDRs to assess the health and performance of fiber optic networks.
They help identify signal strength, attenuation, faults, and breaks within the network.
