Fiber Optic Series: Understanding dB and dBm values
Fiber Optic Series: Understanding dB and dBm When conducting tests on fiber optic networks, the results are typically presented on a meter readout in dB. In this
Read MoreHome / Fiber optic communication unit dBm
A measurement of 0 dBm using an optical power meter indicates 1 milliWatt of power. This document focuses on decibels (dB), decibels per milliwatt (dBm), attenuation and measurements, and provides an introduction to optical fibers. Instead, it quantifies how much a signal has increased or decreased relative to another signal.
