What is the acceptable light attenuation level for an optical power meter

What is the acceptable light attenuation level for an optical power meter

While most power meters have ranges of +3 to –50 dBm, most sources are in the range of 0 to –10 dBm for lasers and –10 to –20 dBm for LEDs. Monitoring the light level is a fundamental practice in fiber network engineering to ensure the signal remains strong enough for reliable detection. While optical power meters are the primary power measurement instrument, optical loss test sets (OLTSs) and optical time domain reflectometers (OTDRs) also measure power in testing loss. The maximum length of a fiber optic cable is limited by the transmitter's output power and the receiver's sensitivity. This level of testing consists of link attenuation testing, link length, and a pola ity check.
