What nm range is typically selected for optical power meters to measure optical attenuation
Most power meters are designed to operate at 850 nm and 1300 nm because these wavelengths are commonly used in fiber optic communications. We describe NIST measurement services for the calibration of optical fiber power meters. Getting this right matters a lot because if the meter isn't calibrated for the right range, its readings won't be accurate or reliable. Most meters work somewhere between 800 nm and 1700 nm. 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.

PoE switch power supply distance
In PoE (Power over Ethernet) technology, the Ethernet link between the Power Sourcing Equipment (PSE) and the Powered Device (PD) has a clearly defined maximum distance limit—100 meters (328 feet). 3bt (PoE++) are the three primary power supply specifications for PoE. This limitation is not arbitrary; it is defined by the IEEE Ethernet standards that govern PoE. The max PoE distance over Ethernet is 100 meters (328 feet) between a PoE power sourcing equipment (PSE) port and a powered device (PD). This PoE max distance is set in the IEEE 802. This limitation stems from the signal attenuation characteristics of twisted pair cables - the higher the data transmission rate, the more. PoE allows electrical power and network data to be transmitted together through a standard Ethernet cable (such as Cat5e or Cat6).
