16 Feb 2021 TEMPO’s optical wavelength splitters allow a standard powermeter (OPM) to be able to measure signal levels in WDM networks. The wavelength splitter OWS200 “splits” multiplexed wavelengths found in NGPON2 networks (Next Generation Passive Optical Networks) also known as TWDM-PON, allowing specific wavelengths to be measured with a conventional optical powermeter. Configurable for 2,4 and 8 wavelengths and has low return loss to protect network disruption.
