There are two relevant types of architecture:
– Broadcast and Select – legacy method of using optical splitters to copy every wavelength to every degree, but at great expense of optical power and thus worse OSNR, and requiring fixed frequency ports
– Route and Select – modern, nLight method of using a full mesh patch panel interconnecting every degree to every degree, and picking which wavelengths get filtered out
(question is asking about the nLight method)
