The long-term variations of the significant instants of a digital signal from their ideal
position in time (where long-term implies that these variations are of frequency less than
10 Hz).
A washer is a thin flat ring of metal or rubber which is placed over a bolt before the nut
is screwed on.
A technology that utilizes the characteristics of broad bandwidth and low attenuation of
single mode optical fiber, uses multiple wavelengths as carriers, and allows multiple
channels to transmit simultaneously in a single fiber.
Data for describing the wavelength protection structure. Its function is similar to that of
the protection subnet for SDH NEs. The wavelength path protection can work only with
the correct configuration of the wavelength protection group.
