1.
Overview
DWDM system can transmit various
signal up to 16 channels as SDH, SONET and Low speed broadbank signal
and extend the distance by means of EDFA, compared with existing
TDM(Time Division Multiplexing) system. This system provides the
various network application of poing-to-point, ring and WAD(wavelength
add-drop) ect,.
