DWDM（Dense Wavelength Division Multiplexing）
DWDM
DWDM（DenseWavelengthDivisionMultiplexing）is a Technology That Puts Data Different Sources Together on an Optical Fiber,with Each Signal Carried at the Same Time on Its Own Separate Light Wavelength
Features:
Low insertion loss, low PDL
High Isolation
Compact Design
Good channel-to-channel uniformity
High Reliability and Stability
Application:
Channel Add/Drop
DWDM Network
Wavelength Routing
CATV Fiber Optical System
