The Xtera/Meriton Networks 7200 40-Channel DWDM MUX Card aggregates 40 optical signals onto a single fiber using Dense Wavelength Division Multiplexing with 100 GHz channel spacing. This passive card transports optical signals from 100 Mb/s to 40 Gb/s across ITU-T C-band channels 21-60, supporting multiple modulation formats including PM-QPSK and PM-16QAM. It delivers integrated wavelength switching and Carrier Ethernet transport, bridging metro access and metro core networks while replacing traditional Optical Add/Drop Multiplexers (OADMs).
