In this application, an iConverter 4-Channel Multiplexer/Demultiplexer (CWDM/X) module is used to multiplex one T3 and three Gigabit Ethernet data channels onto one fiber common link, using example wavelengths 1470, 1490, 1590 and 1610. iConverter CWDM/AD modules are used to multiplex/demultiplex the 1470 and 1490 wavelengths from the fiber common link coming from the CWDM/X to Gigabit Ethernet switches, while the remaining wavelengths continue along the common link. At the end of the network, a third CWDM/AD is used to drop the 1590 wavelength to the Ethernet switch and the 1610 wavelength to the T3 router.
