Channels lie in the range 1530. ITU G694. The manufacture of the 100G DWDM QSFP28 transceiver is based on a highly integrated silicon photonic chip. DWDM memberikan solusi yang lebih baik dalam penggunaan serat optik yang telah terpasang untuk memperoleh keefektifan lebar pita. Tunable DWDM transceivers allow you to control the wavelength (color) that the laser channel emits, adding flexibility and reducing cost. DWDM技術とは. W kolejnych rozszerzeniach tego standardu dodano siatkę 50 GHz (96 kanałów) i następne. DWDM combines data signals from sources over a single pair of optical fibers and it maintains separation of the data streams.
