Specifications
Due to the physical nature of light, the signals on WDM wavelengths are completely independent from each other and data streams with different line-rates and protocols can be transported on a single fiber or fiber pair. Traditional telecom signals (PDH, SDH/SONET), IP data (Ethernet, Gigabit Ethernet or 10G Ethernet) and storage data (8G/4G/2G/1G Fibre Channel) can therefore be transported over a single infrastructure without complex protocol conversion technologies.
WDM comes in two flavours: CWDM and DWDM. CWDM channel spacing is 20 nm and is typically used for un-amplified transmission up to 100 Km. DWDM uses cooled lasers and can also be amplified. The channel spacing of DWDM is typically 200GHz (ca. 0.8 nm). DWDM channels are usually used in the 1530-1560 nm band..
