Background OverviewBackground Overview The increasing demand for bandwidth along with the fact that it is

relatively very expensive in many cases to lay new fiber implies that we must find ways to increase the capacity on existing fiber.

In metro environments, operators and city carriers have mostly built networks based on SONET/SDH technology, which are already operating at full capacities.

Moreover there are a variety of diverse formats that must be covered in metro environment including Storage Area Network (SAN), Gigabit Ethernet, 10- Gigabit Ethernet which require separate networks as SONET/SDH was not originally designed to handle them

Dense Wavelength Division Multiplexing (DWDM) is a scalable long term solution which addresses all these aspects along with non scraping of existing hardware
