Optical Transport Network (OTN) has evolved over the last few years to be the preferred technology for building DWDM (Dense Wavelength Division Multiplexing) back-bone and long distance optical networks for carriers.
This white paper explores ways of meeting the challenges and getting the most out of the fiber infrastructure without the need of adding additional fibers or getting into vast expenses.
PacketLight provides both active and passive solutions for single fiber transmission. The solutions range from 4 services up to 8 services using either CWDM or DWDM technology.
In this paper, we review the business case and implementation aspects for carriers and enterprises to use the SONET/SDH as the WAN between SAN islands.
