DWDM TECHNOLOGY
Dense Wavelength Division Multiplexing (DWDM) is a revolutionary technology, with point-to-point DWDM
systems representing the first phase in the evolution of Optical Transport Networking. DWDM is the most
cost-effective way to expand capacity than some other alternatives such as adding fibre or replacing current
capacity systems. Laying new fibre is expensive, particularly for long routes, and its installation can take too
long to satisfy customers. TDM technology is no longer able to keep pace with the emerging ultra-broadband
data backbone demands.
Point-to-point links upto 640 km with ADD-DROP capability in the
long-haul/very-long haul backbone networks for
Applications of Alleviating fibre exhaustion problems

ELEMENT MANAGEMENT SYSTEM
C DWDM 3200 has SNMP based Element Management System (EMS).
EMS installs, monitors, controls and configuraes the DWDM link
through an EMS Manager. EMS supports CORBA for the North Bound
Interface. The Manager is connected to the system through a 10 Base T
Ethernet Interface. It can be physically connected to any Network
Element in the DWDM link.
