This PPT presentation is based on the topic WDM in Optical Network
WDM in Optical Network is very common topic for seminar presentation.
This ppt slide on WDM in Optical Network is a guidline for students or proffesional preparing for seminar presentation on WDM in Optical Network.
With wavelength division multiplexing (WDM) several optical signals can be transferred in a single optical fiber.
Both wavelength-division-multiplexing (WDM) networks with ring architecture and with a star architecture have been extensively studied as solutions to the ever increasing amount of traffic
Continued advancements in optical technology promise continued change the optical network evolves to ultimate goal of end-to-end wavelength services
Optical-layer technology will increase capacity, allowing the network providers to transport more then 40 times the traffic competition in the local exchange will ensure that bandwidth will become more affordable.
wavelength division multiplexing (WDM) provides a large number of high-speed channels on a single optical fiber by transmitting multiple data streams in the form of independently modulated wavelengths of light in the spectrum passed by a fiber. In this way this technology allows more efficient use of the huge capacity of an optical fiber but also poses new network design and many more.
Still now WDM technology is growing up, and some more new technology may come for our service.
so In essence, optical-layer technology will improve the way we live.
