Deliver more with less
The success of broadband services has been overwhelming, creating huge pressure on carriers to upgrade their access and backhaul networks. But budgets are tight and the underlying question remains: How can we change the current operational model and improve end-user experience while reducing operational expense? Can we deliver more bandwidth to more endpoints using fewer active sites in the network? Yes, we can.
A new operational model
WDM-PON (Wavelength Division Multiplexing-Passive Optical Network) is an innovative concept for access and backhaul networks. It uses multiple different wavelengths (WDM) over a physical point-to-multipoint fiber infrastructure that contains no active components (PON). The use of different wavelengths allows for traffic separation within the same physical fiber. The result is a network that provides logical point-to-point connections over a physical point-to-multipoint network topology. WDM-PON allows operators to deliver high bandwidth to multiple endpoints over long distances.
WDM-PON allows operators to deliver high bandwidth to multiple endpoints over long distances.
WDM delivers capacity and reach that enables operators to concentrate service creation engines and data processing in fewer sites that sit farther back in the network. The ultimate goal is to serve up to 1,000 endpoints with at least 1,000Mbit/s over a distance of up to 100km. This is only feasible when WDM is included in the access and backhaul networks. This WDM-PON-based model leads to a radical overhaul of existing operational models and, ultimately, to sustainable broadband delivery.
