Demands on access networks are increasing at an accelerating rate, requiring a clean-sheet approach to a truly scalable multi-service architecture. Zhone’s MXK intelligent terabit access concentrator reflects this new approach, featuring an initial 400 Gbps pure packet switching capacity and 2x10 Gbps redundant links to every slot. Beyond sheer bandwidth, MXK platforms leverage Zhone’s well-proven SLMS access operating system for sophisticated service intelligence, to guarantee high quality of experience for subscribers, along with ease of management to address rising costs of network operation.
In a PON (Passive Optical Network), each end user has an ONT (Optical Network Terminal) while the fiber terminates at a central office or remote cabinet in an OLT (Optical Line Terminal). Between the OLT and the ONT may be one or two stages of passive splitters, which split the connection to multiple end points (up to 64), and WDM combiners, when RF overlay services are also being offered.
