Broadband Optical Access using Centralized Carrier Distribution

It is now well known that there are various technologies for broadband access providing high-speed Internet access and triple-play services including data, voice, and video. Most well-established broadband access platforms now are digital subscriber line (DSL)-based and the Cable Modem-based. It is generally agreed that fiber-to-the-home (FTTH) provides the bandwidth and flexibility in upgrades when considering high-speed broadband access, especially with data rate of 1 Gbit/s or above. Passive optical network (PON) is considered as an attractive FTTH technology since it is highly cost-effective. A PON is a point-to-multipoint network architecture in which passive optical power splitters are used to enable a single optical fiber to serve multiple users. A PON consists of a service provider’s central office or head-end office and a number of optical networking units (ONUs) near AbstrAct
