There was little demand for actual service delivery to multiple end users, although an occasional large business customer might require as much as an OC-3 or OC-48, Megabit Ethernet, Fibre Channel, or other connection for day-to-day business operations. Times have changed. Today, fiber is being deployed much deeper into the network, both for business and residential consumers. The demand for high-speed voice, data, and video services is escalating, and new distribution architectures must be added to OSP networks to reach these customers. However, serving the small business and residential customer requires architecture that can efficiently connect millions of users onto a local network. Fiber-to-the-premises (FTTP) systems, based on passive optical network (PON) architecture, provide the access piece to traditional OSP networks for bringing multiple services to multiple business and residential customers. PON – Catalyst for the FTTP Revolution PON architectures are optical transmission systems designed to carry transmission signals via fiber-optic cable from the central office (CO) directly to the end user – such as a business, multi-tenant unit, or individual home. The network is passive because once the signal leaves the central office, there are no powered electronics or optical components involved. The signal is guided through the fiber to the end user by connecting and splitting components, traveling up to, and in some cases, exceeding 20 km. At the end user, the optical signal is converted back to electrical by an optical network terminal (ONT) for use as .
