The analog local loop: a growing revolution in optical transmission

To provide an economic justification for the widespread deployment of optical fiber in the local loop, it may be necessary in some situations to install networks which will carry only telephony but can be upgraded to provide broadband services.

Description
Summary:To provide an economic justification for the widespread deployment of optical fiber in the local loop, it may be necessary in some situations to install networks which will carry only telephony but can be upgraded to provide broadband services. Methods by which this may be achieved using analog carrier techniques are discussed. Passive optical networks (PONs) are considered, and the application of plain old telephone service (POTS) and broadband services over PONs is considered. Frequency planning and future trends are summarized.< >
