Abstract :
Fiber-in-the-loop (FITL) systems enable the distribution transport of existing telecommunications services and future broadband services over fiber optic media. An FITL system comprises a host digital terminal (HDT) connected to some number of optical network units (ONUs) via a fiber optic passive distribution network (PDN). Each ONU provides metallic service interfaces via short drops consisting of metallic wire pairs or coaxial cable. FITL systems that carry plain old telephony services (POTS) are referred to as "POTS FITL" systems. FITL systems that deliver VDT services or combined VDT and telephony services are referred to as "VDT FITL" systems. There are a number of architectural alternatives for VDT FITL, including configurations involving the use of parallel technologies for transporting video signals in the distribution. The authors discuss network operations and powering in particular.<>
