A review of the technical options for evolving FITL to support small business and residential services

Fiber in the loop (FITL) is being implemented in many countries for telecoms services, with fiber directly entering larger business premises. Fiber already serves DLC´s, remote concentrators and street multiplexers at the 600-home level for customers and buildings requiring lower numbers of lines. Transport of video over fiber is becoming commonplace, now serving less than 2400 homes. This paper considers scenarios for fiber to penetrate further into the local loop by reviewing access service requirements and some FITL issues. It highlights enabling technologies for telecoms and video services and options for operators to roll out future services using FITL systems
