Recent developments in digital baseband fiber in the loop systems

3aseband fiber in the loop (FITL) systems have been enjoying a resurgence in interest since the beginning of 1995. Originally, such systems were thought to be the best for deployment in local access applications by telephone companies. In particular, narrowband FITL systems were under intense development in the early 1990s. Bellcore's TR 909 standard, adopted in that time frame, reflects the interest and activity level of that time. With the announcement of the FCC's Video Dialtone ruling in 1992, attention focused on broadband access systems.
