Abstract

Loop economics (capital, operating cost, revenues, and present worth) is not well known for any loop technology, hampering deployment of new loop technologies. Local Exchange Carriers (LECs) must establish a base economic case for copper since the LECs have generally required fiber to be deployed when 'cost competitive with copper for POTS.' However, LEC management information systems do not capture copper costs in a format useful to loop planners. Results of one detailed analysis of loop economics are presented, showing loop density as key cost driver. Work in progress suggests how fiber in the loop (FITL) can be compared to copper's POTS cost, revenue and value structures. Using different revenue streams due to fiber's service enhancements, present worth analysis will demonstrate the range of loop densities that fiber may have an advantage in today.
