Paper Abstract

An overview of the passive components that have been developed by Technologies for subscriber loop applications will be presented. The paper will cover new products and technologies that have allowed to introduce passive components that will allow optical services to be cost-effectively delivered to the subscriber. The types of devices discussed will include the low cost Subscriber Loop Coupler and the new singlemode monolithic multiport coupler arrays. The paper will highlight the volume manufacturing process that is used by to fabricate the Subscriber Loop Coupler as well as the wavelength-flattened non-50/50 splitters that have been developed for passive optical networking. Characterization of the monolithic multiport coupler arrays will also be presented. Specifically the broadband (wavelength-flattened) operation of the monolithic 1 x6 and 1 x7 couplers across the 1 250 to 1 600nm window will be covered. Applications in which the new monolithic coupler arrays and the Subscriber Loop Couplers can be used in the local loop will also be discussed.
