Couplers for fiber-in-the-loop systems

Couplers will play an important role in the deployment of fiber-in-the-loop (FITL) systems. Corning is currently using a planar integrated optics technology to manufacture couplers that are well-suited for FITL applications.

Single-mode integrated-optics branching devices for fiber-in-the-loop networks

Passive optical networks (PON) potentially may require optical splitting ratios ranging from 1x2 to 1x32, the maximum spilt recommended by Beilcore SR 1681. In anticipation of this, Corning has developed a monoilthic 1x16 single-mode splitter that offers significant performance advantages for PON using the same integrated-optics in glass technology that currently produces 1x2, 1x4 and 1x8 devices. This paper will review the performance characteristics of lxN planar spiltters, including the new Ix 16. Additionally, preliminary results will be shown for developmental 2xN devices.
