Figure 2-29 shows a larger application with fiber in the riser, using the optical
extension capability of DDM-Plus or DDM-2000 FiberReach, to extend optical
bandwidth to individual floors. Satellite locations contain the DDM-Plus distant
terminal (DT) to convert the optical extension interface into four standard DS1
signals. Self-healing needs can be met with cabled ring or diverse routing. The
OC-3 bandwidth to customer locations also positions the network to deliver higher
bandwidth services, such as video.
