Space Division Multiplexing (SDM) Products

Continuously increasing demand for bandwidth and the potential of a ‘capacity crunch’ has driven research to investigate alternative transmission solutions that can be readily introduced into current networks. Using the spatial dimensions to transmit through optical fiber has led to the development of Few Mode Fiber (FMF) and Multi-Core Fiber (MCF) and associated components. Phoenix offers a range of components for operation in such systems using its in-house fiber processing technologies.

New products are in continuous development in this expanding field.
