The CMC-1550 Modal Content Analyser from Arden Photonics is an advanced measurement system designed specifically for the characterization of few-mode fibers and hollow-core fibers with complex internal structures. As specialty fiber technologies continue to evolve and support increasingly demanding applications, understanding how individual propagation modes behave within a fiber has become critical for both fiber development and manufacturing quality control. The CMC-1550 provides the detailed modal analysis required to gain this understanding and optimize fiber performance.The system consists of two separate units: a launch unit and a receiver unit. Together, these units employ the Spatially and Spectrally Resolved Imaging (S²) technique to identify, characterize, and analyze the individual modes propagating within the fiber under test. This sophisticated approach enables users to investigate the behavior of each guided mode in detail, providing valuable information that is difficult or impossible to obtain using conventional test methods.The CMC-1550 measures key modal characteristics such as modal intensity, modal phase, differential group delay (DGD), mode-dependent propagation loss, and mode-coupling effects. By examining these parameters, engineers and researchers can gain a comprehensive understanding of how energy propagates through the fiber and how different modes interact with one another.A particular strength of the CMC-1550 is its ability to reconstruct the propagation mode profiles and phases of the guided modes within the fiber. This capability provides a visual and quantitative representation of modal behavior, helping users validate fiber designs, improve coupling efficiency, enhance manufacturing processes, and identify potential performance limitations before fibers are deployed in real-world applications.The instrument also calculates the relative intensity of each higher-order mode compared to the most strongly excited mode, often expressed as Multipath Interference (MPI). In addition, it determines the Differential Group Delay associated with each propagation mode, providing critical information for applications where signal quality, bandwidth, and mode management play an important role.Designed for specialty fibers with diameters up to 400 μm, the CMC-1550 enables researchers, engineers, and manufacturers to fully characterize the modal performance of advanced optical fibers.
