I can comment on the CM series cables. They are specified in the National Electrical Code for "Communications" applications. CM is the general construction, but has limits as to where it can be used in the building. CMR is designed for use inside walls (R = Risers) and CMP is designed for use in air handling spaces (P = plenum). CMP can replace CMR which can replace CM. All of these cables can also replace their equivalent Class II or Class III cables - e.g., CMP can replace CL2P.
