Magnum RPMs and BPMs are used in Magnum products, including Magnum Concentrators and bonus port options on Magnum hubs. They provide full-featured support for all standard Ethernet media types. Magnum RPM models include multi-mode fiber and single-mode fiber, BNC (with termination switch), TP (with uplink switch), AUI, and DTE. Five Magnum BPMs contain a compact local bridge module which isolates local traffic from central network traffic, improving the efficiency of both.
