MSM20-4FX-SM – 4-Port Single Mode Fiber Fast Ethernet Media Module by Hirschmann

The Hirschmann MSM20-4FX-SM is a single mode fiber Fast Ethernet media module for the Hirschmann PowerMICE MSP modular switch platform, providing four 100BASE-FX ports over SC connectors for long-distance industrial fiber links. Each port supports single mode 9/125 µm fiber with a link reach of up to 32.5 km and a 16 dB link budget at 1300 nm, making the MSM20-4FX-SM the right choice for wide-area plant networks, substation interconnects, and campus backbone links where multimode fiber fall short in distance. As a hot-swappable PowerMICE media module, it can be installed or removed from the MSP switch without interrupting system operation, and any combination of media modules can be populated across the switch’s available slots to achieve the desired port mix and media type. The module is powered entirely via the PowerMICE switch backplane at just 5W, with no need for dedicated power connections. Status LEDs covering power, mode, and link/data provide instant visual diagnostics. Operating temperature spans 0 to 60°C with storage down to -40°C, and the module meets IEC 60068-2-6 vibration and IEC 60068-2-27 shock standards alongside a full EN 61000-4 series EMC immunity compliance profile and EN 55032 Class A emissions rating. Approvals include EN61131, UL60950, cUL508, NEMA TS2, and C-Tick. A 60-month guarantee supports long-term industrial network reliability. The MSM20-4FX-SM suits energy utilities, water treatment, rail, and industrial campus environments demanding long-reach Fast Ethernet fiber switching on the Hirschmann PowerMICE platform.
