HIRSCHMANN MM3-4FLM4 Media Module – Mice3 Series
In a modern industrial facility, network downtime is never just an inconvenience — it can halt an entire production line, trigger safety shutdowns, and cost thousands of dollars per minute. When a managed switch loses its fiber uplink capability due to a failed or missing media module, the entire network segment it serves goes dark. Operators lose visibility into PLCs, drives, and sensors. The HIRSCHMANN MM3-4FLM4 exists precisely to prevent this scenario: a purpose-built fiber media module that slots directly into the Mice3 modular switch platform, restoring and extending fiber connectivity with the robustness that industrial environments demand.
Within the Mice3 modular switch family, the MM3-4FLM4 occupies a critical role as a 4-port Fast Ethernet fiber expansion module. HIRSCHMANN — a brand synonymous with industrial networking since the 1980s and now part of Belden — engineered this module to meet the stringent demands of process automation, power utilities, and transportation infrastructure worldwide. Its plug-and-play integration with the Mice3 chassis makes it a go-to spare and upgrade component for system integrators and plant engineers managing fiber-based ring or star topologies.

Key Features & Benefits
- 4-Port Fiber Expansion: Adds four 100BASE-FX multimode fiber ports to a Mice3 switch chassis, maximizing uplink density without replacing the base unit.
- Hot-Swap Capable: Designed for insertion and removal without powering down the switch, minimizing maintenance windows in 24/7 production environments.
- EMI Immunity: Fiber optic transmission eliminates susceptibility to electromagnetic interference common in motor-drive-heavy industrial floors.
- Long-Distance Segment Extension: Multimode fiber supports inter-building and cross-facility runs far beyond copper Ethernet limits.
- Genuine OEM Component: Ensures full compatibility, firmware recognition, and HIRSCHMANN diagnostic support within the Mice3 management interface.
- Compact Modular Design: Preserves rack space while delivering high port density — critical in compact control cabinet installations.
Industry & Equipment Applications
- Process Manufacturing: Chemical plants, refineries, and food & beverage facilities requiring noise-immune fiber backbones between control rooms and field devices.
- Power Utilities & Substations: IEC 61850-compliant substation automation networks where fiber isolation is mandatory for safety and reliability.
- Transportation & Rail: Trackside and station networking where vibration, temperature extremes, and EMI demand fiber-based infrastructure.
- Water & Wastewater Treatment: Remote pump station connectivity over fiber rings managed by Mice3 switches.
- Automotive Assembly: Robot cell and conveyor network segments requiring deterministic, interference-free communication.
- Building Automation & Airports: Large-campus fiber backbone extensions for BMS and security systems.

Frequently Asked Questions
Q: Is the MM3-4FLM4 compatible with all Mice3 chassis variants?
A: The MM3-4FLM4 is designed for the Mice3 modular platform. Compatibility depends on the specific chassis model and available expansion slots. Please share your chassis part number when inquiring so we can confirm fit.
Q: Is this a new or refurbished unit?
A: We stock both new-in-box and tested-surplus units depending on availability. The condition will be clearly stated in your quotation. All units pass our QA process regardless of condition.
Q: What fiber type does the FLM4 interface support?
A: FLM4 denotes 100BASE-FX over multimode fiber with SC duplex connectors. It is not compatible with single-mode fiber without an appropriate converter.
Q: Can I order a single unit, or is there a minimum order quantity?
A: We supply single units as well as bulk project quantities. There is no minimum order requirement for standard inquiries.
Q: How long does international shipping take?
A: Express courier (DHL/FedEx) typically delivers within 3–7 business days to most destinations. We provide tracking numbers upon dispatch.
