Not compatible with HIRSCHMANN EAGLE, DRAGON, or GECKO series. Not compatible with GigaBit (1000BASE) uplink slots.
Selection Guide
Use the following criteria to determine whether the MM2-2FLM4 is the right module for your application:
- Fiber type needed: Multimode (MM) → MM2-2FLM4 ✓ | Single-mode (SM) → consider MM2-2FLS4 or MM2-2FLS15
- Distance requirement: ≤ 4 km → MM2-2FLM4 ✓ | > 4 km → single-mode variant required
- Port count: 2 ports → MM2-2FLM4 ✓ | 4 ports → MM4-2FLM4
- Speed requirement: 100 Mbps → MM2-2FLM4 ✓ | 1 Gbps → Gigabit media module required
- Temperature range: Standard industrial → MM2-2FLM4 ✓ | Extended/rail → MM2-2FLM4-EEC
- Protocol: Standard Ethernet → MM2-2FLM4 ✓ | PROFINET → MM2-2FLM4-PN

Replacement & Compatibility FAQ
Q: Can I use a third-party 100BASE-FX SC module instead of the MM2-2FLM4?
A: In some cases yes, but HIRSCHMANN switches may enforce OEM module coding via firmware. We recommend testing in a non-production environment first or contacting us for a pre-validated compatible alternative.
Q: Is the MM2-2FLM4 compatible with HIRSCHMANN EAGLE One routers?
A: No. The MM2-2FLM4 is a plug-in media module for MICE/RS series switches only and is not compatible with EAGLE series routers.
Q: What fiber cable type does the MM2-2FLM4 require?
A: 62.5/125 µm or 50/125 µm multimode fiber with SC connectors. Maximum distance is 4 km on 62.5/125 µm fiber.
Q: Can I mix MM2-2FLM4 and MM2-2FLS4 (single-mode) modules in the same switch?
A: Yes, MICE and RS series switches support mixed media module configurations across different slots.
Q: Do you offer a warranty on MM2-2FLM4 modules?
A: Yes. Konmask.com provides a 12-month warranty on all genuine modules and a 90-day warranty on tested surplus units. Terms available on request.
