Westermo MCI-422-SM-SC30 is an industrial Ethernet media converter designed to bridge copper and fibre networks in demanding environments. It provides two independent conversion channels, enabling 10/100Base-TX Ethernet to be converted to 100Base-FX over single-mode fibre. The unit uses SC fibre connections (SC30 variant) and is well suited to extending network segments, improving noise immunity and supporting long-distance links where copper cabling is impractical. Housed in a robust industrial form factor for panel or DIN-rail installation, it is commonly used to interconnect switches, PLC networks and remote equipment across fibre backbones while maintaining reliable Fast Ethernet performance.

What does this unit do in an industrial network?
It converts Ethernet over copper (10/100Base-TX) into fibre Ethernet (100Base-FX) so you can run Ethernet over single-mode fibre where copper cabling is impractical or distance/EMC conditions favour fibre.
What Ethernet speeds does it work with?
On the copper side it is designed for 10/100Base-TX, and on the fibre side it uses 100Base-FX.
What fibre type is used?
This variant is for single-mode fibre. If you need multimode, you would typically look for the MM variant within the same converter family instead.
What fibre connector style does it use?
It uses SC fibre connectivity on the optical side (single-mode SC).
Is it a single-channel or multi-channel converter?
It is a two-channel electrical-to-optical Ethernet media converter, meaning it provides two conversion channels within one unit.
Do I need a matching device at the other end of the fibre link?
Yes. The far end must present a compatible 100Base-FX fibre Ethernet interface (for example, another media converter or a network switch with the appropriate fibre port).
Is it intended for long-distance fibre links?
Yes. The SC30 variant is typically selected for longer-reach single-mode fibre applications; achievable distance depends on the overall optical link budget, fibre condition and patching.
Does it require network configuration to operate?
It is used as a media converter rather than a managed network device, so it is typically installed inline to convert the physical medium (copper to fibre) without needing IP addressing or network setup.
What standards are relevant for industrial EMC environments?
It is associated with industrial EMC immunity/emission standards used in heavy industrial environments, including EN 61000-6-2 (immunity) and EN 61000-6-4 (emission), as referenced for conformity.
What is the difference between the short-reach and long-reach SC variants?
In this product naming, the SC designator refers to the SC fibre interface, and the number (such as 2 vs 30) is commonly used to indicate the intended optical reach class (shorter vs longer distance). The MCI-422-SM-SC30 is the long-reach single-mode option.
Can it be used to reduce interference issues compared with copper cabling?
Yes. Converting the link to fibre can help avoid issues that can affect copper cabling in industrial settings, such as susceptibility to electromagnetic noise and potential earthing differences between locations.
What should I check when selecting fibre patch leads for installation?
Use single-mode fibre patch leads with SC connectors to match the optical interface, and ensure your fibre type and patching are consistent end-to-end across the link.
- Extending 10/100 Ethernet connections over long distances using single-mode fibre (up to 30 km) where copper cabling is impractical
- Linking two separate Ethernet copper devices to fibre backbones in industrial networks via a compact two-channel media conversion solution
- Creating fibre uplinks between control panels, switch cabinets, and remote equipment rooms to reduce noise sensitivity compared with copper runs
- Connecting factory-floor Ethernet segments across large sites such as warehouses, production halls, and campus-style industrial facilities
- Building point-to-point fibre links between distributed process areas (e.g., pump stations, treatment stages, or remote monitoring points) and a central network location
- Supporting network expansion across outdoor routes or between buildings where electrical isolation and distance are key drivers
- Providing fibre connectivity for IP-based monitoring systems (such as cameras or instrumentation networks) located far from the main comms cabinet
- Integrating legacy copper-only Ethernet devices into existing single-mode fibre infrastructure without redesigning the wider network
- Establishing redundant or separated network paths by using dual conversion channels for parallel links in segmented network designs
- Bridging Ethernet across electrically noisy environments (motors, drives, and heavy machinery areas) by converting to fibre for the long run
