Core Features & Market Positioning

The Moxa IMC-21GA-LX-SC distinguishes itself through its industrial-grade construction and advanced feature set, positioning it as a superior choice for mission-critical network infrastructure. Its ability to operate reliably in extreme temperatures from -40 to 75°C ensures uninterrupted performance in harsh conditions. The dual power inputs provide crucial network redundancy, minimizing downtime by automatically switching to a backup power source if the primary fails. This focus on reliability and environmental resilience is a key differentiator for Moxa in the industrial networking market.

Key Application Scenarios

This industrial media converter is ideally suited for extending network reach in challenging environments where standard Ethernet infrastructure cannot suffice. Common applications include connecting remote substations in power utilities, extending communication networks along railway lines, and enabling data acquisition in oil and gas facilities. Its long-distance single-mode fiber capability makes it perfect for linking geographically dispersed assets.

Practical System Integration Guidance

Integrating the Moxa IMC-21GA-LX-SC into an industrial network is straightforward due to its plug-and-play design. For copper connections, standard Cat5e/6/6a cables can be used for the RJ45 port, supporting auto-negotiation for speed and duplex settings. The SC fiber connector requires a single-mode patch cord with an appropriate length to reach the distant network segment or switch. Power can be supplied via terminal blocks, ensuring secure connections for DC power sources. DIP switches on the unit allow for quick configuration of basic operational parameters, such as link fault pass-through (LFP).

Operation and Risk Mitigation

Operating the IMC-21GA-LX-SC involves ensuring proper power supply and physical connections. The Link Fault Pass-Through (LFP) feature is critical for fault diagnosis; when enabled, if the fiber optic link fails, the copper Ethernet link is also deactivated, immediately alerting network administrators to a connectivity issue. This prevents devices from sending data across a broken link. Regular inspection of fiber optic connectors for cleanliness and integrity is recommended to maintain signal quality and prevent intermittent faults.

Scalability & Long-Term Value

The Moxa IMC-21GA-LX-SC offers significant long-term value by providing a reliable and high-performance solution for network expansion. Its Gigabit Ethernet capability ensures future-proofing as data bandwidth requirements increase. The ability to extend networks over 40 km using single-mode fiber offers substantial scalability for growing industrial operations. Furthermore, its compatibility with a wide range of industrial Ethernet switches and Moxa's broader product ecosystem facilitates seamless integration into evolving Industrial Internet of Things (IIoT) and smart factory initiatives.

Frequently Asked Questions

What is the maximum distance the Moxa IMC-21GA-LX-SC can transmit data?

The Moxa IMC-21GA-LX-SC is designed for long-range communication using single-mode fiber optics. It can reliably transmit data over distances of up to 40 kilometers. This extended range is crucial for connecting geographically dispersed industrial sites or remote equipment.

This capability makes it ideal for applications in utilities, transportation, and other sectors requiring extensive network coverage. The single-mode fiber and 1310 nm wavelength are optimized for these long-haul transmissions.

Ensuring the quality of the single-mode fiber optic cable and connectors is vital for achieving the full 40 km transmission distance without signal degradation.

Can the Moxa IMC-21GA-LX-SC be powered by both AC and DC sources?

This industrial media converter is designed to accept DC power inputs only, with a wide voltage range. It supports input voltages from 9.6 VDC up to 60 VDC, making it compatible with various DC power supplies commonly found in industrial settings.

The unit features dual power inputs, which is a critical feature for redundancy. If one power source fails, the converter automatically switches to the secondary input, ensuring continuous operation and minimizing network downtime.

This dual power input capability enhances the overall reliability and robustness of the network infrastructure where the IMC-21GA-LX-SC is deployed.

What type of fiber optic cable does the Moxa IMC-21GA-LX-SC use?

The Moxa IMC-21GA-LX-SC utilizes single-mode fiber optic cable. It is equipped with an SC connector for this purpose. Single-mode fiber is preferred for long-distance transmissions due to its lower signal attenuation and dispersion compared to multi-mode fiber.

The specific wavelength for operation with this single-mode fiber is 1310 nm. This combination is optimized for achieving extended reach up to 40 kilometers.

When connecting, ensure you use a single-mode SC-to-SC patch cord of appropriate length to link the converter to your fiber network.
