NEU3044G Industrial Gigabit 4-Port RJ45 + 4x SFP Managed Ethernet Switch

NEU3044G is an industrial managed Ethernet switch built to connect field devices with Gigabit performance while extending networks over fiber. With 4x Gigabit RJ45 ports and 4x 1G SFP uplinks, it enables flexible designs that reduce electromagnetic interference risk and support longer distances than copper cabling.

In industrial networks, stability depends on traffic control as much as on hardware. NEU3044G provides Layer-2 management features to help isolate production cells and prioritize critical data. VLAN segmentation separates automation, security, and office traffic on shared infrastructure. QoS and rate limiting protect time-sensitive communications from congestion. Port mirroring supports troubleshooting and commissioning, and storm suppression helps prevent broadcast incidents from spreading across the plant.

For applications that cannot tolerate downtime, NEU3044G supports ring redundancy with fast self-healing. A typical deployment is a fiber ring linking multiple cabinets across a factory floor or along a transportation corridor. Each cabinet uses the SFP ports for ring links, while RJ45 ports connect local endpoints such as PLC/RTU, industrial PCs, gateways, and cameras. This topology reduces single points of failure and simplifies maintenance because a single fiber break does not stop the entire system.

Typical applications include factory automation lines, smart transportation infrastructure, highway tunnels, and distributed video surveillance systems. The 1G SFP uplinks are especially useful for backhauling aggregated camera streams or connecting remote control stations over long distance links. IGMP snooping improves multicast efficiency for surveillance and monitoring environments.

The rugged, fanless design supports DIN-rail mounting in compact spaces and helps lower maintenance requirements. Dual redundant DC power input improves availability during power transitions. NEU3044G is CE, FCC, RoHS certified and backed by a 5-year warranty.

A datasheet is available for network engineers who need full details on interfaces, environmental limits, and management functions. For accurate selection, confirm the required fiber connector type, wavelength, and distance for the SFP modules.
