DGE-894/A Use Case
Campus LAN Extension for University Facilities
In a multi-building university environment, pairing two DGE-894/A units over single-mode fiber (TX:1310 nm/RX:1550 nm) extends Gigabit Ethernet up to 20 km between academic blocks. IT teams can also mix one DGE-894/A with a DGE-891/B for seamless integration with existing fiber runs. The result: high-speed, low-latency connectivity across campus, centralized network management and reduced cabling costs.
Industrial Automation Network in Manufacturing Plant
A large automobile assembly plant deploys paired DGE-894/A converters (SC interface) to link PLCs, CNC machines and monitoring stations across a 15 km shop-floor fiber backbone. For legacy fiber segments, one endpoint uses DGE-891/B with a DGE-894/A at the opposite end. This setup ensures deterministic Gigabit performance, galvanic isolation and electromagnetic immunity, boosting production uptime and real-time control.
Long-Distance Surveillance and Security in Utility Infrastructure
A regional water treatment authority uses two DGE-894/A units to connect high-definition CCTV cameras and access control at remote pumping stations up to 20 km apart. Where older fiber exists, they pair DGE-894/A with DGE-891/B to optimize bandwidth. This solution delivers reliable, secure Gigabit links with optical isolation, enabling 24/7 monitoring, rapid fault detection and regulatory compliance.
