This industrial network expansion card expands protective relay communication capacity, delivering deterministic peer-to-peer data transfers between separated electrical substations. The architecture integrates specialized high-bandwidth fiber optic transceivers functioning at a nominal \u003cstrong\u003e1300nm\u003c\/strong\u003e infrared wavelength optimized for transmission pathways over standard \u003cstrong\u003eSingle-Mode\u003c\/strong\u003e fiber optic infrastructure.\u003c\/p\u003e\n\u003cp\u003eOperating within critical utility grid automation grids, the \u003cstrong\u003eUR-7CM (UR7CM)\u003c\/strong\u003e enables teleprotection telemetry mapping, line differential processing data synchronization, and high-speed remote direct transfer trip (DTT) processing. This card connects directly into designated communication slot spaces behind the main chassis assembly faceplate, communicating directly over the host unit's native internal system backplane. Encased in a ruggedized, substation-hardened modular form factor, the module provides structural isolation against local electrical transients and high electromagnetic field interference (EMI) risks
