GLC-2BX-D-I Use Case
Smart-Grid Substation-to-Control-Center Fiber Link for SCADA Reliability
In a regional utility network, engineers deploy the GLC-2BX-D-I-1000BASE-BX10 SFP (1490 nm, 2-channels, industrial temp) as a single-fiber bidirectional link between remote substations and the central SCADA host. Operating across –40 °C to +85 °C and up to 10 km, this module ensures uninterrupted telemetry, reduces rack space by 50%, and lowers mean time to repair (MTTR) for mission-critical power distribution.
Offshore Platform to Shore Data Transmission for Oil & Gas Monitoring
An offshore oil platform integrates the GLC-2BX-D-I-1000BASE-BX10 SFP 1490 nm transceiver over existing fiber to stream real-time sensor, CCTV, and VoIP traffic to an onshore control center. Supporting industrial-grade temperatures and dual-wavelength channels, it delivers 1 Gbps throughput across 10 km, cutting project CAPEX by 30% and enhancing operational safety with deterministic, low-latency communications.
Industrial Campus Metro Ethernet Ring Extension in Harsh Environments
A large automotive plant extends its redundant Metro Ethernet ring into remote processing units using the GLC-2BX-D-I-1000BASE-BX10 SFP (1490 nm, 2-channels). Rated for extreme temperatures and plug-and-play with standard switches, it provides 1 Gbps fiber connectivity up to 10 km, simplifies network topology by eliminating dual-fiber runs, and boosts production uptime with carrier-grade reliability.
