GLC-BX40-D-I Use Case
Metro Ethernet Aggregation over 40 km Single-Fiber with GLC-BX40-D-I-1000BASE-BX40-D
A service provider extends Metro Ethernet between central office and edge aggregation sites up to 40 km using a single-fiber bidirectional link. The GLC-BX40-D-I-1000BASE-BX40-D module slashes fiber counts by 50 %, supports DOM for real-time optical health monitoring, and ensures SLA-grade 1 Gbps throughput—delivering robust bandwidth growth while minimizing capex and operational overhead.
Enterprise Campus Backbone & DR Link via Single-Fiber Bidirectional Module
An enterprise IT team interconnects headquarters and a remote data center campus over a 40 km span on a single fiber to establish primary and disaster-recovery paths. By deploying GLC-BX40-D-I-1000BASE-BX40-D transceivers, they reduce fiber infrastructure costs, enable DOM-driven fault detection for proactive maintenance, and achieve seamless 1 Gbps connectivity that meets strict RPO/RTO requirements.
Industrial SCADA & Remote Site Control with 1000BASE-BX40-D Single-Fiber
An oil & gas operator links a remote pump station 35 km from the control center over a single-fiber bidirectional circuit. The GLC-BX40-D-I-1000BASE-BX40-D module delivers resilient 1 Gbps transmission in harsh environments, while DOM provides continuous optical diagnostics. This solution reduces field fiber deployment, accelerates troubleshooting, and guarantees high-availability SCADA control for critical infrastructure.
