Fiber Optic Network Design Guide: Architecture and Planning
Designing a fiber optic network requires careful planning of topology, cable types, connector choices, and equipment placement. A well-designed network minimizes costs and maximizes performance.
Network Topologies
Star topology is most common for FTTH and enterprise LANs. Ring topology provides redundancy for metro networks. Point-to-point for long-haul links. Tree topology for PON networks using splitters.
Fiber Selection
Single-mode (OS2) for distances over 500m. Multimode (OM3/OM4/OM5) for data centers and short links. Loose tube cables for outdoor. Tight-buffered cables for indoor. Armored cables for direct burial.
Connector Planning
SC connectors for GPON/EPON networks. LC for high-density data centers. MPO/MTP for 40G/100G/400G parallel optics. FC for test equipment. Consider adapter density, accessibility, and future expansion.
Design Checklist
Calculate power budget, verify reach requirements, plan cable routes, document splice locations, label all fibers, plan for future growth, and include test access points.
