Course Outline
Introduction to PON and Fiber Access Networks
- What is GPON and how it fits in FTTH/FTTx access networks
- GPON vs EPON vs XGS-PON: standards, bandwidth, and use cases
- Key benefits: high bandwidth, long reach, passive infrastructure, and energy efficiency
- Evolution roadmap: from GPON (G.984) to XGS-PON (G.9807.1), 25G PON, and 50G PON
GPON Architecture and Components
- OLT (Optical Line Terminal): role, placement, shelf architecture, and uplink options
- ONT/ONU (Optical Network Terminal/Unit): types, interfaces, and residential vs business models
- ODN (Optical Distribution Network): fibers, splitters (PLC), FDH, closures, and connectors
- Passive components: SC/APC, LC connectors, splice trays, and cable management
Optical Principles and Link Budget
- Wavelength plans: downstream 1490 nm and upstream 1310 nm
- Optical loss, attenuation, and the power budget calculation for a PON link
- Split ratio selection and its impact on reach and loss
- Practical exercise: calculate a link budget for a real-world deployment scenario
Network Design and Planning
- PON topology: centralized vs cascaded splitting strategies
- Fiber capacity planning and route design for urban and rural deployments
- Coexistence of GPON and XGS-PON via WDM1r for smooth upgrades
- Practical exercise: design a simple residential PON with a BOM and link budget
Installation and Physical Deployment
- Fiber safety: laser handling, eye protection, and electrical safety near power lines
- Fiber handling: stripping, cleaving, cleaning, and inspection with a microscope
- Fusion splicing and mechanical connectorization best practices
- OLT rack installation and ONT premises placement guidelines
- Real-world scenario: deploy a distribution point to multiple subscriber homes
Basic Configuration (Vendor-Neutral Concepts)
- OLT provisioning: PON ports, GEM ports, T-CONTs, and service profiles
- VLAN tagging, bandwidth profiles, and QoS for triple-play services
- ONT authentication methods: serial number, LOID, and password registration
- ONT state machine: from initial discovery (O1) to operation (O5)
- Practical exercise: configure voice, video, and data services on a simulator
Operation and Monitoring
- FCAPS model applied to GPON networks
- Key performance indicators: Rx/Tx optical power levels, optical budget margin, and BER
- Using generic EMS/NMS and OMCI for status, alarms, and remote management
- Common alarms: LOS, LOFi, DGi, TF, and their physical and logical causes
Troubleshooting Common Issues
- Systematic fault isolation: subscriber side to OLT side divide-and-conquer approach
- ONT offline: authentication failures, OMCI timeouts, and rogue ONT detection
- Low optical power, macrobends, and dirty connector diagnosis using OTDR and VFL
- Practical exercise: diagnose a failing subscriber circuit from alarm data and OTDR traces
Modern PON Standards and Future Evolution
- XGS-PON (G.9807.1 Amendment 1, May 2025): symmetric 10G for modern demands
- 25G PON and 50G PON: next-generation frontiers for 5G transport and enterprise
- Network slicing and intelligent ODN trends for 2026 and beyond
- When and how to migrate from GPON to XGS-PON while protecting existing investment
Best Practices, Safety, and Documentation
- Fiber safety and Class 3B laser handling procedures
- Documentation standards: labeling, cable records, as-built drawings, and asset databases
- Preventive maintenance: cleaning, inspection schedules, and closure management
Certification Preparation and Review
- Overview of certifications: FOA CFOT/CFOS, BICSI INSTF/TECH, and vendor tracks
- Relevant ITU-T standards: G.984 series, G.9807.1, and G.988 (OMCI)
- Exam topic mapping, key takeaways, and next steps for specialization
- Final practical assessment and Q&A
Requirements
- Basic understanding of telecommunications and IP networking concepts
- No prior fiber optic or GPON experience required
Audience
- Telecommunications technicians and engineers
- Field deployment and installation staff
- Network operations center personnel beginning work with GPON infrastructure
