Course Outline
Introduction to PON and Fiber Access Networks
- Understanding GPON and its role within FTTH/FTTx access networks.
- Comparing GPON, EPON, and XGS-PON: standards, bandwidth capabilities, and use cases.
- Key advantages: high bandwidth, extended reach, passive infrastructure, and energy efficiency.
- Evolution roadmap: progressing 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 distinctions between residential and 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 calculating the power budget for a PON link.
- Selecting split ratios and analyzing their impact on reach and loss.
- Practical exercise: calculating a link budget for a real-world deployment scenario.
Network Design and Planning
- PON topology: centralized versus cascaded splitting strategies.
- Fiber capacity planning and route design for urban and rural deployments.
- Coexistence of GPON and XGS-PON via WDM1r for seamless upgrades.
- Practical exercise: designing a simple residential PON including a BOM and link budget.
Installation and Physical Deployment
- Fiber safety: laser handling, eye protection, and electrical safety near power lines.
- Fiber handling techniques: stripping, cleaving, cleaning, and inspection using a microscope.
- Best practices for fusion splicing and mechanical connectorization.
- Guidelines for OLT rack installation and ONT premises placement.
- Real-world scenario: deploying 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: progression from initial discovery (O1) to operation (O5).
- Practical exercise: configuring voice, video, and data services on a simulator.
Operation and Monitoring
- Applying the FCAPS model to GPON networks.
- Key performance indicators: Rx/Tx optical power levels, optical budget margin, and BER.
- Utilizing 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: employing a divide-and-conquer approach from subscriber side to OLT side.
- Addressing offline ONTs: authentication failures, OMCI timeouts, and rogue ONT detection.
- Diagnosing low optical power, macrobends, and dirty connectors using OTDR and VFL.
- Practical exercise: diagnosing a failing subscriber circuit using alarm data and OTDR traces.
Modern PON Standards and Future Evolution
- XGS-PON (G.9807.1 Amendment 1, May 2025): providing symmetric 10G for modern demands.
- 25G PON and 50G PON: next-generation frontiers for 5G transport and enterprise applications.
- Network slicing and intelligent ODN trends for 2026 and beyond.
- Strategies for migrating from GPON to XGS-PON while protecting existing investments.
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-specific 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
- Foundational knowledge of telecommunications and IP networking concepts.
- No prior experience with fiber optics or GPON is required.
Audience
- Telecommunications technicians and engineers.
- Field deployment and installation personnel.
- Network operations center staff beginning work with GPON infrastructure.
