Tiếng Việt Fibre-optic links
Fundamentals of fibre-optic communication lines — light in fibre, attenuation and dispersion, fibre and cable types, link budgets, passive and active infrastructure, splicing, OTDR, faults, standards.
Physics of the fibre link
- Fibre-optic links: how light carries data
- How light propagates: reflection, modes, numerical aperture
- Attenuation and transmission windows
- Dispersion and bandwidth
- Fibre types: G.65x single-mode, multi-mode grades, specialty fibres
- Non-linear effects: SPM, XPM, FWM, Brillouin and Raman
- Reflections, reflectance and optical return loss
- How optical fibre is made: preforms, drawing, coating, proof test
- Fibre reliability and ageing: strength, fatigue, hydrogen, radiation, lifetime
Link design and passive plant
Active optical infrastructure
- Active optical infrastructure: what lights, amplifies, switches and watches the fibre
- Transceivers as the active end of the link: matching the module to the fibre
- Amplifiers and regeneration: EDFA, Raman, SOA, OEO
- Transport and access equipment: media converters, transponders, ROADMs, OLT/ONU, protection
- Monitoring and management: DDM, OSC, OCM, RFTS, alarms
Operations: splicing, testing, maintenance
- Splicing and termination: fusion, mechanical, pigtails, field connectors
- Testing and measurement: LSPM, OTDR, return loss, inspection
- Reading an OTDR trace: events, dead zones, ghosts, gainers
- Endface inspection and cleaning: IEC 61300-3-35 grading and methods
- Fibre characterization: CD, PMD, spectral attenuation, ORL, latency
- Fibre plant faults and how they show up
- Maintenance and restoration: keeping a plant alive for 25 years
- Safety and handling: lasers, glass, chemicals, live fibre, equipment
