Fiber 101 and 202
Fiber 101 covers the fundamentals of fiber optics, while Fiber 202 focuses on practical installation, splicing, termination, and testing of fiber optic cables.
Fiber 101: Fundamentals
Fiber 101 introduces the basic concepts of fiber optics, including the types of fiber and their applications. Key points include:
- Multimode fiber: Has a larger core (typically 62.5 microns, sometimes 50 microns) and is used with LED light sources at wavelengths of 850 and 1300 nm. It is suitable for short-distance, lower-speed networks such as LANs .
- Singlemode fiber: Has a smaller core (~9 microns) and uses laser sources at 1310, 1490, 1550, and 1625 nm. It supports long-distance, high-speed applications like telephony and CATV .
- Fiber structure: Typical fibers consist of a core, cladding, and buffer coating .
- Standards: Telcordia GR-449 recommends that fiber cable build-up should not exceed two inches in depth at any point in the network . Fiber 101 tutorials often include videos and interactive content to help learners understand how optical fiber has improved communication systems .
Fiber 202: Practical Skills
Fiber 202 builds on the fundamentals and focuses on hands-on skills for working with fiber optic cabling:
- Installation: Running fiber cables in patch panels, equipment racks, and external enclosures.
- Splicing and termination: Techniques for joining fibers and preparing connectors for network use.
- Testing: Ensuring proper signal transmission and network performance using specialized equipment.
- Environments: Training covers both indoor and outdoor applications, including multimode and singlemode end-to-end cabling . This course is designed for learners who want to gain practical expertise in fiber optic network deployment and maintenance, complementing the theoretical knowledge from Fiber 101 .
Summary
- Fiber 101: Focuses on understanding fiber types, light propagation, and network applications.
- Fiber 202: Focuses on practical skills for installation, splicing, termination, and testing of fiber optic cables. Together, these courses provide a comprehensive foundation for anyone pursuing a career in fiber optic communications or network installation.
