  1. Operating System Conceptsin Optical Fusion Splicers. Darrin P. Newman CSc 4320

  2. What is Optical Fiber? • Optical fiber is basically a wire that is made of glass instead of copper.

  3. Why use Optical Fiber? • Higher speed- 2.5Gb/s vs 1.5 Mb/s • Signal strength -200Km vs 2.5 Km • Security • EMI- (electromagnetic interference) • Capacity- 32,000 channels vs 24 channels

  4. Why Optical Fiber?

  5. Fiber Splicing • Mechanical Splicing • Butt fibers together with matching gel in between fibers. • Requires high skill level • High splice loss (0.5 dB) • Degradation over time (2-5years)

  6. Fiber Splicing • Fusion Splicing • Low splice loss • Long lasting • Durable

  7. Optical Fiber Splicing

  8. Operating System Concepts • Process Management • Memory Management • Storage Management • Protection • Security

  9. Process Management • In early versions process management was not very critical because of basic structure of system. • Recently as new OS was launched noticeable problem has been response time.

  10. Process Management

  11. Memory management • Due to small size of OS this was not an issue • When PM splicer was introduced, previous machine version was upgraded causing memory to be full. • To remedy problem, several options had to be removed.

  12. Storage management • Storing of data is different than computer • Each compartment for storing data is fixed • Program storage, splice history, arc check history and images can only be stored in fixed location with a fixed size.

  13. Protection • Protection is needed so that user cannot modify certain aspects of the splicer • User menu and Supervisor menu

  14. Security • To protect from unauthorized users. • To protect if machine is stolen.
