1. Operating System Concepts in 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

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.
