1. UPM, DIAC. Open Course. March 2010 6. SPLICES AND CONNECTORS 6.1 Basics 6.2 Splices 6.3 Connectors

2. 6-2 6.1 BASICS Concept – Splices and connectors: ways of joining fibers – Differences Splice: permanent joint Connector: temporary joint – Duality with electric wires Optical splice is much more complex Optical connector is more precise and expensive

3. 6-3 6.2 SPLICES (I) Characterization – Attenuation  s (dB) Methods – Fusion Splicing (electric arc) – Mechanical/Adhesive Joining VIDEOS – On internet
