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

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

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

SPLICES (II) Splicing Machine

CONNECTORS (I) Characterization – Attenuation  c (dB) – Return Losses Interface reflections R > dB Types TYPEATN(dB), singlemodeATN(dB), multimodeRETURN LOSSES (dB) ST≤ 0.5 ≥ 40 FC≤ 0.35≤ 0.5≥ 50 SC≤ 0.35≤ 0.5≥ 50 LC≤ 0.35≥ 40 FC / APC≤ 0.35≥ 60 SC / APC≤ 0.35≥ 60
