Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-38:Examinations and measurements - Group delay, chromatic dispersion and phase ripple

IEC 61300-3-38:2012 describes the measurement methods necessary to characterise the group delay properties of passive devices and dynamic modules. From these measurements further parameters like group delay ripple, linear phase deviation, chromatic dispersion, dispersion slope, and phase ripple can be derived. In addition, when these measurements are made with resolved polarization, the differential group delay can also be determined as an alternative to separate measurement with the dedicated methods of IEC 61300-3-32.

Dispositifs d’interconnexion et composants passifs à fibres optiques - Procédures fondamentales d'essais et de mesures - Partie 3-38: Examens et mesures - Retard de groupe, dispersion chromatique et fluctuation de phase

La CEI 61300-3-38:2012 décrit les méthodes de mesure nécessaires pour caractériser les propriétés du retard de groupe de dispositifs passifs et de modules dynamiques. A partir de ces mesures, on peut déduire d'autres paramètres tels que la fluctuation du retard de groupe, l'écart de phase linéaire, la dispersion chromatique, la pente de dispersion et la fluctuation de phase. En outre, quand ces mesures sont faites avec une polarisation résolue, le retard de groupe différentiel peut également être déterminé comme une alternative à une mesure distincte avec la méthode dédiée de la CEI 61300-3-32.

Optični spojni elementi in pasivne komponente - Osnovni preskusni in merilni postopki - 3-38. del: Preiskave in meritve - Skupinska zakasnitev, barvna razpršenost in fazna valovitost (IEC 61300-3-38:2012)

Ta del standarda IEC 61300 opisuje merilne metode, ki so potrebne za opis lastnosti skupinske zakasnitve pasivnih naprav in dinamičnih modulov. Iz teh meritev se lahko izpeljejo drugi parametri, kot so valovitost skupinske zakasnitve, linearna fazna deviacija, barvna razpršenost, strmina razpršenosti in fazna valovitost. Če se meritve izvedejo z razklonjeno polarizacijo, je mogoče določiti tudi diferenčno skupinsko zakasnitev kot alternativo ločeni meritvi z ustreznimi metodami iz standarda IEC 61300-3-32.
