Abstract

Det er beskrevet en fiberoptisk pakke som omfatter i det minste to fiberoptiske anordninger eller komponenter (102, 104, 106, 118, 120, 122, 124) som er koblet sammen ved hjelp av smeltefiberkobling (fused fibre coupling). Pakken omfatter typisk to eller flere fiberoptiske akselerometere og kan ha redusert størrelse sammenlignet med fiberoptiske pakker i henhold til tidligere kjent teknikk på grunn av den reduserte lengde av optisk fiber som fordres for å forbinde anordningene eller komponentene.
