optical faserverbindung with low polarisationsmodendispersion (pmd) and manufacturing process for it

摘要

An optical fiber link (300) comprises a plurality of optical fiber spans (305(k-1),...,305(k+6)) joined one to the other, the plurality of optical fiber spans including at least one first unidirectionally-spun optical fiber span (305(k-1),305(k+1),305(k+3),305(k+5)) and at least one second unidirectionally-spun optical fiber span (305k,305(k+2),305(k+4),305(k+6)) having mutually opposite spinning directions.
