Method for manufacturing optical fiber cable with optical fibers whose chromatic dispersion value are uniformed

A method for manufacturing an optical fiber cable by connecting a plurality of spans having n optical fibers, n being an integer not less than 2, comprising:

• arranging a first span of n optical fibers having identifiers different from each other in order of the magnitude of chromatic dispersion values to assign numbers;
• arranging a second span of n optical fibers in the reverse order of the magnitude of chromatic dispersion values to assign numbers;
• and
• connecting the optical fibers having the same number in the first span and second span.

A method for manufacturing an optical fiber cable by connecting a plurality of spans having n optical fibers, n being an integer not less than 2, comprising:

• providing a first span of n optical fibers having identifiers different from each other;
• providing a second span of an optical fibers having identifiers different from each other;
• the identifiers of the n optical fibers of the second span in the reverse order of the magnitude of chromatic dispersion values being respectively identical to the identifiers of the n optical fibers of the first span in order of the magnitude of chromatic dispersion values;
• providing a kth span of n optical fibers wherein k is an integer not less than 3;
• calculating the sum of chromatic dispersion values of optical fibers from the first span to a (k−1)th span having the same identifier to arrange the respective optical fibers from the first span to the (k−1)th span in order of the magnitude of the sum of chromatic dispersion values, in relation with the kth span;
• assigning identifiers different from each other to the n optical fibers of the kth span, the identifiers of the n optical fibers of the kth span in the reverse order of the magnitude of chromatic dispersion values being respectively identical to the identifiers of the n optical fibers of the first to (k−1)th spans in order of the magnitude of chromatic dispersion values;
• and
• connecting the optical fibers from the first to the kth spans having the same identifier.
