Abstract
An apparatus comprises operationally coupled optical fiber segments that define an optical sublink. The optical sublink has link spans including a first link span and a second link span. The first link span has an average dispersion with a magnitude greater than zero. The second link span has an average dispersion with a magnitude greater than zero. The optical sublink has an end-to-end dispersion less than an end-to-end dispersion tolerance limit.

An apparatus, comprising:
- a plurality of operationally coupled optical fiber segments defining an optical sublink, the optical sublink having a plurality of link spans including at least a first subset of link spans and a correction link span, the optical sublink having an end-to-end dispersion and an end-to-end length,
- each link span from the first subset of link spans having an average dispersion and a link span length,
- the correction link span having an average dispersion and a correction link span length,
- the end-to-end dispersion of the optical sublink multiplied by the end-to-end length of the optical sublink being substantially equal to the product sum of the average dispersion and the link span length for each link span from the plurality of link spans minus the average dispersion of the correction link span multiplied by the length of the correction link span.
