Optical fiber cable for use in a dispersion managed cable system

An optical fiber cable for use in a dispersion managed cable system, comprising:

• optical fibers, at least some of the optical fibers exhibit a carefully controlled chromatic dispersion performance to support long distance, high data rate transmission;
• buffer tubes containing the optical fibers, at least some of the buffer tubes having at least one DMCS identification marking thereon and containing the optical fibers having a carefully controlled chromatic dispersion performance to support long distance, high data rate transmission, the buffer tubes being arranged such that DMCS identification marked buffer tubes with positive or negative dispersion optical fibers are grouped therein, and buffer tubes containing remaining fiber types are arranged in order of increasing Mode Field Diameter;
• and a cable jacket, the cable jacket comprising at least one DMCS identification marking thereon.
