A system and corresponding method for housing circuit boards is provided. The circuit boards may differ in two physical dimensions. The circuit boards are placed in circuit board housings within an enclosure. Substantially planar positionable enclosure partitions of various lengths are strategically placed within the enclosure in order to form the circuit board housings. The positionable enclosure partitions provide a means to create circuit board housings that differ from one another in both a first dimension and a second dimension.

A chromatic dispersion compensation system for an optical transmission system incorporates circuitry which determines the length of an optical fiber extending between an output amplifier and an input amplifier. Based on fiber type, the total chromatic dispersion on the fiber is determined. Compensation can then be automatically implemented.
