This technical report provides guidelines for accommodation and compensation of dispersion. These techniques are generally used in the 1550 nm region with cables incorporating conventional dispersion-unshifted single-mode category B1 fibre (see IEC 60793-1 and IEC 60793-2). Compensation refers to techniques that reduce the dispersion or dispersion-slope of a fibre-optic link to enable transmission at higher digital bit-rates. Accommodation refers to techniques that utilize dispersion to enable transmission at higher digital bit rates (e.g. by optical or electrical prechirping, dispersion-assisted transmission, receiver signal processing).
