適用范圍：This part of IEC 61282 provides definitions of dispersion penalty and other related penalties.It describes the direct measurement of these penalties using a BER test set and thecalculation of the penalties from time-resolved chirp (TRC) data. Annex A provides the theoryfor power penalty calculations.The calculations are valid for all types of single longitudinal mode (SLM) laser transmittersintended for use in telecommunications applications at data rates of 2,5 Gbit/s and higher withNRZ modulation format. These include but are not limited to directly modulated DFB lasers,DFB lasers with integrated electro-absorption modulators, and DFB lasers with external Mach-Zehnder modulators. This technique is not suitable for multiple longitudinal mode (MLM)lasers or LEDs.Chromatic dispersion induced power penalty values in this technical report are characteristicsof the transmitter, which is considered to be the device-under-test (DUT). Other power penaltysources, such as nonlinear effects and amplifier noise are not covered by this document.Since dispersion penalty for a transmission link depends on the transmitter, receiver andfibre, the dispersion penalty parameter for a transmitter is based on a specified fibredispersion and receiver characteristic, which should be reported with the test results.
