38、2343-1-2 IEC:2007 3 Terms and definitions For the purposes of this document, the following definitions apply. 3.1 dynamic chromatic dispersion compensator two-port in-line device that is capable of transforming, by internal or external automatic control, an input signal with time-varying dispersion
39、into an output signal in which an output channel dispersion value is set for a required level of value 3.2 operating wavelength range the specified range of wavelengths from iminto imaxabout a nominal operating wavelength I, within which a dynamic optical module is designed to operate with a specifi
40、ed performance 3.3 channel frequency range the frequency range within which a device is expected to operate with a specified performance. For a particular nominal channel central frequency, fnomi, this frequency range is from fimin= (fnomi- fmax) to fimax= (fnomi+ fmax), where fmax is the maximum ch
41、annel central frequency deviation. 3.4 insertion loss ripple the maximum peak-to-peak variation of the insertion loss within a channel frequency (or wavelength) range 3.5 channel spacing the centre to centre difference in frequency (or wavelength) between adjacent channels in a device 3.6 dispersion
42、 tuning time the longest elapsed time it takes a module to change a dispersion setting from an arbitrary initial dispersion value to a desired final dispersion value, when the resulting dispersion target tolerance is met 4 Test 4.1 General The characterization of a dynamic chromatic dispersion compe
43、nsator requires demonstration that those components or features within the module, together with that of the module itself, are capable of yielding the performance requirements as defined in the relevant specification. Where it can be adequately demonstrated that components or features have previous
44、ly met all of the requirements of a specific performance standard category, they may be declared as complying with that performance standard. This may obviate the need for repeat testing of components or features in such cases. Where this occurs, reference shall be made to the relevant test reports
45、or documentation. 4.2 Module Unless otherwise specified, all DCDC module test methods shall be in accordance with the IEC 61300 series.

46、working permitted without license from IHS-,-,-62343-1-2 IEC:2007 7 DCDC modules used for each test are intended to be previously unstressed new samples but may be selected from previously used samples if desired. Each test defines the number of samples to be evaluated. All measurements shall be car
47、ried out at standard test conditions, as defined in IEC 61300-1, unless otherwise stated. If the module is provided with an active temperature control, this shall be set at the setpoint specified by the manufacturer. The defined performance requirements apply to every combination of input and output
48、 port, over all polarization states and over all specified environmental conditions. 4.3 Spectral bands All tests are to be carried out to validate performance over the required operating wavelength range. As a result, single or multiple spectral bands may be chosen for the qualification and differing target specifications may be assigned to each spectral band. Table 1 is intended to provide guidance on the wavelength ranges of the various spectral bands. It is not intended for specification. Values of o
