What is BS EN IEC 62343-5-2 - Dynamic modules about?
BS EN IEC 62343 is a series on Dynamic modules. Dynamic module is nothing more than a module created at run-time, with the same exact properties as a static module, plus one additional property called module. BS EN IEC 62343-5-2 describes the measurement methods of dynamic crosstalk during port switching for 1 x N fixed-grid wavelength selective switches (WSSs).
The objective of BS EN IEC 62343-5-2 is to establish a standard test method for different-channel dynamic crosstalk and same-channel dynamic crosstalk that occur when a particular optical channel signal is switched to the specific branching port against a common port in ITU-T 50 GHz and 100 GHz fixed grid 1 x N (N ≥ 3) WSSs.

Why should you use BS EN IEC 62343-5-2 - Dynamic modules?
Dynamic crosstalk is attributed to both channel crosstalk (due to same wavelength and/or other wavelengths) and port isolation. It is predicted to change during port switching operations and is a significant performance issue studied and summarized in IEC TR 62343-6-9 for 1 x N (N ≥ 3) wavelength selective switches (WSSs). Dynamic crosstalk exists in actual 1 x N (N ≥ 3) WSSs in IEC TR 6234369 and predicted that it would influence transmission properties to some extent when a specific channel passes through the WSS.
BS EN IEC 62343-5-2 standardizes the measurement method of dynamic crosstalk of 1 x N (N ≥ 3) WSSs. BS EN IEC 62343-5-2 is based on OITDA DM 01 from the Optoelectronic Industry and Technology Development Association (OITDA). Measurement conditions of the optical power of noise terms in a dynamic state are specified in BS EN IEC 62343-5-2. Those are the measurement environmental condition, input power, applied electric voltage and current is within the specification defined by the DUT, measurement time resolution and measurement sampling points is determined by the specification and device principle of the DUT, including port switching time, static crosstalk and dynamic crosstalk, measurement conditions, including the spectral linewidth of the TLS and the wavelength accuracy to ITU-T grid centre wavelength is determined by the specification and the device principle of the DUT, including the spectral pass band and the optical power of the noise at a branching port is measured in a dynamic state. It is a combination from an initial state to a final state during port switching. Power is measured in the channel of conducting port pairs determined by the port number of the DUT, the ITU-T fixed grid channel spacing, channels and the channel frequency range. Using BS EN IEC 62343-5-2 you can describe the measurement methods of dynamic crosstalk during port switching for 1 x N fixed-grid wavelength selective switches (WSSs).
