Overview
IEC TR 62343-6-12:2023 is a Technical Report published by the International Electrotechnical Commission (IEC) addressing dynamic modules used in optical communication networks. This specific document, titled Dynamic modules - Part 6-12: Design guidelines - Survey results on performance specifications for 1 × N wavelength selective switches, presents the summarized results of a comprehensive industry survey focusing on performance specifications for 1 × N wavelength selective switches (WSS). The outcomes serve as a valuable reference for establishing standardized performance values and developing future standards for WSS devices within the context of IEC 62343-3-3.
Wavelength selective switches are critical components in reconfigurable optical add-drop multiplexers (ROADMs) within dense wavelength-division multiplexing (DWDM) networks. The report provides industry insights and guidance, consolidating real-world proposals and recommendations from WSS manufacturers and users.
