IEC 62343-5-2:2018 describes the measurement methods of dynamic crosstalk during port switching for 1 x N fixed-grid wavelength selective switches (WSSs). The objective of this document 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.

Overview

IEC 62343-5-2:2018 is an international standard published by the International Electrotechnical Commission (IEC) that defines test methods for dynamic crosstalk measurement in 1 x N fixed-grid wavelength selective switches (WSSs). This document specifically addresses WSSs aligned to ITU-T 50 GHz and 100 GHz fixed grid channel spacings with at least three output ports (N ≥ 3). The standard establishes consistent procedures for measuring both different-channel dynamic crosstalk and same-channel dynamic crosstalk during port switching operations. By standardizing these measurement techniques, IEC 62343-5-2 ensures reliable performance evaluation of WSS devices critical in modern optical fiber communication systems.

Key Topics

Dynamic Crosstalk in WSSs: Dynamic crosstalk is a noise phenomenon that arises during the switching of an optical signal to different output ports in a WSS. It varies transiently and affects signal integrity, making its accurate measurement essential.

Fixed-Grid Wavelength Selective Switches: Focused on WSS devices operating on a predetermined channel frequency grid (50 GHz or 100 GHz spacing), which are widely used in dense wavelength-division multiplexing (DWDM) systems.

Measurement Methodology: The standard describes apparatus setup, light source requirements (tuneable laser sources or broadband sources coupled with tunable filters), and detection equipment needed for dynamic crosstalk measurement.

Test Procedures: Includes step-by-step instructions on preparation, measurement of input power, insertion loss, noise power for both different and same channel crosstalk, and capturing transient noise power characteristics during port transitions.

Performance Parameters: Definitions and calculations involved in quantifying dynamic crosstalk are standardized to enable consistent reporting and comparison across devices and laboratories.

Applications

Optical Network Equipment Testing: IEC 62343-5-2 provides a vital framework for manufacturers and testing labs to verify the dynamic crosstalk performance of WSS modules used in optical switches and reconfigurable optical add-drop multiplexers (ROADMs).

Quality Assurance in DWDM Systems: The standard supports the development and deployment of high-performance WSS devices, ensuring minimal signal degradation due to crosstalk during dynamic switching operations.

Research and Development: Enables engineers designing next-generation optical modules to benchmark and improve port switching behaviors under standardized test conditions.

Telecommunication Infrastructure: Facilitates reliable assessment of optical components integral to backbone networks that demand high channel density, low noise, and stability under dynamic configurations.
