IEC 61753-081-03:2023

Overview

IEC 61753-081-03:2023 is an international standard published by the International Electrotechnical Commission (IEC) that defines the minimum initial test and measurement requirements for non-connectorized single-mode fibre optic middle-scale 1 × N Dense Wavelength Division Multiplexing (DWDM) devices. Specifically targeting devices with arrayed waveguide gratings (AWG) used in outdoor protected environments (category OP), this latest edition covers DWDM devices with channel spacings of 50 GHz, 100 GHz, or 200 GHz and supports channel counts ranging from 16 to 64. The standard applies to devices with Gaussian and flat-top passband profiles and excludes those with dynamic electrical temperature control.

This performance standard ensures reliable operation of fibre optic components designed for harsh yet protected outdoor settings. It covers testing parameters related to optical performance, environmental durability, and mechanical reliability to support telecommunications infrastructure and data networks.

Key Topics

• Device Scope: Focuses on middle-scale 1 × N DWDM devices with 16 to 64 channels, ensuring applicability to scalable optical networking modules.
• Channel Spacing: Covers common DWDM channel spacings of 50 GHz, 100 GHz, and 200 GHz used in high-density wavelength multiplexing.
• Passband Profiles: Specifies performance requirements for devices with Gaussian and flat-top spectral passband shapes, relevant to different system designs.
• Environmental Category: Defines criteria for category OP - outdoor protected environments - where devices are exposed to environmental stressors but retain some protective housing.
• Testing Procedures: Includes initial optical and environmental testing such as vibration, shock, temperature cycling, dust and salt mist exposure, and optical parameters like polarization dependent loss and return loss.
• Exclusion Note: Devices utilizing dynamic electrical temperature control for stabilization are not covered under this standard.
• Normative References: Adopts multiple related IEC documents focusing on fibre optics testing methods and cable specifications to ensure consistent evaluation standards.
