IEC 61753-081-06:2023

Overview

IEC 61753-081-06:2023 specifies the performance standard for non-connectorized single-mode fibre optic middle-scale 1 × N DWDM (Dense Wavelength Division Multiplexing) devices, where 16 ≤ N ≤ 64, intended for extended outdoor protected environments (category OP+). This IEC International Standard outlines the minimum initial test and measurement requirements, as well as the severities each device must fulfill for qualification. The standard covers both Gaussian and flat-top passband profile DWDM devices, with channel spacing options of 50 GHz, 100 GHz, or 200 GHz. Devices with dynamic electrical temperature control are specifically excluded from the scope.

Key Topics

• Device Scope: Applies to non-connectorized, single-mode, 1 x N arrayed waveguide grating DWDM devices with middle-scale channel counts (16 to 64).
• Operating Environments: Targets devices designed for extended outdoor protected environments, ensuring reliable operation under challenging outdoor conditions.
• Channel Spacing: Addresses devices with channel spacing of 50 GHz, 100 GHz, or 200 GHz, compliant with ITU-T G.694.1 or custom grids.
• Performance Profiles: Includes requirements for both Gaussian passband profile and flat-top passband profile DWDM devices.
• Exclusions: Does not apply to devices with dynamic electrical temperature control.
• Testing: Specifies rigorous initial test and measurement procedures in accordance with IEC 61300 series, covering optical, mechanical, and environmental performance. Tests include:
  • Attenuation (insertion loss)
  • Channel non-uniformity
  • Passband width (1 dB and 3 dB)
  • Passband ripple
  • Channel crosstalk (adjacent, non-adjacent, total)
  • Polarization Dependent Loss (PDL)
  • Polarization Mode Dispersion (PMD)
  • Chromatic dispersion
  • Return loss and directivity
  • High optical power performance
  • Environmental robustness (temperature, humidity, vibration, shock, dust, retention)
• Documentation: Requires comprehensive test reports for evidence of compliance.

Applications

DWDM technology and devices conforming to IEC 61753-081-06:2023 play a critical role in high-capacity fiber optic network deployments. Key practical applications include:

• Metro and Long-Haul Networks: Supporting high-density wavelength multiplexing for broadcasting multiple channels over a single fibre, maximizing bandwidth efficiency.
• Outdoor Network Nodes: Ensuring durability and performance when deployed in extended outdoor protected environments such as telecommunications cabinets, street-side terminals, or field nodes.
• Telecom Infrastructure: Use in passive optical networks (PONs), carrier-grade transport networks, and enterprise backbones that require robust, passive, multi-channel wavelength management.
• Network Upgrades and Expansions: Seamless integration into existing infrastructures when expanding channel count or enhancing network bandwidth, while maintaining strict optical performance.
• Utility and Smart Grid Networks: Providing reliable, multiplexed transport for critical infrastructure communication that demands resilient, maintenance-free passive optical devices.
