Overview
ISO/IEC/IEEE 8802-3:2021/Amd 13:2022 (IEEE 802.3ct amendment) defines physical layer and management specifications for 100 Gb/s Ethernet operation over dense wavelength division multiplexing (DWDM) systems. Published as Amendment 13 to the IEEE/ISO/IEC Ethernet standard, it adds new clauses and an annex that address 100 Gb/s single‑mode fiber operation using a combination of phase and amplitude modulation with coherent detection for reaches of at least 80 km.
Key topics and requirements
- 100 Gb/s physical layer (PMD) - Adds PMD specifications for operation over DWDM black links and single‑mode fiber (SMF).
- Modulation & detection - Specifies use of combined phase and amplitude modulation with coherent detection (e.g., dual‑polarization formats referenced in industry implementations).
- Management parameters - Defines management attributes needed to configure, monitor and manage 100 Gb/s links over DWDM, including performance and operational parameters.
- Reach and link model - Targets metropolitan and regional reaches (at least 80 km) over DWDM systems.
- Interoperability features - Addresses forward error correction (FEC), Physical Medium Dependent (PMD) sublayer behaviors, and compatibility with DWDM black‑link environments.
- Energy and operational considerations - References Energy‑Efficient Ethernet (EEE) and management implications for long‑haul coherent links.
Note: this content reflects the amendment’s scope as published; implementers should consult the complete text for exact protocol parameters, management object identifiers, and compliance test procedures.
Practical applications
- Upgrading metro/regional transport networks to native 100 GbE over operators’ DWDM infrastructure.
- Enabling carriers and service providers to offer long‑reach Ethernet services (100GBASE‑ZR class deployments) across existing optical transport systems.
- Integrating coherent 100 Gb/s optics into data center interconnects (DCI) where DWDM aggregation and 80+ km reach are required.
- Designing interoperable DWDM transceivers, line systems and network management systems that support standardized management parameters and link behaviors.
Who should use this standard
- Network equipment vendors (optical transceivers, switches, ROADMs)
- System integrators and solution architects for metro/DCI/WAN networks
- Network operators and carriers planning 100G Ethernet over DWDM
- Standards engineers, test labs and compliance bodies
