Specifications

Genuine Ciena 176-23A0-900 WL5N 200G/400G TYPE A.0 CFP2-DCO Coherent Optical Transceiver

The Ciena 176-23A0-900 is a WaveLogic 5 Nano (WL5n) Type A.0 CFP2-DCO coherent pluggable transceiver — Ciena's second-generation "Standard" DCO designed for multi-vendor interoperable metro and regional DWDM networks. Unlike direct-detect IM-DD modules, this coherent optic uses dual-polarization QPSK/8QAM/16QAM modulation with embedded DSP to transmit up to 400Gb/s on a single wavelength over standard C-band ITU grids. It supports 100G, 200G, and 400G line rates with programmable baud rates and Probabilistic Constellation Shaping (PCS), delivering carrier-grade reach from tens of km (DCI) up to 1000km+ with external EDFA amplification. Compliant with OpenROADM, OIF 400ZR/OpenZR+, and CMIS standards, it interoperates with Ciena 6500/5400/8192 platforms and qualified third-party router/line-system hosts. This is a coherent DCO module — it is NOT a direct-detect 100GBASE-LR4/ZR4 module and must be paired with a coherent-capable port on the far end.

Typical Applications

✅Metro & Regional ROADM Networks: Multi-span DWDM with flexible 50GHz grid and OpenROADM interoperability.

✅Data Center Interconnect (DCI): Point-to-point 400G ZR/OpenZR+ links up to ~40–80km unamplified, or extended reach (120km+) with EDFA line systems.

✅Converged IP-over-DWDM (IPoDWDM): Plugs directly into 400G coherent router ports (such as Ciena 8192 and qualified third-party host routers) for direct photonic-layer integration.

✅Legacy Network Modernization: Flexible 100G/200G/300G modes for seamlessly upgrading legacy DWDM systems to high-capacity coherent transport.

✅Carrier Multi-Service Aggregation: Simultaneous transport of 100GE, 400GE, OTU4, and FlexO client services over a single programmable wavelength.
