WaveLogic 5 Nano

Smaller footprint. More applications.

Trusted WaveLogic™ technology. Now in pluggable form.

Reduced power consumption. More high-capacity connectivity.

Whether you need to upgrade to higher data rates at the edge of your network, modernize your existing optical systems, efficiently increase bandwidth between data centers, or migrate your metro-regional network to a converged IP/Optical infrastructure, you can benefit from the modularity, versatility, and scalability of WaveLogic 5 Nano pluggable coherent optics.  Learn more about how you can sustainably evolve your edge, DCI, and metro-regional networks.

WaveLogic 5 Nano: Addressing sustainable network evolution with use-case optimized pluggable optics

Evolve to a fully disaggregated network architecture via a multi-vendor pluggable optics ecosystem

Open networks are underpinned by optical interconnect standards where Ciena is an active leader in driving global efforts. With WL5n Standard QSFP-DD and CFP2-DCO transceivers, you can upgrade your network while relying on a full range of interoperable specifications.

Optimize your network efficiency and performance for metro-regional ROADM applications

Looking to reduce energy consumption and transport costs in your optical network? Are you evaluating converging IP and Optical layers? WL5n Enhanced QSFP-DD and Universal QSFP-DD and CFP2-DCO transceivers deliver maximum performance and flexibility all at lower power and cost per bit than previous 100G-400G coherent technologies. You can choose from the widest pluggable feature set in the industry, including: packet and OTN transport, maximum reach with pluggable optics, support for high span-count ROADM architectures, compatibility with any photonic line system, and the ability to deploy in brownfield environments.

Ciena offers all consumption models for pluggable coherent optics. WL5n is supported across a wide range of Ciena transport and routing and switching platforms as well as select third-party host platforms.
