Coherent ELS

All products Ask the community

Ciena’s Coherent ELS is a coherent-optimized Open Line System (OLS) designed to meet next-generation photonic requirements at the network edge. ELS cost-effectively delivers 100G to 800G coherent DWDM, enabling a full system capacity of up to 28.8 Tb/s, with a minimal footprint and unprecedented operational simplicity.

Coherent ELS features and benefits

Coherent-optimized OLS

Delivers 100G to 800G coherent DWDM to the edge in a compact, hardened form factor across flexible configurations, including 400ZR and 400ZR+ applications.

Fast high-scale deployments

Eases deployments with a stackable plug-and-play design, automatic turn-up, and Low Touch Provisioning (LTP) along with flexible AC or DC powering to address specific site requirements.

ROADM-like operational simplicity

Provides integrated system intelligence and automation for faster service turn-up, troubleshooting, and real-time system optimization with a range of easy-to-manage options.
