Coherent ELS

Delivering scale and high-capacity coherent DWDM to the edge in a compact, hardened form factor with unprecedented operational simplicity

ELS 10 and 48ch 2000x500

With Ciena’s Coherent ELS, network providers can benefit from a coherent-optimized open line system (OLS) that is purpose-built to fully address next-generation edge network requirements today and moving forward. The ELS cost-effectively delivers 100G to 400G coherent DWDM wavelengths to the edge, enabling a full system capacity of up to 48 channels for point-to-point applications or up to 42 channels for linear and hub/spoke applications.

A key differentiation of Ciena’s Coherent ELS is the built-in software intelligence and automation that facilitate deployments, accelerate turn up, and optimize system performance—enabling a new operational paradigm for photonics at the network edge.

Features and benefits
