6500 Reconfigurable Line System

If you’re a network operator trying to manage bandwidth-intensive applications—like connecting data centers, increasing capacity on submarine cables, or building out 4G/5G wireless infrastructures—your network must be ready to adapt to changes. You need to get more out of your photonic line system. More scale. More density. More programmability. All while taking up less space.

The 6500 Reconfigurable Line System (RLS) is a compact, simple-to-deploy, photonic layer solution that improves scalability, reduces footprint, and offers more flexibility and programmability. You can quickly react to unpredictable traffic requirements by easily scaling nodal connectivity and wavelength add/drop capacity with its highly dense ROADM and amplifier configurations. And with 6500 RLS, increasing fiber capacity with the L-band is just as easy as lighting the C-band—you get double the fiber capacity with no impact to existing, in-service C-band traffic.

Features and benefits

  1. Automate optical networking through a modern photonic line software architecture designed for deployments at scale

  2. Access full efficiency benefits of the optical layer with operational simplicity and predictable performance

  3. Efficiently scale to meet your highest capacity network requirements with an optimized, ultra-dense photonic layer

  4. Conserve space by reducing footprint as much as 70 percent compared to traditional chassis-based systems, with a modular and compact form factor

  5. Simplify deployment, operation, and troubleshooting with built-in tools like Zero-Touch Provisioning (ZTP), network auto-discovery, and real-time network monitoring and visibility

  6. Double your fiber capacity with the simplest upgrade to L-band

Network applications
