6500 Reconfigurable Line System

If you’re a network operator trying to manage bandwidth-intensive applications—like connecting data centers, modernizing MSO access networks, or building out 4G/5G wireless infrastructures—your network must become more adaptive. 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. It provides highly dense ROADM and amplifier configurations so you can quickly react to unpredictable traffic requirements by scaling nodal connectivity and wavelength add/drop capacity.

Network applications for the 6500 RLS:

Long-haul Data Center Interconnect (DCI)

  • Provides massive scale for the largest DCI deployments with optimized C+L-band architecture
  • Enables the best long-haul performance with Raman amplification
  • Is highly programmable with open APIs for network automation and simple OSS integration


  • Provides a simple deployment and operational model to ease installation and accelerate deployment velocity
  • Reduces footprint with highly dense, compact form-factors, providing scalability for small or large sites

MSO metro/access network modernization

  • Simplifies the transition to optical networking closer to the network edge
  • Enables massive scale to support a large quantity of add/drop wavelengths
  • Reduces footprint at hub and headend locations


Efficiently scales to meet the highest capacity network requirements with an optimized ultra-dense design

Reduces footprint by as much as 70 percent, compared to traditional chassis-based systems, with its modular and compact form factor

Eases deployment and operations with Zero-Touch Provisioning (ZTP), network auto-discovery, and full network visibility for simplified troubleshooting

Provides openness and programmability with a full suite of open APIs and a microservices-based software architecture

Unlocks double the fiber capacity with optimized C&L-band architecture
