6500 Reconfigurable
Line System

6500 RLS 635x284 comp

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 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. 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. And with the 6500 RLS, increasing fiber capacity with the L-band is just as easy as lighting the C-band—you get double the capacity with no surprises and no impact to existing C-band traffic.


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

6500 RLS integrated C&L-band architecture

With Ciena’s integrated C&L-band solution, adding wavelengths to the L-band is just as easy as lighting the C-band.  You get double the capacity, with no headaches. No complex re-engineering or re-balancing of the line system.  And most importantly, no impact to existing C-band channels.
