White CE2 MEF Certified Logo

The 6500 Family comes in multiple chassis form factors, from a compact 2RU, up to full rack sizes, with the ability to scale from 100 Gb/s to 500 Gb/s per slot. The smaller 6500-D2 and 6500-D7 offer both AC and DC power options, addressing a wide range of end-customer locations. The 6500-D2 extended temperature solution is also available for uncontrolled outside plant environments. A single software load and management system across the various shelves reduces standardization cycles and sparing expenses, and simplifies network operations.

Why 6500?

Future-ready scalability

Ciena's coherent interfaces give you a full suite of field-proven, plug-and-play high-capacity solutions for metro, long-haul terrestrial, and submarine applications. WaveLogic  programmable transceivers enable broader, more economical 100G deployments—with the ability to scale to 400G and beyond. And for securing every byte of your critical in-flight data, they also offer 100G/200G wire-speed encryption. An industry first!

More services, more business

The 6500's high-density 10G transponders enable multi-protocol, low-latency and wire-speed encryption capabilities to maximize your service revenue opportunities.

On-demand bandwidth

Our high-capacity wire-speed encryption modules complement high-capacity line rates with OTN switching to optimize bandwidth utilization and network efficiency. And they offer the added benefit of insulating your network against uncertain service mix by providing transparent transport of all client services.

Do more with less

Our L2 MOTR and eMOTR modules fully integrate packet switching within transport, providing sub-GE grooming for improved wavelength efficiencies and traffic prioritization for SLA adherence—so you can do it all with less equipment.

Programmable photonic foundation

Get the full range of photonic architectures, from Coherent Select for simple service extension to directionless, colorless, contentionless and flexible grid ROADMs for the power to send any service anywhere in the network, dynamically. And Smart Raman with PinPoint Advanced Fiber Analytics ensures unprecedented system and fiber performance.
