Product overview

The 6500-S32 supports sustainable OTN network evolution, with muxponder card-based OTN switching and control plane automation, using the high-capacity 1.2T OTN switch-on-a-blade module. This flexibility allows efficient scaling of OTN switching capacity up to 4.8T per 6500-S32 and modernization of your network with a power- and space-optimized OTN switching solution. Various line and equipment protection options are available, including common equipment redundancy, enabling a range of differentiated service offerings for increased network availability.

The 6500-S32 supports the complete suite of photonic architectures, including colorless-directionless-contentionless (CDC) and flexible grid ROADMs, for the power to dynamically send any service anywhere in the network. A full range of wavelength selective switch (WSS) cards and filters provide optimized performance and cost for various degree-branching sites.

Allowing you to continually get more from your network investment, the 6500-S32 can be tailored to cost-effectively address applications from 100G to 1.6T DWDM with market-leading coherent innovations. Ciena's WaveLogic 6 Extreme (WL6e) technology offers programmable line rates from 200 Gb/s to 1.6 Tb/s, enabling single-carrier 1.6 Tb/s wavelength transmission and thereby supporting 800G networking across long links. The WL6e 1.6T MOTR card is compatible with all 6500 D-Series and S-Series shelves, facilitating seamless technology upgrades. Ciena's market-leading WaveLogic 5 (WL5) coherent technology is optimized for efficient transport of 100G/400G client traffic. WL5 is offered on the 6500 with programmable 800G performance optics in the WaveLogic 5 Extreme (WL5e) 800G MOTR card and WaveLogic 5 Nano (WL5n) 400G Coherent Pluggable Transceivers across various interfaces.

To help you sustainably evolve your OTN network, the 6500 D/S-Series offers modular, compact OTN switching that significantly reduces space and power requirements. The high-capacity 1.2T OTN switch-on-a-blade is a two-slot module that can be deployed across any 6500 D-Series or S-Series shelf. This flexibility allows you to efficiently scale capacity up to 4.8T and modernize your network with right-sized OTN switching. These capabilities combine with subwavelength grooming to ensure the most efficient bandwidth utilization and scaling of the network.

Ciena's intelligent control plane allows the network to automate and distribute many functions formerly performed through a combination of centralized management systems and manual processes. Harness both photonic and OTN control planes on the 6500-S32 for several advantages, including:

  • Accurate inventory of equipment and bandwidth resources
  • Faster service provisioning and turn-up
  • Tunable SLAs through flexible protection and restoration options
  • Network optimization and maintenance

Additionally, Ciena's Navigator Network Control Suite® (Navigator NCS), powered by Navigator Multi-Layer Controller (Navigator MC), simplifies and automates lifecycle operations across Ciena's packet and optical infrastructure, spanning access, metro, core, and subsea domains. It synchronizes operations across network layers for efficient service creation, activation, and troubleshooting. Navigator NCS offers a unified GUI and open REST APIs for seamless integration and workflow automation, supported by Ciena's Emulation Cloud for continual API testing.

The 6500-S32 is part of the 6500 family, which offers various chassis form factors to provide flexible, cost-optimized configurations to best match site-specific requirements. Tailored for high-capacity applications, the 6500-S32 offers modular OTN switching with industry-leading coherent and control plane capabilities, enabling cost-effective delivery of a flexible range of services across the network.
