Z-Series Packet-Optical

Cyan Z77

The Z77 is Cyan’s flagship packet-optical transport platform (P-OTP) optimized for metro and regional core and hub deployments. The Cyan Z77 introduces transformational scale by supporting up to 200 Gbps of capacity per slot and 2.8 Tbps per chassis. At just 13RU in height, the 14-slot Cyan Z77 chassis combines massive capacity with modular functionality at a fraction of the cost of prior generation systems.


  • Scalable P-OTP optimized for metro and regional core and hub deployments
  • Modular system supports plug-and-play Carrier Ethernet 2.0, wavelength, OTN, and SONET/SDH
  • Non-blocking architecture integrates 100 Gigabit Ethernet (100GbE) packet, 100G coherent transport, and 96-channel 100G ROADM – scaling to 2.8 Tbps/shelf and greater than 10 Tbps/fiber
  • Comprehensive optical multiplexing, transponding, muxponding and ROADM options simplify the transition from 10G to 100G coherent transport
  • Multi-layer switch-fabric supports high-performance 1/10 GbE and 100 GbE switching up 4.2 billion pps (full line-rate concurrently across all ports) and OTN services
  • Connection-oriented Ethernet (COE) ensures more manageable, resilient and predictable Ethernet transport
  • Carrier-grade design provides no single point of failure and supports hitless upgrades
  • Complements Cyan’s Z33, Z22, and Blue Planet to provide a cohesive solution extending from the edge to the core

High-capacity, Flexible Design

As a key component of an end-to-end Z-Series solution for metro and regional networks, the Z77 supports the same Ethernet, wavelength, OTN, and SONET/SDH service modules as the Cyan Z33 and Z22.

The Z77 also expands the functionality and scale of the Z-Series to support fully non-blocking cross-connection of Ethernet and OTN services with the XC-2800 multi-layer switch-fabric. Working in unison with a new family of high-performance service interface modules, the cross-connect fabric enables the Z77 to provide high-density aggregation of 1/10 Gigabit Ethernet (GbE), 100 GbE, and ODU-4 services, and play a key role in networks that historically required large routers frequently costing an order of magnitude more than an equivalent Z-Series solution.

100G Packet + Optical Industry-First

The scalable Z77 platform converges 100GbE packet switching and transport, 100G coherent optical transponding and muxponding, and a 96-channel ROADM capable of transmitting 10 Tbps on a single fiber. Unlike competitive solutions, this means service providers and data center operators are assured that a single platform will satisfy all requirements for inter-connecting packet and optical networks at 10G and/or 100G rates, while aggregating and transporting wavelength and Ethernet services with optimal efficiency. As an added benefit, the Z-Series 100 GbE packet, 100G coherent transport, and 96-channel ROADM modules support single-slot designs and pluggable CFP and SFP interfaces to ensure space-savings and flexible connectivity.

Carrier Ethernet 2.0

The Z-Series CE 2.0 solution offers a compelling alternative to traditional Ethernet switching and routing architectures for the aggregation and transport of Ethernet services. Cyan’s Z-Series was among the first products to achieve CE 2.0 certification from the Metro Ethernet Forum (MEF), ensuring that the platform enables cost-effective Ethernet service delivery with carrier-grade capabilities such as QoS, scalability, reliability, and service management. Beyond CE 2.0, the Z-Series platforms deliver non-blocking, line-rate 1/10 GbE and 100 GbE switching, as well as standards-based COE to provide more resilient and predictable Ethernet transport. These enhancements overcome the performance limitations found with traditional layer 2/3 Ethernet solutions, allowing network operators to build cost-efficient, performance-assured networks optimized for the delivery of deterministic E-Line, E-LAN, E-Tree, and E-Access services. The Blue Planet SDN platform further enhances the solution with A-to-Z multi-vendor provisioning and end-to-end circuit visualization to simplify service orchestration and ongoing network operations.

Cyan Blue Planet and Z-Series

Cyan Blue Planet software provides open, multi-vendor orchestration for multiple layers across the WAN and naturally provides excellent element-, network- and services-level management for Z-Series packet-optical transport platform (P-OTPs). Customers use Blue Planet software for multi-layer visualization of end-to-end network connections. Planet Design enables you to see performance, scalability, and resiliency implications while in the network design phase. Planet Operate provides 3D multi-layer network status and relationships between fibers, wavelengths, and any associated aggregation and service layers as well as integrated multi-vendor, multi-domain orchestration. Planet View provides multi-layer performance monitoring and SLA assurance. Planet Inventory provides full-featured asset and circuit inventory reporting and verification capabilities. Finally, Blue Planet's suite of open, northbound APIs transform Z-Series P-OTPs into a dynamic and agile network, where services and infrastructure are controlled as programmable resources.
