The CN 5305 is a modular, chassis-based system optimized for metro-edge deployments in a wide variety of network topologies, including fiber and microwave rings, point-to-point fiber, microwave mesh, and fiber or copper to the subscriber. The switch supports high-density Gigabit Ethernet (GbE) connectivity to the subscriber edge and high-performance 10 Gigabit Ethernet uplinks to the metro core, with fully redundant commons and a distributed switch fabric for five-9s reliability and service continuity.

The CN 5305 is based on Ciena’s field-proven True Carrier Ethernet® technology, deployed by dozens of network operators in tens of thousands of points of presence, central offices, businesses, office parks, cell sites, remote terminals, and residences. It combines the low cost and high capacity of Ethernet with the reliability, management, and service quality usually associated with SONET/SDH networking systems. The CN 5305 software is based on an advanced service-aware operating system—used in all Ciena service delivery and aggregation switches—which provides consistent system and service attributes and a common operator interface, provisioning, and management capabilities. These features leverage customer investment in training and operational procedures, provide significant operational cost savings, enhance service creation velocity for faster time-to-revenue, and deliver synergy with Ciena’s best-in-class portfolio of right-sized service aggregation and service delivery Carrier Ethernet systems.

The CN 5305 incorporates the latest innovations in Ethernet switching technology and control plane protocols and utilizes high-performance programmable processors to deliver new features and functionality through simplified software upgrades with minimal disruption to customer traffic. This programmable architecture keeps capital and operating costs to a minimum and simplifies the migration to emerging standards and services, maximizing revenue potential and providing superior flexibility and investment protection.

The CN 5305 provides unparalleled support for carrier-grade MPLS/VPLS and Ethernet Layer 2 Virtual Private Networks (L2VPNs) thanks to a state-of-the-art feature set that includes sophisticated hierarchical Quality of Service (QoS), advanced Virtual LAN (VLAN) and virtual switching, comprehensive MPLS/VPLS/H-VPLS, resilient PBB-TE connection-oriented Ethernet, and robust Carrier Ethernet management and performance monitoring capabilities.

The CN 5305 is the only Carrier Ethernet switch in the industry to support interworking between Q-in-Q VLANs, MPLS/VPLS/HVPLS, and PBB-TE encapsulation formats. By enabling Ethernet and MPLS VPN and connectivity services to seamlessly traverse multiple domains and transmission facilities—each with its own encapsulation and transport—Ciena’s CN 5305 creates interworking functionality that supports complete service flexibility and maximum optimization of network resources and traffic engineering architectures.
