The CN 4350 Ethernet Services Provisioning switch combines IEEE 802.1Q Ethernet Bridging with carrier-grade reliability, performance, and management capabilities for deployment in service provider residential and commercial triple-play networks. The CN 4350 system is a NEBS 3 and ETSI-certified ten slot chassis with redundant common equipment. Major CN 4350 components include the 160 Gb/s Fabric and Control module (PFX-80), 10 port 1 Gigabit Ethernet Module (PSC1), and 1 port 10 Gigabit Ethernet Module (PSN10). The PFX80 provides non-blocking connectivity between all 8 interface module slots. Each interface slot can be populated with any mix of PSC1 and PSN10 modules-supporting up to 80 full duplex Gigabit Ethernet or eight 10 Gigabit Ethernet ports. The PSC1 and PSN10 support pluggable optics, SONET-like performance monitoring, packet processing, and embedded signaling and control channels.

Flexible and Cost-effective 10 GB/S Ethernet Transport and Connectivity
The CN 4350 PSN10 can be provisioned to support 10 GbE LAN or WAN through 850nm and 1310nm XFP optics and as an OTU-2 (ITU G.709) interface to carry 10 Gigabit Ethernet over 46 channel DWDM optics. A transponder-only option-allowing a single-card solution to transport 10 Gigabit Ethernet LAN/WAN in a DWDM network-is also available. The combination of transport optics and higher layer packet switching of the CN 4350 delivers a powerful solution unmatched in today's 10 Gigabit Ethernet switching market.

Guaranteed Bandwidth and Low Deterministic Latency
The CN 4350’s high-performance switching—enabled by Ciena’s unique VirtualWire™ VLAN technology—provides guaranteed bandwidth and low deterministic latency and jitter. Support for 4096 VLANs per interface allows scalable connectivity between network devices. VirtualWire VLANs enable port trunking, cross-connecting, and switching with TDM-like performance. Support for QoS with up to eight classes of service—including two priority queues for VoIP and video traffic—ensures zero contention among services with strict subscriber segregation and service level agreements.

The CN 4350 also provides 100% line utilization without packet loss and controlled switchover and upgrades. Management and configuration options for the CN 4350 include SNMP, CLI, HTTP, and the ON-Center® Network Control System.
