EtherBurst ™ PX-1000
Photonic Node

Driving Ethernet efficiency into optical networks

EtherBurst, with it's vmSwitching™ capabilities, forms a distributed layer-2 Ethernet switch comprised of PX-1000 Photonic Nodes and SX-1000 Ethernet Service Nodes. PX-1000 Photonic Nodes are deployed in a metro ring, and provide fully automated optical amplification and power management of the photonic layer.

PX-1000 Features

The PX-1000 Photonic Node is a modular component of the EtherBurst optical switch. Each PX-1000 Photonic Node connects multiple SX-1000 Ethernet Service Nodes to the photonic layer. Up to thirty-two SX-1000 Ethernet Service Nodes may be connected to a metro ring of PX-1000 Photonic Nodes.

Matisse optical amplifier (MOA) module
The PX-1000 Photonic Node supports Matisse optical amplifier (MOA) modules. Each MOA module supports connectivity for SX-1000 Ethernet Service Nodes on a single ring.

MOAs enable SX-1000 Ethernet Service Nodes to be added to a network without affecting traffic from existing SX-1000s.

Optical supervisory channel
Every PX-1000 Photonic Node and SX-1000 Ethernet Service Node includes an optical supervisory channel (OSC). The OSC is used to manage communication between the PX-1000s and SX-1000s on the ring. The OSC also provides efficient layer-2 multicast service delivery, especially important in IPTV broadcast services.

Dual AC or DC power supplies
Each PX-1000 supports redundant, hot-swappable AC or DC power supplies.

PX-1000 Benefits

Maximum utilization of optical bandwidth
Each PX-1000 Photonic Node supports up multiple SX-1000 Ethernet Service Nodes through MOA modules. SX-1000 Ethernet Service Nodes are colorless and assigned a destination color by the MOA port. As SX-1000s are added to the network all nodes are auto-discovered and immediately available through MatisseView for Ethernet service provisioning.

Increased service flexibility
The PX-1000 Photonic Node is an all-optical system which automatically manages the power and signal quality of the photonic layer. Since there are no optical-electrical-optical (OEO) conversions, there is no OEO transit tax, which can waste as much as 50% of optical network bandwidth.

PX-1000 Photonic Nodes are transparent to Ethernet services, and require no operator intervention to accommodate changing metro traffic patterns.

Lowest total cost of ownership
A recent study by Network Strategy partners shows that EtherBurst delivers the lowest total cost of ownership for metro packet optical transport networks, offering both capital and operational expense savings of 50% when compared with ROADM solutions. The compelling economics of optical burst switching combined with the operational simplicity of the EtherBurst optical switch result in the lowest cost of ownership when scaling metro and campus networks beyond 10 Gbps.
