Cyan Further Simplifies Network Scale and Operations With Its New Single-Slot ROADM Module

Fully-Integrated, Single-Slot "ROADM on a Blade" Enables Easy Upgrades for up to 40 10G Channels of DWDM With "Point and Click" 10G Wavelength Provisioning

PETALUMA, CA--(Marketwire - September 21, 2010) -  Cyan today announced the addition of a new, highly-integrated, reconfigurable optical add/drop multiplexer (ROADM) module with up to 40 channels of wavelength selectable switching (WSS) for use in Cyan Z-Series platforms. The new Z-Series WSS-402 module simplifies the upgrade of fiber transport routes for up to 400 Gbps of capacity per-fiber with simple plug and play modules, and optional fixed or tunable optics. Backed by the revolutionary CyMS multi-layer management system, Z-Series customers benefit from network-wide, simple point and click A to Z provisioning of wavelengths on demand. The new single-slot design now adds full ROADM functionality to Cyan Z33 and Z77 platforms.

"The new Cyan Z-Series WSS-402 module makes it easier than ever for us to incrementally scale network capacity, when and where needed," said John Greene, Chief Network Engineer at Great Plains Communications. "We deployed Cyan's Z33 and Z77 platforms to support 10 Gigabit Carrier Ethernet, wireless backhaul, as well as existing SONET/SDH and wavelength services. Our recent deployment of the new WSS-402 module in our Z-Series network confirmed that we can readily add further network capacity and wavelength switching for current and future services. Collectively, Cyan's Z-Series solutions have enabled us to roll out new services to increase revenues, while simultaneously reducing the cost of capacity for greater profitability."

WSS-402 Relieves Pressure of Compounding Traffic Scale; Adds Optical Switching

Service providers globally are experiencing unprecedented increases in network traffic, often requiring the need for higher capacity dense wave division multiplexing (DWDM) transport. Initially, this technology was used in the network core and very high density metro-core markets. However, continued scaling of traffic is now consuming available fibers across metro and regional networks, creating the need for DWDM more pervasively across the network. Service providers have two choices: either add more fiber, or use DWDM to combine multiple wavelengths of transport services per fiber.

Cyan's Z-Series platforms support Carrier Ethernet services with connection oriented Ethernet transport, SONET/SDH transport, as well as G.709 muxponded and transponded services. As services consume available fibers, service providers have a choice of adding four, eight or up to 40 channels of DWDM capacity with simple card additions. Cyan's new single-slot WSS-402 module provides a fully integrated design providing DWDM, EDFA (Eridium Doped Fiber Amplifiers), OSC (Optical service channel) and WSS all in one single-slot module. This represents one of the most highly integrated solutions in the market, making it easy to add 40 channels of capacity, with two degrees of wavelength selectable switching ROADM functionality for even greater efficiency and economics.

"Service providers' networks continuously grow in scale and complexity," said Eric Clelland, co-founder and vice president of sales for Cyan. "Our new single-slot WSS-402 module provides a simple plug-and-play approach to enable powerful wavelength selectable optical switching across regional, metro and edge networks with powerful new economies. The physical elegance of this highly-integrated design, combined with the operational simplicity of CyMS-enabled A to Z, point and click provisioning of wavelengths and associated services across the network, makes service capacity expansion easier than ever."

The new Z-Series WSS-402 uses just one slot and is interchangeable for use in both Cyan Z33 and Z77 platforms. An associated Cyan AWG-40 (array wavelength grid) provides convenient optical interconnect access for up to 40 wavelengths of drop and insert traffic. The systems support fixed and tunable optics for maximum flexibility.
