The five new optical products from JDSU are being developed based on a critical understanding of how Self Aware Networks of the future will operate. A major benefit the JDSU solutions will provide to network equipment manufacturers is the ability to design new networks that can automatically and dynamically reconfigure network traffic.
Self Aware Networks are needed to support the growing volume of high-bandwidth and unpredictable traffic as people and businesses increasingly use the Internet as a key utility in their daily lives for on-demand applications such as online video.
“Self Aware Networks require a new architecture and a new set of high performance, compact and cost effective components,” said Brandon Collings, Optical Communications chief technology officer for the CCOP segment at JDSU. “We’re developing a comprehensive portfolio of products that will enable these new architectures based on several years of collaboration with customers to understand the requirements of next generation networks.”
New JDSU Optical Products for Self Aware Networks
§ § Twin Wavelength Selective Switch (WSS) – Two independent 1x20 WSS’s integrated into a compact form factor to support the ‘route and select’ architecture at the heart of next generation networks. It will efficiently support rapid wavelength routing, improve signal isolation and reduce the amount of optical power lost at network switching nodes. It will also provide full Flexible Spectrum channel allocation and a graceful scaling for channel multiplexing and demultiplexing with colorless, directionless and contentionless capabilities.
§ § Dual Multi-Cast Switch – An integrated pair of new devices for Self Aware networks that implement colorless, directionless and contentionless wavelength routing in a single and highly compact and cost effective package. It will support up to 8 degrees of optical switching and 16 transceiver ports.
§ § Optical Channel Monitor – A high speed and high resolution channel monitor that has multiple inputs and a scanning filter to support the demanding needs of Flexible Spectrum and dynamically reconfigured Self Aware Networks.
§ § Hybrid Raman-Erbium Amplifier – An amplifier that re-energizes weakened network signals traveling over long distances while injecting less noise onto the network compared to conventional erbium doped fiber amplifiers (EDFAs). This will allow 100G or 400G signals to travel further with less performance degradation and leverages JDSU’s leading high power optical pump and EDFA technologies.
§ § EDFA Array – Several EDFAs integrated into a highly compact form factor will provide amplification within flexible multiplexing and demultiplexing modules.
Key Features of Self Aware Networks
§ § Colorless Capability – Allows for the selection of any wavelength (or color) channel to carry data along any available physical route within a network without any physical reconfiguration.
§ § Directionless Capability – Allows any wavelength channel to carry data along any physically available route within a network without any physical reconfiguration.
§ § Contentionless Capability – Removes the restriction that currently prevents multiple signals of the same wavelength traveling along different routes to be multiplexed and demultiplexed within the same add/drop module.
§ § Flexible Spectrum – Allows wavelength channels to be provisioned with various spectral widths providing the flexibility to support data rates beyond 100G that will require additional channel bandwidth compared to what is currently provided in today’s 50GHz channels.
