CHICAGO -- RED-C, a maker of a comprehensive line of optical amplifiers, has presented its innovative Sentior product-line to form the fundamental building blocks for next-generation all-optical networks. By encompassing a closed spectral loop, RED-C's new Sentior line of products allows distribution of the optical physical layer's control functionality to the sub-system level and facilitates the incorporation of future optical elements within the network.

Being an essential consideration in WDM networks and highly dependent upon the characteristics of the network's optical components, the transmission spectral status must be monitored and analyzed at all times and a provision is made for alerts and correction measures when spectral failure is detected. Current EDFA designs, incapable of monitoring the spectral performance but designed rather for closing the gain-loop (optical power) only, require system management to constantly monitor and supervise all optical components incorporated along the transmission line, resulting in a heavy overhead burden as well as an intensive and complex management layer.

As it independently conducts the spectral monitoring and analysis, RED-C's Self-Managed EDFA, the Sentior 3550, substantially reduces management interference with the system's optical elements operation and thus much simplifies the management operation and structure and further eliminates most of its tasks associated with governing the optical physical layer.

Allowing the integration of all optical components within its mid-stage level, the Self-Managed EDFA eliminates their negative effect on system's OSNR and materially enhances system's reliability and survivability. RED-C's Sentior 3550 also reports to management the spectral status at each amplifier's output and thus eases installation, troubleshooting and re-configuration. It also eliminates the need for implementing OCM units within the network. RED-C's Self-Managed EDFA, evaluation prototypes of which are scheduled for September 2004, is to become a strong driver and enabler for locally distributed controlled systems, distinctive by the ease of their design and implementation, their enhanced performance and their reduced costs.

Being a corner-stone in next generation optical networks, the Self-Managed EDFA, is complemented with RED-C's newly released Sentior 9000, a Raman amplifier incorporating a line analyzing unit and a comprehensive eye-safety protection and the Sentior 2120, a cost-effective variable-gain EDFA based on a fixed gain, single stage, single pump EDFA capable of switching various saturable absorbers. Yossi Boker, CEO & Co-Founder, RED-C commented.

"RED-C's Sentior 3550 is an important step in making locally distributed controlled system a reality and a strong move toward the all-optical network vision. With its expanding product line, encompassing the Self-Managed EDFA, the low-cost variable-gain EDFA and the Raman amplifier, as well as its widely deployed high-end variable gain EDFA, RED-C provides its customer with the main building-blocks for designing and constructing most valuable and price competitive optical networks."

RED-C's team can be met at booth 10850, Supercomm 2004, 22 to 24 of June, McCormick Place, Chicago IL
