C-COR.net will demonstrate its end-to-end fiber optic transport package, including headend-to-node narrowcast products and node-to-headend digital return technology, at the May 2001 SCTE (Society of Cable Telecommunications Engineers) Cable-Tec Expo (Booth No. 384) in Orlando, Florida.
The demonstration will feature the Company's new lumaCOR system of modular, high-performance optical communications products that includes the 1550 nm externally modulated optical QAM transmitter providing forward path narrowcasting, digital injection, and transmission at ITU-grid wavelengths. The electro-absorption modulated QAM transmitter offers an alternative to higher-priced Mach-Zender external narrowcasting and service-based transmitters.
C-COR.net's active demonstration will feature the 1550 nm optical Erbium Doped Fiber Amplifier (EDFA) that provides superior noise figure and gain flatness over a wide range of optical wavelengths and optical input powers. Transmitters and passive optics components that are custom-designed for Return Path DWDM (Dense Wavelength Division Multiplexing) implementation will also be components of the network demonstration.
The node end of the demonstration will present two digital return solutions from C-COR.net: digital summing using transceivers and two-to-one muxing. For the first solution, C-COR.net's mini Fiber Node (mFN) will utilize the Company's Digital Return Transceiver (DRTR) to provide digital daisy-chain summing and local full duplex "Fast Ethernet" functionality. The Ethernet feature adds local-node-area, high-speed data capacity to HFC (Hybrid Fiber Coax) networks.
C-COR.net's second digital return solution uses the Navicor Quadrant Node with Digital Time Division Multiplexing to combine two independent 5-42 MHz return path links onto one 1550 nm ITU digital laser module. This solution doubles the return capacity per wavelength of each transmitter.
C-COR.net will also display the Navicor Line Extender, Navicor FlexNet Node, and FlexNet 900 Series Trunk/Bridger, all incorporating the C-COR net's TL (Transfer Linearization) Technology. TL Technology improves the linear characteristics of standard, highly reliable silicon technology hybrids, resulting in higher operating level capabilities and/or improved distortion performance, higher channel capacities, and improved system level performance. C-COR.net will also be showing the new Navicor QuadrantIII NQ4 Series Node with full forward and reverse segmentation.
