![]() The new product also features high port density and easy upgrading of transmission capacity on a module basis so it saves initial cost and operating cost. It provides the flexibility to be adopted to any network topology and STM-1(155M) /STM-4(622M) multiplexing. The compact - 88 (H) x 482 (W) x 300 mm (D) - low-power SpectralWave C-Node is positioned as an entry model to next-generation SDH/SONET. The new system is part of the company's metro network system product line, which ranges from the next-generation SDH/SONET "SpectralWave U-Node," Gigabit-Ethernet multiplexing system "SpectralWave MG Series," metro WDM "SpectralWave MW Series," and metro multi-service platform "SpectralWave MMSP Series." NEC will start delivering the product in July 2002 and expects to sell 30,000 systems in the first 3 years. The SpectralWave C-Node will dramatically save space and cost, according to the company.
