OpVista Debuts WaveGrabber Optical System for MSOs

OpVista, a start-up based in Irvine, California, unveiled a new optical transport system designed to provide cable operators with greater wavelength management capabilities. Whereas conventional optical transport architectures use fixed lasers, optical switches and ADMs to transmit multiple wavelengths over the cable network, OpVista's WaveGrabber technology broadcasts all wavelengths throughout the network to all available hubs. At each hub, a tunable receiver is remotely and instantaneously tuned to the desired wavelength. As little as a single Gigabit Ethernet (GigE) can be dropped and optical power balancing is automatic. OpVista also features a proprietary WaveMultiplier technology that carries four wavelengths per single 50 GHz ITU window, multiplying capacity eight times over conventional systems. The company said its Ultra-DWDM signal can travel 1000 km without regeneration or dispersion compensation and a single fiber can now carry up to 640 Gigabit Ethernet streams. Trials are underway.
