Motorola introduced its enhanced coarse wavelength division multiplexing technology (E-CWDM), which the company said transmits multiple wavelengths on a single fiber, increasing the bandwidth up to five times, while extending the reach of CWDM by a factor of two.

By transmitting multiple CWDM optical signals over a single fiber optic connection, operators can segment serving areas into three, four or five discrete areas. With each optical signal carrying a full 1 GHz loading of broadcast and narrowcast content, over distances up to 25 kilometers between the hub and optical node, operators can meet the need for additional service capacity for HDTV, VoIP, VOD and high-speed DOCSIS services.
