Targeting CATV DWDM networks, K2 Optronics' 32-channel, 1550-nm wavelength, 1024-QAM lasers increase the digital capacity of QAM transmitters by up to four times to support the growing demand for interactive applications. At the same time, the lasers provide a twofold increase in the packaging density of QAM transmitters. K2 Optronics, www.k2optronics.com.
