The DWDM DFB Butterfly analog Laser Diode For CATV Application is a Dense Wavelength-Division Multiplexing (DWDM) laser for analog applications. It features a distributed feedback chip that has been designed specifically for Radio Frequency (RF) applications. The DWDM DFB Butterfly analog Laser Diode has a wide temperature range for reliable performance in harsh node environments and narrow transmitter designs. It also features low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The laser’s excellent inherent linearity minimizes degradation of the broadcast signals caused by quadrature amplitude modulated (QAM) channels. The versatile DWDM DFB Butterfly analog Laser Diode reduces cable network architecture fiber needs and lessens equipment requirements in the hub.
