1550nm DFB Laser Chip with Butterfly Package Standard ITU Grid Wavelengths
1550nm DFB laser Modules is a Dense Wavelength-Division Multiplexing (DWDM) laser module for analog applications. It features a distributed feedback laser chip that has been designed
specifically for Ratio Frequency (RF) applications. The laser module has a wide temperature range for reliable performance in harsh node environments and narrowband 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 laser module reduces cable network architecture fiber needs and lessens equipment requirements in the hub. The 1550nm DFB laser Modules is available in a wide range of standard ITU
wavelengths. The lasers are offered as either forward-path (40MHz – 860MHz) or return-path ( 5MHz– 200MHz) modules.
