Description

1550nm DFB laser Modules is a Dense Wavelength-Division Multiplexing (DWDM) laser for analog applications. It features a distributed feedback 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 narrow transmitter designs. It also features low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The lasers 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.

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.
