1752A 1550 nm DOCSIS 3.1 DWDM DFB Laser, CATV Application

The 1752A is a Dense Wavelength-Division Multiplexing (DWDM) laser module that is fully DOCSIS 3.1 compliant and can support operational bandwidth of up to 1.2 GHz. The 1752 laser platform has been designed specifically for CATV applications with a wide operating temperature range for reliable performance in harsh node environments and narrow linewidth transmitter designs. The 1752A DOCSIS 3.1 DWDM DFB laser module 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 1752A laser module reduces cable network architecture fiber needs and lessens equipment requirements in the hub.
