in Harsh Environments

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.

The 1752A is available in a wide range of ITU grid wavelengths with industrial

temperature performance.
