1754C C-Band DWDM DFB Laser Module

DATASHEET | DECEMBER 2013

FIBER OPTICS

The 1754C laser module is a Dense Wavelength Division Multiplexing (DWDM) laser for analog CATV

applications. It features a distributed-feedback (DFB) device that has been designed specifically for

radio frequency (RF) and CATV applications. The 1754C 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 laser’s excellent

inherent linearity minimizes degradation of the broadcast signals caused by quadrature amplitude

modulated (QAM) channels.

The 1754C is available in all C-band ITU grid wavelengths.
