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.
