The 1754C laser component 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 component 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.
