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.
