1751A 1550 nm DWDM DFB Laser Module
The 1751 laser module is a Dense Wavelength-Division Multiplexing
(DWDM) laser for analog applications. It features a distributed feedback
chip that has been designed specifically for Radio Frequency (RF)
applications. The 1751 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
versatile 1751 laser module reduces cable network architecture fiber
needs and lessens equipment reqirements in the hub.
