The 1751A 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 1751A 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 1751A laser
module reduces cable network architecture fiber needs and lessens equipment
reqirements in the hub.
The 1751A is available in a wide range of standard ITU wavelengths. The lasers
are offered as either forward-path (40 MHz-1 GHz) or return-path (5 MHz-210
MHz) modules.
