Description
The A1751A laser module is a dense wavelength division multiplexing (DWDM) laser for analog applications. It features a distributed-feedback (DFB) chip that has been designed specifically for radio frequency (RF) applications. The A1751A 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 the quadrature amplitude modulation (QAM) channels.
Wavelength-division multiplexing is being designed into cable television architectures. DWDM, a method for delivering targeted QAM signals to different locations, allows multiple signal sets to be combined onto a single strand of fiber for transmission from a head end to a hub. At the hub, individual QAM signals can be selected and combined with broadcast analog channels. The versatile A1751A DWDM laser module reduces cable network architecture fiber needs and lessens equipment requirements in the hub.
The A1751A is available in a wide range of standard ITU wavelengths. The lasers are offered as either for ward-path (40 MHz—860 MHz) or return-path (5 MHz—210 MHz) modules.Features
