AOT-03-1550
1550nm Direct Modulation DWDM Optical Transmitter
AOT-03-1550 adopts a high performance 1550nm DFB laser with optional Dense
Wavelength-Division Multiplexing (DWDM). Combined with ACE® patented full
frequency pre-distortion circuit, it features low adiabatic chirp to maximize
signal quality in short and long lengths of fiber, and excellent inherent linearity
to minimize degradation of the broadcast signals caused by QAM channels
AOT-03-1550 supports standard ITU wavelengths. It reduces cable network
architecture fiber needs and lessens equipment requirements in the hub.
