1.2GHz Forward Optical Transmitter


ACI’s A8KFT3U-1550nm is the head end equipment 1.2GHz forward optical transmitter (Tx) for HFC or FTTH applications. The A8KFT3 U 1550 Tx can transmit RF signals over a fiber length up to 3 0km. This compact and cost effective Tx module is a 3RU height and up to 12 Tx modules can be integrated in the 19 inch high density cha ssis (A8KMF3). The transmitter’s RF path employs several stages of RF amplification that includes single ended low noise high linear amplifiers and low noise push pull amplifier from G7/EU brand name vendors. The Transmitter’s adjustable OMI level and user defined AGC setting features make it very convenient in field application with a wide range of RF input loading from analog loading, analog and digital loading or full digital loading.
