1.2GHz Dual Forward Optical Transmitter


ACI’s A8KFT3UD-1550nm is a head-end 1.2GHz dual forward optical transmitters (Tx) for HFC or FTTH applications. The A8KFT3UD-1550 Tx has two transmitters integrated in one module which can transmit RF signals over a fiber length up to 30km. This compact and cost effective Tx module is 3RU in height and up to 12 Tx modules(i.e. 24 transmitters) can be integrated in the 19-inch high-density chassis (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.
