OVERVIEW:
The VidOptic FCT-2500 is a direct modulation 1550nm DFB transmitter for analog TV, digital TV and CMTS signals local fiber dense distribution and QAM TV Signal long-distance fiber transmission. The transmitter utilizes high linearity DFB laser, RF power digital automatic process technique, along with RF pre-distortion circuit developed by Vidovation. The built-in microprocessor monitors the transmitter working status and automatically ensures the optimistic performance. The VidOptic FCT-2500 is ideal for analog TV fiber distribution within 20km and QAM TV signal long distance transmission within 100km.
