TFT1550 Cable TV system1550nm Modulated O𒐪ptical Transmitter


Overview        Adopts standard 19 inch rack,TFT1550 is mainly used for indoor front-end progrജam transmission and image / voice signal transmission of any Hybrid fiber coax (HFC) system. Features         ● Advanced RF signal predistortion circuit design，ensure that the equipment can still 🍌 have excellent CTB and CSO indicators when the CNR value is high； 
        ●  ꦬ 45～862MHz or 45～1GHz downlink bandwidth；  🌌
        ●  ꧃ ဣ Superior SBS suppression design,provides longer transmission distance
        ● P𝄹ioneering adjustable SBS function ，provides more flexible configuration； 
        ● AGC design，stabilize output performance in different RF input🌌 level ranges，simplify  installation and operation program；
        ●  The built-in microprocessor provides excellent contro💖l performance and status display function.
        ● SBS modulated type is 13 to 19dBm（0.5dB step），whether the network architecture is combined with optical amplifiers for 100 km long-distance transmission or 65 km medium distance ring network, it can be adjusted by users according꧟ to the 🐠 application status, so as to reduce unnecessary expenses and reduce the risk of network architecture.
