CATV 1550nm Directly Modulation Fiber Optical Analog Digital TV Transmitter
CATV 1550nm Directly Modulation Fiber Optical Analog Digital TV Transmitter
Description :
DMTX optical transmitter is designed according to CATV standard. It modulates CATV RF amplitude signal into 1550nm optical signal, and then transmits it to optical node in HFC network through single-mode optical fiber. It is mainly used for TV signal medium-sized network transmission and can be used for many purposes. The high-power optical amplifiers are used for the laying of fiber-to-the-home (FTTH) networks.
DMTX optical transmitter is equipped with a reliable and stable optical output power circuit and a pump laser thermoelectric cooler temperature control circuit to ensure the best performance of the equipment. Professional cooling structure design, intelligent temperature control fan, low power consumption. It is an ideal choice for building CATV secondary network signal transmission.
