The HKD-LT1310/3000 optical transmitter is designed according to the CATV standard. It modulates the CATV RF amplitude signal into 1310nm/1550nm optical signals, and then transmits them through single-mode optical fiber to the optical nodes in the HFC network. It is mainly used for medium-sized network transmission of TV signals and can be combined with multi-port high-power optical amplifiers for the construction of fiber-to-the-home (FTTH) networks. The LT3000 optical transmitter is equipped with a reliable and stable optical output power circuit and a pump laser thermal electric cooler temperature control circuit to ensure the best equipment performance. The professional heat dissipation structure design, intelligent temperature-controlled fans, and low power consumption make it an ideal choice for building CATV secondary network signal transmission.

We have selected high-performance DFB lasers from internationally renowned brands. These lasers feature narrow spectral lines, excellent linearity and high output power.

The advanced multi-frequency point radio frequency pre-distortion technology is adopted. The driving circuit employs radio frequency power automatic processing technology, which can automatically optimize the driving level, ensuring that the C/CTB, C/CSO and C/N indicators always remain at the optimal values.
