Applications
LT1300 optical transmitter is designed according to CATV standard. It modulates CATV RF
amplitude signal into 1310nm/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.
The LT1300 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
