CATV Indoor Transmitter 1310nm

LCT3DM is a cost effective CATV Tx designed for short and midrange transmissions, It is made by high linearity DFB laser , build-in pre-distortion adjustment circuit and laser APC, ATC closed loop control circuit. All the operating parameters are controlled by micro-processor, the LCD screen on the front panel can display relative operating status and the fault information.

 

  • Dual Module RF drive, high efficiency laser pre-distortion adjustment.
  • Full-automatically optical Modulation Intensity (OMI) coAntrol, AGC & MGC.
  • Under AGC status, input range is 78dBuV~88dBuV, system index is optimum.
  • Front panel has 20 grade OMI status display (Modulation Depth).
  • Dual power supply inside backup. Full-automatically switch.
  • Full-automatically control of casing temperature, ensure long life of the laser.
  • Automatic fan control when casing temperature reach 45℃,
  • When casing temperature reach 35℃, the transmitter will shut down automatically
  • Dual RF input port.
  • AM interface;Input 59 routes PAL-D (47-550MHz).
  • Digital interface (-10dB): Input digital video (550-750MHz). Time locked function.
