CATV RF SYSTEM

CATV Transmitter 1310nm Outdoor Type

LCST3DM04

CATV & SAT IF Indoor Transmitter 1310nm - LCST3DM04

LCST3DM04 is a cost effective CATV & SAT IF Direct modulated Transmitter designed for short and mid range 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 microprocessor, 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°C,
  • When casing temperature reach 35°C, 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
