China Direct Modulation Video Audio Transmitter Optical Transmitter with AGC, Find details about China Optical Transmitter, Video Audio Transmitter from Direct Modulation Video Audio Transmitter Optical Transmitter with AGC
Dual module RF driver, highefficiency laser pre-distortion adjustment.
Full-automatic OMI control, AGC &MGC:
Under AGC status, inputlevel is between 78~88dBuV,and system index is optimum.
Under MGC status, input range can be adjusted between 75~90dBuV by theATT on front panel.
Built-in dual backup powersupplies; switch full-automatically.
One is working, with the other as coolbackup (suggested).
Both are working at the same time, withone as hot backup. If one is damaged, it will switch to the otherfull-automatically. Switch time≤10us.
DualRF input port:
1. AMinterface: Input 59routes PAL-D(47-550MHz).
2. Digitalinterface(-10dB): Input digitalvideo(550-750MHz).
