ND-1103 SDI Repeaters is a HD SDI repeater for transmission distance extension. Supporting 14 HD formats as SMPTE-292M (1.485Gb/s, 1.485/1.001Gbps), the SD-1645 re-clocks the input signal and distributes two channels. The transmission distance is easily extended 300ft per each box. Many remote demands have been met by this great tool for needs in very remote locations or event transmissions. When you see this great tool you will be amazed by the solution it will provide to your long transmission needs. Extend HD CCTV links up to 1.0km with power over cable and camera control link over single coax cable. Each unit receives a HD-CCTV signal that may be attenuated by up to 200m of coax cable.
The repeater contains three critical components to correct and then retransmit the signal:
◆Adaptive Equalizer to return the signal to its original amplitude and modulation.
◆Reclocker to resynchronize the signal-bringing it back to its original condition.
◆Cable Driver to retransmit the signal with its original charac teristics restored.
Furthermore, the repeater design allows for two
unique benefits:
◆Power can be transmitted from the recorder side to the camera over the coax cable.
◆Up to 6 repeaters may be powered from the coax cable; if one or two repeaters are used, the power may also be adequate to power the camera.
◆A control signal (RS485) can be transmitted from the recorder side to the camera over the coax cable.
