The Grass Valley™ LDK 4425 3G fiber power converter is a heavy duty, high-quality, multi-standard module that converts 2X single mode (dark) fiber signals to full 3G camera-powered SMPTE hybrid fiber. It supports all HD video formats and is part of the versatile Grass Valley 3G Transmission family. Using this converter, with the 3G Twin Base Station (LDK 4420) installed in the truck, can achieve very long cable runs using 2X single mode fiber cable. Connecting the LDK 4425 to a local mains power supply converts the 2X single mode fiber signal into a full SMPTE hybrid fiber connection ready to power a Grass Valley LDK 3G Fiber camera.
