The VE883A is a True 4K HDMI Optical extender that consists of a transmitter VE883AT and a receiver VE883AR to transmit up to 4096 x 2160 / 3840 x 2160 @ 60 Hz (4:4:4) HDMI, audio, USB 2.0, IR, RS-232, and Gigabit Ethernet signals across 300 m (VE883AK1) or 10 km (VE883AK2) over a single duplex fiber optic cable losslessly. While helping avoid bulky cable setup, fiber optic cables are electrically isolated, thus they are immune to RFI and EMI. With ATEN’s exclusive FarSmooth technology, the VE883A prevents lagging and freezing by matching the output rates to the input rates and ensures that the video display is stable, smooth and identical to the source, particularly in long-distance extension applications where uninterrupted video streams are required.\nThe VE883A comes with interfaces of HDMI input / output, analog audio input / output, USB 2.0, IR, RS-232, and Gigabit Ethernet. Connectivity with USB peripherals is expanded thanks to the VE883A’s dual USB Type-A ports. For point-to-point extension, pluggable SFP+ modules are included to serve the purpose of optical connection. Plus, the VE883A is compatible with ATEN’s VM7584 / VM8584 Optical Input / Output Board installed in ATEN’s modular matrix switches to broaden applications. It is suitable for installations where True 4K video transmission across a long distance and electrical isolation are essential, such as control rooms, factories, and hospitals.
