The VE883 is a fiber-based extender designed to extend uncompressed 4K signal up to 300 m (using VE883K1) or 10 km (using VE883K2) over duplex fiber optic cables. The VE883 meets HDMI Specifications, including 3D, Deep Color (up to 12 bit), and signaling rates (up to 10.2 Gb) to ensure superior video quality. With ATEN's exclusive FarSmooth technology, the VE883 prevents lagging and freezing by matching the output rates to the input rates and ensures the video display is stable, smooth and identical to the source, particularly in long-distance extension applications where uninterrupted video streams are required. The VE883 features an HDMI input and output, analog audio input and output, USB2.0, IR, RS-232 control port, and a Gigabit Ethernet port. For point-to-point extension, the VE883 can receive fiber optic cables by inserting SFP+ modules to its optic port.1x VE883T 4K HDMI Optical Transmitter1x VE883R 4K HDMI Optical Receiver2x 0AD6-1F05-26EG Power Adapters2x Terminal Block 3 Pole2x Terminal Block 5 Pole1x 2XRT-0003G-1 IR Receiver1x 2XRT-0004G IR Emitter1x LIN4-0413-010G USB Cable2x 0X12-0017-700G HDMI LockPro2x 2X-C32-1G (K1) / 2X-C32-2G (K2) SFP Modules1x User Instructions
