Feature:1. Function: Extends HD 4K HD Multimedia Interface signals up to 12.4 miles (20 km) over a single mode fiber optic cable with KVM capability (USB port) for remote control via mouse and keyboard.2. Universal to Use: 20km HD Multimedia Interface fiber optic extender is common to both fiber types, and the same media converter can support both single mode fiber and multimode fiber. SC optical connector. Wavelength 1310 1550 nm.3. High Resolution, Aluminum Alloy: Supports video resolutions up to 4K 60Hz and is backward compatible. Durable aluminum alloy material. Bilateral heat dissipation. LED lights. Installation is simple, plug and play, and requires no setup or configuration.4. Widely Compatible: HD Multimedia Interface fiber optic extender is widely used to extend high definition sources such as blue lighting players, game consoles, PCs, and other HD Multimedia Interface sources to distant monitors, monitors, TVs, and more.5. Superior Performance: With HD Multimedia Interface over fiber optic extenders, you get faster speeds, less signal attenuation, longer data transmission distances, better reliability, and greater flexibility. Because optical fibers are highly resistant to electromagnetic interference, the bit error rate of fiber optic cables is low.Specification:Item Type: HD Multimedia Interface Over Fiber Optic ExtenderMaterial: Aluminum AlloyHD Multimedia Interface Version:4K 60Hz HDCP2.2Resolution: 3840x2160Supported Sound Format: L PCMFiber Wavelength: 1310nm; 1550nmOptical Fiber Transmission Distance: 20kmMaximum Operating Current: 1.5A 12V(TXC); 1.2A 12V DC（RX）.Package List:1 x Receiver1 x Transmitter2 x Infrared Cable1 x USB Cable2 x Power Adapter1 x Instruction Manual
