The Extron FOX3 SR 311 fiber optic scaling receiver provides long-haul transmission of HDCP-compliant HDMI video, USB HID, audio, control, and 3D sync over fiber optic cable. Engineered for exceptional high-resolution image performance, it uses Extron all-digital technology to deliver perfect pixel-for-pixel, uncompressed transmission of images up to 4K/60 @ 4:4:4 over two fibers or mathematically lossless 4K/60 @ 4:4:4 over one fiber. The USB HID port applies device class filtering to restrict the device types to HID. Designed specifically for AV and KVM systems, the FOX3 SR 301 also includes many integrator-friendly features such as Key Minder, audio de-embedding, Ethernet monitoring and control, and real-time system monitoring.
