StarTech ST121HD20FXA2 4K HDMI Over Fiber Extender KIT
Overview
The StarTech ST121HD20FXA2 is a fiber optic extender kit designed to transmit uncompressed 4K HDMI video signals up to 3300 feet (1000 meters) over single-mode or multimode fiber optic cable. This kit is essential for extending high-resolution video feeds in large facilities like warehouses, manufacturing plants, or commercial buildings where standard HDMI cable runs are insufficient. It supports advanced features like HDR10 and HDCP 2.2, ensuring compatibility with modern displays and source devices, while also passing 7.1 channel audio and RS232 serial data.
Compatibility
This extender kit is compatible with any HDMI 2.0 source device and display that supports 4K resolution at 60Hz, HDR10, and HDCP 2.2. It utilizes standard LC fiber connectors, making it compatible with a wide range of single-mode and multimode fiber optic cables. The included power adapters (100-240V AC input, 5V DC output) ensure broad power compatibility. It also supports RS232 serial communication for control system integration.
