Product Description

The ST-806 – 3G/HD/SD-SDI Extender over Fiber Optic is an ideal and economic solution designed for transmission of multi-rate SDI video, with embedded audio and metadata over a single-mode fiber optic cable. The transmitter module receives one 3G/HD/SDI electrical input, perfectly converts SMPTE 292M, SMPTE 259M , SMPTE 424M or DVB-ASI electrical SDI signal to single-mode optic SDI signals. The receiver module receives optical signal from input SFP connector, and then perfectly converts it to electrical SDI signal.
Both transmitter and receiver provide equalizing and reclocking at input unit in order to re-construct the signal for consistent quality. The ST-806 include Tx and Rx and is perfect for today’s broadcast applications, including video production, video editing, studio to studio and studio to CATV head end. In addition, since transmission of content is inherently secure and immune to outside interference, fiber applications are favored in government, military, and medical environments.
