HD/SD-SDI over Singlemode LC-type Fiber Optic Extender Immune to Pathological - SF50

Features

Overview

The SF50 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 HD/SDI electrical input, perfectly converts SMPTE 292M, SMPTE 259M or DVB-ASI electrical SDI signal to single-mode optic SDI signals. The receiver module receives optical signal from input LC connector, and then perfectly converts it to electrical SDI signal. SF50 is immune to pathological pattern (SMPTE RP-198) without introducing any flickers, and this feature further guarantees the transmission quality over optical fibers.

Both transmitter and receiver provide equalizing and reclocking at input unit in order to re-construct the signal for consistent quality. The SF50 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.
