INTRODUCTION
The EX-36KRS 12G/6G/3G/HD/SD-SDI Fiber Extender with Bi-Directional RS232/422/485 is an
ideal and cost-effective 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
12G/6G/3G/HD/SDI electrical input, perfectly converts SMPTE 292M, SMPTE 259M, SMPTE 424M,
SMPTE 2082 or DVB-ASI electrical SDI signal to single-mode optic SDI signals. The receiver module
receives the corresponding optical signals through input SFP connector, and then perfectly converts it
back to electrical signals. EX-36KRS passes the pathological pattern (SMPTE RP-198) test without
introducing any flickers, and this feature further guarantees the transmission quality over optical
fibers.
Both transmitter and receiver provide equalizing and re-clocking at input unit in order to
re-construct the signals and keep the integrity of signal quality. The EX-36KRS is perfect for today’s
broadcast or surveillance applications, including super long ranged A/V & serial control transmission,
video production, video editing, studio to studio and studio to CATV head end. EX-36KRS is equipped
with bi-directional RS-232/422/485 serial port control. This bonus feature allows users to boost
RS-232/422/485 control distance up to 10km (32800ft) through optical fiber cables. In addition, since
the optical transmission is inherently secure and immune to the outside electronical interferences,
the potential applications are particularly favored in government, military, and medical environments.
