SMB 3G/HD/SD-SDI Optical Micro-Extender
SDI Micro Extender Fiber Optic Overview
This 3G-SDI/HD-SDI/SD-SDI miniature fiber optic extender transmits a 3G-SDI, HD-SDI, SD-SDI,
or DVB-ASI high-definition digital video signal over single-mode or multimode fiber. Compliant with
SMPTE 424M, SMPTE 259M, SMPTE 297M, SMPTE 310M, and SMPTE 305M (SDTI) standards,
it utilizes advanced digital fiber optic transmission technology and requires no adjustments, making it easy
to install and operate. Powered by a low-power 5V power supply and compact in size, it's ideal for broadcast,
video production, and multimedia transmission applications.
SDI Micro Extender Fiber Optic Features
► 3G-SDI/HD-SDI/SD-SDI signal auto recognition, no manual selection necessary
► Transmission distance up to 120km
