Product Overview
QuestTel L-1SDI-SFE-TX/RX is a HD/SD-SDI over singlemode or multimode fiber
transmitter and receiver extender kit. This unit provides optical transmission of one HD/
SD-SDI signal with embedded audio signal and has reversed RS485 data channel for
camera control. The system support signals accord with standards of
SMPTE292M,SMPTE259M,SMPTE297M,SMPTE310, SMPTE305 and support digital
TV signals like DVB-ASI meeting the industrial requirements of audio and video
equipment with high performance and reliability.
The plug-and-play design makes the installation convenient and easy, the LED indicator
design helps the user to know the working status easily, and there is no need for on-site
adjustment. Signal Bit Rate from 270 Mbps to 1.5Gbps. Fiber optical transmission
excludes electromagnetic noise factor, it makes this product a perfect solution for efficient,
reliable and secured HD/SD-SDI signal transport.
