1Ch Bidirectional 3G-SDI with Loop-out + 1Ch Tally + 2Ch Bidirectional RS485 or RS422 + 2Ch Stereo Audio + 1Ch Microphone over Fiber Converter
SDI Fiber Extender Overview
The LNK-3G-1BV1T2BD2A1M series is a high-performance 3G/HD-SDI video optical transceiver.
It supports one-channel bidirectional 3G/HD-SDI video transmission (with embedded audio) ,
video loop-out , one tally signal , two-channel bidirectional RS485/RS422 data , two-channel
external stereo audio , and one microphone signal , transmitting high-definition video
and audio signals over optical fiber.
This series includes one transmitter and one receiver, supporting 1080P Full HD 3G/HD-SDI signal
transmission , and offers high stability and clear images . LED status indicators are included on
the device for real-time monitoring of operating status.
Applicable to: intelligent traffic monitoring, security systems, industrial monitoring
(electricity, chemical industry, steel, oil, railway, etc.), military monitoring (warehouses, borders, etc.),
campus networks, stadium live broadcasts, TV program transmission and other high-demand video
and audio transmission scenarios.
