Overview
LNK-3GSDI-4V1DT Series supports 4-channel HD/3G-SDI standard high-definition video signal and
RS485 and Tally signal transmitted via single fiber optical cable. E-link 3G-SDI Video over Fiber
Converters includes one transmitter and one receiver for 1080P 3G-SDI signal. E-link 3G-SDI Fiber
Converters can transmit 4-Ch 3G-SDI Video signal through a single optical fiber, and it support Loop
output, 4Ch Tally and backwards RS485. The video quality is non-compressed broadcast level.
It’s widely used in broadcast field.
