Model:LNK-3GSDI-4V1DT
► 4 channel 3G/HD-SDI video transmission over optic fiber
► Automatic reclocking 270Mbit/s - 1.48Gbit/s-3Gbit/s
► Directly compatible with 3G/HD-SDI camera systems and support 4Ch Loop output
► Long transmission up to 20 km (12.5miles) (Other distance Optional)
► Support 1Ch backward RS485 and 4Ch Tally
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.
