  • Each Channel supports SMPTE standard of SDTV (143-540Mbps), HDTV (1.485Gbps) and HDTV (3Gbps, 1080p60). Each channel SDI individually re-clocked input and individually re-clocked SDI output
  • Embedded audio / data support for each channel.
  • LED indicators for channel activity and power


BY-SDI-390 is a self contained fiber transmission kit for the transporting 4 discreet SDI signals (or 4K UHD / 12G uncompressed) over one (1) single fiber link. The kit includes the fiber transmitter, fiber receiver and power supplies. This is an ideal solution for the transmission of multiple uncompressed SDI streams, or 4K/UHD up to 10km with zero singla losses. 

Each channel is fully independent. For 4K/UHD application, the signal is splitted over 4 separate 3G SDI links (12G) and supports full 4K/UHD resolution at 60fps. The system is able to combinate SDI signals with a mix of formats and bit-rates if required. Each channel will automatically detect and reclock SDI bit rates of 270Mbit, 1.48Gbit and 2.97Gbit.
