Model:LNK-MHD-1V
Overview
The LNK-MHD-1V Series Mini HD-SDI Fiber Converter supports the transmission of 1-channel HD-SDI video
(with embedded audio) and Tally or reverse RS485 signals over fiber optic cable, while allowing local monitoring
via an HD-SDI loop output.
E-link’s HD-SDI Video over Fiber Converters system consists of a transmitter and a receiver designed to
transmit HD-SDI signals efficiently over long distances using fiber optic technology.
Features
► Each channel includes 8-channel audio embedded;
► Automatic cable equalization, used for all rate below 1.5 Gb/s (Belden 1694A);
► Automatic reclocking 270Mbit/s - 1.48Gbit/s
► Directly compatible with HD-SDI camera systems
► Long transmission capability up to 80 km
► Hot swap and hot plug;
► Handle all Pathological patterns, fully digital non-compression broadcast level transmission;
► LED Status Indication to monitor the working conditions;
► Super optic dynamic range and free of adjustment;
► 1470~1610nm CWDM wavelengths optional;
