HD SDI Fiber Transmitters extend uncompressed HD-SDI video over fiber. These transmitters support SMPTE 292M, SMPTE 259M or are DVB-ASI compliant. The embedded digital audio stream is also supported by HD SDI Fiber Transmitters. These video data supporting transceivers deliver multi-data rate of 1.485Gbps or 270Mbps on multi-mode fiber support for distance up to 300m and up to 20km on single mode fibers. The operating temperature range of HD SDI Fiber Transmitters is -40oC to +75oC. Cozlink HD SDI Fiber Transmitters are defined by SMPTE 292M using the same 75-ohm coaxial cable, It finds its best utility in running motion pictures. The studios buy expensive infrastructure to use these transmitters and find perfect solution in them for extending the life of this set-up.
