GHB Modular HD-SDI Fiber Link
GHB modular fiber link includes GHBT optical transmitter module and GHBR optical receiver module for 1080i HD-SDI signal or 1080P HD-SDI signal. The HD-SDI channel number over GHB fiber link can be up to 4 over one SM fiber. The GHBT transmitter can be installed next to HD camera while GHBR optical receiver can be installed next to the HD-SDI processing equipment via coaxial digital cable. HD-SDI signal can be 1920x1080 30P or 60P. GHB supports the reverse RS-485 PTZ control signal transmission to each connected HD camera over the same SM fiber. GHBT optical transmitter can work with GHBR receiver or GHCR receiver (multi HD-SDI optical receivers in 19” 1RU chassis)
