SDI Optical Transceivers Formerica SDI Optical Transceivers support video pathological patterns for 24G-SDI (8K30), 12G-SDI (4K60), 6G-SDI (UHD-SDI), 3G-SDI, and HD-SDI. The transceivers are compliant with SFP+ MSA, SMPTE ST-2082, and RoHS. These hot-pluggable devices feature an all-metal housing for superior EMI shielding performance. The SDI Optical Transceivers have built-in digital diagnostic functions and an operating commercial temperature range of 0°C to +70°C.
