Intercom / Return Video 3G SDI To Fiber Optic Converter , Audio Sdi Video Converter
Audio , Ethernet , Tally , Intercom & Return Video 3G SDI to Fiber Optic Converter
Model: LNK-MSDI Series
Overview
The LNK-MSDI Series allows you to transmit 3G, HD or SD-SDI as per SMPTE 424M-2006, 292 and 259 with the ability to transmit 10/100 Base-T Ethernet RS422, Audio, Ethernet, Tally, Intercom & Return Video over single mode or multimode fiber. All data channels are available simultaneously. The system transports a 3G/HD-SDI signal from the camera to the Base Station and a return video (3G/HD-SDI), Remote control data, genlock, intercom, tally, audio and 10/100M Ethernet are also provided. The system puts all of the signals needed for multi-camera 3G/HD-SDI production onto a SM/MM tactical or SMPTE hybrid fiber cable, insuring robust, trouble-free connectivity on any studio or remote production.
