N3790 Series Expandable Transmission System (Video, Audio, Data, Contact Closure & Intercom)

   Infinova’s N3790 series is a digitally encoded, highly expandable and flexible fiber optic transmission system. Data format supports RS-232, RS-422, 2-wire/4-wire RS-485, Manchester/Biphase and contact closures. Using state-of-the-art CWDM technology, the series can transmit up to 64 channels NTSC, PAL, or SECAM video, 32 channels audio, 32 channels data, 32 channels contact closure signal, or 8 channels intercom. As many as 8 wavelengths can be employed in a specific N3790 product. A broad range of audio, data, contact closure options are available, as simplex and duplex are customized and configurable.
