VOSCOM’s 3G HD-SDI & HD-SDI over Fiber Exntenders provides for the digital transmission of fully uncompressed SDI (270Mbps), HD-SDI (1.485Gbps) or 3G HD-SDI (2.97Gbps) 1080p HD video over a single optical fiber, at broadcast quality.
VOSCOM’s 3G HD-SDI & HD-SDI over Fiber system is an excellent choice for transporting SMPTE 259M, SMPTE 292M or SMPTE 424M compliant video signals over long or short distances with one fiber. In addition, the system support stereo audio, RS485 & RS232 serial data, Loopback output, Contact Closure and IP Ethernet transmission. New signals may be added or fully redundant optical transport solutions may be developed.
applications include specialized Remote OB Van/Truck Video Feeds, Uncompressed Long-Haul Signal Transport, General Broadcast (News/Sports/Events), Broadcast Studio Camera Feeds, where long distance transmission of HD video signals are necessary, fiber optic transmission ensures high quality signals with no interference.
Plug and Play design ensures adjustment-free installation and operation, and optical adjustments are never required. LED indicators are provided to instantly monitor the system operating status.
As with all VOSCOM products, these video devices carry a lifetime warranty. Please give our sales department an E-mail: sales@voscom.com or Feedback with any questions. We would be delighted to contact with you.

SDI, HD-SDI & 3G-SDI:
Serial Digital Interface (SDI) is a serial link standardized by ITU-R BT.656 and the Society of Motion Picture and Television Engineers (SMPTE). SDI transmits uncompressed digital video over 75-ohm coaxial cable within studios, and is seen on most professional video infrastructure equipment. The first revision of the standard, SMPTE 259M, was defined to carry digital representation of analog video such as NTSC and PAL over a serial interface and is more popularly known as Standard-Definition (SD) SDI. The data rate required to transmit SD SDI is 270 Mbps.
With the advent of High-Definition (HD) SDI video standards such as 1080i and 720p, the interface was scaled to handle higher data rates of 1.485 Gbps. The 1.485-Gbps serial interface is commonly called the HD SDI interface and is defined by SMPTE 292M, using the same 75-ohm coaxial cable. Studios and other video production facilities have invested heavily on the hardware infrastructure for coaxial cable and have a vested interest in extending the life of their infrastructure.
Fortunately, SMPTE recently ratified a new standard called SMPTE 424M that doubles the SDI data rates to 2.97 Gbps using the same 75-ohm coaxial cable. This new SMPTE standard, also called 3-Gbps (3G)-SDI, enables higher resolution of picture quality required for 1080p and digital cinema.
