12G-SDI Fiber Optic Extender, 1x LC

Model No: DVI-7348

Rugged, compact extender supports SD-SDI, HD-SDI, 3G-SDI, 6G-SDI and 12G-SDI over one single-mode fiber up to 10 km (6.2 miles). Embedded audio, RS-485 and tally light control are also supported.

Key Features

  • Supports multiple SDI resolutions: SMPTE-259M (SD-SDI), SMPTE-344M (ED-SDI), SMPTE-292M (HD-SDI), SMPTE-424M (3G-SDI), SMPTE-ST-2081 (6G-SDI) and SMPTE-ST-2082 (12G-SDI)
  • Supports data rates up to 11.88 Gbps
  • Utilizes a single optical cable
  • Supports Single-Mode optical fiber distances up to 6.2 miles (~ 10 km)
  • Extended length 25 miles (~ 40 km) option available
  • Compact, rugged metal enclosure with locking BNC connectors
  • Supports RS-485 and Tally Light Control for remote control of acquisition cameras
  • Wide operational temperature range: -40° to +185°F (-40° to +85°C)
  • Low RFI / EMI profile for sensitive applications
  • Optical fiber transmission is immune to environmental signal noise

High Performance — The DVI-7348 is a compact, high performance fiber optic extender that supports SDI, HD-SDI, 3G-SDI and 12G-SDI signal extension over a single strand of Single-Mode optical fiber at distances up to 6.2 miles (~10 km). This extender set consists of an optical transmitter unit that converts the SDI signals into light pulses for transmission over an optical fiber cable. An optical receiver unit converts the light pulses back to an SDI signal for downstream processing or display on a monitor.

Superior Design — The transmitter unit includes an SDI input with a buffered loop-through SDI output, plus connections for RS-485 and Tally Light control. The receiver unit includes two buffered SDI outputs, as well as connections for RS-485 and Tally Light control, which allows equipment in the control room to access and control acquisition cameras over the optical link. Both units are housed in rugged, die-cast metal cases equipped with 75-ohm BNC connectors. A single LC fiber optic connection is used to link Tx and Rx units.

These features make the DVI-7348 the perfect solution for extension of SDI, HD-SDI, 3G-SDI, and 12G-SDI signals over very long distances in even the most demanding broadcast, studio, and live production environments.
