Digital connectivity products manufacturer DVIGear has introduced the DVI-7380, a DisplayPort optical extender designed to meet and exceed even the most demanding high-performance system requirements.

Per the manufacturer, the DVI-7380 supports a wide array of signal types, provides long-distance extension over a single fiber cable, and supports ultra-high resolutions up to 8K (UHD) at 30Hz (4:4:4).

Multiple signals extend over a single fiber cable

Using only a single fiber-optic cable, the DVI-7380 supports:

  • DisplayPort 1.4 HBR3 signals with data rates up to 8.1Gbps/channel (32.4Gbps aggregate).
  • Video resolutions up to 8K /30p.
  • Embedded audio.
  • Bi-directional IR
  • RS-232
  • (2) 10/100 BaseT Ethernet ports.

The DVI-7280 can extend these signals over cable distances of more than 5.0 miles (> 8,000 meters) using singlemode fiber, and up to 1000 ft. (~ 300 meters) using multimode fiber.

Fiber technology details

The extender set consists of an optical transmitter unit and an optical receiver unit.

The transmitter converts the AV signals into light pulses for transmission over a single strand of multimode or singlemode fiber-optic cable.

The receiver converts the light pulses back to AV signals for the display, as well as other downstream devices.

According to DVIGear, "By using advanced fiber-optic technology, without any compression, this product provides superior picture quality over greater distances than other extension methods, such as copper cables or CAT-X extenders."

A company press release continues: "Moreover, optical fiber transmission is immune to environmental signal noise, thus providing a low RFI / EMI profile for sensitive applications where security is an important concern. Together, these features make the DVI-7380 the ideal, cost-effective solution for system designers and integrators who need to extend high resolution DisplayPort signals over extreme distances with flawless image quality. "

The DVI-7380 extender has a suggested retail price of $1,140 per set and is available for immediate delivery.
