The DVI optical transceiver is composed of a DVI transmitter (DVI-T) and a DVI receiver (DVI-R), which transmit DVI, VGA, Audip, and RS232 signals through a single-core single-mode fiber.
What is a DVI optical transceiver?
DVI optical transceiver is a terminal device for DVI optical signal transmission, which consists of a receiving end and a sending end. A device that can convert a DVI signal into an optical signal through various encodings and transmit it through an optical fiber medium. Since digital technology has obvious advantages in many aspects compared with traditional analog technology, just as digital technology has replaced analog technology in many fields, the digitization of optical transceivers has become the mainstream trend of optical transceivers. At present, there are mainly two technical modes of digital image optical transceiver: one is MPEG II image compression digital optical transceiver, and the other is non-compressed digital image optical transceiver. DVI optical transceivers are mainly used in large LED screens, multimedia information release systems, and are widely used in airports, toll station monitoring centers, shopping malls, government, medical care, radio and television and other occasions.
Application of DVI Optical Transceiver
In multimedia application systems, it is often necessary to transmit DVI digital video signals, audio and video signals, and serial port data signals over long distances. However, when using ordinary cables for long-distance transmission, the output signal will always be poor, which is easy to be interfered, and the displayed image will appear blurred, trailing, and color separation. At the same time, the transmission distance is short, and multiple cables are required to transmit these signals at the same time, which cannot meet the requirements of long-distance transmission in occasions such as multimedia information release. At the same time, optical transceiver transmission has the advantages of small attenuation, wide frequency band, strong anti-interference performance, high security performance, small size and light weight, so it has incomparable advantages in long-distance transmission and special environments. In addition, DVI optical transceiver can transmit serial signals at the same time for communication with LCD, and can also be used as long-distance transmission of touch screen. The application of DVI optical transceiver equipment in multimedia systems can save construction costs and the complexity of wiring, and can ensure the goal of high quality. It is especially suitable for various long-distance applications such as transmission of high-definition video signals in train platforms and military exercises.
The advantages of DVI optical transceiver:
1. Multiple specification options: stand-alone, 1U rack-mount and 4U rack-mount installations are available.
2. Photoelectric self-adaptation: advanced self-adaptive technology, no need for electrical and optical adjustment during use.
3. LED light status display: LED status indicator monitors key parameters.
4. Digital uncompressed: all digital, uncompressed, high-definition transmission.
5. Strong adaptability: suitable for industrial harsh environments such as extremely high temperature and extremely low temperature.
6. Easy installation: no software settings are required, plug and play function is supported, and hot swap is supported.
