Abstract
The utility model discloses a four-core optical fiber HDMI optical transceiver including a receiver and a transmitter. The transceiver includes a plurality of optical transmitting modules. The optical transmitting modules connect with an input terminal of a video distribution module through a TMDS signal equalizer. An output terminal of the video distribution module connects with an HDMI output connector. The transmitter includes a TMDS signal amplifying module. An input terminal of the TMDS signal amplifying module connects with an HDMI input connector while an output terminal of the TMDS signal amplifying module connects with the optical transmitting modules. The HDMI output connector of the receiver connects with the HDMI input connector of the transmitter remotely through an optical fiber. In the utility model, the four-core optical fiber HDMI optical transceiver can realize the optical fiber transmission of multi-channel signals through arranging the video distribution module and the optical transmitting modules, thereby providing lossless long-range HDMI signal transmission.
Description
Technical field
The utility model relates to a kind of optical transmission device, relates in particular to a kind of four-core optical fiber HDMI optical transceiver.
Background technology
HDMI is the abbreviation of High Definition Multimedia Interface (high score numeral multimedia interface), can be regarded as reinforcement and the extension of DVI, and both can be compatible.HDMI is in the high-resolution video and the multichannel audio data that guarantee can transmit with digital form under the high-quality situation uncompressed.HDMI can support all ATSC HDTV standards; Not only can satisfy the resolution of at present high image quality 1080p; Can also support state-of-the-art digital audio formats such as DVDAudio; Support the transmission of Eight-channel 96kHz or stereo 192kHz digital audio, and only connect, can be used to exempt the digital audio wiring with a HDMI line.
At present; The HDMI signal adopts the HDMI cable transmission mostly, and along with the extensive use of high definition product, the resolution of terminal presentation facility is increasingly high; Definition to signal is also increasingly high; And the loss of institute's transmission signals is very big in the existing aaaanalog transmission system, can't satisfy the demonstration of high definition and the needs of long Distance Transmission, therefore is necessary to provide a kind of HDMI optical transceiver of harmless long distance.
The utility model content
The utility model technical problem to be solved provides a kind of four-core optical fiber HDMI optical transceiver, and the HDMI signal transmission of harmless long distance can be provided.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of four-core optical fiber HDMI optical transceiver; Comprise receiver and transmitter; Said receiver comprises a plurality of optical transmission modules; Said optical transmission module links to each other through the input of TMDS signal equalizer and video distribution module, and the output of said video distribution module links to each other with the HDMI out connector; Said transmitter comprises TMDS signal amplification module, and the input of said TMDS signal amplification module links to each other with the HDMI input connector, and output links to each other with a plurality of optical transmission modules; The HDMI out connector of said receiver and the HDMI input connector of transmitter link to each other through optical fiber remote.
Above-mentioned four-core optical fiber HDMI optical transceiver, wherein, said optical transmission module number is 4, the HDMI out connector of said receiver and the HDMI input connector of transmitter link to each other through 4 core fibres are long-range.
The utility model contrast prior art has following beneficial effect: the four-core optical fiber HDMI optical transceiver that the utility model provides; Realize the Optical Fiber Transmission of multiple signals through video distribution module and a plurality of optical transmission module are set, thereby can provide the HDMI signal of harmless long distance to transmit.
