Optical hybrid tambo (AOC) uye yese-optical kutapurirana

Optical Transmission

Kubva 2000, nekuvandudzwa kwehunyanzvi hwekutaurirana, optical fiber communication yakaonekwa optical module transmission tekinoroji, uye mushure me2002, digital transmission HDMI audio uye vhidhiyo zviratidzo zvigadzirwa zvakaonekwawo mumunda wemagetsi evatengi.Muna Kubvumbi 2002, Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, Toshiba makambani manomwe akabatana akagadzira HDMI yakakwirira-tsanangudzo multimedia interface sangano, HDMI kutapurirana kwakakamurwa kuita-yepamusoro-speed chiratidzo chekufambisa uye yakaderera-speed chiratidzo chekufambisa zvikamu zviviri. : 1-12 tsoka dze12 4 pairs dzetambo dzinotumira zviratidzo zvepamusoro-soro, vachishandisa TMDS yakasiyana-siyana yekusaina tekinoroji (TMDS (Nguva Yakaderedzwa) yakagadzirwa neSilicon Image Differential Signal) inoderedza kutapurirana kusiyanisa chiratidzo chekufambisa tekinoroji, TMDS inzira yekusiyanisa chiratidzo, uchishandisa differential transmission mode, iyo ndiyo nheyo inokosha yeHDMI teknolojia, mu optical fiber transmission HDMI: idzi 4 pairs dze12 TMDS cables dzinoparidzirwa ne 4 VCSEL + 4 multimode optical fibers, iyo inogona kugadzirisa nyore nyore dambudziko rekufambisa kwepamusoro.

MuHDMI yakaderera-speed transmission channel, iyo 13-19 pini muHDMI ine 7 tambo dzemagetsi: 5V magetsi, HPD inopisa-swap inogadzirisa CEC, internet, SDA, SCA, DDC chiteshi.Iyo inonyanya kukosha yekuratidzira sarudzo inoverenga iyo DDC chiteshi: ndiwo murairo weI2C interface pane HDMI sosi yekuverenga E-EDID pamagumo ekugamuchira.I2C, pfupi yeIntegrated Circuit Bus, ibhazi rekutaurirana rinoshandisa akawanda-master-slave architecture.Iye akatanga I2C zvakare mumwe wevakatanga sangano reHDMI: Philips Semiconductors.

Matambo eHDMI anowanzo shandiswa kubatanidza midziyo yeaudiovisual kuTV uye monitors, saka mazhinji acho ari mapfupi-kufambiswa kutapurirana, kazhinji chete 3 metres kureba;Vashandisi vanofanira kuitei kana vachida kupfuura mamita matatu?Kana iwe ukaramba uchishandisa tambo yemhangura, dhayamita yemhangura yemhangura ichava yakakura, ichava yakaoma kukotama, uye mari yacho ichave yakakwirira.Nokudaro, nzira yakanakisisa ndeyokushandisa optical fibers.HDMI AOC optical hybrid tambo chigadzirwa chaicho chigadzirwa chehunyanzvi hwekukanganisa, chinangwa chepakutanga mukusimudzira chinofanira kunge chiri chekuti tambo dzese dzeHDMI 19 dziri optical fiber transmission, inova ndiyo chaiyo optical fiber transmission HDMI, asi nekuti tambo 7 dzeiyo yakaderera-. speed channel shandisa VCSEL + multimode fiber yakaderera-speed signal encoding uye decoding yakanyanya kuoma, kungoita mugadziri chete chiratidzo chepamusoro-soro mu 4 pairs ye TMDS channels kuVCSEL + multimode fiber transmission, iyo yakasara 7 waya dzemagetsi dzichiri dzakabatanidzwa zvakananga nemhangura. wireZvakaonekwa kuti mushure mokunge chiratidzo chepamusoro-chikurumidzira chichiendeswa nefiber optical, nekuda kwekuwedzera kwe TMDS chiratidzo chekufambisa kure, iyo optical fiber HDMI AOC inogona kuendeswa ku 100 mamita kana kunyange kureba.

Optical fiber HDMI AOC hybrid cable nekuti iyo yakaderera-yekumhanya chiratidzo ichiri kushandisa mhangura waya kutapurirana, dambudziko rekumhanya-mhanya chiratidzo rinogadziriswa, uye dambudziko rekuderera-kumhanya chiratidzo chemhangura chekufambisa hachisati chagadziriswa, saka chinowanzoenderana nekuenderana kwakasiyana. matambudziko mukutapurirana kure-kure.Uye izvi zvese zvinogona kugadziriswa zvachose kana HDMI inoshandisa ese-optical tekinoroji mhinduro.Yese-optical HDMI inoshandisa 6 optical fibers, 4 kuendesa yakakwira-speed TMDS chiteshi masaini, 2 kuendesa HDMI yakaderera-speed masaini, uye yekunze 5V simba rekupa rinodiwa paRX kuratidza kuguma semhepo yekukurudzira yeHPD inopisa plugging.Mushure mekutora iyo yose-optical solution, HDMI, high-speed TMDS chiteshi uye yakaderera-speed DDC chiteshi inoshandurwa kuita optical fiber transmission, uye kureba kwekufambisa kunovandudzwa zvakanyanya.
