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 masaini akakwira-kumhanya, achishandisa TMDS yekusiyanisa kusaina tekinoroji (TMDS (Nguva Yakaderedzwa) yakagadzirwa neSilicon Image Differential Signal) inoderedza kutapurirana kusiyanisa chiratidzo chekufambisa tekinoroji, TMDS inzira yekusiyanisa chiratidzo, ichishandisa musiyano wekutapurirana modhi, inova ndiyo musimboti weHDMI tekinoroji, mune optical fiber transmission HDMI: idzi 4 pairs dze12 Tambo dzeTMDS dzinofambiswa ne 4 VCSEL + 4 multimode optical fibers, iyo inogona kugadzirisa nyore nyore dambudziko rekukurumidza-kumhanya. kutapurirana.
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, zvichange zvakaoma 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-. kumhanya chiteshi shandisa VCSEL+ multimode fiber yakaderera-kumhanya chiratidzo encoding uye decoding yakanyanya kuoma, kungoti mugadziri anongova chiratidzo chepamusoro-chepamusoro muzvikamu zvina zve. TMDS migero kuVCSEL + multimode fiber transmission, iyo yakasara 7 waya dzemagetsi dzichiri kubatanidzwa zvakananga nemhangura yemhangura. AOC inogona kutapurirwa ku100 metres 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.

Kunyange zvazvo iyo optical copper hybrid line yakasimudza kusarasikirwa kwekutapurirana kwezviratidzo zvekureba kusvika pakakwirira kwazvo, kuchine teknolojia inogadzirisa zvachose kuvapo kwetambo yemhangura semutungamiri wekufambisa, kureva, pure optical fiber HDMI 2.1 mutsara, HDMI 2.1 pure optical active optical cable (AOC) inoenderana zvizere neHDMI 2.1 standard, chiratidzo chekufambisa chiri kushandisa optical fiber, haina mhangura. waya, optical fiber transmission haisi pasi pekukanganiswa kwemagetsi. Chiratidzo cheAOC chekufambisa hachina kumanikidzwa, iyo yakakura bandwidth i48Gbps, inogona kufambisa zvakakwana 8K yekupedzisira-yepamusoro-tsanangudzo mifananidzo, kureba kwekufambisa kureba kunogona kusvika 500m. Kana ichienzaniswa newaya dzemhangura dzechinyakare, iyi fiber optic tambo yakareba, yakapfava, yakareruka, ine mhando yechiratidzo chiri nani uye hunhu hwakakwana hwemagetsi. Mukutanga kwegore, iyo HDMI Association yeHDMI Cable certification bvunzo zvirevo zvekuvandudza kukuru, itsva DMI Passive Adapter certification chirongwa chekuyedza, munguva yakapfuura pasi peiyo Ultra High Speed HDMI Cable bvunzo yakatarwa, mukuwedzera iyo inofanirwa kutsigira HEAC basa, tambo inoshandiswa kufambisa HEAC ichiri kuda kushandisa waya yemhangura kuti isimbiswe, kana iri kushandisa yakazara optical fiber, haigone kupihwa certified, uye Premium High Speed HDMI HEAC basa pasi petambo. tsanangudzo ndeyerutsigiro rwekusarudza, mushure meiyo tsanangudzo yekuvandudza yave sarudzo yekutanga yeyest-fiber AOC Cable panguva ino, pure fiber HDMI yakazozivikanwa zviri pamutemo, zvino zvinonzi HDMI fiber transmission in optical hybrid cable ( AOC) uye zvese-optical kutapurirana izvo zviri nani, kutaura zvazviri, zvinoenderana nemutengo wekuita uye musika wekushandisa kusarudza, imwe neimwe ine zvayakanakira.
