Umugozi utandukanye USB4 insinga

Bus ya Universal Serial Bus (USB) birashoboka ko ari imwe mumikorere itandukanye kwisi.Byabanje gutangizwa na Intel na Microsoft nibiranga nkibikoresho bishyushye no gukina bishoboka.Kuva hashyirwaho USB interineti muri 1994, nyuma yimyaka 26 yiterambere, binyuze muri USB 1.0 / 1.1, USB2.0, USB 3.x, amaherezo yateye imbere kuri USB4 y'ubu;Igipimo cyo kohereza nacyo cyiyongereye kuva kuri 1.5Mbps kugera kuri 40Gbps iheruka.Kugeza ubu, ntabwo telefone zigendanwa zashyizwe ahagaragara gusa zishyigikira interineti ya C-C, ariko kandi na mudasobwa yamakaye, kamera ya digitale, disikuru zikoresha ubwenge, ibikoresho byamashanyarazi bigendanwa nibindi bikoresho byatangiye gukoresha TYPE-C yihariye ya USB, yatangijwe neza. mumashanyarazi.Mu mwanya wa USB-A, Model 3 nshya ya Tesla ifite ibyambu bya usB-C, kandi Apple yahinduye rwose macBooks na AirPods Pro ku byambu bya USB Type-C byera byo kohereza amakuru no kwishyuza.Mubyongeyeho, ukurikije ibisabwa eu, pome izanakoresha USB ubwoko bwa c-interineti mugihe kizaza cya iPhone15, kandi ntagushidikanya ko USB4 izaba interineti nyamukuru yibicuruzwa kumasoko azaza.

Ibisabwa kuri USB4

Impinduka nini muri USB4 nshya ni intangiriro ya protocole ya Thunderbolt Intel yasangiye na usb-niba.Kwiruka hejuru yuburyo bubiri, umurongo wikubye kabiri kugeza kuri 40Gbps, kandi Umuyoboro ushyigikira amakuru menshi no kwerekana protocole.Ingero zirimo PCI Express na DisplayPort.Mubyongeyeho, USB4 ikomeza guhuza neza nogutangiza protocole nshya ishingiye, kuba inyuma igahuzwa na USB3.2 / 3.1 / 3.0 / 2.0, kimwe na Thunderbolt 3. Kubera iyo mpamvu, USB4 yabaye USB igoye cyane kugeza ubu , bisaba abashushanya gusobanukirwa USB4, USB3.2, USB2.0, USB Type-C na USB Imbaraga zitangwa.Mubyongeyeho, abashushanya bagomba gusobanukirwa PCI Express na DisplayPort ibisobanuro, kimwe nubuhanga bwa HIGH-DEFINITION bwo kurinda ibintu (HDCP) bujyanye nuburyo bwa USB4 DisplayPort, hamwe ninsinga hamwe nabahuza tumenyereye bifite ibisabwa byinshi kugirango byuzuze amashanyarazi akora ibisabwa bya USB4 ibicuruzwa byarangiye.

Verisiyo ya coaxial ya USB4 yavuye ahantu

Mugihe cya USB3.1 10G, abayikora benshi bafashe imiterere ya coaxial kugirango bahuze ibisabwa nibikorwa byinshyi.Verisiyo ya Coaxial ntabwo yigeze ikoreshwa muri seriveri ya USB mbere, ibintu byayo ni cyane cyane Ikaye, terefone igendanwa, GPS, igikoresho cyo gupima, tekinoroji ya Bluetooth, n'ibindi. etc. kwihuta kwihuta bikenera insinga bifite imbaraga zikomeye zo kurwanya-interineti nimbaraga zumuriro wamashanyarazi, Kugirango hamenyekane ituze ryogukwirakwiza kwinshi, imiyoboro nyamukuru ya USB4 iracyari verisiyo nyamukuru ya coaxial, umusaruro wa coaxial nibikorwa byo gukora ninzira igoye, kugirango ikemuke umuvuduko mwinshi hamwe nihuta ryihuse bisaba ibikoresho bibyara umusaruro bikwiye kandi bikuze kandi bihamye.Mu musaruro wibicuruzwa, guhitamo ibikoresho, ibipimo byuburyo no kugenzura inzira, ibipimo byamashanyarazi byibizamini bya laboratoire bigira uruhare runini, mugihe cyose iterambere ryiterambere ryimiterere ya coaxial, hiyongereyeho (igiciro cyibikoresho, igiciro cyo gutunganya gihenze) ibindi nibyiza, ariko iterambere ryisoko rihora rizenguruka muburyo bwo kugera ku giciro kinini cyicyiciro, Pair ya twist verisiyo yamye ari icyuho cyubushakashatsi bwiterambere ryiterambere hamwe niterambere.

Irashobora kugaragara uhereye kumiterere yumurongo wa coaxial, uhereye imbere ukageza hanze, muburyo bukurikira: umuyoboro wo hagati, urwego rukingira, urwego ruyobora hanze (meshi yicyuma), uruhu rwinsinga.Umugozi wa Coaxial ni compte igizwe nabayobora babiri.Umugozi wo hagati wumugozi wa coaxial ukoreshwa mugutanga ibimenyetso.Urushundura rukingira icyuma rufite inshingano ebyiri: imwe ni ugutanga icyerekezo kigezweho kubimenyetso nkibisanzwe, naho ubundi ni uguhagarika kwivanga kw urusaku rwa electromagnetiki kuri signal nkurushundura rukingira.Umugozi wo hagati hamwe numuyoboro ukingira hagati ya polipropilene ya polipropilene igice cya kabiri, urwego rwimikorere rugena ibimenyetso byogukwirakwiza umugozi, kandi rukarinda neza insinga yo hagati, bihenze bifite impamvu zihenze.

USB4 yagoretse verisiyo iraza?

Mugihe imiyoboro ya elegitoronike ikora kumurongo mwinshi, ibiranga amashanyarazi yibikoresho bya elegitoronike bigorana kubyiga.Iyo ingano yibigize cyangwa ingano yumuzunguruko wose ugereranije nuburebure bwumurongo wumurongo wikurikiranya urenze umwe, agaciro ka capacitance yumuzunguruko wumuzunguruko, cyangwa ibice ingaruka za parasitike yibintu nibintu nibindi, nubwo twakoreshaga imiterere ya wire, ibipimo fatizo ibipimo byipimisha ntibishobora kuba byujuje ibyifuzo byabakiriya, kandi byoroshye kurenza coaxial verisiyo yimiterere na diameter yayo ni kure, Kuki ntashobora gukoresha USB USB mubice?Muri rusange, hejuru yinshuro zikoreshwa rya kabili, nigihe kigufi cyumurambararo wikimenyetso, kandi ntoya ya skew ikibanza, nibyiza kuringaniza.Nubwo bimeze bityo, uduce duto cyane tuzana umusaruro muke hamwe na sprain ya insinga yibanze.Ikibanza cyumurongo ni gito cyane, umubare wa torsion ni mwinshi, kandi guhangayikishwa na torsion kumurongo byibanze cyane, bikaviramo guhindagurika gukomeye no kwangirika kwurwego, kandi amaherezo bigatera kugoreka umurima wa electroniki, bikagira ingaruka kuri bamwe ibipimo by'amashanyarazi nka SRL agaciro na attenuation.Iyo insulentricité ibaho, intera iri hagati yabatwara ihinduka rimwe na rimwe kubera impinduramatwara no guhinduranya umurongo umwe, bizana ihindagurika ryigihe cya impedance.Igihe cyo guhindagurika ni kirekire.Mugihe cyogukwirakwiza kwinshi, iri hinduka ryihuse rirashobora gutahurwa numuyoboro wa electromagnetic kandi bikagira ingaruka kubitakaza agaciro.Verisiyo ya USB4 ntishobora gukoreshwa mubice.

Ntabwo ari hasi, ariko ntushake gukoresha urupfu rwawe coaxial, abantu rero batangiye kugenzura itandukaniro USB4 ikingira uburyo bwo gukora ibicuruzwa, kugirango wandike ikibi kinini ni umuyoboro uhindagurika byoroshye, kandi itandukaniro hamwe na pake ibangikanye kumurimo wo murugo, irinde kuyobora sprain, nkuko twese tubizi, kurubu UKORESHE itandukaniro rya SAS, SFP + nibindi bikoreshwa mumurongo wihuta, Birahagije kwerekana ko imikorere yayo igomba kuba irenze verisiyo ihagaze, uruhare rukomeye rwumurongo wamakuru ni kohereza amakuru yamakuru, ariko mugihe tuyakoresheje hirya no hino hashobora kugaragara ubwoko bwose bwamakuru yivanga.Reka dutekereze niba ibyo bimenyetso byo kwivanga byinjira mumbere yimbere yumurongo wamakuru hanyuma ukarenga hejuru yikimenyetso cyambere cyatanzwe, birashoboka kubangamira cyangwa guhindura ibimenyetso byambere byatanzwe, bityo bigatera gutakaza ibimenyetso byingirakamaro cyangwa ibibazo?Kandi itandukaniro rya aluminium foil layer ni ukutwoherereza amakuru kugirango dukine uruhare rwo kurinda no gukingira, bikoreshwa mukugabanya kwivanga kwibimenyetso byigenga byo hanze byoherejwe, ibikoresho nyamukuru byumukandara hamwe na aluminiyumu foil gukurura ni ugukoresha kashe ya aluminium no gukingira , uruhande rumwe cyangwa impande zombi kuri firime ya plastike, lu: su composite foil ikoreshwa nkingabo ya kabili.Umugozi winsinga usaba amavuta make hejuru, nta mwobo hamwe nubukanishi buhanitse.Inzira yo gupfunyika ni ugukusanya insinga ebyiri zifunguye hamwe ninsinga zubutaka hamwe hakoreshejwe imashini.Muri icyo gihe, igice cya fayili ya aluminiyumu hamwe na kaseti yo kwifata-polyester kaseti ku mugati wo hanze bikoreshwa mu gukingira insinga no guhuza imiterere yo gupfunyika insinga.Iyi nzira igira ingaruka zikomeye kumitungo y'insinga, harimo impedance, gutinda gutandukanya, kwiyitirira, kubera ko ibyo bigomba kubyara umusaruro ushimishije mubukorikori, gukora ibizamini kumitungo y'amashanyarazi, kugirango harebwe niba insinga zipfunyitse zihuye nibisabwa.Birumvikana, ntabwo imirongo yose yamakuru ifite ibice bibiri byo gukingira.Bamwe bafite ibice byinshi, bimwe bifite urwego rumwe gusa, cyangwa ntanumwe rwose.Gukingira ni ugutandukanya ibyuma hagati yuturere tubiri kugirango tugenzure kwinjiza nimirasire yumuraba wamashanyarazi, magnetiki na electromagnetic kuva mukarere kamwe mukindi.Kugirango bisobanuke neza, intandaro yuyobora izengurutswe numubiri ukingira kugirango wirinde kwanduzwa numurima wa electromagnetic yumurima / ikimenyetso cyo kwivanga, no gukumira interineti yumuriro wa elegitoroniki / ibimenyetso bikwirakwira hanze.USB itandukanyirizo ryibice byinshi byerekana ibimenyetso birashobora kugereranywa na coaxial, itandukanyirizo rya USB4 USB iraza.
