Ikhebula Ukuxhumana: izinhlobo nokusetshenziswa

Ingqalasizinda zokuxhumana ngocingo amanethiwekhi kuhilela ukusetshenziswa sebuningini hardware. Lowo oyinhloko liyisici wire, okuyinto eyenza ukudluliswa kolwazi. Imvamisa omsakazo kungaba isinyathelo, futhi njengoba isiteshi ikhebula. Indlela yesibili esiwusizo kakhulu, ngakho-ke isetshenziswa kaningi. Nokho, kuleli qembu kukhona zenyathi eziningi ukulungiswa ezihlukahlukene iziqondiso abezindaba. It is sekuthandwa kakhulu fibre optic ikhebula uxhumano, kodwa futhi wiring bendzabuko ulahlekelwe isikhundla emakethe yayo. I evamile pair nesisontekile, ikakhulukazi zenani ngoba ukuyikhokhela nokuzinza isihlobo ukudluliswa kwedatha.

Ukusetshenziswa amakhebuli

Izintambo zalolu hlobo asetshenziselwa ukudlulisa ulwazi ahlukene. Ikakhulukazi, imigqa uhlele ukusakaza isignali ithelevishini, ukuxhumana ngocingo futhi digital idatha yezokuxhumana. Ngakho, kungaba khona ngezinhloso ezehlukile ngokuya esikalini bese ubeka gasket. Kukhona elide, inter-kwesifunda futhi imigqa zonal. Kwaba khona futhi nesikhamo ahlukene ngezigaba amanethiwekhi e emakhaya nasemadolobheni ukuthuthukiswa zokuxhumana. Lines abekwa hhayi ngaphandle kuphela, ukwakha emoyeni futhi imigudu ezweni, kodwa futhi izakhiwo ukuxhumana ngqo ihadiwe. Ijwayelekile eziningi zocingo ikhebula, isibonelo, kungaba ngaphansi kwamanzi, nogange. Ukuba Ngowenkolo isigaba esithile kunquma ukuthi ukufakwa.

ama-apharathasi Ikhebula wezokuxhumana

Isakhiwo ikhebula lingasetshenziswa wezinto ambalwa. Isisekelo, uqobo "umongo" conductive, futhi lapho isignali idluliselwa. Idivayisi elula has a izintambo olinganiselayo, asebenzisa emibili izintambo efanayo yakha umbhangqwana kakhulu efanayo elisontiwe. Phawula futhi ekuvikeleni izinto. Basuke emelelwa ezinengilazi ahlukahlukene, kodwa ezivame kakhulu futhi yangaphandle ukwahlukanisa emgodleni esivikela amakhebuli. imigqa Ukuxhumana anganikeza ngamazinga ahlukene yokuvikela wiring kuye ngokuthi izimo yokusebenza ye indlela laying. Ehleliwe cabling uhlelo ayikwazi kubhekwe ngaphandle kukhulunywa izesekeli kanye namadivayisi zokusiza, okuvumela ukuba enze ukufakwa kahle. Kuleli qembu lama-elementi kuhlanganisa ezikhumulweni ahlukahlukene, nezixhumi, patch panel kanye ezivalekile.

izinhlobo amagobolondo

Njengoba sekuphawuliwe kakade, igobolondo has a umsebenzi zokuzivikela, ngakho izimo ukusetshenziswa phezu ngentengo yasemgwaqeni lokhu kwanda impahla. Lokhu enamathela ivikela hhayi kuphela umqhubi, kodwa izingqimba ukwahlukanisa ngoba umswakamo ukuxhumana enamathela ungase uphazamise ngisho kulimaze esigabeni umugqa. Ngakho, igobolondo siqukethe yokugcizelela futhi uphawu izingqimba. I metal, epulasitiki, iraba, futhi iphepha Lingase lisetshenziselwe njengoba material for them. A indima ekhethekile idivayisi kudlala metal, ngoba ongenza umsebenzi ukuzivikela. izinhlobo ezivamile zokuxhumana izintambo, kuhlanganise coaxial futhi lesinesitfombe-sibuko, ungase unikezwe esikrinini esekelwe uthayela, Mesh noma ucwecwe. Kukhona iqembu ulwelwesi wenza PVC. Lena impahla sasivumela esiwusizo futhi functional, lokukhulunywa ngako kulendzaba kungaba yingxenye nokuvikelwa ngokomzimba, kanye Semiconductor, futhi ungqimba ukwahlukanisa.

ikhebula coaxial

kwakheka isisekelo ikhebula is amasilinda ezimbili diameters ezahlukene, ogama-eksisi edlelana. Ngesikhathi esifanayo, enye yalezi izakhi ibekwa nezinye, yakha ukucushwa kwe umqhubi okuqhubekayo kwangaphakathi. Amadivayisi anjalo asetshenziselwa ukusakaza phezu ububanzi imvamisa bohlu. Iningi ukuzinza okusezingeni eliphezulu ngokuya izici kagesi zokuxhumana esebenzayo ikhebula kuyahluka kuze 4 GHz. Ngenxa yalesi sizathu, izintambo coaxial elisetshenziswa umsakazo kanye microwave izinhlelo, ikhompyutha amanethiwekhi wendawo endaweni, kanye nengqalasizinda ukuhlinzeka ikhebula ithelevishini. Ngaphezu kwalokho, inkonzo ngocingo abahlinzeki ukusebenzisa lolu amakhebula kubekwa backbone amanethiwekhi, okuyinto ngokwalo liwubufakazi nokwethenjelwa eliphezulu umkhiqizo. Njengoba imishini igobolondo ovikelayo ke lo mhlahlandlela sebenzisa uhla egcwele izixazululo eyayiqhutshwa iphepha emazombezombe up armored steel tape. Kwezinye izimo, le ntambo wabeka futhi ayiwavikeli - egijima enqunu.

ikhebula ziyalingana

Kulokhu imicu kuthiwa aluka e amaqembu angawodwa, isb pair elisontiwe. Leli lungiselelo kudala kokubili uchungechunge imicu zilingane nemibandela, kunciphisa umthelela izintambo komunye nomunye. ukunyakaza obungaphansi uvinjelwe buphele ezindaweni Curves kanye round ukuma agcinwe. Ngaphandle classical pair nesisontekile, kukhona chetverochnaya ukucushwa, kanye isakhiwo kabili futhi hybrid. Ukuze kube lula elungile ziyalingana abakhiqizi ikhebula inhlangano kwilebula iqembu nombala ofanayo ngalinye. I shades eziyisisekelo avame ukusetshenziswa ngambili, kukhona obomvu noluhlaza okwesibhakabhaka. Kungakhathaliseki izinga igobolondo, ikhebuli zokuxhumana inikezwe kanye kwangaphakathi izintambo emazombezombe. Ukuze wenze lokhu, ukusebenzisa anemibala zokwenziwa noma ukotini ntambo.

Fibre optic amakhebuli

amakhebuli Optical yakha ingilazi bilayer kwakhiwa ingilazi multi-ingxenye noma asebenza ngebhethri. By the way, ububanzi umucu ezinjalo kuba 100-150 microns. Njengoba ukwahlukanisa esetshenziswa kanye nokuqinisa indlela enhle imicu plastic. I enamathela ovikelayo kuyakhethwa kuncike izimo zokusebenza, kodwa bohlu kuyafana esimweni nge ezivamile wire uxhumano. Kubalulekile wazi ukwehlukana izintambo ezinjalo ku multimode futhi singlemode. Umehluko omkhulu phakathi kwalezi zinto zombili inquma usayizi nengaphakathi okungase emelelwa eyodwa noma ngaphezulu Imicu yotshani mncane. Ngokwesibonelo, elilodwa-mode ikhebula has a ukushuba mayelana 8-10 microns, ngaleyo ndlela asuse ukuhlakazwa eyisibonelo. Ngakwelinye ihlangothi, umnyombo imicu multimode isesikhathini microns 60. Naphezu idatha okusezingeni eliphezulu ukudluliswa nesivinini, iziteshi ezifana iphelelwa olulodwa-mode ukuhlakazwa ngenxa ukuhlanekezela.

Izintambo ngenhloso letsite

Lesi sigaba sihlanganisa izintambo nge ikhava armored, esivikela isisekelo emathonyeni angaphandle. I enamathela yangaphandle kungase emelelwa okuqinile steel wire izakhi. Ngokuvamile, izinga lokuba eliphezulu of ukuvikelwa yangaphandle iyadingeka ukuze inethiwekhi, kubekwa okumele kwenziwe ngaphansi kwamanzi. Kule umbono kufanele ihlukaniswe wire phezu kolwandle emfuleni. Esimweni sokuqala umklamo ibalwa kusukela ikhono ukuvikela shock wave, ezihambayo phansi enamadwala, ukumelana nomthelela nokunye ice. G., ukuvikelwa okunjalo luyasetshenziswa ezimbili ungqimba wire zempi izintambo zabo ubukhulu kuyinto 4-6 mm.

River ikhebula uxhumano ikhipha ezahlukene kusukela ukuxhumana komhlaba ohlangothini yalolu hlobo. Nokho, kulesi simo-ke kunikeza ukujiya okwandisiwe steel noma emgodleni phambili. Hhayi izimfuno eliphezulu nokunye wiring ugu. amanethiwekhi ezinjalo zinikezwa nomunye ungqimba zempi, eyenziwe round steel wire 6 mm ububanzi.

Ukubeka ikhebula uxhumano

Ngokuvamile izixhumanisi abekwa komhlaba endaweni indle ekhethekile. Onjiniyela bavame ukuba ehholweni ngendlela akha inombolo okungenani amajika. Ezimweni ezimbi kakhulu, imithombo zidalwe - iphuzu lapho kukhona isixha ikhebula ngabanye ubude ukuqinisekisa ematfuba. Kukhona ezinye izici kubekwa imigqa fiber-optic. Ubunzima main ukusebenza wiring ezinjalo kuyadingeka ukuze sifinyelele ukungezwani elilungile. Ngemva kokuphela umugqa ezweni bangena isakhiwo, lapho kwenziwa iziqobosho kanye uxhumano. Ngokwesibonelo, ikhebula ngocingo, ngenxa yobukhulu balo, ingafakwa nge nenkanuko edlulele omfisha ekhethekile noma izipikili. Kodwa, ngokuya okuqonda zangaphandle, isixazululo esingcono kakhulu yayiyobizwa ukudweba umugqa ngomzila ngaphansi baseboard noma niche underceiling.

isiphetho

Namuhla, noma yimuphi umnikazi we womzalwane ungakwazi ukuhlela yesimanje ezambiwa ikhebula uxhumano ekhaya lakho ngaphandle kwezinkinga lobuchwepheshe. Njengoba umkhuba ubonisa, ukubala lesifanele yokuqala umcimbi kakhulu kwandisa amathuba okuthi kumiswa inethiwekhi okuhlala. Kulokhu, intambo intengo uxhumano ukusetshenziswa ekhaya ububanzi ngokwesilinganiso phakathi ruble 100 no-200. 1 imitha, okuyinto ikuvumela ukuba hhayi skimp on materials izinga. I izixazululo kuyabiza namuhla iphrezenthe fibre optical njengoba isiginali umhumushi kahle kakhulu. Kubiza ezingaphezu kuka izixazululo bendabuko, kodwa ukufakwa eyodwa lokhu kukhetha buyafaneleka. Uma kuhlelwe ukuze lelisu emikhulu iphrojekthi ke ungase ufune ziyakuvimbela yini ukusetshenziswa izintambo coaxial noma izinhlangothi zazo ziyalingana.
