Inethiwekhi yendawo esemgangathweni kwifom yayo yangoku (umyinge) yagqitywa kwiminyaka emininzi eyadlulayo, apho uphuhliso lwayo lwayeka.
Kwelinye icala, olona tshaba lulungileyo, kwelinye icala, ukuzinza nako akulunganga kakhulu. Ngaphezu koko, xa kuhlolwa ngokusondeleyo, inethiwekhi yeofisi yanamhlanje, ekuvumela ukuba wenze phantse yonke imisebenzi yeofisi eqhelekileyo, inokwakhiwa ngexabiso eliphantsi kwaye ngokukhawuleza kunokuba kukholelwa ngokuqhelekileyo, kwaye i-architecture yayo iya kuba lula kwaye iyancipha. Ungandikholelwa? Masizame ukuyiqonda. Kwaye makhe siqale ngento ethathwa njengokubekwa ngokuchanekileyo kwenethiwekhi.
Yintoni i-SCS?
Nayiphi na inkqubo yecabling ecwangcisiweyo (SCS) njengento yokugqibela yeziseko zophuhliso zobunjineli iphunyezwa ngokwezigaba ezininzi:
- uyilo
- ngokwenene, ukufakwa kweziseko zentambo;
- ukufakwa kweendawo zokungena;
- ukufakwa kwamanqaku okutshintsha;
- imisebenzi yokuyalela.
Uyilo
Nasiphi na isithembiso esikhulu, ukuba ufuna ukusenza kakuhle, siqala ngokulungiselela. Kwi-SCS, ulungiselelo olunjalo luyilo. Kukweli nqanaba apho kuthathelwe ingqalelo ukuba mingaphi na imisebenzi ekufuneka ibonelelwe, mangaphi amazibuko afanele ukubekwa, kwaye sisiphi na isakhono ekufuneka sibekwe phantsi. Kule nqanaba, kuyimfuneko ukukhokelwa yimigangatho (ISO / IEC 11801, EN 50173, ANSI / TIA / EIA-568-A). Enyanisweni, ngeli nqanaba ukuba amandla omda womnatha owenziweyo anqunywe.
Izibonelelo zekhebula
Kweli nqanaba, zonke iintambo zentambo zibekwe ukuqinisekisa ukuhanjiswa kwedatha kwinethiwekhi yendawo. Iikhilomitha zentambo yobhedu ephothiweyo ngokwezibini. Amakhulu eekhilogram zobhedu. Isidingo sokufaka iibhokisi zekhebula kunye neetreyi - ngaphandle kwazo, ukwakhiwa kwenkqubo yekhebula ehleliweyo akunakwenzeka.
Amanqaku okufikelela
Ukubonelela ngeendawo zokusebenza kunye nokufikelela kwinethiwekhi, iindawo zokufikelela zifakiwe. Ukukhokelwa ngumgaqo wokunciphisa (enye yezona zinto zibalulekileyo ekwakhiweni kwe-SCS), loo manqaku abekwe ngobuninzi obudlula inani elincinci elifunekayo. Ngokufaniswa nomnatha womnatha wombane: iziseko ezininzi zikhona, uguquguqukayo ungasebenzisa indawo apho inethiwekhi enjalo ikhona.
Amanqaku okutshintsha, ukuthuma
Okulandelayo, eyona nto iphambili kwaye, njengokhetho, iindawo zokutshintsha eziphakathi zifakwe. Iikhabhinethi / iikhabhinethi ze-telecom zibekwe, iintambo kunye namachweba ziphawulwe, uxhulumaniso lwenziwa ngaphakathi kwendawo yokudibanisa kunye nakwi-node ye-crossover. Ilog yokutshintsha iqulunqwe, ethi ihlaziywe emva koko kubo bonke ubomi benkqubo yentambo.
Xa zonke izigaba zofakelo zigqityiwe, yonke inkqubo iyavavanywa. Iintambo ziqhagamshelwe kwisixhobo sothungelwano esisebenzayo, kwaye inethwekhi yakhiwe. Ukuthotyelwa kwe-bandwidth ye-frequency (isantya sothumelo) esibhengezwe kwi-SCS enikeziweyo ihlolwe, iindawo zokufikelela ezilungiselelwe zibizwa, kwaye zonke ezinye iiparitha ezibalulekileyo ekusebenzeni kwe-SCS zihlolwe. Zonke iintsilelo ezichongiweyo ziyapheliswa. Kuphela emva koku, inethiwekhi idluliselwa kumthengi.
Isixhobo sokuhambisa ulwazi silungile. Yintoni elandelayo?
Yintoni "ehlala" kwi-SCS?
Ngaphambili, idatha evela kwiinkqubo ezahlukeneyo, ezivaliweyo kwitekhnoloji kunye neeprothokholi zazo, zathunyelwa kwisiseko sentambo yothungelwano lwasekhaya. Kodwa iteknoloji yezoo kudala iphindaphindwe ngo-zero. Kwaye ngoku kwindawo yendawo kukho, mhlawumbi, yi-Ethernet kuphela eseleyo. I-Telephony, ividiyo evela kwiikhamera zokujonga, i-alamu yomlilo, iinkqubo zokhuseleko, idatha yemitha ye-utility, iinkqubo zokulawula ukufikelela kunye ne-intercom ehlakaniphile, ekugqibeleni - konke oku ngoku kuhamba phezulu kwe-Ethernet.
I-Smart intercom, inkqubo yokulawula ukufikelela kunye nesixhobo sokulawula kude
Siziphucula ngokupheleleyo izixhobo zokusebenza
Kwaye umbuzo uvela: ngophuhliso oluqhubekayo lwetekhnoloji, ngaba sisafuna zonke iinxalenye zeSCS yendabuko?
I-Hardware kunye nokutshintshwa kwesoftware
Lixesha lokuvuma into ecacileyo: ukutshintshwa kwe-hardware kwinqanaba lokudibanisa kunye neentambo ze-patch zigqithise ukusetyenziswa kwayo. Yonke into sele yenziwe kudala kusetyenziswa izibuko zeVLAN, kwaye abalawuli bahlela ngeengcingo kwiindawo zogcino nanini na kukho naluphi na utshintsho kubume bomsebenzi womnatha kukuphosa umva. Lixesha lokuba uthathe inyathelo elilandelayo kwaye uyeke iminqamlezo kunye neepatchcords.
Kwaye kubonakala ngathi yinto encinci, kodwa ukuba ucinga ngako, kuya kuba neenzuzo ezininzi kule nyathelo kunokuba utshintshe intambo yecandelo elilandelayo. Zigwebe ngokwakho:
- Umgangatho wesixhobo sokuhambisa umqondiso uya kwanda.
- Ukuthembeka kuya kwanda, kuba sisusa ababini kwabathathu abafowunelwa koomatshini kwinkqubo (!).
- Ngenxa yoko, uluhlu lokuhambisa umqondiso luya kwanda. Akubalulekanga, kodwa kunjalo.
- Ngequbuliso kuya kubakho indawo kwii-closets zakho. Kwaye, ngendlela, kuya kubakho ucwangco oluninzi apho. Kwaye oku sele konga imali.
- Iindleko zezixhobo ezisusiweyo zincinci, kodwa ukuba uqwalasela yonke imilinganiselo yokuphucula, ukugcinwa kwexabiso elihle kunokuqokelela.
- Ukuba akukho xhulumaniso olunqamlezayo, unokukrazula imigca yomxhasi ngokuthe ngqo phantsi kwe-RJ-45.
Kwenzekani? Siye sayenza lula inethiwekhi, sayenza yabiza ixabiso eliphantsi, kwaye kwangaxeshanye yaba buggy kwaye yalawuleka ngakumbi. Iinzuzo zizonke!
Okanye mhlawumbi, ngoko, ulahle enye into? π
Ifiber ye-Optical endaweni yocingo lobhedu
Kutheni sifuna iikhilomitha zentambo ezijijekileyo xa isixa sisonke solwazi oluhamba ngeengcingo ezishinyeneyo lunokusasazwa ngokulula ngosinga optical? Masifake i-8-port switch kwiofisi kunye ne-optical uplink kwaye, umzekelo, inkxaso ye-PoE. Ukusuka kwi-closet ukuya kwiofisi kukho i-fiber optic core enye. Ukususela ekutshintsheni kubaxhasi - i-wiring yobhedu. Ngexesha elifanayo, iifowuni ze-IP okanye iikhamera zokucupha zinokubonelelwa ngamandla ngokukhawuleza.
Kwangaxeshanye, ayisiyiyo kuphela intaphane yentambo yobhedu kwiitreyi zeelatisi ezintle ezisusiweyo, kodwa nemali efunekayo yokubeka bonke obu bukhazikhazi, bemveli be-SCS, iyagcinwa.
Kuyinyani, isikimu esinjalo ngandlelβ ithile siyaphikisana nombono wokubekwa kwezixhobo βezichanekileyoβ kwindawo enye, kwaye ukonga kwintambo kunye nokutshintsha kwezinto ezininzi ezinamazibuko obhedu kuya kuchithwa ekuthengeni iiswitshi ezincinci ngePoE kunye ne-optics.
Kwicala lomxhasi
Intambo yecala lomxhasi ibuyela kwixesha apho iteknoloji engenazintambo yayibukeka njengento yokudlala kunesixhobo esisebenzayo sokwenyani. "I-wireless" yanamhlanje iya kubonelela ngokulula ngezantya ezingekho ngaphantsi kwentambo ebonelela ngayo ngoku, kodwa iya kukuvumela ukuba ukhulule ikhompyuter yakho kuqhagamshelo oluzinzileyo. Ewe, i-airwaves ayikho i-rubber, kwaye ayiyi kukwazi ukuyigcwalisa ngokungapheliyo ngamashaneli, kodwa, okokuqala, umgama ukusuka kumxhasi ukuya kwindawo yokufikelela unokuba yincinci kakhulu (iimfuno zeofisi zivumela oku), kwaye okwesibini, kukho. sele sele iintlobo ezintsha zobuchwepheshe ezisebenzisa umzekelo, radiation optical (umzekelo, into ebizwa ngokuba Li-Fi).
Ngeemfuno zoluhlu ngaphakathi kweemitha ezi-5-10, okwaneleyo ukudibanisa abasebenzisi be-2-5, indawo yokufikelela inokuxhasa ngokupheleleyo ishaneli yegigabit, ixabiso elincinci kwaye lithembeke ngokupheleleyo. Oku kuya kugcina umsebenzisi wokugqibela kwiingcingo.
Ukutshintsha okubonakalayo S kunye ne-gigabit router wireless edityaniswe yintambo ye-optical patch
Kwixesha elizayo elingekude, elo thuba liya kubonelelwa ngezixhobo ezisebenza kwi-millimeter wave (802.11ad / ay), kodwa okwangoku, nangona isantya esisezantsi, kodwa sisafuneka kubasebenzi baseofisini, oku kunokwenziwa ngokwenene ngokusekelwe kwi-802.11 ac umgangatho.
Enyanisweni, kule meko indlela yokudibanisa izixhobo ezifana neefowuni ze-IP okanye iikhamera zevidiyo ziyatshintsha. Okokuqala, kuya kufuneka babonelelwe ngamandla ahlukeneyo ngobonelelo lombane. Okwesibini, ezi zixhobo kufuneka zixhase i-Wi-Fi. Nangona kunjalo, akukho mntu uyala ukushiya inani elithile leechweba zethusi kwindawo yokufikelela okokuqala. Ubuncinci ukuhambelana ngasemva okanye iimfuno ezingalindelekanga.
Ngokomzekelo, i-router engenazintambo , 802.11a/b/g/n, 802.11ac Wave 2, 4xGE RJ45, 1xSFP
Inyathelo elilandelayo lisengqiqweni, akunjalo?
Masingapheli apho. Masiqhagamshele iindawo zofikelelo ngentambo yefiber optic ene-bandwidth, masithi, iigigabhithi ezili-10. Kwaye masilibale nge-SCS yendabuko njengephupha elibi.
Iskimu siba lula kwaye sibe ntle.
Esikhundleni seemfumba zeekhabhinethi kunye neetreyi ezizaliswe ngekhebula lobhedu, sifaka ikhabhinethi encinci apho utshintsho olune-optical "dozens" "luhlala" kubo bonke abasebenzisi be-4-8, kwaye sandisa i-fiber kwiindawo zokufikelela. Ukuba kuyimfuneko, kwizixhobo ezidala unokubeka ezinye izibuko "zobhedu" ezongezelelweyo apha - aziyi kuphazamisa iziseko eziphambili nangayiphi na indlela.
