Ndibhala isikhokelo esipheleleyo malunga neeFiber Termination Boxes. IFiber Termination Box, okanye iFTB, isetyenziswa kwiinethiwekhi ze-fiber optic ukuphelisa iintambo nokubonelela ngonxibelelwano. Kodwa andiqinisekanga ngokupheleleyo ngazo zonke iinkcukacha. Makhe ndicinge ngale nyathelo ngenyathelo.

Okokuqala, kufuneka ndichaze ukuba yintoni Ibhokisi yokuphelisa ifayibha yiyo. Mhlawumbi qala ngenkcazelo esisiseko. Emva koko, mhlawumbi uchaze injongo yayo. Kutheni ibalulekile kwiinethiwekhi ze-fiber optic? Mhlawumbi ikhusela iifayibha kwaye ivumela ukuhlanganiswa kunye nokudityaniswa kwazo. Kodwa kufuneka ndiyiqonde kakuhle loo nto.

Okulandelayo, izinto ezibalulekileyo. Iitreyi ze-Splice, ii-adapters, izihlanganisi, ii-ports, iindawo zokungena kwi-cable, mhlawumbi i-mounting bracket. Iitreyi ze-Splice zibamba ii-splices, akunjalo? Ii-adapters zinokuba zezokudibanisa iintlobo ezahlukeneyo zezihlanganisi. Izihlanganisi ezifana ne-SC, i-LC, i-ST... Ndifanele ndizidwelise ezo. Ii-ports zilapho iintambo zingena khona ebhokisini. Izihlanganisi zokufakela.

Iintlobo zeebhokisi zokuphelisa iifayibha. Kusenokubakho ulwahlulo olwahlukeneyo. Mhlawumbi ngokusekwe kwindawo yokufakela: ngaphakathi nangaphandle. Ezangaphandle kufuneka zikhuseleke kwimozulu. Umthamo: inani leefayibha ezinokuzibamba, njenge-12, 24, 48. Uyilo: zifakelwe eludongeni, zifakelwe kwirakhi, idesktop. Mhlawumbi zahlukile ngokusekwe kwiintlobo zekhonkco ezizixhasayo. Kufuneka zigubungele zonke ezi ntlobo.

Inkqubo yokufaka. Amanyathelo abandakanyekayo ekufakeni iibhokisi zokuphelisa ifayibha. Okokuqala, ukucwangcisa indawo yokuzibeka. Emva koko, ukulungisa iintambo, ukuzisusa, ukudibanisa iintambo kwiitreyi ze-splice. Ukulungelelanisa iintambo, ukuqinisa iintambo, ukuvavanya uqhagamshelo. Mhlawumbi khankanya izixhobo ezifunekayo, ezifana nee-strippers, ii-splicers, izixhobo zokuvavanya.

Izicelo. Zisetyenziswa phi iiFiber Termination Boxes? Iinethiwekhi zeTelecom, amaziko edatha, iinethiwekhi zamashishini, iiCATV, useto lwemizi-mveliso. Isicelo ngasinye sinokuba neemfuno ezahlukeneyo. Umzekelo, amaziko edatha afuna uxinano olukhulu, iindawo zoshishino zifuna iibhokisi eziqinileyo.

Iingenelo. Ukukhuselwa kwiimeko zokusingqongileyo, ulungelelwaniso, ukukwazi ukukhulisa, ukulula kokugcinwa. Mhlawumbi ungakhankanya ukonga imali ngokunciphisa iingozi zomonakalo kwiintambo.

Iingcebiso zokulungisa. Ukuhlolwa rhoqo, ukucoca izihlanganisi, ukulebhelisha ngokufanelekileyo, uxwebhu, ukuphucula xa kuyimfuneko. Oku kunceda ekugcineni ukusebenza kunye nokusombulula iingxaki.

Ukusombulula iingxaki eziqhelekileyo. Ukulahleka kwesiginali kunokubangelwa zizihlanganisi ezingcolileyo okanye izihlanganisi ezimbi. Ukonakala okubonakalayo kwibhokisi okanye kwiintambo. Iingxaki zoqhagamshelo zisenokuba ngenxa yezihlanganisi ezingahambelaniyo okanye ukufakwa okungafanelekanga. Ukonakala kwendalo okufana nokungena kwamanzi kwiiyunithi zangaphandle.

Ukukhetha iibhokisi zokuphelisa iFiber ezifanelekileyo. Izinto ezifana nomthamo, indawo engqongileyo, uhlobo lwesixhumi, ukukwazi ukukhulisa, ukuthobela imigangatho. Kufuneka kuhambelane nebhokisi neemfuno zenethiwekhi.

Isiphelo. Shwankathela ukubaluleka kweeFiber Termination Boxes ekulawuleni iinethiwekhi zefiber ngokufanelekileyo.

Linda, kukho into endiyiphosileyo? Mhlawumbi ngumgaqo osebenzayo? Isebenza njani kanye kanye ibhokisi kwinethiwekhi? Kwakhona, mhlawumbi faka imizobo okanye imifanekiso, kodwa ekubeni oku kubhalwe kuphela, mhlawumbi chaza isakhiwo. Kwakhona, amanyathelo okhuseleko ngexesha lokufakwa? Okanye ukuthobela imigangatho. Mhlawumbi khankanya imigangatho ye-IEC okanye yeTelcordia.

Ndifuna ukujonga ukuba zonke izinto zigutyungelwe na. Ii-splice trays, ii-adapters, izihlanganisi, ii-ports, kunye nokuqhoboshela.
Iintlobo: ngaphakathi/ngaphandle, umthamo, uyilo.
Amanyathelo okufakela: cwangcisa, lungisa iintambo, dibanisa, hlela, khusela, vavanya.
Izicelo: ii-telecom, amaziko edatha, njl. Iingenelo: ukhuseleko, ulungelelwaniso, ukukwazi ukukhulisa ulwazi.
Ulondolozo: hlola, coca, faka ilebheli. Ukusombulula iingxaki: ukulahleka kwesiginali, umonakalo, iingxaki zonxibelelwano.

Ndicinga ukuba oko kuphelele. Mhlawumbi sikhankanye nokudibanisa i-fusion vs ukudibanisa oomatshini? Okanye ngaba oko kuneenkcukacha ezininzi? Mhlawumbi kufakelwe. Kwakhona, iintlobo zeetreyi zokuqhawula - mhlawumbi zinokuba zezokudibanisa okanye zokudibanisa oomatshini. Kwakhona, iintlobo ezahlukeneyo zeendawo zokungena ngentambo, njengee-glands zeebhokisi zangaphandle.

Enye into, umahluko phakathi kokuphela kwento kunye nokusasazwa. Ngaba ibhokisi yokuphela kwento iyafana nebhokisi yokusasazwa? Mhlawumbi cacisa loo nto. Ukuphela kwento kukwamanqaku okuphela, ukusasazwa kwemiqondiso yokwahlulahlula. Kodwa mhlawumbi kwezinye iimeko zisetyenziswa ngendlela efanayo. Kufuneka ulumke apha.

Kwakhona, iinkalo zolawulo lwefayibha ngaphakathi kwebhokisi, njengokhuseleko lwe-bend radius, ukugcinwa kwe-slack. Ezi zibalulekile ukuthintela ukulahleka kwesiginali. Ngoko ke kwicandelo lezinto, khankanya ukuba ibhokisi ilawula ukugoba kwefayibha kwaye igcina ifayibha egqithisileyo.

Kwinkqubo yokufakela, qinisekisa ukuba irediyasi yokugoba efanelekileyo igcinwa. Ngexesha lokulungisa, jonga ukuba akukho nakuphi na ukugoba okuqinileyo.

Isigaba sovavanyo: ukusebenzisa i-OTDR okanye iimitha zamandla ukujonga ukulahleka. Mhlawumbi khankanya oko.

Ndicinga ukuba ndinoludwe oluhle. Ngoku, yakha ibe ngamacandelo anezihloko. Qinisekisa ukuba inxalenye nganye ihamba ngendlela efanelekileyo. Qala ngenkcazo nenjongo, uze emva koko ube neenxalenye, iintlobo, ukufakelwa, usetyenziso, iingenelo, ukugcinwa, ukusombulula iingxaki, iikhrayitheriya zokukhetha, isiphelo.

Ziphephe iilwimi zobugcisa apho kunokwenzeka, kodwa ezinye ziyafuneka. Cacisa amagama afinyeziweyo afana ne-FTTx (iFiber ukuya ku-x). Linda, kwii-applications, i-telecom isebenzisa i-FTTx, ngoko mhlawumbi yandisa loo nto.

Kwakhona, kwiintlobo ngeentlobo, mhlawumbi khankanya idome xa kuthelekiswa ne-flat type yangaphandle? Okanye ingaba loo nto icacile kakhulu. Mhlawumbi namathela kwiindidi eziphambili.

Jonga naziphi na iingcamango eziphosakeleyo. Umzekelo, iFiber Termination Box vs patch panel. Ipatch panel luhlobo lwebhokisi yokuphelisa? Okanye yahlukile. Mhlawumbi ipatch panel isetyenziswa kumaziko edatha kwiinxibelelwano ezininzi, ngelixa i-FTB isetyenziswa ngakumbi ekuphelisweni kwentsimi. Cacisa oko ukuba kuyimfuneko, kodwa mhlawumbi kungaphaya komlinganiselo.

Kulungile, ndicinga ukuba ndinesakhiwo esiqinileyo. Ngoku, bhala icandelo ngalinye ngokucacileyo, uqinisekise ukuchaneka. Qiniseka ukuba ucacisa amagama, unike imizekelo, kwaye ugcine ulwimi lufikeleleka. Ziphephe iimpazamo ezifana nokudideka kweefayibha zemowudi enye kunye nemowudi ezininzi ngaphandle kokuba zifanelekile. Ekubeni isikhokelo simalunga nebhokisi ngokwayo, mhlawumbi akufuneki ujonge kwiintlobo zeefayibha ngaphandle kokuba zichaphazela ukhetho lwe-FTB.

Jonga kabini amanyathelo okufakela ukuze ubone ukuba alungile na. Cwangcisa indawo ngokujonga indawo kunye nokufikeleleka. Lungisa iintambo ngokuzisusa, ukuzicoca, ukuzidibanisa. Sebenzisa iitreyi ze-splice, qinisa iintambo ezineentambo, vala izinto ezingaphakathi ukuze zisetyenziswe ngaphandle. Vavanya uqhagamshelo ngezixhobo ezifanelekileyo.

Izicelo: kwi-telecom yokudibanisa izakhiwo zabathengi, kwiziko ledatha lokudibanisa izixhobo, iinethiwekhi zeshishini zocingo lwangaphakathi, i-CATV yokusasaza imiqondiso yevidiyo, imboni kwiindawo ezinobungozi.

Iingenelo: ukhuseleko lomzimba, ulungiselelo olucwangcisiweyo, olunokwandiswa ngokongeza iifayibha ezingaphezulu, ukugcinwa okulula ngeeports ezineelebheli.

Ulondolozo: hlola umonakalo, coca izihlanganisi ngezixhobo ezifanelekileyo, ilebheli ngokuchanekileyo, ubhale utshintsho, uphucule xa usanda.

Ukusombulula iingxaki: jonga izihlanganisi, izihlanganisi, umonakalo obonakalayo, izitywino zokusingqongileyo.

Ukukhetha: umthamo ohambelanayo, cinga ngeendawo zangaphakathi/zangaphandle, iintlobo zezihlanganisi ezifunekayo, ukwandiswa kwexesha elizayo, ukuthobela imigangatho efana ne-IEC 61754 okanye iTelcordia GR-771.

Ewe, oko kubonakala ngathi kugubungela yonke into. Ngoku, yidibanise yonke into kwisikhokelo esihambelanayo, usebenzisa izihloko ezicacileyo kunye neenkcazo ezimfutshane. Qinisekisa ukuba icandelo ngalinye linolwazi kwaye liphendula imibuzo enokubakho umfundi anokuba nayo. Kuphephe ukuphindaphinda, qinisekisa ukuba kukho utshintsho oluhamba kakuhle phakathi kwamacandelo. Jonga naziphi na iimpazamo zobugcisa kwaye uzilungise. Kulungile, mandibhale isikhokelo esipheleleyo ngoku.
