Ibhokisi le-fiber nap liyisitsha esincane esisetshenziselwa ukubamba nokuphatha iziphetho zekhebula le-fiber optic ngesikhathi sokuxhuma noma ukulungisa. Yilokho kanye igama elikushoyo - ibhokisi le-fiber nap eligcina imicu ye-fiber ihlanzekile, iphephile futhi iseduze nesandla, igwema uthuli noma umonakalo. Amabhokisi amaningi e-fiber nap afakwe isembozo kanye nezikhala zokuhlunga ikhebula, ngakho-ke umsebenzi uhlanzekile futhi uyashesha. Amanye amabhokisi anezembozo ezicacile noma i-foam inserts ukuze kuvikelwe okwengeziwe. Ama-fiber geek amba la mabhokisi emalabhorethri, izikhungo zenethiwekhi noma izindawo zasensimini. Ibhokisi elifanele linganciphisa ukubambezeleka okubizayo kanye nokukhokha ngokuvimbela amaphutha kanye nomonakalo. Ezindabeni ezizayo, thola ukuthi ungakhetha kanjani ibhokisi le-fiber nap elifanele futhi ulisebenzisele ukuphathwa kwekhebula okuthuthukisiwe kanye nokuhamba komsebenzi.

Ibhokisi le-fiber access terminal (FAT Box) lisebenza njengendawo ebalulekile yokuhlangana kwamanethiwekhi e-fiber optic, lapho izintambo ze-fiber zihlangana khona ukuze zixhumeke ezindaweni zokuhlala noma ezindaweni zebhizinisi. Ama-FAT asiza amaqembu enethiwekhi ukusungula, ukuhlola nokulungisa imigqa ye-fiber yonke endaweni eyodwa. Avikela iziphetho ze-fiber esimweni sezulu kanye nothuli, okugcina izixhumanisi ze-inthanethi ziqinile futhi zinamandla. Iningi lama-FAT litholakala ngaphandle, ngokuvamile ezigxotsheni noma ezindaweni ezihlanganisiwe ezifakwe odongeni. Amayunithi athile asekela amachweba e-fiber angaba ngu-24 noma angu-48, okwenza afaneleke kokubili imisebenzi emincane nemikhulu. Lapho abantu befisa ukufinyelela okuthembekile nokusheshayo, ama-FAT ayaletha. Okulandelayo, funda ukuthi ama-FAT asebenza kanjani empeleni, nokuthi kungani ebalulekile kumanethiwekhi anamuhla.

I-SFP imele i-Small Form-factor Pluggable futhi isebenza njengesixhumi samamojula enethiwekhi, asekela i-fiber kanye ne-copper. I-RJ45 copper SFP uhlobo lwe-SFP, kodwa ivumela izintambo ze-Ethernet ezijwayelekile, ngakho-ke ivumela ukushintsha kwe-fiber ukuxhumana namanethiwekhi ethusi. I-OLT SFP iyi-Optical Line Terminal SFP, ekhona ikakhulukazi ekusetshenzisweni kwe-fiber ukuya ekhaya noma ebhizinisini, ngokuvamile ku-telecom. Idlulisela ulwazi oluvela emahhovisi amakhulu kuya kubasebenzisi abaningi abakude. Uhlobo ngalunye lwenza indima yalo ekusizeni amanethiwekhi ukuthi asebenze kangcono, kodwa ngalinye lenza umsebenzi ohlukile. Lolu lokugcina luzobonisa ukuthi kufanele lisetshenziswe nini ngalinye.

I-ip68 ukungangenwa manzi isilinganiso sivumela idivayisi ukuthi ifakwe emanzini ajule ngokuphelele amamitha angu-1.5 isikhathi esingangemizuzu engama-30 ngaphandle kokulimala. Amafoni amaningi, amawashi ahlakaniphile, nama-earbud asebenzisa lesi silinganiso kulezi zinsuku, okusho ukuthi kuphephile ukuwasebenzisa emvuleni noma ngisho naseshaweni. Lesi silinganiso siphakathi kweziphezulu kakhulu ezitholakala emhlabeni wamagajethi, sinikeza isiqinisekiso kubathandi bezinto zangaphandle kanye namaqhawe e-workshop amanzi. Sigcina uthuli lungaphandle, ngakho idivayisi yakho ihlala isesimweni esingcono kunesisha isikhathi eside. Abahamba ngezinyawo, ababhukudi kanye nabathandi basogwini bafunga nge-IP68 ebavumela ukuthi bagcine ubuchwepheshe babo buseduze - ngaphandle kokukhathazeka. Hlola ukuthi kusho ukuthini lesi silinganiso nokuthi sibaluleke kangakanani kuwe.

I-MDU ku-FTTH imele i-Multi-Dwelling Unit njenge-fulethi complex kumanethiwekhi e-fiber-to-the-home. Ezimweni ezinjalo, imicu ye-fiber isuka endaweni yokungena iye kuyo yonke indawo yokuhlala, ihlinzeka wonke umuntu ohlala kuyo ukufinyelela ekuxhumekeni okusheshayo nokuqhubekayo. Lokhu kuyindlela esetshenziswa iningi lamafulethi nama-condo asemadolobheni, lapho izakhamuzi ziseduze khona. Ukuhlelwa kwe-MDU kunciphisa izindleko futhi kulondoloze ubuhle besakhiwo ngokuhlanganisa izingxenye zomzila we-fiber. Abahlinzeki bavame ukukhetha i-FTTH yama-MDU ukuze banikeze bonke abaqashi ukufinyelela okulinganayo ku-bandwidth ephezulu. Okulandelayo, sizohlola ngokujulile ukuthi ukuhlelwa kwe-MDU kusebenza kanjani, izingxenye ezikulezi zinhlelo, kanye nokubaluleka kwazo kubasebenzisi kanye nabaqhubi benethiwekhi.

Iseva ye-DHCP yabela amakheli e-IP kanye nezinye izinhlaka zokucushwa kwenethiwekhi kumadivayisi akunethiwekhi ukuze akwazi ukuxhumana namanye amanethiwekhi e-IP. Igcina isikhathi somsebenzisi njengoba ikhipha lezi zilungiselelo ngokuzenzakalelayo, ngakho-ke abantu akudingeki balungiselele idivayisi ngayinye ngesandla. Iseva ye-DHCP isebenza kahle emakhaya, ezikoleni nasemahhovisi amakhulu ngoba igcina izinto zilula futhi inciphisa amaphutha. Uma ifoni noma ikhompyutha entsha ingena kunethiwekhi, iseva ye-DHCP ikhetha ikheli le-IP layo bese isabalalisa olunye ulwazi olufana nesango kanye ne-DNS. Ama-router amaningi ane-DHCP ebhakiwe, okwenza ukusetha inethiwekhi kusheshe. Esigabeni esilandelayo, thola ukuthi i-DHCP isebenza kanjani kanye nokubaluleka kwayo.

Ingqikithi yebhokisi lokuqeda ifayibha ivame ukuba yipulasitiki noma insimbi, ngayinye ikhethelwe ukuqina nokuvikelwa ezindaweni zokuxhuma izintambo. Amabhokisi epulasitiki avame ukusebenzisa i-polycarbonate noma i-ABS, engamelani nokushaqeka futhi engabizi kakhulu. Amabhokisi ensimbi, njengalawo akhiwe ngensimbi noma i-aluminium, ahlinzeka ngesivikelo esingcono kakhulu kanye nokuqina okwandisiwe lapho efakwa ezindaweni ezidinga kakhulu. Wonke asiza ekuvikeleni izintambo zefayibha othulini, emanzini, nasemaqhubu. Amanye amabhokisi aze ahlanganise lezi zinto, esebenzisa isisekelo sensimbi esinesembozo sepulasitiki, ukuze afinyelele ibhalansi yentengo/yokusebenza. Ukukhetha izinto ezifanele kusekelwe endaweni yebhokisi, izinga lokusetshenziswa elilindelekile kanye nezidingo zokuvikela. Isigaba esilandelayo sihlanganisa indlela izinto ngazinye ezingafanelana ngayo nezidingo ezahlukene nokuthi yini okufanele uyicabangele ngaphambi kokukhetha eyodwa.

I-ADSS ne-OPGW ziyizinhlobo ezimbili ezivamile zezintambo ze-fiber optic ezisetshenziswa emigqeni yokudlulisa amandla. I-ADSS, noma ikhebula elizisekelayo le-All-Dielectric, lisebenza kahle kakhulu ngezinjongo ezingezona ezokuhambisa ugesi. I-OPGW, noma i-Optical Ground Wire, ihlanganisa i-fiber optics nentambo yokumisa, ihlinzeka ngokudluliselwa kwedatha kanye nokuvikelwa kombani. Zombili izintambo zisiza izinsiza ukuxhumana ngokushesha nokugcina ukuzinza. I-ADSS imisa emibhoshongweni engenansimbi, ngakho-ke ilungele izifunda ze-voltage ephezulu. I-OPGW ihamba phezu kwemibhoshongo futhi i-double isebenza njengentambo yesivikelo. Ukukhetha phakathi kwe-ADSS ne-OPGW kuvame ukuba yindaba yokucushwa kombhoshongo, izidingo zokuphepha, kanye nendawo etholakalayo. Isihloko esilandelayo sibala izinzuzo nezinkinga ezisobala zohlobo ngalunye.
