Isicelo seCable se-UTP LAN esebenzisa kuma-network ye-office.

Ukwenza ukubeka kwamacable yase-UTP (Unshielded Twisted Pair) yase-LAN (Local Area Network) okuphelele yilindlela eyinkulu yokwenza izindawo zokusebenza zezindabeni ezinamandla. Nangona izintechinoloji zokuhamba (Wi-Fi) zinika umphakathi wokuhamba, izindawo zokusebenza ezenziwe kahle zezindabeni eziphelele ngezimali eziningi—njengokusebenzisa ividiyo yokuqhubeka, ukubambisana kwe-cloud database, ukuthumela amafayili amaningi, nokuxhumana ngolwimi (VoIP)—zihlala ziyaphatha ngokuphelele emsebenzini wamacable okuphelele.

Ukubeka kwamacable yase-UTP okuphelele kufanele kusize ekunciphiseni i-lag, ukuncipha ukuphulwa kwe-packet, ukunika ubungakanani obuphelele be-data, nokubusa isibonelo sekuvumela ukuzivikela phakathi kwezindawo zokusebenza zezindabeni nezinto ezingenani zokusebenza.

1. Kungani i-UTP ephakathi kwemithambo yezinkampani iyaphakamisa amasite kwe-wireless kuphela

Kwimbono yezinkampani zokuzulazula, ukubhekana kuphela nezinkampani zokufinyelela kwe-wireless kusho ukuthi kuyabizwa ukugcina kwe-radio frequency (RF), ukuphupha kwesinyathelo kusuka emabhangeni wendawo yokusebenza, ukuphakama kwe-latenzi, nokuthi kunezinkinga zokuvikela. Ukwenza umkhakha wokuxhumeka we-UTP omuhle ukuthi kuyisivumelwano sokusebenza esikhulu:

• Ukuxhumeka okugcinwe kwe-bandwidth: Ngaphandle kwe-Wi-Fi, apho i-bandwidth ishared phakathi kwezinkampani zonke ezixhumekile kwindawo yokufinyelela, i-UTP ephakathi yezinkampani isinika indawo yonke yokusebenza ukuxhumeka okungafihli, okuphakathi kwe-full-duplex.

• Ukuphupha kwe-packet okuncane nokuphakama kwe-latenzi okuncane: Izinxhumo zokuxhumeka ngomthambo ziyasusa ukuphupha kwe-electromagnetic interference (EMI) nokuxhumeka kabusha kwe-packet, ekunikeza ukuthi izixhumo zokusebenza ngokushesha ziyasebenza ngokuphelele kwezixhumo zokubiza nge-VoIP nokubiza kwe-video.

• Ukuxhumeka kwe-Power over Ethernet (PoE): Amakhabhela e-UTP amasha kakhulu akhuthaza ukuthenga kanye nokukhala kwesikhathi esihle kusenziwa ngamakhabhela eyodwa, okuyisibonelo sokulungisa ukubeka amaphoni e-IP, amaphoyinti we-wireless, amakhamera wezokugcina, kanye nezilumkani zesibonelo ngaphandle kokubeka amaplaya wezokukhala.

2. Ukukhetha Ikhabhela Efanayo Ngokwesixoxo Sebureau

Ukukhetha ikhabhela efanayo iyadetermina ubude bekhaya le-network, ubude obukhulu besibandla, kanye nokunakekelwa kokukhula kwesikhathi esizayo ngaphandle kokufaka izindawo zokuphuma kwezindawo ezithile.

3. Imithombo yezinhlangano nezindlela zokusebenza ngokuphelele kwezindawo zokusebenza

Kufanele izinkampani zokubeka izihlakulo ziyasebenze ngokuphelele ngemithombo yezinhlangano yezihlakulo eziphathelene nasezweni, njengoko kuvumeka ngokwesibonelo TIA/EIA-568 kanti ISO/IEC 11801 , ukuze kubekwe ubuhle obuphelele nokuzimela kwezinhlangano zezindawo zokusebenza.

Izinto ezibalulekile zokwakha:

1. Isikhundu sezindawo zokusebenza (WAO): Isikhundu sokugqamisa esikwamanzi okanye esifundazweni lapho abasebenzi bakhubeka ngokusebenzisa izihlakulo ezisemthandleni. Izindlela zokusebenza ngokuphelele zivuma ukuthi kufanele kubekwe izihlakulo ezimbili zika-Cat6 noma ka-Cat6a ngasendaweni yonke (eyodwa yedatha, eyodwa yovocice/PoE).

2. Ukubeka izihlakulo zokuphambuka: Izihlathi zesiliva esisodwa zokusebenza kwe-UTP ezihambisa ngemithambo yezinkundla zokusebenza noma phansi kwemithambo eyadlulayo ekhaya lokusebenza kwi-Telecommunications Room (TR). Ukubambisana kwesikhathi sokuhamba kungafanele ukwenzeka ngaphezu kwe-90 meters, okusho ukuthi kufuneka kubekwe i-10 meters ukusebenzisa izihlathi zokubambisana.

3. Ukugcina kwe-Patch Panel: Ekhaya lokusebenza, izihlathi zesiliva esisodwa zihlanganiswa ngendlela enqinile kuma-patch panels (kakhulu zisebenzisa izinhloso zokuhlanganisa zama-T568B) ukusakaza ukuphatha nokuguqula amaporti ngokukhawuleza.

4. Izindlela zokusebenza eziphelele: Ukuchaza ngumbala nokuphatha izihlathi

Isiqondiso esingasizi kakhulu sokuphatha umkhosi wokusebenza kukuphatha izihlathi ngokwempilo. Ukusebenzisa izindlela zokuphatha eziphelele zikwenza ukuthi ukuphatha kwezinye izinto zisidwane futhi kusiza ukuthi ukuvumela ukuphatha kwezinye izinto kusenziwe ngokukhawuleza:

• Isimo sokuchaza ngumbala sesihlathi: Ukuchaza umbala wesihlathi ngokwesikhundla sokusebenza kusiza ukuthi ukubonisa kusenziwe ngokukhawuleza (isibonelo, umbala omncane wokusebenza kwe-workstation, umbala omnyama wokusebenza kwe-VoIP phones, umbala omncane wokusebenza kwe-security cameras/fire alarms, umbala omnyama wokusebenza kwe-Wi-Fi Access Points).

• Ukubambisana kwe-bend radius nokuzimela kwezihlathi: Ukugcina ubukhulu obuncane be-radius yomkhiqizi (ngokuvamile izikhathi ezingu-4 ububanzi bangaphandle bekhebula) kuvimbela ukuguqulwa komqhubi kanye nokwehla kokusebenza okubangelwa ukuhlanekezelwa kwe-pair yangaphakathi.

• I-Plenum (CMP) vs. I-Riser (CMR) Amajazi: Qinisekisa ukuthi ikhebula elihanjiswa ngemigudu yomoya noma uphahla lokuwela lihlangabezana nemithetho yendawo yokuphepha ngomlilo ngokusebenzisa amajazi okuvimbela ilangabi asePlenum-rated akhiqiza intuthu enobuthi obuncane lapho ishiswa.
