Cat5/5e, Cat6/6a, Cat7 le Cable ea Cat8: Tataiso e Phethahetseng

2025-02-26

Ke hloka tataiso e phethahetseng bakeng sa likhoele tsa Cat5/5e, Cat6/6a, Cat7, le Cat8. Seo ke se tsebang ka mekhahlelo ena. Nomoro e 'ngoe le e 'ngoe ea Cat e emela litlhaloso tse fapaneng bakeng sa likhoele tsa Ethernet, Li fapana ho latela lebelo, bandwidth, tšireletso, mohlomong le sebaka seo li ka fetisang data ka katleho.

Taba ea pele, ke lokela ho hlalosa sehlopha ka seng ka bonngoe. A re boneng. Cat5 e tsofetse, mohlomong e fihla ho 100 Mbps? Empa Cat5e e ntlafalitsoe, e tšehetsa ho fihlela ho 1 Gbps. Ebe Cat6 e ka etsa 1 Gbps libakeng tse telele, mohlomong 10 Gbps empa e le khutšoanyane. Cat6a e ekelitsoe, kahoo ts'ebetso e betere, mohlomong 10 Gbps ho feta limithara tse 100. Cat7 e sirelelitsoe, e lebelo le phahameng, empa e sebelisa lihokelo tse fapaneng? 'Me Cat8 ke ea litsi tsa data, lebelo le phahameng haholo empa e le libaka tse khutšoane.

Ema, ke hloka ho fumana lintlha tse tobileng hantle. E re ke hlahlobe memori ea ka. Cat5e ke 1 Gbps ho fihlela ho limithara tse 100. Cat6 e ka etsa 10 Gbps ho fihlela ho limithara tse 55. Cat6a e atolosa seo ho fihlela ho limithara tse 100 bakeng sa 10 Gbps. Cat7 e lekantsoe bakeng sa 10 Gbps ho fihlela ho limithara tse 100 'me mohlomong le maqhubu a phahameng. Cat8 e etselitsoe 25 kapa 40 Gbps ho fihlela ho limithara tse 30. Hape, tšireletso ke ntlha; mekhahlelo e phahameng e na le tšireletso e eketsehileng ho fokotsa tšitiso.

Hape ke lokela ho bolela dipharologanyo tsa kaho, jwalo ka UTP (separa se sothehileng se sa sireletswang) khahlano le STP (se sireletswang). Cat5e hangata ke UTP, ha Cat6a le ba ka hodimo ba ka nna ba sebedisa tshireletso. Cat7 e sebedisa dihokelo tsa GG45 kapa TERA, empa e ntse e tsamaellana le RJ45. Ema hanyane, na ho nepahetse? Mohlomong Cat7 hangata e sebedisa RJ45 empa e na le tshireletso e eketsehileng. Ka sebele Cat8 e sebedisa RJ45.

Ditshebediso le tsona di bohlokwa. Mohlala, Cat5e bakeng sa marangrang a lapeng, Cat6 bakeng sa diofisi, Cat7 bakeng sa diindasteri, le Cat8 bakeng sa ditsi tsa data. Ditjeo ke ntlha e nngwe; mekhahlelo e phahameng e bitsa tjhelete e ngata. Ho thibela nakong e tlang e ka ba taba ya ho nahana. Hape, bolelele ba thapo le hore na ke thapo e tiileng kapa e qabeletsoeng. Ho lokile, thapo e tiileng ke ya ho kenya tse tsitsitseng, e qabeletsoeng bakeng sa dithapo tsa patch.

Ke hloka ho hlophisa tataiso ka likarolo bakeng sa mofuta o mong le o mong oa thapo, litlhaloso tsa bohlokoa (lebelo, bandwidth, sebaka), tšireletso, lits'ebetso, le chate ea papiso. Ebe u kenyelletsa lintho tse lokelang ho nahanoa ka ho reka joalo ka litlhoko tsa ts'ebeliso, ho thibela bokamoso, tekanyetso, tikoloho (tšitiso ea lerata), le mofuta oa ho kenya (o tiileng khahlanong le o tsielehileng).

Ema hanyane, ke lokela ho hlahloba lebelo le sebaka se phahameng ka ho fetisisa. E re ke netefatse: Cat5e ke 1 Gbps ho 100 MHz ho feta 100m. Cat6 ke 1 Gbps ho fihlela ho 100m, 10 Gbps ho fihlela ho 55m. Cat6a ke 10 Gbps ho 500 MHz ho feta 100m. Cat7 ke 10 Gbps ho 600 MHz ho feta 100m, le Cat7a ho fihlela ho 1000 MHz. Cat8 ke 25/40 Gbps ho 2000 MHz ho fihlela ho 30m. Hape, Cat7 le 8 li na le litlhoko tse thata tsa tšireletso.

Ho kenyelletsa bandwidth (MHz) ho bohlokoa hobane seo se ama bokgoni ba phetiso ya data. Dihokelo: Cat8 e sebedisa RJ45, empa Cats tsa pejana di ka ba le mefuta e fapaneng ya tshireletso. Hape, ho tsamaellana le meralo ya motheo e seng e ntse e le teng. Mohlala, ho sebedisa Cat6a ka di-jack tsa Cat5e ho kanna ha se ke ha sebedisa bokgoni bohle.

Ke lokela ho bolela hore mekhahlelo e phahameng e tšehetsa li-bandwidth tse phahameng 'me ka hona li molemo bakeng sa marang-rang a lebelo le phahameng, empa e ka ba ho feteletseng bakeng sa ts'ebeliso ea mantlha. Hape, liphapang tsa 'mele tse kang botenya le radius e kobehileng. Cat6a e teteaneng ebile ha e tenyetsehe ho feta Cat5e.

Ha ho nahanoa ka theko, lintlha tse kang litlhoko tsa hona joale khahlanong le tsa nakong e tlang, tikoloho (indasteri e nang le tšitiso khahlanong le ea lapeng), le hore na ba hloka PoE (Matla holim'a Ethernet), ke lihlopha life tse phahameng tse ka tšehetsang hamolemo.

Ke hloka ho etsa bonnete ba hore tataiso e bonolo ho e utloisisa, e qoba puo e ngata haholo ea tekheniki, empa e ntse e fana ka tlhahisoleseling. Mohlomong tafole e khutšoanyane ea kakaretso qalong, ebe likarolo tse qaqileng. Hape, maemo a tloaelehileng a tšebeliso ho thusa babali ho etsa qeto ea hore na ba hloka eng.

Ema hanyane, ke lokela ho hlahloba hore na Cat7 e ananeloa ka maemo a TIA/EIA kapa hore na ke maemo a ISO. Hobane ka linako tse ling Cat7 ha e amoheloe haholo libakeng tse itseng. Cat6a le Cat8 li na le maemo a tloaelehileng haholoanyane. Eo e ka ba ntlha ea bohlokoa eo re lokelang ho e bua tlas'a lintlha tse nahanoang, joalo ka ho lumellana le maemo a teng.

Hape, dipharologanyo tsa ditjeo. Cat5e e theko e tlase, ebe Cat6, Cat6a, Cat7, Cat8 ke tsona tse turang ka ho fetisisa. Kahoo tekanyetso ke ntlha. Bakeng sa basebedisi ba bangata ba malapeng, Cat5e kapa Cat6 e lekane. Bakeng sa matlo a bohlale a nang le disebediswa tse ngata, mohlomong Cat6. Bakeng sa ditsi tsa data, Cat8.

Ho thella fatše e ka ba bothata ka likhoele tse sirelelitsoeng; haeba li sa thella hantle, ho thella ho ka baka mathata. Kahoo ho kenya likhoele tse sirelelitsoeng ho hloka mekhoa e nepahetseng.

Ka bokhutšoanyane, tataiso e lokela ho akaretsa litlhaloso tsa mofuta o mong le o mong oa cable, e li bapise, 'me e tataise' mali ho latela litlhoko tsa bona tse ikhethang: litlhoko tsa lebelo, sebaka, tikoloho, tekanyetso le merero ea kamoso.
