Izindawo zokugcina idatha zokuphelele ziyathola izinkinga ezingaphezulu kwezinhlobo zokuxhumana kwekhonkhele ngokwezinhlobo zokusebenza nezindawo. Ngokuphela kwezindawo zokugcina idatha ngokuphela kwezinhlobo zokuxhumana kwekhonkhele, amacable ayenkulu nokungafanele kwezinhlobo zokuxhumana kwekhonkhele ayakhiwa ngokugcina kwezicabhe, ayavimba ukulula kokuhamba kwamafutha, futhi ayasolwa ngokungafanele kwezinhlobo zokuxhumana kwekhonkhele ngokuphela kwezinhlobo zokuxhumana kwekhonkhele.
Ukufaka amacable ayokuqondisa i-Ethernet eyinkulu yokusebenza, ayagcina isigaba sokugcina (kubhekwa kahle ngamaphathi e-28 AWG noma e-30 AWG okungabikho amaphathi) ayisolvele lezi zibuko zokuphakama, isihlombe sokubona kwezinkampani ngokusebenza kwezinsuku zonke, nokuthuthukisa ukuphatha kwesikhumba sokugcina imithwalo.
1. Ukwenza Kwemithwalo: Amaphathi Okuzenzakalela Noma Amaphathi Okuphambana Kakhulu
Ukuchaza kwezinye izinhlobo zemaphathi okuzenzakalela nezokuphambana kakhulu kuyisibonelo sezinhlobo zemaphathi ezinhlangothi, izinhlobo zemaphathi, izinhlobo zemaphathi yezindawo zokuphambana, nokuthuthukisa kwezindawo zokuphambana.
Izinhlobo Zokuchaza Kwezinhlobo
| Ipharamitha | Amaphathi Okuzenzakalela (24 AWG) | Amaphathi Okuphambana Kakhulu (28 AWG) | Amaphathi Okuphambana Kakhulu Kakhulu (30 AWG) |
| Isibonelo Sezinhlobo | 24 AWG Okuzenzakalela / Okuphambana | 28 AWG Okuphambana Kakhulu | 30 AWG Okukhula Kakhulu Kwakho |
| Ukubhala Kwesibhakabhaka (OD) | ~5.8 mm – 6.5 mm | ~3.8 mm – 4.2 mm | ~2.8 mm – 3.2 mm |
| Ukuphakanyiswa Kwesibhakabhaka | Isibalo (100%) | ukuphakanyiswa kwe-33% ukuze kube 50% | Ukuphakanyiswa kwe-60% |
| Isibhakabhaka Sokubhala Sokugcina | 4x ukuze kube 8x Cable OD (~25mm–50mm) | 4x Ukubhala Ukuphakama Kwakho (~15mm–16mm) | 4x Ukubhala Ukuphakama Kwakho (~11mm–12mm) |
| Amasiko Okukhula Kwe-Flex | ~1,000 ku-3,000 amasiko | amasiko angaphezu kwe-10,000 okukhula kwe-dynamic | amasiko angaphezu kwe-20,000 okukhula kwe-dynamic |
| Isikhundla Sokusebenza Kwe-PoE | Kufika ku-90W (PoE++ / Type 4) | Kufika ku-60W–90W (Kufuneka kuchazwe ukuthi kuyizilingo) | Kufika ku-30W–60W (Isilingo sokugcina esincane) |
2. Amaphakathi Amanye Osebenzayo Okukhula Kwemithambo Yezinkampani
-
Amathambo Amanye Okukhula Kwemithambo: Imithambo yezinkampani eziphelele ayisebenzisa amathambo amaningi asebenzisa i-copper esikhulu kakhulu, okuyisiphumo sokuthi kubhekwa ngokuphambuka kwemithambo eminingi. Imithambo yezinkampani ezingakhiwa ngokukhula kakhulu iyasebenzisa amathambo amaningi asebenzisa i-copper amaningi kakhulu, okuyisiphumo sokuthi kubhekwa ngokuphambuka kwemithambo eminingi. Lokhu kusiza ukuthi amathambo amaningi akhululeka ngokuzihlukanisa noma kufanekile ngokukhula, kubhekwa ngokuphambuka kwemithambo eminingi.
-
Amajaketi Elibonakalayo Ngokukhula Kakhulu: Amajaketi e-PVC ezinkampani eziphelele ayabonakala ngokuthi "kubonakala ngokukhula kakhulu," kubhekwa ngokuphambuka kwemithambo eminingi futhi kubhekwa ngokuphambuka kwemithambo eminingi. Imithambo yezinkampani ezingakhiwa ngokukhula kakhulu iyasebenzisa i-thermoplastic elastomeric (TPE) okanye i-PVC ephumelelayo ekhulula kakhulu, okuyisiphumo sokuthi kubhekwa ngokuphambuka kwemithambo eminingi futhi kubhekwa ngokukhula kakhulu.
-
Amabuthu Amanye Okukhula Kakhulu Okungafanele Ukubhekwa Ngokuphambuka Kwemithambo: Indawo apho imithambo yezinkampani iyafika ku-RJ45 yiyindawo eyisiphumo sokuthi kubhekwa ngokuphambuka kwemithambo eminingi. Imithambo yezinkampani ezingakhiwa ngokukhula kakhulu iyasebenzisa amabuthu amaningi okukhula kakhulu okungafanele ukubhekwa ngokuphambuka kwemithambo eminingi, nokubhekwa ngokuphambuka kwemithambo eminingi, okuyisiphumo sokuthi kubhekwa ngokuphambuka kwemithambo eminingi futhi kubhekwa ngokuphambuka kwemithambo eminingi (MACs).
3. Iziphakade zokugcina imvula nezindawo kumaphakethi amaningi
Kumaphakethi we-server wasezindaweni zezinhlangano nezinkampani zokugcina umphakathi (ToR), umkhondo wemikhili wokubhala kuyisiphumo sokusebenza kwemithambo yezinhlangano.
Iphakethi yemikhili yomthambo wokusebenza (Ukungabonakali kwezinye izinsiza zokuphuma): > Umthambo omkhulu uphatha indawo esebenzayo kumaphakethi, ukuvimba isizinda sokuphuma esingaphezu kwe-50%.
Iphakethi yemikhili yomthambo wokuflexa kakhulu (Ukuvimba okuhlelwa kahle): > Umthambo ongafanele kakhulu uvimba izindlela zokubhala ngokwesibhakabhaka nezokuzungezela, ukuvimba isizinda sokuphuma esingaphezu kwe-30%+.
Izidingo Zokusebenza
-
Isizinda sokuphuma esivimbiwe: Amaphakethi amaningi wemikhili yomthambo wokuflexa kakhulu wokubhala ngokwesibhakabhaka nezokuzungezela ayisebenza kwe-50% kancane kwezindawo zokubhala, ukunciphisa ukungabonakali kwezinhlangano nezinkinga zokugcina imvula.
-
Ukugcina okunzima futhi ukubonakalisa ngokulinganayo: Abatekinisi bangafuna amaphoyinti amaningi ngokushesha ngaphandle kokuchitha amaphoyinti amaningi, ukukhupha ukuthi kubhekwa kwezinkampani eziningi kusukela kwezinkampani ezingaphansi.
-
Ukuphula Kwezinkinga Zokugcina Umkhawulo: Umthwalo omncane wezihluzi ukuphula umthelela wokugcina kwezindawo zokugcina, izihluzi zokugcina zezibhodi zokugcina, nezindawo zokugcina zezinkampani zokusebenza.
4. Imithombo Yezixhobo Nezindlela Zokusebenza
Nakuba izihluzi zokugcina zezinkampani zezifunda eziyisikhathi eside zinamathuba amaningi okusebenza ngokomoya, abasebenzi bezinhlangano zokusebenza kufuneka bafunde imithombo yezixhobo ye-TIA ne-ISO ngokuhambisana nokuphula kwesikhathi sokusebenza nokusebenza kwe-Power over Ethernet (PoE).
Imithombo Yezixhobo Ye-TIA-568.2-D
Imithombo ye-ANSI/TIA-568.2-D iyavumela izihluzi zokugcina ze-28 AWG, noma kunjalo kunezimithombo zokusebenza ezithile:
-
Ukuphula Kwemithombo Yezixhobo (Ukuphulisa): Ngoba izihluzi zezinkampani ze-28 AWG zinamathuba amaningi okuphula kwezixhobo zokugcina nezixhobo zokugcina zezinkampani ze-24 AWG, kufuneka kubhekwe ukuphulisa kwezixhobo zokugcina.
-
Umgcino Wokuphula Kwesikhathi: Ukuphakamisa kwezinkinga zokugcina (ikhabhela yasehorizontali + amapatch cord) kufanele kuchazwe uma kusebenziswa i-patch cord esine 28 AWG. Isibonelo, uma kusebenziswa i-patch cord esine 10 meters, ukuphakamisa kwezinkinga zokugcina zokudala kufanele kuchazwe ngokulinganayo ukuze kubuyiselwe isikhundla sokusebenza sokugcina esine 100-meter.
-
Amaphuzu we-Power over Ethernet (PoE): Ngokwesibonelo sezinkambu zokuphakama kwezihlangothi ezincinci, izindlela zika-TIA zizimisele ukuthi amaphuzu amancane (ngokuvamile amakhabhela angu-12 ku-24 ngalokho) akhethwe uma kusolwa i-PoE engeyinkulu (njengokuthi i-60W noma i-90W ye-IEEE 820.3bt Type 3/4) ukuze kungavunyelwe ukuphakama kwesikhathi.
