Njengoba umphakathi wanamuhla uthuthuka, amanethiwekhi abe yingxenye ebalulekile yokuphila kwansuku zonke, futhi ukudluliswa kwesignali yenethiwekhi kuncike kuzintambo zenethiwekhi (ezivamise ukubizwa ngokuthi izintambo ze-Ethernet). Njengenxanxathela yesimanje yezimboni olwandle, ubunjiniyela basolwandle nasolwandle buya ngokuya buzenzakalela futhi buhlakaniphe. Imvelo iyinkimbinkimbi kakhulu, ibeka izidingo eziphakeme esakhiweni sezintambo ze-Ethernet kanye nezinto zekhebula ezisetshenziswayo. Namuhla, sizokwethula kafushane izici zesakhiwo, izindlela zokuhlukanisa, nokulungiselelwa okubalulekile kwezintambo ze-Ethernet yasolwandle.
1.Ukuhlelwa Kwekhebula
(1).Ngokokusebenza Kokudlulisa
Amakhebuli e-Ethernet esivame ukuwasebenzisa ngokuvamile enziwa ngamapheya ekhondatha yethusi asontekile, aqukethe amakhondatha ethusi anemicu eyodwa noma eminingi, izinto zokuhlanganisa ze-PE noma ze-PO, ezisontekile ngamapheya, bese amapheya amane akhelwe abe ikhebula eliphelele. Ngokusekelwe ekusebenzeni, amamaki ahlukene ezintambo angakhethwa:
Isigaba 5E (CAT5E): Igobolondo langaphandle livamise ukwenziwa nge-PVC noma i-pololefin engenantuthu ephansi ye-halogen, enemvamisa yokudlulisela engu-100MHz kanye nesivinini esikhulu esingu-1000Mbps. Isetshenziswa kabanzi kumanethiwekhi asekhaya najwayelekile ehhovisi.
Isigaba 6 (CAT6): Isebenzisa izikhondatha zethusi zezinga eliphezulu kanyei-polyethylene ephezulu kakhulu (i-HDPE)I-insulation material, ene-separator yesakhiwo, ikhulisa umkhawulokudonsa ukuya ku-250MHz ukuze kudluliselwe okuzinzile.
Isigaba 6A (CAT6A): Imvamisa inyuka ibe ngu-500MHz, izinga lokudlulisela lifinyelela ku-10Gbps, ngokuvamile lisebenzisa i-aluminium foil ye-Mylar tape njengento evikelayo, futhi ihlanganiswe nokusebenza okuphezulu kwe-halogen-free-free sheath material ukuze isetshenziswe ezikhungweni zedatha.
Isigaba 7 / 7A (CAT7/CAT7A): Isebenzisa i-conductor yethusi engenawo umoya-mpilo engu-0.57mm, ipheya ngayinye ivikelwe ngeI-aluminium foil ye-Mylar tape+ i-braid yocingo lwethusi ethayiwe iyonke, ithuthukisa ubuqotho besignali futhi isekela ukudluliswa kwesivinini esikhulu esingu-10Gbps.
Isigaba 8 (CAT8): Isakhiwo siyi-SFTP enokuvikela okukabili (i-aluminium foil ye-Mylar tape yepheya ngalinye + umluko jikelele), futhi umgodla uvamise ukuba yimpahla ye-XLPO engavimbeli ilangabi eliphezulu, esekela isivinini esingafika ku-2000MHz no-40Gbps, ifanele ukuxhunywa phakathi kwemishini phakathi kwedatha.
(2). Ngokusho kweShielding Structure
Ngokusho kokuthi izinto zokuvikela zisetshenziswa esakhiweni, izintambo ze-Ethernet zingahlukaniswa zibe:
I-UTP (Ipheya Esontekile Engavinjiwe): Isebenzisa kuphela i-PO noma i-HDPE impahla yokufaka engenazo izivikelo ezengeziwe, izindleko eziphansi, ezifanele izindawo ezinokuphazamiseka okuncane kozibuthe kagesi.
I-STP (Ipheya Elisontekile Elivikelekile): Isebenzisa i-aluminium foil ye-Mylar tape noma i-copper wire braid njengento evikelayo, ithuthukisa ukumelana nokuphazamiseka, ifanele indawo eyinkimbinkimbi ye-electromagnetic.
Izintambo ze-Marine Ethernet zivame ukubhekana nokuphazanyiswa okunamandla kagesi, okudinga izakhiwo ezivikelayo eziphakeme. Ukucushwa okujwayelekile kuhlanganisa:
I-F/UTP: Isebenzisa i-aluminium foil ye-Mylar tape njengongqimba oluvikelayo lulonke, ifanele i-CAT5E ne-CAT6, evame ukusetshenziswa ezinhlelweni zokulawula ezingaphakathi.
I-SF/UTP: I-aluminium foil ye-Mylar tape + i-copper braid shielding engenalutho, ithuthukisa ukumelana kwe-EMI jikelele, okuvame ukusetshenziselwa amandla olwandle kanye nokudluliswa kwesignali.
I-S/FTP: Ipheya ngalinye elisontekile lisebenzisa i-aluminium foil ye-Mylar tape ukuze ivikeleke ngazinye, enesendlalelo sangaphandle somluko wentambo yethusi ukuze kuvikelwe yonke into, ebhangqwe nempahla ephezulu ye-XLPO ekwazi ukumelana nelangabi. Lesi yisakhiwo esivamile sezintambo ze-CAT6A nangaphezulu.
2. Umehluko Kuzintambo ze-Marine Ethernet
Uma kuqhathaniswa nezintambo ze-Ethernet ezisekelwe emhlabeni, izintambo ze-Ethernet zasolwandle zinokuhluka okucacile ekukhethweni kwezinto ezibonakalayo kanye nokwakheka kwesakhiwo. Ngenxa yemvelo yasolwandle enokhahlo—inkungu kasawoti ephezulu, umswakama ophezulu, ukuphazamiseka okunamandla kazibuthe, imisebe ye-UV enamandla, nokuvutha—izinto zekhebula kufanele zihlangabezane namazinga aphezulu okuphepha, ukuqina, nokusebenza kwemishini.
(1).Izidingo Ezijwayelekile
Izintambo ze-Marine Ethernet zivame ukuklanywa ngokuya nge-IEC 61156-5 kanye ne-IEC 61156-6. Ikhebula elivundlile ngokuvamile lisebenzisa amakhondaktha ethusi aqinile ahlanganiswe nezinto zokuhlanganisa ze-HDPE ukuze kuzuzwe ibanga elingcono lokudlulisela kanye nokuzinza; izintambo zokuchibiyela emagumbini edatha zisebenzisa amakhondatha ethusi avaleleke ane-PO noma i-PE ethambile ukuze kube lula umzila ezindaweni eziqinile.
(2).Ukuvinjelwa Komlilo kanye Nokumelana Nomlilo
Ukuze uvimbele ukusakazeka komlilo, izintambo ze-Ethernet zasolwandle zivame ukusebenzisa izinto ze-polyolefin ezingenantuthu ephansi ye-halogen-free-retardant (njenge-LSZH, XLPO, njll.) ukuze kushelwe, kuhlangatshezwane ne-IEC 60332 flame retardant, IEC 60754 (i-halogen-free), kanye namazinga e-IEC 61034 (izinga eliphansi lentuthu). Ezinhlelweni ezibucayi, i-mica tape nezinye izinto ezikwazi ukumelana nomlilo zengezwa ukuze zihlangabezane namazinga e-IEC 60331 okumelana nomlilo, okuqinisekisa ukuthi imisebenzi yokuxhumana iyagcinwa ngesikhathi sezigameko zomlilo.
(3). Ukumelana Nowoyela, Ukumelana Nokugqwala, kanye Nokwakheka Kwezikhali
Emayunithi angaphesheya kwezilwandle njengama-FPSO nama-dredger, izintambo ze-Ethernet zivame ukuvezwa kuwoyela nemithombo yezindaba ebolayo. Ukuze kuthuthukiswe ukuqina kwe-sheath, kusetshenziswa izinto ezixhumene ne-polyolefin sheath (SHF2) noma izinto ezimelana nodaka ze-SHF2 MUD, ezihambisana namazinga okumelana namakhemikhali e-NEK 606. Ukuze kuqhutshekwe kuthuthukiswe amandla okusebenza, izintambo zingagqunywa nge-galvanized steel wire braid (GSWB) noma i-copper wire braid (TCWB), ehlinzeka ngokuminyanisa namandla aqinile, kanye nesivikelo sikagesi ukuze kuvikelwe ubuqotho besignali.
(4). Ukumelana ne-UV kanye nokusebenza kokuguga
Izintambo ze-Marine Ethernet zivame ukuchayeka elangeni eliqondile, ngakho-ke izinto ze-sheath kumele zibe nokuvikeleka okuhle kwe-UV. Ngokuvamile, i-polyolefin sheathing enezithasiselo ezimelana ne-UV emnyama isetshenziswa futhi ihlolwe ngaphansi kwezindinganiso zokuguga ze-UL1581 noma ze-ASTM G154-16 ze-UV ukuze kuqinisekiswe ukuzinza ngokomzimba nempilo yesevisi eyandisiwe ezindaweni eziphakeme ze-UV.
Kafushane, ungqimba ngalunye lwedizayini yekhebula ye-Ethernet yasolwandle iboshelwe ekukhethweni ngokucophelela kwezinto zekhebula. Izikhondatha zethusi zekhwalithi ephezulu, izinto zokufakwa kwe-HDPE noma ze-PO, i-aluminium foil ye-Mylar tape, i-copper wire braid, i-mica tape, i-XLPO sheath material, kanye nezinto ze-SHF2 zesheath ndawonye zakha isistimu yekhebula yokuxhumana ekwazi ukumelana nezindawo zasolwandle ezinonya. Njengomphakeli wezinto zekhebula, siyakuqonda ukubaluleka kwekhwalithi yezinto ezibonakalayo ekusebenzeni kwayo yonke ikhebula futhi sizibophezele ekunikezeni izixazululo zezinto ezibonakalayo ezinokwethenjelwa, eziphephile, nezisebenza kakhulu ezimbonini zasolwandle nezisogwini.
