Njengoko uluntu lwangoku lukhula, uthungelwano lube yinxalenye ebalulekileyo yobomi bemihla ngemihla, kwaye ukuhanjiswa komqondiso womnatha kuxhomekeke kwiintambo zenethiwekhi (ezibizwa ngokuba ziintambo ze-Ethernet). Njengomzi mveliso wanamhlanje ohambahambayo elwandle, ubunjineli baselwandle nangaselunxwemeni busiya buzenzela kwaye bukrelekrele. Indawo engqongileyo inzima ngakumbi, ibeka iimfuno eziphezulu kwisakhiwo seentambo ze-Ethernet kunye nezixhobo zentambo ezisetyenzisiweyo. Namhlanje, siza kwazisa ngokufutshane iimpawu zolwakhiwo, iindlela zokuhlela, kunye nolungelelwaniso lwemathiriyeli ephambili yeentambo ze-Ethernet zaselwandle.
1.Ukuhlelwa kweCable
(1).NgokweNtsebenzo yoThutho
Iintambo ze-Ethernet esiqhele ukuzisebenzisa ngokuqhelekileyo zenziwe nge-copper conductor twisted pair structures, eziqulathe ii-conductor zobhedu ezilodwa okanye ezinemisonto emininzi, izinto ze-PE okanye ze-PO zokugquma, eziphothiweyo ngazibini, emva koko izibini ezine zenziwe zibe yintambo epheleleyo. Ngokusekwe ekusebenzeni, amabakala ahlukeneyo eentambo anokukhethwa:
Udidi lwe-5E (CAT5E): I-sheath yangaphandle ngokuqhelekileyo yenziwe nge-PVC okanye i-halogen-free polyolefin ephantsi komsi, kunye ne-frequency transmission ye-100MHz kunye nesantya esiphezulu se-1000Mbps. Isetyenziswa kakhulu kuthungelwano lwasekhaya kunye neofisi jikelele.
ICandelo 6 (CAT6): Isebenzisa iikhondatha zobhedu ezikumgangatho ophezulu kunyei-polyethylene ephezulu yoxinaniso (HDPE)imathiriyeli yokugquma, enesahluli solwakhiwo, inyusa i-bandwidth ukuya kwi-250MHz yosasazo oluzinzile ngakumbi.
Udidi lwe-6A (CAT6A): Ukunyuka rhoqo ukuya kwi-500MHz, izinga lokudluliselwa lifikelela kwi-10Gbps, ngokuqhelekileyo isebenzisa i-aluminium foil ye-Mylar tape njengento yokukhusela ibini, kwaye idibaniswe ne-high-performance low-low-low-smoke-free sheath material ukuze isetyenziswe kumaziko edatha.
Udidi 7 / 7A (CAT7/CAT7A): Isebenzisa i-0.57mm i-copper conductor engena-oksijini, isibini ngasinye sikhuselekileIfoyile yealuminium yeMylar tape+ I-braid yocingo yobhedu enkonkxiweyo iyonke, iphucula imfezeko yomqondiso kunye nokuxhasa i-10Gbps yokuhanjiswa kwesantya esiphezulu.
Udidi lwe-8 (CAT8): Ulwakhiwo yi-SFTP ene-double-layer shielding (i-aluminium foil ye-Mylar tape kwisibini ngasinye + i-braid jikelele), kunye ne-sheath ngokuqhelekileyo i-flame-retardant ye-XLPO ye-sheath material, exhasa ukuya kwi-2000MHz kunye ne-40Gbps yesantya, ifanelekile kumaziko aphakathi kwezixhobo kumaziko edatha.
(2). NgokweSakhiwo sokuKhusela
Ngokumalunga nokuba izixhobo zokukhusela zisetyenziswa kwisakhiwo, iintambo ze-Ethernet zinokwahlulwa zibe:
I-UTP (Isibini Esijikiweyo Esingakhuselekanga): Isebenzisa kuphela i-PO okanye i-HDPE imathiriyeli yokugquma ngaphandle kokukhuselwa okongeziweyo, ixabiso eliphantsi, elilungele iindawo ezinokuphazamiseka okuncinci kwe-electromagnetic.
I-STP (Isibini esijikiweyo esiKhuselweyo): Isebenzisa i-aluminium foil ye-Mylar tape okanye i-copper wire braid njengezinto ezikhuselayo, ukwandisa ukuchasana nokuphazamiseka, ngokufanelekileyo kwiindawo ezinzima ze-electromagnetic.
Iintambo ze-Ethernet zaselwandle zihlala zijongana nokuphazamiseka okunamandla kwe-electromagnetic, ezifuna izakhiwo ezikhuselayo eziphezulu. Ulungelelwaniso oluqhelekileyo luquka:
I-F / UTP: Isebenzisa i-aluminium foil i-Mylar tape njengoluhlu olukhuselayo olupheleleyo, olufanelekileyo kwi-CAT5E kunye ne-CAT6, esetyenziswa ngokuqhelekileyo kwiinkqubo zokulawula kwibhodi.
I-SF / UTP: I-aluminium foil ye-Mylar tape + i-copper braid shielding shielding, ephucula ukuchasana kwe-EMI ngokubanzi, esetyenziswa ngokuqhelekileyo kumandla olwandle kunye nokuhanjiswa komqondiso.
I-S/FTP: Isibini ngasinye esijijekileyo sisebenzisa i-aluminium foil ye-Mylar ye-tape yokukhusela umntu ngamnye, kunye nomgca wangaphandle we-wire braid yokukhusela yonke into, edityaniswe ne-XLPO ephezulu engagungqiyo kwi-sheath material. Esi sisakhiwo esiqhelekileyo se-CAT6A nangaphezulu kweentambo.
2. Umahluko kwiiCables ze-Marine Ethernet
Xa kuthelekiswa neentambo ze-Ethernet ezisekelwe kumhlaba, iintambo ze-Ethernet zaselwandle zineeyantlukwano ezicacileyo ekukhethweni kwezinto eziphathekayo kunye noyilo lwesakhiwo. Ngenxa yemekobume erhabaxa yaselwandle-inkungu ephezulu yetyuwa, ukufuma okuphezulu, ukuphazamiseka okunamandla kwe-electromagnetic, imitha ye-UV enzulu, kunye nokutsha-izixhobo zentambo kufuneka zihlangabezane nemigangatho ephezulu yokhuseleko, ukuqina, kunye nokusebenza koomatshini.
(1).IiMfuno eziMgangatho
Iintambo ze-Marine Ethernet zihlala ziyilwe ngokwe-IEC 61156-5 kunye ne-IEC 61156-6. I-Horizontal cabling isebenzisa ii-conductor zobhedu eziqinileyo ezidityaniswe nezinto zokugquma i-HDPE ukuphumeza umgama ongcono wothumelo kunye nokuzinza; iintambo zokubopha kumagumbi edatha zisebenzisa iikhondaktha zobhedu ezixineneyo ezine-PO okanye i-PE yokugquma ukuze kube lula ukuhamba kwiindawo ezixineneyo.
(2) .UkuBuyiswa komlilo kunye nokuNxhathisa uMlilo
Ukuthintela ukusasazeka komlilo, iintambo ze-Ethernet zaselwandle zihlala zisebenzisa i-halogen-free flame-retardant polyolefin materials (ezifana ne-LSZH, i-XLPO, njl.) ukwenzela ukuba i-sheathing, ukuhlangabezana ne-IEC 60332 i-flame retardant, i-IEC 60754 (i-halogen-free), kunye ne-IEC 61034 yomsi ophantsi. Kwiinkqubo ezibalulekileyo, i-mica tape kunye nezinye izinto ezichasene nomlilo zongezwa ukuhlangabezana nemigangatho ye-IEC 60331 yokumelana nomlilo, ukuqinisekisa ukuba imisebenzi yonxibelelwano igcinwa ngexesha leziganeko zomlilo.
(3). Ukunyangwa kwe-oyile, ukuNchasa ukuRhakala, kunye noLwakhiwo lwe-Armoring
Kwiiyunithi ezingaselunxwemeni ezinje ngeeFPSO kunye needrodi, iintambo ze-Ethernet zihlala zivezwa kwioyile kunye nemithombo yeendaba eyonakalisayo. Ukuphucula ukuqina kwe-sheath, izixhobo ze-polyolefin sheath ezidibeneyo (SHF2) okanye izixhobo ze-SHF2 ze-MUD ezinganyangekiyo ziyasetyenziswa, zihambelana nemigangatho ye-NEK 606 yokuxhathisa imichiza. Ukuqhubela phambili ukomeleza amandla oomatshini, iintambo zinokuxhonywa ngentsimbi yentsimbi eyenziwe ngentsimbi (GSWB) okanye ibraid yocingo lobhedu enkonkxiweyo (TCWB), ibonelela ngoxinzelelo kunye namandla okuqina, kunye nesikhuselo sombane ukukhusela imfezeko yomqondiso.
(4). Ukuchasana kwe-UV kunye nokusebenza kokuguga
Iintambo ze-ethernet zaselwandle zihlala zisesichengeni sokukhanya kwelanga, ngoko ke izixhobo ze-sheath kufuneka zibe nokuxhathisa okugqwesileyo kwe-UV. Ngokuqhelekileyo, i-pololefin sheathing enekhabhoni emnyama okanye izongezo ze-UV-resistant isetyenziswa kwaye ivavanywa phantsi kwe-UL1581 okanye i-ASTM G154-16 imigangatho yokuguga ye-UV ukuqinisekisa ukuzinza komzimba kunye nobomi benkonzo eyandisiweyo kwiindawo eziphezulu ze-UV.
Isishwankathelo, yonke ingqimba yoyilo lwentambo ye-Ethernet yolwandle ibotshelelwe ngokusondeleyo ekukhethweni ngononophelo kwezixhobo zentambo. Iziqhubi zekopolo ezikumgangatho ophezulu, i-HDPE okanye izinto zokugquma ze-PO, ifoyile ye-aluminium ye-Mylar tape, i-copper wire braid, i-mica tape, imathiriyeli ye-sheath ye-XLPO, kunye ne-SHF2 imathiriyeli ye-sheath kunye zenza inkqubo yentambo yonxibelelwano ekwaziyo ukumelana nemekobume enzima yaselwandle. Njengomthengisi wezinto eziphathekayo, siyakuqonda ukubaluleka komgangatho wezinto eziphathekayo ekusebenzeni kwentambo yonke kwaye sizimisele ukubonelela ngezisombululo ezithembekileyo, ezikhuselekileyo, kunye neziphezulu zokusebenza kumashishini aselwandle kunye nolwandle.
