A'o tuputupu a'e le sosaiete fa'aonaponei, o feso'ota'iga ua avea ma vaega taua o le olaga i aso uma, ma o feso'ota'iga fa'ailoga e fa'alagolago i uaea feso'otaiga (e masani ona ta'ua o Ethernet cables). I le avea ai o se fa'alapotopotoga fa'aonaponei fa'aonaponei i le sami, enisinia o le gataifale ma atunu'u i fafo o lo'o fa'ateleina le otometi ma le atamai. O le siosiomaga e sili atu ona faigata, tuʻuina atu manaʻoga maualuga i luga o le fausaga o laina Ethernet ma mea faʻaoga uaea. I aso nei, o le a matou faʻaalia faʻapuupuu foliga faʻavae, metotia faʻavasegaina, ma faʻasologa o mea autu o laina Ethernet gataifale.
1.Cable Classification
(1) E tusa ai ma le Fa'asalalauga Fa'atinoga
O uaea Ethernet tatou te masani ona faʻaogaina e masani lava ona faia i le kopa kopa faʻapipiʻi paʻu paʻu, o loʻo i ai se tasi poʻo le tele-stranded kopa mea faʻapipiʻi, PE poʻo PO mea faʻapipiʻi, milo taitoalua, ona faʻapipiʻi ai lea i se uaea atoatoa. Faʻavae i luga o faʻatinoga, e mafai ona filifilia vasega eseese o uaea:
Category 5E (CAT5E): O le faaofuofu pito i fafo e masani lava ona faia i le PVC poʻo le maualalo o le asu halogen-free polyolefin, faʻatasi ai ma le faʻasalalauga faʻasalalau o le 100MHz ma le maualuga maualuga o le 1000Mbps. E fa'aaogaina lautele i fale ma ofisa lautele feso'otaiga.
Va'aiga 6 (CAT6): Fa'aaogā ta'avale kopa maualuga mapolyethylene maualuga (HDPE)mea insulation, faʻatasi ai ma se vavae faʻavae, faʻateleina le bandwidth i le 250MHz mo faʻasalalauga sili atu.
Category 6A (CAT6A): Fa'ateleina le fa'atele i le 500MHz, e o'o atu i le 10Gbps le fa'asalalauga, e masani ona fa'aogaina le pepa alumini Mylar tape e fai ma mea e puipui ai paga, ma tu'ufa'atasia ma mea fa'apipi'i e leai se asu asu e fa'aaoga i nofoaga autu o fa'amaumauga.
Category 7 / 7A (CAT7/CAT7A): Fa'aaoga le 0.57mm le okesene e leai se okesene ta'avale apamemea, ta'itasi pa'aga puipui ipepa alumini Mylar lipine+ u'amea fa'alava uaea 'apamemea, fa'aleleia le fa'amaoni fa'ailo ma lagolagoina le 10Gbps fa'asalalau maualuga.
Category 8 (CAT8): O le fausaga o le SFTP faʻatasi ai ma le talipupuni faʻalua-lua (aluminium foil Mylar tape mo paga taʻitasi + faʻapipiʻi atoa), ma o le faʻaofuofu e masani lava ona maualuga le mumu XLPO mea faʻapipiʻi, lagolago e oʻo atu i le 2000MHz ma le 40Gbps saoasaoa, talafeagai mo fesoʻotaʻiga vaʻavaʻa-meafaigaluega i nofoaga autu.
(2). E tusa ai ma le Shielding Structure
E tusa ai pe faʻaaogaina mea e puipuia ai i le fausaga, e mafai ona vaevaeina laina Ethernet i:
UTP (Unshielded Twisted Pair): Fa'aaogaina na'o le PO po'o le HDPE mea fa'apipi'i e leai se isi talipupuni, tau maualalo, talafeagai mo si'osi'omaga e itiiti fa'alavelave fa'aeletonika.
STP (Shielded Twisted Pair): Fa'aaoga le alumini pepa Mylar lipine po'o le uaea apamemea e fai ma mea e puipui ai, fa'aleleia le fa'alavelave fa'alavelave, talafeagai mo si'osi'omaga lavelave electromagnetic.
O laina Ethernet sami e masani ona feagai ma faʻalavelave eletise eletise, e manaʻomia ai le maualuga o le puipuiga. Fa'atonuga masani e aofia ai:
F/UTP: Fa'aaoga le pepa alumini Mylar lipine e fai ma fa'amaufa'ailoga lautele, talafeagai mo le CAT5E ma le CAT6, e masani ona fa'aogaina i luga ole va'aiga fa'atonu.
SF/UTP: Alumini pepa Mylar lipine + fa'alava fa'alava apamemea talipupuni, fa'aleleia le fa'ato'aga atoa o le EMI, e masani ona fa'aogaina mo le malosi o le gataifale ma fa'asalalauga fa'ailo.
S/FTP: E fa'aogaina e paga ta'itasi ta'itasi le alumini pepa Mylar lipine mo le talipupuni ta'ito'atasi, fa'atasi ai ma le fa'alava pito i fafo o le uaea apamemea mo le talipupuni atoa, fa'atasi ma mea maualuga XLPO fa'afu. Ole fausaga masani lea mo CAT6A ma luga ole uaea.
2. Eseesega i le Marine Ethernet Cables
Pe a faatusatusa i laina Ethernet e faavae i fanua, o laina Ethernet o le gataifale e manino le eseesega i le filifilia o meafaitino ma le mamanu fausaga. Ona o le faigata o le si'osi'omaga o le gataifale-maualuga le puao masima, maualuga le susu, malosi electromagnetic faʻalavelave, malosi faʻavevela UV, ma mu-e tatau ona ausia e mea uaea tulaga maualuga mo le saogalemu, tumau, ma le faʻaaogaina o masini.
(1). Tulaga Manaomia
E masani ona mamanuina uaea Ethernet sami e tusa ai ma le IEC 61156-5 ma le IEC 61156-6. E masani ona fa'aogaina e le fa'alava fa'asaga le ta'avale apamemea mautu fa'atasi ma mea fa'alumaina HDPE e maua ai le mamao sili atu ma le mautu; fa'apipi'i maea i totonu o potu fa'amatalaga e fa'aogaina ai ta'avale apamemea fa'alava ma fa'amalu malu PO po'o le PE mo le fa'afaigofieina o le ta'avale i avanoa va'ava'ai.
(2) .Afi Mu ma Tetee Afi
Ina ia taofia le salalau atu o le afi, e masani ona faaaoga e uaea Ethernet gataifale maualalo-asu halogen-saoloto afi polyolefin mea (e pei o le LSZH, XLPO, ma isi) mo sheathing, feiloai IEC 60332 mu retardant, IEC 60754 (halogen-saoloto), ma IEC 61034 (asu maualalo) tulaga faatonuina. Mo faiga faʻapitoa, faʻapipiʻi mica tape ma isi mea e faʻafefe afi e faʻamalieina tulaga faʻataʻatia o le IEC 60331 afi, faʻamautinoaina o loʻo faʻatumauina galuega tau fesoʻotaʻiga i taimi o faʻalavelave afi.
(3). Tete'e Suau'u, Tete'e Corrosion, ma Fauga Fa'auupega
I iunite i fafo e pei o FPSOs ma dredgers, uaea Ethernet e masani ona faʻaalia i le suauu ma faʻasalalauga faʻasalalau. Ina ia fa'aleleia atili le fa'atumauina o le fa'afu, e fa'aogaina mea e fa'alava ai le polyolefin sheath material (SHF2) po'o mea SHF2 MUD e tete'e palapala, e fa'atatau ile NEK 606 tulaga fa'ama'i. Ina ia faʻaleleia atili le malosi faʻainisinia, e mafai ona faʻaofuofu uaea i uʻamea uamea faʻapipiʻi (GSWB) poʻo pipili uaea apa (TCWB), tuʻuina atu le faʻamalosi ma le malosi faʻamalosi, faʻatasi ai ma le talipupuni eletise e puipuia ai le faʻamaoni.
(4). Tete'e UV ma Galuega Fa'amatua
O laina Ethernet o le gataifale e masani ona faʻaalia i le susulu o le la, o le mea lea e tatau ai ona lelei le faʻafefe o UV. E masani lava, polyolefin sheathing with carbon black or UV-resistant additives e faʻaaogaina ma faʻataʻitaʻiina i lalo ole UL1581 poʻo le ASTM G154-16 UV tulaga matutua e faʻamautinoa ai le mautu o le tino ma le faʻalauteleina o le ola tautua i siosiomaga maualuga UV.
I se aotelega, o vaega uma o le gataifale Ethernet mamanu uaea e vavalalata vavalalata i le filifilia ma le faaeteete o mea uaea. O ta'ita'i apamemea sili ona lelei, mea fa'apipi'i HDPE po'o PO, pepa alumini Mylar lipine, fa'amau uaea apamemea, lipine mika, mea fa'apipi'i XLPO, ma mea fa'apipi'i SHF2 fa'atasi e fausia ai se uaea feso'ota'iga e mafai ona tatalia si'osi'omaga o le gataifale. I le avea ai o se kamupani faʻatau oloa, matou te malamalama i le taua o le tulaga lelei o meafaitino i le faʻatinoina o le cable atoa ma o loʻo tuuto atu i le tuʻuina atu o fofo faʻalagolago, saogalemu, ma maualuga faʻatinoga mo le gataifale ma pisinisi i fafo.
