Lits'ebetsong tsa lebelo le phahameng, khetho ea lisebelisoa tsa mohala le lithapo li bapala karolo ea bohlokoa ho netefatsa ts'ebetso e nepahetseng le ts'epo. Tlhokahalo ea litekanyetso tse potlakileng tsa phetisetso ea data le bandwidth e ntseng e eketseha e hloka ho shebisisa lintlha tse fapaneng ha u khetha lisebelisoa tse loketseng. Sengoliloeng sena se totobatsa lintlha tsa bohlokoa tse lokelang ho nahanoa ha u khetha terata e lebelo le lisebelisoa tsa cable, ho fana ka leseli la hore na lisebelisoa tse nepahetseng li ka matlafatsa botšepehi ba matšoao joang, ho fokotsa tahlehelo ea matšoao, le ho netefatsa phetiso e nepahetseng ea data.
Pontšo ea Botšepehi le Tlhokomelo
Ho boloka botsitso ba matšoao ho bohlokoa lits'ebetsong tsa lebelo le holimo. Thepa e khethiloeng le lisebelisoa tsa cable li lokela ho bonts'a ho fokotseha ha matšoao a tlase, ho fokotsa tahlehelo ea matla a pontšo nakong ea phetisetso. Lisebelisoa tse nang le dielectric tse fokolang kamehla le tahlehelo ea tangent, tse kang high-density polyethylene (HDPE) kapa polytetrafluoroethylene (PTFE), li thusa ho boloka boleng ba matšoao, ho fokotsa ho khopama, le ho netefatsa phetiso e nepahetseng ea data ho feta libaka tse telele.
Taolo ea Impedans
Taolo e nepahetseng ea impedance e bohlokoa mekhoeng ea puisano e potlakileng. Lisebelisoa tsa terata le lithapo li lokela ho ba le thepa ea motlakase e ts'oanang ho boloka ts'ebetso e ts'oanang ea ts'ebetso. Sena se netefatsa phatlalatso e nepahetseng ea mats'oao, se fokotsa lipontšo, 'me se fokotsa kotsi ea liphoso tsa data kapa ho senyeha ha matšoao. Ho khetha lisebelisoa tse nang le mamello e thata le litšobotsi tse tsitsitseng tsa motlakase, joalo ka polyolefin e nang le foamed kapa fluorinated ethylene propylene (FEP), e thusa ho fihlela taolo e nepahetseng ea impedance.
Crosstalk le EMI Mitigation
Lithapo tse lebelo le thapo li kotsing ea ho kena lipakeng tsa crosstalk le electromagnetic interference (EMI). Khetho e nepahetseng ea thepa e ka thusa ho fokotsa mathata ana. Lisebelisoa tse sireletsang, tse kang foil ea aluminium kapa lithebe tsa koporo tse lohiloeng, li fana ka tšireletso e sebetsang khahlanong le EMI ea kantle. Ho feta moo, lisebelisoa tse nang le crosstalk e tlase, joalo ka litlhophiso tse sothehileng kapa lisebelisoa tse nang le lijeometri tse ntlafalitsoeng, li thusa ho fokotsa khokahano e sa batleheng ea mats'oao le ho ntlafatsa ts'ebetso ea mats'oao ka kakaretso.
Mehopolo ea Tikoloho
Maemo a ts'ebetso le maemo a tikoloho a tlameha ho tsotelloa ha ho khethoa terata e lebelo le lisebelisoa tsa cable. Phapang ea mocheso, mongobo, lik'hemik'hale le ho pepeseha ha UV ho ka ama ts'ebetso ea thepa le bophelo bo bolelele. Lisebelisoa tse nang le botsitso bo botle ba mocheso, ho hanyetsa mongobo, ho hanyetsa lik'hemik'hale, le ho hanyetsa UV, joalo ka polyethylene (XLPE) kapa polyvinyl chloride (PVC), hangata li khethoa ho netefatsa ts'ebetso e tšepahalang tlas'a maemo a fapaneng a tikoloho.
Ho khetha terata e lebelo le holimo le lisebelisoa tsa cable ho bohlokoa bakeng sa ho fihlela ts'ebetso e nepahetseng, botšepehi ba matšoao le ts'epahalo. Menahano e joalo ka phokotso ea lets'oao, taolo ea impedance, phokotso ea crosstalk le EMI, le lintlha tsa tikoloho ke tsa bohlokoa ha ho etsoa khetho ea lintho tse bonahalang. Ka ho lekola likarolo tsena ka hloko le ho khetha thepa e nang le lisebelisoa tse loketseng tsa motlakase, tsa mochini le tsa tikoloho, bahlahisi ba ka fihlela litlhoko tsa lits'ebetso tsa lebelo le holimo le ho netefatsa phetiso ea data e sebetsang hantle le e tšepahalang.
