Mohala oa marang-rang, o tsejoang hape e le thapo ea data kapa thapo ea marang-rang, e sebetsa e le mokhoa oa ho fetisa tlhahisoleseling ho tloha sesebelisoa se seng sa marang-rang (joalo ka komporo) ho ea ho se seng.Ke karolo ea bohlokoa le ea mantlha ea sistimi efe kapa efe ea marang-rang, e nolofalletsang phetiso ea data le puisano lipakeng tsa lisebelisoa.
1.Mefuta ea Lithapo tsa Netweke:
Lithapo Tse Pelaneng Tse Sothehileng (UTP/STP):
Mofuta o sebelisoang haholo oa thapo ea marang-rang.
E na le lipara tse 'ne tsa mehala ea koporo e sothehileng hammoho ho fokotsa tšitiso ea motlakase.
Unshielded Twisted Pair (UTP) ke mofuta o atileng haholo, ha Shielded Twisted Pair (STP) e fana ka tšireletso e eketsehileng khahlano le tšitiso.
E loketse phetisetso ea sebaka se khuts'oane, e sebelisoang hangata ho Local Area Networks (LANs).
2.Coaxial Cable:
E entsoe ka mokokotlo oa koporo kapa oa aluminium o pota-potiloeng ke lera le sireletsang le lisebelisoa tse sirelelitsoeng.
E khona ho tsamaisa matšoao a nang le maqhubu a phahameng, a sebelisoang haholo-holo bakeng sa matšoao a thelevishene a analog le likhokahano tse ling tsa marang-rang.
Ha e tloaelehe haholo marang-rang a sejoale-joale ka lebaka la ho phahama ha mats'oao a dijithale le likhoele tsa fiber optic.
3.Fiber Optic Cable:
E entsoe ka likhoele tsa khalase kapa tsa polasetiki tse fetisang data ho sebelisa khanya ea leseli.
E fana ka bandwidth e phahameng, phetisetso ea sebaka se selelele ka tahlehelo e nyane ea matšoao.
E loketse bakeng sa likhokahano tsa marang-rang tsa mokokotlo le nako e telele.
Likarolo le Melemo ea Lithapo tsa Marang-rang:
Flexibility: Lithapo tsa marang-rang li ka tsamaisoa habonolo le ho kenngoa libakeng tse fapaneng.
Tšebeliso ea Litšenyehelo: Lithapo tse peli tse sothehileng, haholo-holo UTP, li batla li le theko e tlaase ebile li fumaneha hohle.
Scalability: Marang-rang a ka atolosoa habonolo ka ho eketsa likhoele le lisebelisoa tse ling.
Durability: Lithapo tsa marang-rang li etselitsoe ho mamella ho senyeha, ho netefatsa likhokahano tse tšepahalang.
Maemo le Litlhaloso:
Lithapo tsa marang-rang li lumellana le maemo a fapaneng a indasteri, joalo ka EIA/TIA 568A le 568B, tse hlakisang tlhophiso ea likhoele le pinout ea likhoele.
Likarolo tse fapaneng tsa lithapo (Cat 5, Cat 5e, Cat 6, joalo-joalo) li fana ka maemo a fapaneng a ts'ebetso, ho kenyelletsa bandwidth, frequency, le lebelo la phetisetso.
Ka kakaretso, likhoele tsa marang-rang li phetha karolo ea bohlokoa ho hokahanya lisebelisoa le ho nolofalletsa puisano ea data ka har'a marang-rang.Khetho ea mofuta oa cable e itšetlehile ka litlhoko tse khethehileng tsa marang-rang, ho kenyelletsa le bandwidth, sebaka sa phetisetso, le ho nahanela litšenyehelo.
