Kaofela rea tseba hore thapo ea Fiber-optic e boetse e rehile optical-fiber cable. Ke mohala oa marang-rang o nang le likhoele tsa likhoele tsa khalase ka har'a casing e sirelelitsoeng. Li etselitsoe bakeng sa marang-rang a malelele, a sebetsang hantle haholo, le likhokahano tsa mehala.
Ho ipapisitsoe le Fiber Cable Mode, re nahana hore likhoele tsa fiber optic li kenyelletsa mefuta e 'meli: mohala oa fiber o le mong (SMF) le mohala oa fiber oa multimode (MMF).
Single Mode Fiber Optic Cable
Ka bophara ba mantlha ba 8-10 µm, fiber e le 'ngoe ea optic e lumella mokhoa o le mong feela oa leseli ho feta, ka hona, e ka tsamaisa matšoao ka lebelo le phahameng haholo ka ho fokotseha ho tlase, e leng se etsang hore e tšoanelehe bakeng sa phetisetso ea sebaka se selelele. Mefuta e tloaelehileng ea lithapo tsa optical mode ke OS1 le OS2 fiber cable. Tafole e latelang e bontša phapang lipakeng tsa thapo ea OS1 le OS2 fiber optic.
Multimode Fiber Optic Cable
Ka bophara bo boholo ba 50 µm le 62.5 µm, thapo ea multimode fiber patch e ka tsamaisa mefuta e fetang e le 'ngoe ea khanya. Ha ho bapisoa le mohala o le mong oa fiber optic, thapo ea multimode optical e ka ts'ehetsa phetisetso ea sebaka se khuts'oane. Lithapo tsa optical tsa Multimode li kenyelletsa OM1, OM2, OM3, OM4, OM5. Ho na le litlhaloso le ho se tšoane ha bona ka tlase.
Phapang ea tekheniki lipakeng tsa cable ea mode e le 'ngoe le ea mefuta e mengata:
Ho na le tse ngata tsa tsona. Empa mona ke tsa bohlokoa ka ho fetisisa:
Bophara ba li-cores tsa bona.
Mohloli oa leseli le modulation o sebelisoang ke li-transmitter tsa optical.
