Optical fiber ishinda yakagadzirwa negirazi kana purasitiki, uye fiber yacho pachayo inopwanyika nyore nyore uye inotyoka nyore nyore. Kufukidza fiber diki mupurasitiki kunoita kuti ikwanise kukotama isina kutyoka. Tambo ine optical fiber yakaputirwa mumudziyo wekudzivirira inonzi optical cable. Tambo ye optical inogona kukotama painoda here?
Sezvo fiber ichinzwa kusvuta, kuikotamisa kunogona kukonzera kuti chiratidzo che optical chibude nepa fiber cladding, uye sezvo kukotama kuchiwedzera kuoneka, chiratidzo che optical chichatowedzera kudonha. Kukotamisa kunogonawo kukonzera ma microcracks anogona kukuvadza fiber zvachose. Kunze kwedambudziko pacharo, ma microbending points akaoma kuwana uye anoda michina yekuyedza inodhura; zvirinani, ma jumpers anofanira kucheneswa kana kutsiviwa. Kukotamisa fiber kunogona kukonzera kuderera kwe fiber. Huwandu hwekuderera nekuda kwekukotamisa fiber hunowedzera sezvo radius yekukotamisa inoderera. Kuderera nekuda kwekukotamisa kwakakura pa1550 nm pane pa1310 nm, uye kwakatokura pa1625 nm. Saka, pakuisa ma fiber jumpers, kunyanya munzvimbo ine ma cable akawanda, jumper haifanirwe kukotama kupfuura radius yayo inokotama. Saka, ndeipi radius yakakodzera yekukotamisa?
Radiyo yekukombama yefaibha ndiyo kona iyo faibha inogona kukotama zvakachengeteka chero kupi zvako. Radiyo yekukombama yefaibha inosiyana patambo dzese netambo dzechigamba uye inogona kusiyana zvichienderana nerudzi rwetambo uye maitiro ekugadzira. Radiyo yekukombama shoma inoenderana nedhayamita nerudzi rwetambo ye optical; fomura inowanzo shandiswa ndeiyi: radiyo yekukombama shoma = dhayamita yekunze yetambo ye optical x yakawanda yedhayamita ye optical cable.
Muyero mutsva weANSI/TIA/EIA-568B.3 unotsanangura mwero wekukombama kwedhiyabhoritari shoma uye mwero wesimba rekukombama kwedhiyabhoritari ye50/125 micron uye 62.5/125 micron. Mwero wekukombama kwedhiyabhoritari shoma unoenderana netambo chaiyo yefiber optic. Pasina kumanikidzwa, mwero wekukombama wedhiyabhoritari yefiber optic haufanirwe kunge uri pasi pegumi redhayabhoritari rekunze (OD) redhiyabhoritari rekunze. Mumutoro wekukombama, mwero wekukombama wedhiyabhoritari unopetwa ka15 kupfuura dhayabhoritari rekunze redhiyabhoritari refiber optic. Mwero weindasitiri yetambo dzechinyakare dze single-mode patch unowanzo tsanangura mwero wekukombama wedhiyabhoritari shoma yedhiyabhoritari rekunze redhiyabhoritari kana 1.5 inches (38 mm), chero ipi zvayo yakakura. Fiber yeG652 inowanzoshandiswa ine mwero wekukombama wedhiyabhoritari we30 mm.
G657, iyo yave kushandiswa mumakore achangopfuura, ine nzvimbo diki yekukombama, kusanganisira G657A1, G657A2, uye G657B3. Nzvimbo diki yekukombama yeG657A1 i10 mm, yeG657A2 i7.5 mm, uye yeG657B3 i5 mm. Rudzi urwu rwefiber rwakavakirwa paG652D fiber, iyo inovandudza hunhu hwekukombama uye hunhu hwe geometric yefiber, nokudaro ichivandudza hunhu hwayo hwekubatana. Inozivikanwawo sefiber isinganzwe kukotama kwekotama. Inonyanya kushandiswa muFTTx neFTTH, yakakodzera kushandiswa munzvimbo diki dzemukati kana makona.
Kuputsika kwemafiber uye kuwedzera kwekudzikira kwesimba remagetsi kunogona kukanganisa zvakanyanya kuvimbika kwenetwork kwenguva refu, mari yekushandisa network, uye kugona kuchengetedza nekukura kwevatengi. Saka, tinofanira kunzwisisa zvakajeka huwandu hushoma hwefiber bend radius kuti tambo yetambo kana chigamba chirambe chiri mumamiriro akanaka ekushanda.
