Optical faibha fiber yakagadzirwa negirazi kana purasitiki, uye iyo fiber pachayo haina kusimba uye inotsemuka nyore. Uye kuvhara iyo diki fiber mubhachi repurasitiki inobvumira kukotama pasina kutyora. Tambo ine optical fiber yakaputirwa mujasi rekudzivirira ndiyo tambo ye optical. Ko tambo yemaziso inogona kukotamiswa pamadiro here?
Sezvo iyo fiber inonzwa kuneta, kuipeta kunogona kuita kuti chiratidzo chemaziso chidonhe kuburikidza nefiber cladding, uye sezvo bend rinowedzera kukwira, chiratidzo chemaziso chinodonha zvakanyanya. Kupeta kunogonawo kukonzera microcracks iyo inogona kukuvadza zvachose fiber. Kuwedzera kune dambudziko, microflex mapoinzi inonetsa kuwana uye inoda inodhura michina yekuyedza, zvirinani mabhiriji anoda kucheneswa kana kutsiviwa. Kukotama kwefiber kunogona kukonzera fiber attenuation. Huwandu hwekudzikisira nekuda kwekukotama kwefiber hunowedzera sezvo radius ye curvature inodzikira. Iyo attenuation nekuda kwekukotama yakakura pa1550 nm pane pa1310 nm, uye yakatokura pa1625 nm. Nokudaro, kana uchiisa fiber jumpers, kunyanya munzvimbo yakakwirira-density cabling, jumper haifaniri kunge yakakotama kupfuura iyo inogamuchirwa bend radius. Saka ndeipi radius yakakodzera ye curvature?
Iyo fiber bend radius ndiyo kona iyo iyo fiber inogona kubhenda zvakachengeteka chero ipi zvayo nzvimbo. Fiber bending radii dzakasiyana kune ese tambo kana chigamba tambo uye dzinogona kusiyana zvichienderana nerudzi rwetambo kana magadzirirwo ayo. Iyo shoma yekubhenda radius inoenderana nedhayamita uye mhando yetambo yemaziso, kazhinji fomula inoshandiswa: iyo shoma yekubhenda radius = dhayamita rekunze retambo yemaziso x kuwanda kwetambo yemaziso.
Iyo itsva ANSI/TIA/EIA-568B.3 chiyero inotsanangura zvishoma bend radius zviyero uye yakanyanya tensile masimba e50/125 micron uye 62.5/125 micron fiber optic cables. Iyo shoma bend radius inotsamira pane chaiyo fiber optic tambo. Muchiitiko chekusagadzikana, radius yekupeta yetambo yemaziso haifanire kunge isingasviki kagumi dhayamita yekunze (OD) yetambo yemaziso. Pasi pekutakura kwekumanikidza, radius yekukotama yetambo yemaziso ndiyo dhayamita yekunze yetambo yemaziso ka15. Miyero yeindasitiri yematambo echinyakare-modhi yechigamba kazhinji inotsanangudza radius diki yekubhenda yakapetwa kagumi dhayamita rekunze retambo ine jaketi kana 1.5 inches (38 mm), chero chikuru. Iyo inowanzoshandiswa G652 fiber ine zvishoma bend radius ye30mm.
G657, iyo yakashandiswa mumakore achangopfuura, ine diki bend radius, kusanganisira G657A1, G657A2 uye G657B3 Iyo shoma bend radius yeG657A1 ndeye 10mm, G657A2 fiber ndeye 7.5mm, uye fiber G657B3 i5mm. Mhando iyi yefiber yakavakirwa paG652D faibha, iyo inonatsiridza kubhenda attenuation hunhu uye geometric hunhu hwefiber, nekudaro ichivandudza hunhu hwekubatanidza hwefiber, inozivikanwawo sekukotama attenuation insensitive fiber. Inonyanya kushandiswa muFTTx, FTTH, yakakodzera kushandiswa munzvimbo diki dzemukati kana makona.
Ose mafiber breaks uye kuwedzera attenuation anogona kuve nemhedzisiro yakakura pakuvimbika kwenetiweki kwenguva refu, mutengo wekushandisa network, uye kugona kuchengetedza nekukura hwaro hwevatengi. Naizvozvo, isu tinofanirwa kunyatsoziva iyo shoma yekubhenda radius yefiber kuchengetedza tambo kana chigamba tambo iri mumamiriro ekushanda akanaka.
