Hauv cov xwm txheej zoo li fiber ntau-rau-tsev (FTH), 5G lub tsev sab hauv tsev, thiab ntse lub tsev feem ntau yuav tsum tau ua kom nruj li cov ces kaum, cov cooj txwv nruj, lossis rov ua dua. Tsoos ib-hom fibers (piv txwv li, g.652) raug kev txom nyem los ntawm kev poob qis, ua rau teeb liab kev ua haujlwm lossis tsis ua tiav. G.657 Fiber, nrog nws cov kev tawm tsam khoov-resistant cov khoom, tau tawm los ua kev ua si-hloov pauv. Cov kab lus no dhia mus rau hauv cov yam ntxwv ploj ntawm G.657 fiber ntau, tshawb txog nws cov qauv tsim, kev ua tau zoo, thiab cov ntawv thov tiag tiag.
1. Dabtsi yog khoov poob: Achilles 'pob taws ntawm cov tsoos fiber ntau
Thaum khoov duav, lub teeb taw qhia hauv qhov muag ntawm qhov muag dej ntws los vim muaj ob hom poob, uas muaj ob hom:
Macrobending poob:Tshwm sim los ntawm loj-vojvoog khoov (piv txwv li, coiling nrog tsis txaus vojvoog).
Microbending poob:Tshwm sim los ntawm cov me, tsis xwm yeem (piv txwv li, siab lossis nruj nrhab).
Txwv ntawm ib txwm muaj fiber ntau-hom fiber ntau (G.652):
Qhov tsawg kawg nkaus khoov radius:30 hli (ntev lub sij hawm), 15 hli (luv-lo); Tshaj li no, poob loj.
MacRobending poob (1550nm): txog 1dB / tig ntawm 10mm khoov rend radius, tsis tsim nyog rau cov chaw ib puag ncig.
2. G.657 Fiber ntau cov khoov tsis kam: Cov qauv kev tsim kho
G.657, ib qho kev sib tw ua-tsis tau zoo - hom fiber ntau, minimizes khoov ntawm cov tub ntxhais kawm siab thiab cov cladding. TSEEM CEEB LOJ Muaj xws li:
Refacking Index Profile Kev Txhim Kho
Kev Pab Cuam Tshuam Tsim:Tus ntiv nplhaib tsawg-deptive-index ncig cov tub ntxhais ua raws li "lub teeb ntxiab" kom txo lub teeb liab.
Hom teb txoj kab uas hla (MFD) txuam:Kho cov tub ntxhais cov tsiaj ntawv tshaj tawm txhim kho lub teeb kaw cia rau hauv cov xwm txheej.
3Cov. 4 daim ntawv thov ntawm g.657 fiber ntau
Ftth (fiber ntau-rau-hauv-tsev)
Muaj sia nyob ntse khoov thiab nruj nrhab nyob rau hauv cov xov xwm.
Kev tshawb nrhiav rooj plaub: NTT Nyiv siv G.657.a2 rau 90 degree phab ntsa ces nruab tau nruab.
5g Sab Hauv Tsev Tes Haujlwm
Pab kom tuab cable hauv elevators, ductions, thiab chaw kaw.
Cov Chaw Nruab Nrab Cov Khoom Siv Hluav Taws Xob
Txo cov chaw hauv racks nrog LC / MPO cov twj sib txuas.
Industrial & vehabular
Tsis kam tawm tsam thiab tsoo hauv cov teeb meem, tsheb nqaj hlau, lossis neeg hlau.

G.657 Receeter Receefines yoog tau hauv kev sib txuas lus kho qhov muag, kev daws cov kev sib tw tseem ceeb hauv cov xaim xaim hluav taws xob. Los ntawm cov chaw nyob broadband rau kev lag luam 4. {2}}}}}, nws cov khoom khoov poob rau kev ntseeg tau kev ntseeg tau thiab kev yoog tau. Los ntawm kev xaiv txoj cai G.657 subtype thiab adhering rau intallation kev teeb tsa zoo tshaj plaws, koj tuaj yeem ua pov thawj rau cov twists thiab hloov ntawm qhov tseeb-ntiaj teb kev xa tawm.
