• Txo cov teeb liab poob: Khoov-insensitive fiber ntau txo cov teeb liab poob thiab degradation txawm tias thaum raug khoov nruj los yog cov neeg kho tshuab kev ntxhov siab, kom ntseeg tau cov ntaub ntawv xa mus.
• Flexibility thiab txhim kho kev ntseeg tau: Khoov-insensitive fiber ntau hloov tau yooj yim thiab tiv taus macro- thiab micro-bending dua li hom fiber ntau. Qhov no ua rau nws ntseeg tau ntau dua hauv kev teeb tsa qhov twg khoov lossis kev ntxhov siab tsis tuaj yeem zam.
• Yooj yim ntawm installation: Kev txhim kho khoov siab ntev ntawm hom fiber ntau no yooj yim rau kev teeb tsa, tso cai rau kev hloov pauv ntau dua hauv kev xa thiab xa mus. Nws txo qhov kev xav tau ntau dhau ntawm kev khoov-voj vojvoog thiab txo qhov kev pheej hmoo ntawm fiber ntau puas thaum lub sijhawm teeb tsa.

 

Kev Siv Tej Laus

 

Khoov-insensitive fiber pom cov ntawv thov hauv ntau yam xwm txheej, suav nrog:

 

• FTTx Deployments: Khoov-insensitive fiber ntau yog siv nyob rau hauv fiber-to-the-home (FTTH) thiab fiber-to-the-premises (FTTP) deployments, qhov uas nws muaj kev txhim kho kev ua tau zoo nyob rau hauv nruj thiab khoov ib puag ncig.
• Data Centers: Khoov-insensitive fiber ntau yog qhov muaj txiaj ntsig zoo hauv cov chaw khaws ntaub ntawv uas qhov chaw ua kom zoo dua qub thiab kev tswj hwm cable zoo yog qhov tseem ceeb. Nws tso cai rau kom yooj yim dua thiab txhim khu kev qha kev sib txuas hauv qhov chaw kaw.
• Installation sab hauv: Hom fiber ntau no tsim nyog rau kev teeb tsa sab hauv tsev, xws li cov tsev ua haujlwm lossis thaj chaw nyob, qhov chaw muaj kev txwv lossis kev khoov nruj yuav raug ntsib.

 

Khoov-insensitive fiber muab ib qho kev txhim khu kev qha thiab hloov tau yooj yim rau cov ntawv thov qhov twg cov teeb liab poob vim kev khoov los yog cov neeg kho tshuab kev ntxhov siab yog ib qho kev txhawj xeeb. Nws txhim kho khoov kam rau ua thiab txo cov teeb liab degradation ua rau nws zoo haum rau ntau yam teeb meem kev teeb tsa, ua kom ntseeg tau cov ntaub ntawv xa mus.

 

Thaum xaiv qhov tsim nyog fiber ntau optic cable, yam xws li qhov yuav tsum tau muaj kev sib kis deb, bandwidth, tus nqi, ib puag ncig kev teeb tsa, thiab cov ntawv thov tshwj xeeb yuav tsum tau txiav txim siab. Nws yog ib qho tseem ceeb kom sab laj nrog cov kws tshaj lij lossis cov tuam txhab tsim khoom kom ntseeg tau tias cov kab hluav taws xob xaiv tau ua raws li lub hom phiaj thiab cov hom phiaj kev ua haujlwm.

  

Hauv cov ntsiab lus, ntau hom fiber ntau optic cables sib txawv hauv lawv txoj kab uas hla, cov yam ntxwv sib kis, thiab tsim nyog rau cov ntawv thov tshwj xeeb. Kev nkag siab txog qhov sib txawv no tso cai rau kev paub txog kev txiav txim siab thaum xaiv qhov zoo tshaj plaws fiber optic cable rau ib qho xwm txheej.

Hauv kev xaus, cov khoom ntawm fiber ntau optic cables ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev sib kis ntawm cov ntaub ntawv ntawm kev kub ceev thiab dhau mus ntev. Cov hlua fiber ntau, cladding, txheej, cov tswv cuab lub zog, sheath lossis lub tsho, thiab cov khoom sib txuas ua haujlwm sib raug zoo kom ntseeg tau tias cov ntaub ntawv xa mus tau zoo thiab muaj txiaj ntsig. Peb tau pom tias cov ntaub ntawv siv nyob rau hauv txhua yam, xws li iav los yog yas rau cov tub ntxhais, cov txheej txheem tiv thaiv, thiab cov tswv cuab muaj zog, pab txhawb kev ua haujlwm thiab ua haujlwm ntev ntawm fiber ntau optic cables.

 

Tsis tas li ntawd, peb tau tshawb xyuas ntau hom fiber ntau optic cables, suav nrog ib hom fiber ntau, multimode fiber ntau, thiab yas optical fiber ntau, txhua tus nrog nws cov yam ntxwv tshwj xeeb thiab kev siv. Peb kuj tau hais txog cov lus nug ntau txog cov khoom siv fiber ntau optic, xws li cov ntaub ntawv siv thiab kev sib txawv ntawm cov tuam txhab sib txawv.

 

Kev nkag siab txog cov khoom ntawm fiber ntau optic cables yog qhov tseem ceeb rau kev xaiv cov kab tsim nyog tshaj plaws rau cov kev siv tshwj xeeb thiab ua kom pom kev ua haujlwm zoo. Raws li kev siv thev naus laus zis txuas ntxiv mus, fiber ntau optic cables thiab lawv cov khoom yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev tsav peb lub ntiaj teb kev sib txuas mus rau pem hauv ntej. Los ntawm kev paub txog cov khoom no, peb tuaj yeem siv lub zog ntawm fiber ntau optic cables thiab tuav cov txiaj ntsig ntawm kev ceev ceev, txhim khu kev qha, thiab cov ntaub ntawv xa mus tau zoo hauv ntau yam kev lag luam thiab lub neej txhua hnub.
