Dab tsi yog Standard Diameter ntawm Fiber Optic Cable?

Cov txheej txheem txheej txheej ntawm ib qho fiber ntau optical feem ntau yog li ntawm 125 txog 140 micrometers (µm), thaum lub core inch feem ntau poob ntawm 3 thiab 100 µm. Cov hauv qab no muab cov lus piav qhia ntxaws txog qhov ntev ntawm optical fibers:

** Optical Fiber Outer Diameter:** Cov kab uas hla ntawm cov fiber ntau optical feem ntau ntsuas ntawm 125 thiab 140 micrometers. Qhov ntau yam no yog tsim los ntawm cov qauv tsim thiab kev tsim khoom tshwj xeeb, ua kom muaj kev ruaj ntseg thiab kev ua haujlwm ntawm fiber ntau thaum lub teeb liab kis tau tus mob.

**Core Diameter:**

** Multimode Fiber:** Txoj kab uas hla ntawm cov tub ntxhais fiber ntau feem ntau yog li ntawm 15 txog 50 micrometers. Qhov loj me no tso cai rau ntau hom fiber ntau xa tawm ntau hom teeb liab kho qhov muag ib txhij, ua rau nws haum rau luv - nrug, siab - bandwidth daim ntawv thov. Nws txoj kab uas hla tseem ceeb yog kwv yees li qhov tuab ntawm tib neeg cov plaub hau.

**Singlemode Fiber:** Cov tub ntxhais txoj kab uas hla yog me me, feem ntau yog li ntawm 8 mus rau 10 micrometers. Singlemode fiber kis tsuas yog ib hom teeb pom kev kho qhov muag xwb, ua rau nws zoo tagnrho rau qhov ntev - nrug, siab - kev sib txuas lus ceev.
**Fiber Structure:** Ntxiv rau cov tub ntxhais, ib qho khoom siv kho qhov muag feem ntau muaj txheej txheej cladding thiab txheej txheej. Lub cladding pab txhawm rau txhawm rau kho qhov muag teeb liab hauv lub hauv paus, thaum lub txheej tiv thaiv cov fiber ntau los ntawm kev puas tsuaj thiab ib puag ncig. Raws li cov neeg siv khoom xav tau, cov txheej txheem ntxiv cov txheej txheem -xws li Kevlar reinforcement los yog xoob-tube buffering- tej zaum yuav raug ntxiv los txhim kho cov neeg kho tshuab lub zog thiab kav ntev ntawm cov khoom siv kho qhov muag.
