Fiber optic kev twb kev txuas yog ib qho tseem ceeb nyob rau hauv fiber optic kev sib txuas lus systems, txiav txim siab qhov zoo thiab efficiency ntawm optical teeb liab kis tau tus mob nyob rau hauv lub network. Muaj peb hom kev sib txuas ntawm fiber ntau optic: mus tas li fusion splicing, thaum muaj xwm ceev splicing (txias splicing), thiab connectorized (kev ua si) kev sib txuas. Txhua hom muaj nws qhov tshwj xeeb daim ntawv thov scenarios, zoo, thiab drawbacks.
Permanent Fusion Splicing
Qhov zoo:
Tsawg Attenuation: Muab qhov qis tshaj attenuation ntawm txhua txoj kev sib txuas, feem ntau xws li ntawm {{0}}.01 txog 0.03 dB ib splice, kom ntseeg tau tias muaj kev sib kis tau zoo.
Long-term Stability: Tsim ib qho kev sib txuas mus tas li nrog lub cev muaj zog thiab kev ruaj ntseg ntev, haum rau kev sib txuas lus ntev thiab kev siv siab.
Qhov tsis zoo:
Cov Khoom Siv Tau Txais: Yuav tsum tau tshwj xeeb fusion splicers thiab cov neeg ua haujlwm txawj, ua rau cov nqi siab dua.
Kev Tiv Thaiv Kev Xav Tau: Cov ntsiab lus splice yuav tsum muaj kev tiv thaiv tshwj xeeb los tiv thaiv kev puas tsuaj thiab kev cuam tshuam ib puag ncig.
Emergency Splicing (Cold Splicing)
Qhov zoo:
Kev sib txuas ceev: Siv cov txheej txheem kev siv tshuab thiab tshuaj rau kev kho fiber ntau thiab kev sib txuas, tsim rau kev kho thaum muaj xwm ceev.
Kev ntseeg tau: Muab kev sib txuas ruaj khov nyob rau lub sijhawm luv luv, nrog rau kev txo qis ntawm {{0}}.1 txog 0.3 dB ib splice.
Qhov tsis zoo:
Long-term Instability: Kev siv mus sij hawm ntev tuaj yeem ua rau kev sib txuas tsis ruaj khov thiab muaj kev cuam tshuam loj, txwv tsis pub nws tsim nyog rau kev siv mus sij hawm ntev.
Higher Attenuation: Piv rau fusion splicing, txias splicing exhibits ntau dua attenuation.
Connectorized (Kev Ua Haujlwm) Kev Sib Txuas
Qhov zoo:
Flexibility: Siv fiber ntau optic connectors (plugs thiab sockets) kom yooj yim txuas cov chaw lossis cables, muab kev yooj yim thiab yoog raws.
Simplicity: Kev teeb tsa thiab kev saib xyuas yog qhov yooj yim, tsis tas yuav tsum muaj cov cuab yeej nyuaj lossis kev txawj tshwj xeeb.
Daim ntawv thov dav: Zoo tagnrho rau siv hauv kev tsim cov tes hauj lwm, xws li cov chaw zov me nyuam cov ntaub ntawv thiab cov tsev ua haujlwm.
Qhov tsis zoo:
Higher Attenuation: Connectorized kev sib txuas feem ntau pom muaj ntau dua attenuation, nyob ib ncig ntawm 1 dB ib qho kev sib txuas, uas tej zaum yuav cuam tshuam cov teeb liab kis tau zoo.
Connector Quality Dependence: Qhov zoo ntawm cov connectors ncaj qha cuam tshuam rau stability thiab attenuation ntawm qhov kev twb kev txuas.
