Kev faib tawm ntawm cov qauv tseem ceeb ntawm optical cables

Ntau hom kev kho qhov muag cables tau tsim raws li cov kev xav tau ntawm kev siv thiab ib puag ncig, nrog rau ntau hom qauv uas tuaj yeem muab faib ua pawg hauv qab no:
1. Tight qauv kho qhov muag cable: nyob rau hauv cov qauv no, lub npog qhov muag fiber yog twisted rau hauv ib tug cable nrog ib tug tej yam suab thiab tightly embedded rau hauv yas. Cov fibers optical siv nyob rau hauv twisted optical cables muaj xws li kaw ntom nti optical fibers thiab xoob qhwv optical fibers. Nyob rau hauv xoob qhwv optical fibers, vim qhov ntev ntawm cov optical fiber ntau hauv lub tes tsho yas, thaum lub optical cable yog stretched, lub optical fiber yuav muaj ib tug npaum li cas ntawm chav tsev rau kev txav mus los hauv lub tes tsho, uas ua rau lub strain quab yuam. optical fiber ntau yog tsawg tshaj li qhov strain ntawm optical cable.
2. Loose qauv kho qhov muag cable: nyob rau hauv cov qauv no, lub optical fiber nyob rau hauv ib tug loj qhov chaw thiab muaj ib tug txheeb ze chav rau kev txav. Cov qauv kho qhov muag no tsis yog tsuas yog muaj lub zog tensile zoo, tab sis kuj muaj kev cuam tshuam zoo heev, thiab me ntsis khoov attenuation los ntawm cabling me me. Nws qhov tsis zoo yog tias kev siv tshuab ua haujlwm yog qhov nyuaj.
3. Ribbon qauv kho qhov muag cable: Qhov no yog ib qho tshwj xeeb kho qhov muag cable qauv. Nws yog los npaj ntau cov fibers kho qhov muag rau hauv kab los tsim ib lub ribbon optical cable unit, thiab tom qab ntawd npaj thiab twist ob peb ribbon units nyob rau hauv ib txoj kev los tsim ib tug cable. Qhov no optical cable yog tus cwj pwm los ntawm qhov chaw ua haujlwm siab, kev ua haujlwm yooj yim thiab kev txheeb xyuas ntawm cov khoom siv kho qhov muag, thiab tuaj yeem txuas ntau yam khoom siv kho qhov muag hauv ib lub sijhawm. Qhov tsis zoo yog tias cov txheej txheem tsim khoom yog qhov nyuaj, thiab cov microbending attenuation tshwm sim los ntawm kev ua thiab cov yam ntxwv ntawm qhov kub thiab txias ntawm qhov kho qhov muag cable yog qhov nyuaj rau tswj.
