Qhov ob hom kev khoov khoov hluavtaws fiber ntau ua ke yuav raug qhia hauv qab no.
Ib leeg-hom Khoov Insensitive Fiber Patch Cable
Ib hom-hom khoov ua tsis tau lub fiber ntau thaj cables muaj kev lag luam tau ob peb xyoos. ITU pom zoo G.657 qhia meej ob chav kawm ntawm ib hom-hom khoov ua raws li cov hlua fiber ua ke: G.657 A thiab G.657 B. Txhua pawg (A thiab B) tau muab faib ua ob qeb ncua: G.657.A1, G.657.A2 thiab G.657.B1, G.657.B2. Qhov tsawg kawg nkaus khoov vojvoog ntawm G.657.A1 fibers yog 10 hli, G.657.A2 thiab G.657.B1 fibers yog 7.5 hli thiab G.657.B2 fibers yog 5 hli. G.657.A1 thiab G.657.A2 cov fibers tau raws li ITU-T G.652.D fiber ntau.
Piv nrog tsawg kawg khoov vojvoog ntawm tus qauv ib hom G.652 fibers, uas feem ntau 30 hli, G.657 ib-hom khoov insensitive fiber thaj thaj muaj ntau yam ntxiv hloov pauv, uas yog li tuaj yeem ntseeg siab tau ntsia nrog ntau hom kev teeb tsa. thiab nyob rau hauv cov ntaub ntawv thov nce siab hauv cov hnub no' s chaw khaws ntaub ntawv.
Multimode Khoov Insensitive Fiber Patch Cable
Multimode khoov insensitive fiber patch thaj uas muaj qhov tsawg kawg khoov vojvoog ntawm 7.5 hli piv heev haum rau 30 hli khoov vojvoog kab ke teev tseg. Yuav kom ua tiav qhov no, qhov ntsuas qhov tseeb&tso tawm; trench" yog ntxiv rau qhov chaw tawm sab nraud ntawm cheeb tsam fiber ntau. Lub koob npe no khaws cia feem ntau ntawm lub teeb uas yuav tau dim qhov tseem ceeb ntawm cov kab ke multimode.
Qhov xav tau rau lub cev ntom nti ntom nti tau tsim kho raws li feem ntau ntawm FTTH (fiber rau tsev) ua lag luam. Txawm li cas los xij, cov txiaj ntsig rau kev ua lag luam premise tau pom sai sai, tshwj xeeb tshaj yog nyob rau cov chaw zov me nyuam cov ntaub ntawv uas muaj ntau thiab ntau dua cov fiber ntau tau nruab rau hauv cov chaw me. Qhov kev cia siab yog tias qhov tshiab no muaj peev xwm ua kom muaj kev xa cov multimode fibers hauv ntau dua qhov tau siv ntau yam.

Khoov ua kom lub ntsej muag tsis muaj fiber ntau cov xaim hluav taws xob tau ua nrog lub pob hluav taws xob uas tuaj yeem pab cov hlua hluav taws xob cable kom txo qhov muag ploj thaum lub cable tau khoov. Lawv muab cov khoom zoo tib yam, kev siv tshuab thiab ua kom pom kev zoo dua qub raws li cov qauv siv fiber ntau txuas nrog lub peev xwm ntxiv ntawm kev tswj qhov kev ua tau zoo thaum khoov los yog yoog. Khoov ua raws li cov hlua fiber ntau cov kab muaj nyob rau multimode (OM2, OM3 thiab OM4) thiab ib hom (OS2) tes hauj lwm. Txawm hais tias xaiv ib hom khoov khoov insensitive fiber patch thaj los yog multimode khoov insensitive fiber patch thaj, koj tuaj yeem txiav txim siab raws li koj cov ntawv thov. Pab pawg HTF yuav pab koj tsim cov lag luam tsim kom haum cov kab ua haujlwm fiber ntau ua kom tsis muaj zog.
