Dual-core Optical Cable Txhawb Txoj Kev Loj Hlob Thoob Ntiaj Teb Yas Hloov Kho Cov Khoom Kho Kom Zoo
Lub koom haum German ntawm Engineers thiab Pawg Tshawb Fawb ntawm Lub Tsev Kawm Ntawv Hluav Taws Xob tau qhia tshwj xeeb hauv kev ntsuas kev ntsuas ntawm tus lej ntawm lub ntsej muag, kev saib xyuas, kis thiab cov khoom ntawm cov yas kho qhov muag, nrog rau ib puag ncig thiab lub neej. Kev tsim cov yas optical fiber kev tshuaj xyuas txoj kev thiab cov qauv yuav yeej txhawb txoj kev loj hlob ntawm thoob ntiaj teb yas kho qhov muag fiber ntau kev lag luam thiab tshem tawm kev nkag siab yuam kev hauv kev ua lag luam.
Nyiv txuas yog qhov tseem ceeb rau daim ntawv thov ntawm cov yas kho qhov muag. Thaum ntxov li ob peb xyoos dhau los, 45 cov tuam txhab tsim kev sib txuas lus kho qhov muag thiab cov khoom siv ntau yam, suav nrog NEC, Fujitsu, thiab Sumitomo Hluav Taws Xob Kev Lag Luam, tau tshaj tawm tias lawv yuav sib koom ua tiav txoj kev vam meej ntawm cov yas optical fiber hauv Nyiv. Tswv yim. Tus nqi qis ntawm cov yas fiber ntau kho tau pom tias yog qhov tseem ceeb thev naus laus zis los qhia ntau hom rau hauv tsev, thiab tom qab ntawd qee cov tuam txhab tsim tawm los tsim cov kab ntau lawm.
Xyoo 1986, Nyiv F Fujitsu tsim SI hom kub-resistant POF nrog PC ua cov khoom siv tseem ceeb. Qhov kub kub tiv thaiv kub tuaj yeem ncav cuag 135 degrees Celsius, thiab qhov chaw xis taws tuaj yeem ncav cuag 450dB / km;
Xyoo 1990, Assistant Professor Koike ntawm Keio University hauv Nyij Pooj tau tsim tiav qhov ntsuas qhov tsis zoo ntawm qhov muag yas fiber ntau, cov khoom siv tseem ceeb yog fluorine-muaj PMMA, cov cladding yog fluorinated yas, thiab interface gel tshuab tau siv. Cov yas fiber ntau muaj qhov ua tau pov tseg hauv qab 60db / km, lub teeb pom kev ntawm 650-1300nm, 100m bandwidth ntawm 3GHz, thiab cov kab sib kis ntawm 10Gb / s, uas dhau ntawm GI-hom quartz optical fiber, thiab yog dav suav tias kho qhov muag sib txuas lus nruab nrab tshiab rau cov xov paj fiber ntau rau hauv tsev hauv qhov high-speed multimedia era;
Nyob rau xyoo 1996, tib neeg tau tawm tswv yim los tsim qhov kev siv nyiaj tsawg kawg ntawm cov neeg siv network ATM lub cev txheej txheem raws cov khoom siv yas kho qhov muag; nyob rau hauv 1997, Nyiv' s NEC Corporation tau ntsuas 155Mbit / s ATM thiab LAN ntsuas.
Ntawm lub rooj sab laj OFC xyoo 2000, Nyiv' s ASAHI GLASS qhia tias cov khoom sib txuam ntawm fluorinated gradient yas kho qhov muag fiber ntau (GI-POF) yog 70dB / km ntawm 850nm thiab 33dB / km ntawm 1300nm, nrog bandwidth ntawm 100mhz / km. Nrog rau cov fiber ntau no, 50m, 2.5Gbit / s siab ceev kis thiab 70 ° C lub sij hawm ntev kev laus kev laus tau ua tiav zoo. Qhov kev sim xaus yog tias fluorinated gradient yas optical fiber ntau tuaj yeem ua tau raws li qhov yuav tsum tau ntawm kev sib txuas lus luv.
