Cov pigtail fiber ntau yog hais txog qhov sib txuas zoo ib yam li ib nrab jumper siv los txuas cov fiber ntau optical thiab optical fiber txuas.Nws muaj xws li jumper connector thiab ib seem ntawm optical fiber.Los yog txuas cov khoom siv sib kis thiab ODF racks, thiab lwm yam.
Tsuas yog ib qho kawg ntawm optical fiber pigtail yog ib qho kev sib txuas.Hom connector yog LC / UPC, SC / UPC, FC / UPC, ST / UPC, LC / APC, SC / APC, FC / APC.Ob qhov kawg ntawm lub jumper yog txav tau txuas.Muaj ntau ntau hom interfaces, thiab sib txawv interfaces yuav tsum tau sib txawv couplers.Lub jumper tau muab faib ua ob thiab tuaj yeem siv los ua pigtail.
Cov tub ntxhais txoj kab uas hla ntawm multimode fiber ntau yog 50-62.5μm, sab nraud txoj kab uas hla ntawm lub cladding yog 125μm, cov tub ntxhais txoj kab uas hla ntawm ib hom fiber ntau yog 8.3μm, thiab sab nraud txoj kab uas hla ntawm cladding yog 125μm.Kev ua haujlwm wavelength ntawm optical fiber muaj luv wavelength 0.85μm, ntev wavelength 1.31μm thiab 1.55μm.Fiber poob feem ntau txo nrog qhov ntev ntawm lub wavelength.Qhov poob ntawm 0.85μm yog 2.5dB / km, poob ntawm 1.31μm yog 0.35dB / km, thiab poob ntawm 1.55μm yog 0.20dB / km.Qhov no yog qhov poob qis tshaj ntawm cov fiber ntau, nrog lub wavelength ntawm 1.65 Qhov poob saum toj no μm nyhav nce.Vim yog qhov nqus ntawm OHˉ, muaj qhov poob siab hauv qhov ntau ntawm 0.90 ~ 1.30μm thiab 1.34 ~ 1.52μm, thiab ob qhov no tsis siv tag nrho.Txij li thaum xyoo 1980s, ib hom fibers tau siv ntau zaus, thiab qhov ntev-yoj 1.31μm tau siv ua ntej.
Multimode fiber ntau
Fiber ntau hom:Lub hauv paus iav tseem ceeb yog tuab (50 lossis 62.5μm), uas tuaj yeem kis tau ntau hom teeb.Txawm li cas los xij, qhov sib txawv ntawm hom dispersion yog qhov loj, uas txwv qhov zaus ntawm kev sib kis ntawm cov teeb liab digital, thiab nws yuav hnyav dua nrog qhov nce ntawm qhov deb.Piv txwv li: 600MB / KM optical fiber tsuas muaj 300MB bandwidth ntawm 2KM.Yog li ntawd, qhov kev ncua deb ntawm multimode fiber yog luv luv, feem ntau tsuas yog ob peb kilometers.
Tib hom Fiber
Ib hom Fiber:Lub hauv paus iav core yog nyias nyias (cov tub ntxhais txoj kab uas hla feem ntau yog 9 lossis 10 μm) thiab tuaj yeem kis tau ib hom teeb pom kev zoo xwb.Yog li ntawd, nws inter-hom dispersion yog heev me me, uas yog haum rau kev sib txuas lus nyob deb, tab sis muaj cov khoom dispersion thiab waveguide dispersion.Nyob rau hauv txoj kev no, ib hom fibers muaj cov kev xav tau siab dua rau qhov dav dav thiab kev ruaj ntseg ntawm lub teeb, uas yog, qhov dav spectral yuav tsum nqaim thiab ruaj khov.Zoo dua.Tom qab ntawd, nws tau pom tias nyob rau ntawm lub wavelength ntawm 1.31μm, cov khoom dispersion thiab waveguide dispersion ntawm ib hom fiber ntau yog qhov zoo thiab qhov tsis zoo, thiab qhov loj me yog tib yam.Qhov no txhais tau hais tias ntawm lub wavelength ntawm 1.31μm, tag nrho dispersion ntawm ib hom fiber ntau yog xoom.Los ntawm qhov pom ntawm cov yam ntxwv poob ntawm cov khoom siv kho qhov muag, 1.31μm tsuas yog qhov poob qis ntawm qhov muag fiber ntau.Nyob rau hauv txoj kev no, thaj tsam 1.31μm wavelength tau dhau los ua lub qhov rais ua haujlwm zoo tshaj plaws rau kev sib txuas lus fiber ntau, thiab nws kuj yog lub luag haujlwm tseem ceeb ntawm kev siv cov kev sib txuas lus fiber ntau tam sim no.Cov tsis tseem ceeb ntawm 1.31μm cov pa ib hom fiber ntau yog txiav txim los ntawm International Telecommunication Union ITU-T hauv G652 pom zoo, yog li cov fiber ntau no tseem hu ua G652 fiber.
Ib hom fiber ntau, cov tub ntxhais txoj kab uas hla yog me me (8-10μm), cov teeb liab kho qhov muag tsuas yog kis tau ntawm ib qho kev daws teeb meem nrog lub axis fiber ntau, thiab tsuas yog kis tau rau hauv ib hom nkaus xwb, uas tsis txhob hloov pauv hloov pauv thiab ua rau chav sib kis. bandwidth dav.Lub peev xwm kis tau tus mob loj, lub teeb liab optical poob yog me me, thiab qhov tawg yog me me, uas yog tsim rau kev muaj peev xwm loj thiab kev sib txuas lus ntev.
Multi-mode fiber ntau, lub teeb liab kho qhov muag thiab cov fiber ntau axis kis tau los ntawm ntau qhov kev daws teeb meem, thiab ntau lub teeb kis tau los ntawm ntau hom tib lub sijhawm.Txoj kab uas hla yog 50-200μm, uas yog qis dua rau kev sib kis ntawm ib hom fiber ntau.Nws tuaj yeem muab faib ua multimode abrupt fiber ntau thiab multimode graded fiber ntau.Cov qub muaj cov tub ntxhais loj dua, ntau hom kev sib kis, nqaim bandwidth, thiab muaj peev xwm kis tau me me.
RAISEFIBER tshwj xeeb hauv kev tsim cov hlua kho qhov muag thiab cov pigtails, thiab muab cov khoom siv fiber ntau rau cov neeg siv khoom nrog kev sib txuas.
