Khoov Insensitive G.657.A2 Optical Fiber
Khoom Description
Khoov Insensitive Ib hom Optical Fiber (G.657.A2)
Qauv:G.657.A2
• Txheem:Ua raws li lossis tshaj qhov kev qhia tshwj xeeb hauv ITU-T G.657.A1/A2/B2.
• Feature:Yam tsawg kawg nkaus khoov vojvoog 7.5 hli, superior tiv thaiv dabtsi yog khoov khoom.Fully tshaj G.652 ib hom fiber ntau.Full band (1260-1626}nm) kis.Low PMD rau siab bit-rate thiab ntev kis tau tus mob.Tsis tshua muaj micro -bending attenuation, muaj feem xyuam rau tag nrho cov optical cable hom nrog rau ribbon cable.High anti-fatigue parameter xyuas kom meej kev pab cuam lub neej nyob rau hauv me me dabtsi yog khoov vojvoog.
• Daim ntawv thov:Tag nrho cov kev siv cable, 1260-1626nm puv band kis tau tus mob, FTTH kev kub ceev kho qhov muag routing, kho qhov muag cable nyob rau hauv me me khoov vojvoog, me me-loj optical fiber cable thiab ntaus ntawv, L-band.
Qhov zoo:
G652D: Marginally qis attenuation thiab qis splicing poob, thaum splicing zoo li fibers. Muab cov cables ntev dua.
G657A2: me me cable thiab cords installation radii, muab rau tus nqi qis installation, miniaturization thiab siab dua connectorization.
G657A2 optical fiber nyob rau hauv thaj cords muab ib tug txhim kho khoov vojvoog thiab yooj, uas yuav tso cai rau kom zoo dua cable tswj thiab routing nyob rau hauv congested cheeb tsam. Qhov khoov lub vojvoog tau zoo tuaj yeem tso cai rau kom muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. G657A2 optical fiber tau dhau los ua neeg nyiam heev hauv Data Center thiab Enterprise network xa tawm.
G.657.A1 vs G.657.A2
G.657.A2 kuj tau ua raws li G.652.D thaum muaj qhov nruj me ntsis khoov vojvoog ntawm 7.5mm, piv rau 10mm rau G.657.A1.
Vim tias nws txoj kab nkhaus nruj dua thiab ua raws li G.652.D, G.657.A2 yog qhov nrov siv rau hauv qhov chaw nruj dua nyob rau hauv qhov siab ceev patching teb hauv cov ntaub ntawv chaw. Ntau ntawm peb cov neeg siv khoom los ntawm cov tuam txhab kev sib txuas lus loj kuj tau thov G.657.A2 rau tib lub laj thawj.
Thaum siv G.657.A2, nws raug nquahu kom siv qhov tsawg tshaj plaws cable sheath txoj kab uas hla yog li ntawd lub sheath tsis txwv cov cables yam tsawg kawg nkaus khoov vojvoog. Ib yam li ntawd, luv luv booted connectors kuj tau teev tseg raws li feem ntau qhov nruj tshaj plaws khoov yog nyob rau ntawm qhov chaw txuas. Rau cov laj thawj zoo sib xws ntawm kev tswj hwm kev ua tau zoo thiab ua kom tau txais txiaj ntsig zoo ntawm kev siv G657.A2 fiber ntau, cov cables no tau ua nrog qis qis ferrule thiab polished los muab IL (ib txwm)<0.15dB and <0.20dB (Max).
G652D thiab G657A2 specifications xa mus rau lub iav thiab cable kev tsim kho ntawm optical fiber thiab feem ntau yog cov fibers ntawm kev xaiv nyob rau hauv optical fiber thaj ua rau singlemode systems.
ITU-T G652D singlemode fibers tau siv nyob rau hauv tag nrho cov tes hauj lwm rau ntau tshaj 30 xyoo. Ua rov qab sib xws, qhov no ua rau kev kho kom yooj yim dua / kho (spling fibers ntawm tib hom). G652D fiber ntau hom Field Diameter yog 10.4µm @ 1550nm.
G652D fibers muab kev sib kis qis qis dua, uas yog qhov zoo dua rau kev yooj yim rau kev sib txuas lus nyob deb (txog thiab ntau dua 100km).
Txawm li cas los xij, G652D fibers tau txwv khoov tsis kam.
G657A2 fibers yog siv nyob rau hauv advanced nkag cable network installation, qhov twg siab dua khoov kuj yuav tsum tau rau me me cable sib txuas pits thiab kuj tso cai rau cable thiab hardware miniaturisation.
G657A2 fibers tau siab tshaj G652D fibers. G657A2 fiber ntau hom Field Diameter yog 9.8µm @ 1550nm. Splice poob yog me ntsis siab dua thaum splicing ob lub fibers sib txawv ua ke.
G657A2 fiber ntau muaj kev tiv thaiv ntau dua rau dabtsi yog khoov (macrobend) poob (saib daim duab hauv qab), thiab ua kom yooj yim rau cov txheej txheem xa tawm nqi qis.
G657A2 - Khoov Intensive Fiber
G657A2 yog ib qho ntawm plaub qhov tshwj xeeb tau teev tseg los ntawm ITU-T nyob rau hauv qeb G657. Qhov no version muab cov ntaub ntawv hais txog kev tsim kho khoov fiber ntau thiab kho qhov muag fiber ntau cables. Yog li, G657A2 cables yog siv rau hauv kev sib txuas network qhov twg siab dua khoov yog tsim nyog. G657A2 yog ib qho kev daws teeb meem zoo rau kev nkag mus rau cov tes hauj lwm uas nquag khoov thiab koom nrog cov cables thiab kho vajtse miniaturization tau pom. Ntawm no, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias G657A2 fibers tau sib haum nrog G657D fibers.
Cov txiaj ntsig ntawm G657A2 fibers
Zoo tagnrho rau me me cable installation radii
Nqi-zoo rau kev nkag mus network
Txhawb cov ntawv thov ceev dua thiab miniaturization
Muab kev txhim kho yooj
