G.652 Txuj Ci Ib - hom fiber ntau (feem ntau siv)
Peculiarity:
Lub Xoom Dispersion taw tes yog nyob hauv 1310NM band, nrog kev faib tawm tsawg heev ntawm 1310NM (kwv yees li ntawm 15ps / (kwv yees li ntawm 17ps / (NAM KON)).
Qhov poob ntawm 1550nm yog tsawg (txog 0.2db / km), tab sis tus kis mob deb ntawm cov nqi siab (xws li 10gbps lossis ntau dua vim kev txwv tsis pub dhau los.
Qhov fibic fiber no nyob rau ntawm ob qho 1310 nm thiab 1550 nm wavelown raging, nrog nws txoj kev ua haujlwm zoo tshaj plaws hauv 1310 nm ntau.
SubTej: G.652A / B / C / C / C / C / C / C / C.652d txhawb nqa 1310Nm thiab 1550 xyoo} band muaj zog rau muaj zog.
Cov Kev Siv: Kev Siv Xov Xwm Backbone tes hauj lwm, nkag mus rau cov network, cov ntaub ntawv cov ntaub ntawv, yog qhov feem ntau siv ib qho {hom o} opt kho qhov muag.
G.652D yog cov qauv tseem ceeb tam sim no, muaj fiber}}}}}} {{{{10} {10} {10} {10}- lub qhov rai Kis, yoog raws cov chaw network nyuaj.
G.653 Kev Txom Nyem Cov Fiber Ntau (DSF)
Peculiarity:
Nws tau tsim los txhim kho siab - ceev taw kev xa khoom mus rau 1550nm band, noj rau hauv tus account qhov poob qis thiab xoom dispersion ntawm no band.
Muaj plaub - yoj sib xyaw (FWM) teeb meem, uas tuaj yeem ua rau cov phiajcim tsis sib xws (DWDM), txwv nws cov ntawv thov hauv cov khoom muaj peev xwm siab.
Daim ntaub ntawv thov: ib zaug siv rau ib qho - lane siab siab (xws li thaum ntxov 10GB hloov tshiab), nws tau hloov maj mam hloov los ntawm G.655.
G.654 Hlais - tawm wavelengud fiber ntau (ultra- qis fiber)
Peculiarity:
Qhov poob ntawm 1550nm yog tsawg heev (nqis tsawg dua 0.15db / km), ua nws qis tshaj plaws poob ntawm txhua tus qauv txheej txheem.
Nws muaj qhov siab txiav - tawm wavelength (feem ntau> ntxiv lawm 1530nm) thiab tsuas yog txhawb nqa kev sib kis zoo ib yam li G.652 (xoom dispersion ntawm 1310NM).
Cov ntawv thov: Ultra - ntev} ntev} Kev deb} Kev deb ntawm cov neeg rov qab muaj roj ntxiv) tuaj yeem txo tus lej ntawm cov nqi thiab txo tus nqi.
G.655 tsis - xoom dispersion mov fiber ntau (nz- DSF)
Peculiarity:
Qhov Pes Tsawg Li Dispersion Taw yog tsiv tawm ntawm 1550nm band, thiab ib qho me me ntawm kev dispersion (feem ntau}
SubTypes: Muab faib ua ntau cov pawg raws li kev sib cais ntau, yoog raws cov nqi sib txawv (piv txwv li, 10GBps, 100Gbps).
Daim ntawv thov: ntev {- nrug dewd
G.656 dav dav tsis - xoom} xoom dispersion fiber
Peculiarity:
Piv nrog G.655, nws txhawb nqa cov haujlwm dav (npog S, C, Land, txog 1460 ~}}} bardband DWDM.
Cov ntawv thov: Ultra - bdadband thiab ultra} Qhov muaj peev xwm ntev tshaj plaws kom tau raws li cov kev xav tau ntawm cov kev xav tau ntawm lub neej yav tom ntej.
G.657 nkhaus insensitive fiber ntau rau kev nkag mus
Peculiarity:
Tsim los siv cov tes hauj lwm, nws muaj zog bendion rillionance (khoov hluav taws xob me me li 5 hli lossis nws tsis yooj yim ua rau kev poob qis (xws li thaj chaw nyob sab hauv thiab chaw nqaim).
SubTypes: G.657A (Tau tshaj G.652, khoov li ntawm 10 hli), g.657b (ntau dua kev puas yog li 5 hli), thiab lwm yam.
Cov ntawv thov: Fiber - rau - {} {} kev sib txuas hauv tsev, thiab lwm yam xwm txheej.
