Ib hom Fiber: G652D vs G657A2

1/ Dab tsi yog ib hom fiber ntau?

+ Ib hom fiber ntau yog ib hom fiber ntau uas tsim los nqa tsuas yog ib hom teeb - hom transverse.

Ib hom fiber ntau ib hom muaj lub qhov tseem ceeb ntawm 8 txog 10.5 μm (feem ntau yog 9μm) thiab lub qhov cladding ntawm 125 μm.

+ OS1 thiab OS2 yog tus qauv 9/125 μm ib hom fiber optical. Ob leeg siv nrog wavelengths 1310 nm thiab 1550 nm.

+ Ib hom fiber yog tsim los rau kev sib kis mus ntev, ceev ceev, feem ntau txhawb nqa qhov deb ntawm 2 km txog 100–160 km.

Cov qauv ntawm ib hom fiber ntau ib hom:

Lub hauv paus:Txoj kab uas hla 8–9 μm

Kev Tiv Thaiv:Txoj kab uas hla 125 μm

Tsis txhob:Txoj kab uas hla 250 μm

Lub tsho loj:Txoj kab uas hla 600 lossis 900 μm

2/ G652D Ib Hom Fiber:

+ G652D Ib hom Fiber yog hom fiber ntau tshaj plaws (SMF), uas tau teeb tsa los ntawm ITU-T rau kev sib txuas lus ceev ceev, ntev.

+ Nws muaj cov thev naus laus zis "qis dej ncov", txo qhov poob ntawm lub teeb liab hauv 1383 nm wavelength ntau yam.

+ Paub txog qhov muaj bandwidth siab, qis attenuation, thiab rov qab sib xws, nws zoo tagnrho rau kev sib txuas lus hauv xov tooj, Metropolitan Area Networks (MAN), thiab Fiber rau Tsev (FTTH) daim ntawv thov.

3/ G657A2 Ib hom Fiber:

+ G.657A2 Ib hom Fiber yog ib qho fiber uas tsis yooj yim khoov, ib hom fiber uas ua raws li ITU-T cov qauv, tsim los ua haujlwm nrog qhov poob qis tshaj plaws ntawm qhov khoov nruj (qis li 7.5 hli).

+ Nws sib xws nrog G.652D fiber, ua rau nws zoo tagnrho rau cov xov hlau FTTH siab, cov xov hlau sab hauv tsev, thiab qhov chaw me me, qhov siab khoov-radius.
