Yuav ua li cas yog kho qhov muag fibers cais?

 

Kev faib tawm los ntawm kev faib tawm hom: Ib {- hom fiber (smf) thiab multi- hom fiber (MMF).

●Sing - hom fiber ntauMuaj ib tug me ntxhais txoj kab uas hla thiab tuaj yeem hloov ib hom teeb.

● Multi - hom fiber ntaumuaj cov tub ntxhais loj loj loj dua thiab tuaj yeem kis ntau yam ntawm lub teeb.

 

Koj kuj tuaj yeem paub qhov txawv ntawm ib qho - hom thiab multi {1} hom xim los ntawm lawv cov xim sab nraud:

●Ib Leeg - hom fiber ntau feem ntau muaj lub tsho daj nrog cov kab txuas xiav, thiab cov cheeb tsam tub ntxhais ntawm 9.0 μm.

 

Nws ua haujlwm ntawm ob qhov nruab nrab wavelengths: 1310 nm thiab 1550 nm.

●1310 nmfeem ntau siv rau luv luv, nruab nrab, lossis ntev - deb kis.

●1550 nmyog siv rau ntev - deb thiab ultra - ntev} ntev muaj kev kis.

 

Kis mus deb yog nyob ntawm lub moduical kho qhov muag tau txais khoom siv hluav taws xob:

●1310 NM SMF chaw nres nkojKev them nyiaj yug los ntawm10 km, 30 km, 40 km, thiab lwm yam.

●1550 nm smf chaw nres nkojKev them nyiaj yug los ntawm40 km, 70 km, 100 km, thiab lwm yam.

Multi - hom fiber ntaufeem ntau muaj ib qhoTxiv kab ntxwv / grey tsho nrog dub / beige connector, thiab ib tug tub sab uas lub cheeb ntawm50.0 μm lossis 62.5 μm.

Nws central yoj yog feem ntau850 nm.Mmf muaj qhov sib kis luv luv, feem ntautsis pub dhau 500 m.

 

Kev faib tawm raws li i6 - t thoob ntiaj teb txheej txheem: G.651, G.653, G.654, G.656, G.657.
