G652D

I. Txheej txheem cej luam ntawm G652D Fiber Optic
G652D fiber ntau, lossis tus qauv ib zaug -mode fiber (SMF), yog hom fiber ntau siv hauv kev sib txuas lus. Nws yog qhov tsim nyog rau qhov ntev - nrug, siab - lub teeb liab kis tau tus mob ceev, uas muaj qhov txo qis, tsis muaj kev tawg, thiab muaj peev xwm tiv thaiv zoo - cuam tshuam. G652D fiber ntau tuaj yeem ua tau raws li kev xav tau ntawm kev sib txuas lus tam sim no thiab yog ib qho tseem ceeb hauv kev tsim cov kev sib txuas lus niaj hnub no.

II. Kev piav qhia ntxaws ntawm G652D Fiber Parameters

1. Attenuation

Attenuation yog ib qho tseem ceeb tsis zoo ntawm fiber ntau optic kis tau tus mob, sawv cev rau lub zog poob ntawm optical teeb liab thaum kis tau tus mob. Tus nqi attenuation rau G652D fiber ntau yog 0.34 dB / km ntawm 1310 nm thiab 0.20 dB / km ntawm 1550 nm. Cov yam ntxwv qis qis qis no ua rau G652D fiber ntau kom ua tiav ntev dua -kev sib kis tsis tu ncua, txo tus nqi ntawm kev sib txuas lus.

2.Mode Field Diameter (MFD)
Hom teb txoj kab uas hla yog ib qho parameter piav txog qhov luaj li cas ntawm lub teeb qhov chaw nyob rau hauv lub fiber, thiab nws muaj ib tug tseem ceeb cuam tshuam rau kev sib txuas thiab coupling efficiency ntawm fiber. Hom teb txoj kab uas hla ntawm G652D fiber ntau yog 9.2 ± 0.4 μm ntawm lub wavelength ntawm 1310 nm. Ib txoj kab uas haum hom teb pab txo cov teeb liab optical tawg thiab poob, txhim kho kev ua tau zoo thiab ruaj khov ntawm kev sib kis ntawm fiber ntau.

3.Dispersion Coefficient: Lub dispersion coefficient yog ib qho parameter uas ntsuas qhov sib txawv ntawm kev sib kis ceev ntawm optical signals ntawm txawv wavelengths nyob rau hauv ib tug optical fiber. Nyob rau hauv G652D fiber ntau, optimizing lub dispersion coefficient pab txo distortion thiab ncua thaum lub teeb liab kis tau tus mob. Tshwj xeeb, nyob ze ntawm lub wavelength ntawm 1550 nm, dispersion coefficient ntawm G652D fiber ntau yog tsim tshwj xeeb los txo cov mem tes broadening thiab teeb liab distortion, yog li ua kom siab - zoo teeb liab kis tau tus mob.

4.Cutoff Wavelength: Lub cutoff wavelength yog hais txog lub siab tshaj plaws wavelength ntawm ib zaug -mos teeb uas yuav propagate nyob rau hauv ib tug optical fiber. Rau G652D fiber ntau, qhov txiav tawm wavelength feem ntau yog tsim los ua 1260 nm. Qhov no txhais tau hais tias kev sib kis ntau hom yuav tshwm sim ntawm wavelengths hauv qab 1260 nm, thaum ib zaug - kis tau tus mob yog lav ntawm wavelengths saum 1260 nm. Qhov tsim nyog txiav tawm wavelength teeb tsa pab xyuas kom muaj kev sib kis ntawm cov fiber ntau nyob rau hauv ib qho kev qhia wavelength.

III. Kev siv thiab kev txhim kho ntawm G652D Fiber Optics

G652D fiber ntau optics, nrog nws cov kev sib kis tau zoo thiab kev siv dav, tau siv dav hauv ntau qhov chaw xws li kev sib txuas lus, tshaj tawm, thiab cov chaw zov me nyuam. Nrog rau kev txhim kho txuas ntxiv ntawm kev sib txuas lus thev naus laus zis, G652D fiber optics yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev tsim kom siab - nrawm, siab - muaj peev xwm, thiab qis- latency kev sib txuas lus. Ib txhij, hauv kev teb rau kev hloov pauv kev xav tau kev sib txuas lus yav tom ntej, thev naus laus zis tshiab thiab hloov kho tshiab ntawm G652D fiber optics yuav txuas ntxiv mus ua kom tau raws li qhov xav tau ntawm kev sib txuas lus ntau ntxiv.
