(i) Nruab nrab wavelength
Kev ua haujlwm wavelength ntawm optical module yog qhov tseeb, tab sis yuav muaj qhov sib txawv ntawm ib hom thiab ntau hom. Tom qab ntawd cov lus qhia feem ntau muaj npe raws li qhov nruab nrab wavelength.
Chav tsev ntawm nruab nrab wavelength yog nanometer (nm),
Qhov nruab nrab nruab nrab wavelengths yog 850nm, 1310nm thiab 1550nm, thiab lwm yam.
1) 850nm (MM, ntau hom, tus nqi qis (cov khoom siv kho qhov muag yog pheej yig dua) tab sis luv luv kis tau tus mob (ntau hom kis tau tus mob, kev sib raug zoo ntawm cov wavelengths sib txawv), feem ntau tsuas yog 500m rau 3KM);
2) 1310nm (SM, ib hom, poob loj thaum kis tau tus mob, yooj yim nqus zog los ntawm nruab nrab tab sis me me dispersion, feem ntau siv rau kev sib kis hauv 40km);
3) 1550nm (SM, ib hom, poob me ntsis tab sis loj dispersion thaum lub sij hawm kis tau tus mob, feem ntau yog siv rau kev sib kis mus ntev tshaj 40km, mus txog 120km yam tsis muaj relay).
(ii) Kev sib kis nrug
Vim hais tias cov fiber ntau optical nws tus kheej muaj kev phiv xws li dispersion, poob, thiab kev nkag mus rau lub teeb liab optical. Yog li ntawd, qhov kev ncua deb uas lub teeb tawm los ntawm ntau hom teeb pom kev tuaj yeem mus txawv tebchaws. Thaum txuas optical interfaces, xaiv optical modules thiab optical fibers raws li qhov deb tshaj qhov teeb liab kis tau tus mob. Qhov kev ncua deb ntawm optical module muab faib ua peb hom: luv luv, nruab nrab nrug thiab ntev-ntev. Nws feem ntau suav hais tias 2km thiab qis dua yog qhov luv luv, 10 txog 20km yog qhov nruab nrab, thiab 30km thiab siab dua yog qhov ntev.
(iii) Tus nqi kis tau tus mob
Tus nqi sib kis yog hais txog tus lej ntawm cov khoom (ntsis) ntawm cov ntaub ntawv xa mus rau ib ob, hauv bps. Tus nqi kis tau tus mob tsawg li 100M, mus txog 400Gbps, thiab cov nqi siv feem ntau yog 155Mbps, 1.25Gbps, 10Gbps, 25Gbps, 40Gbps, 100Gbps thiab lwm yam. Tsis tas li ntawd, muaj peb tus nqi ntawm 2Gbps, 4Gbps thiab 8Gbps optical modules nyob rau hauv optical storage system (SAN).
Cov saum toj no yog kev paub txog peb qhov tseem ceeb parameters ntawm optical modules coj los ntawm Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. Cov khoom module tsim los ntawm lub tuam txhab npog optical fiber modules, Ethernet modules, optical fiber ntau transceiver modules, optical fiber nkag modules, SSFP optical modules, thiabSFP optical fibers, thiab lwm yam. Cov khoom lag luam saum toj no tuaj yeem muab kev txhawb nqa rau cov xwm txheej sib txawv. Ib pab neeg R & D muaj zog thiab muaj zog tuaj yeem pab cov neeg siv khoom nrog cov teeb meem kev lag luam, thiab pab pawg ua lag luam muaj kev xav thiab kev ua haujlwm tuaj yeem pab cov neeg siv khoom tau txais kev pabcuam zoo thaum lub sijhawm sib tham ua ntej thiab ua haujlwm tom qab tsim khoom. Zoo siab txais tos koj tiv tauj peb rau txhua yam kev nug.
