Thaum peb xaiv ib qho kev kho qhov muag module, ntxiv rau qhov yooj yim ntim, kis nrug, thiab kis tus nqi, peb kuj yuav tsum tau them sai sai rau cov hauv qab no:
1. Hom fiber ntau
Fiber hom tuaj yeem muab faib ua ib hom thiab ntau hom. Qhov nruab nrab wavelengths ntawm ib hom optical modules feem ntau yog 1310nm thiab 1550nm, thiab lawv tau siv ua ke nrog ib hom optical fibers. Ib hom optical fiber ntau muaj qhov sib kis dav thiab muaj peev xwm kis tau tus mob loj, thiab tsim nyog rau kev sib kis mus ntev. Qhov nruab nrab wavelength ntawm multimode optical module feem ntau yog 850nm, thiab nws yog siv ua ke nrog multimode optical fiber. Multimode fiber ntau muaj modal dispersion tsis xws luag, thiab nws cov kis tau tus mob kev ua tau zoo tshaj ntawm ib hom fiber ntau, tab sis nws cov nqi yog tsawg, thiab nws yog haum rau me me peev xwm thiab luv luv kis tau tus mob.
2. Optical fiber ntau interface
Cov modules feem ntau suav nrog LC, SC, MPO, thiab lwm yam.
3. Ua haujlwm kub
Kev khiav hauj lwm kub ntawm qhov kho qhov muag module yog qib lag luam (0 ° C-70 ° C), qib txuas ntxiv (-20 ° C-85 ° C), thiab qib kev lag luam (-40 ° C-85 ° C). Optical modules nrog tib pob, tus nqi, thiab kev sib kis deb feem ntau muaj ob hom: qib kev lag luam thiab qib kev lag luam. Cov khoom lag luam-qib siv cov khoom siv nrog kev ua siab ntev zoo dua, yog li tus nqi ntawm cov khoom lag luam qib siab dua. Peb yuav tsum xaiv qhov kev khiav hauj lwm kub theem ntawm qhov kho qhov muag module raws li qhov chaw siv tiag tiag.
4. Ntaus Compatibility
Vim tias cov tuam txhab tsim khoom loj, txhawm rau muab cov khoom lag luam thiab cov kev pabcuam zoo ib yam, lawv txhua tus nyiam muaj kev kaw ecology. Yog li ntawd, optical modules tsis tuaj yeem sib xyaw nrog txhua hom khoom siv. Thaum peb yuav ib qho khoom siv kho qhov muag, peb yuav tsum tau piav qhia rau cov tub lag luam uas cov khoom siv kho qhov muag yuav tsum tau siv rau, kom tsis txhob muaj teeb meem ntawm cov khoom siv tsis sib xws hauv cov khoom siv kho qhov muag.
5. Nqe
Feem ntau, optical modules nrog tib lub npe raws li cov khoom siv hom khoom kim heev. Qhov kev ua tau zoo thiab kev ua tau zoo ntawm cov neeg thib peb tau tshaj optical modules tuaj yeem hais tau zoo ib yam li hom kho qhov muag modules tam sim no, tab sis tus nqi muaj qhov pom tseeb zoo.
6. Zoo thiab kev pab cuam tom qab muag
Feem ntau, yuav tsis muaj teeb meem nrog optical modules hauv thawj xyoo ntawm kev siv, thiab feem ntau ntawm lawv yuav tshwm sim tom qab. Yog li sim xaiv ib tus neeg muag khoom nrog cov khoom zoo.
