Optical module yog cov cuab yeej ntawm tau txais cov teeb liab teeb nyob rau hauv cov hluav taws xob fiber ntau kis, uas yog siv los txuas ob lub tshuab hluav taws xob (xws li server, hloov, thiab lwm yam) ua ke nrog optical fiber. Raws li ntau hom kev tsim kho cov kab hluav taws xob, cov qauv kho qhov muag tau muab faib ua tib hom kho qhov muag thiab ntau hom kho qhov muag.
Txog ib hom teeb hom thiab ntau hom teeb lub teeb
Raws li lub npe cuam tshuam, tib hom hom teeb pom kev zoo yog lub teeb hluav taws xob siv nrog ib hom fiber ntau. LD lossis LED nrog cov kab hluav taws xob me me tau siv los ua cov khoom siv hluav taws xob, tuaj yeem sib kis tau cov ntaub ntawv bandwidth kawg, yog li cov kis tau mus ntev heev. Txawm li cas los xij, ntau hom kho qhov muag module siv ua ke nrog ntau hom kho qhov muag fiber ntau, uas siv cov teeb tsa hluav taws xob tso tawm lossis laser ua lub teeb ci, thiab qhov kis tau deb yog luv.
Qhov sib txawv ntawm cov tib hom teeb taws thiab ntau hom teeb lub teeb
Kev sib kis thiab qhov deb- ob qho tib hom thiab ntau hom kho qhov muag tuaj yeem pab txhawb 10G thiab 40G kis, tab sis kis tau sib txawv yog qhov sib txawv. Qhov siab tshaj plaws kis nrug ntawm ntau hom kho qhov muag module yog li ntawm 550 m, thaum qhov kev sib kis tau ntawm cov tib hom kho qhov muag tau ncav cuag 10 km, 40 km, 80 km lossis ntau dua.
Nqe - cov khoom siv uas siv ntau hom kho qhov muag coj tau ob zaug kim dua li cov tau siv ntau hom khoos phis tawm, yog li lawv kuj kim dua tus uas siv ntau hom kho qhov muag coj los kho.
Kev ua tau zoo - feem ntau hais lus, ib hom kho qhov muag tau siv tau tsuas yog siv tib hom optical fiber ntau, thiab ntau hom kho qhov muag tau siv tau nrog ntau hom kho qhov muag fiber ntau, tsis sib xyaw.
Kev siv hluav taws xob - lub zog siv ntawm ntau hom kho qhov muag hluav taws xob tau qis dua li ntawm ib-hom optical modules.
Kev siv tib hom / ntau hom kho qhov muag qauv
Thaum siv ib hom-ntau hom / ntau hom kho qhov muag, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
Xyuas kom meej tias cov khoom siv kho qhov muag ntawm ob qho kawg ntawm qhov txuas cov kab txuas tau ua haujlwm zoo tib yam wavelength; Txhawm rau txo cov pob ntawv poob cov ntawv poob, ntau hom kho qhov muag siv tau rau kev sib kis luv thiab tib hom kho qhov muag tau siv rau kev sib kis ntev. Tsis txhob khoov lub kho qhov muag hluav taws xob nruab nrab ntawm cov khoos phis tawm kho qhov muag kom tiv thaiv tau qhov kev ploj ntau tshaj.
