Kev Paub Txog PON Optical Modules
Optical modules tuaj yeem muab faib ua ob pawg, cov ntaub ntawv sib txuas lus optical modules thiab PON optical modules. Cov ntaub ntawv kev sib txuas lus kho qhov muag modules yog peb cov khoom siv kho qhov muag ntau dua, uas feem ntau yog siv hauv kev lag luam tes hauj lwm, cov chaw zov me nyuam, cov chaw nres tsheb hauv paus, thiab lwm yam; thiab PON optical modules yog siv nyob rau hauv kev nkag network (PON system).
PON optical module yog dab tsi?
PON optical module yog ib qho kev ua haujlwm siab kho qhov muag siv hauv PON system, tseem hu ua PON module, raws li ITU-T G. 984.2 tus qauv thiab Daim Ntawv Pom Zoo Ntau Yam (MSA), uas siv cov wavelengths sib txawv xa thiab tau txais cov cim ntawm OLT (Optical Line Terminal) thiab ONT (Optical Network Terminal).
Kev faib tawm ntawm PON Optical Modules
① cais los ntawm kev sib kis raws tu qauv
Raws li txoj cai kis tau tus mob, PON optical modules tuaj yeem muab faib ua plaub hom: APON (ATM PON) optical modules, BPON (Broadband Passive Network) optical modules, EPON (Ethernet) optical modules thiab GPON (Gigabit Passive Network) optical modules. Feem ntau siv yog EPON optical modules thiab GPON optical modules.
② cais los ntawm pob
Feem ntau ntawm cov optical modules siv nyob rau hauv fiber-rau-lub-tsev kis tau tus mob uas peb feem ntau hais yog PON modules, thiab kev khiav hauj lwm wavelength feem ntau yog 1310nm / 1490nm, thiab muaj SFF pob, SFP pob, SFP + pob thiab XFP pob.
Nta ntawm PON Optical Modules
Kev sib kis dav dav ntawm PON modules tsuas yog 10KM lossis 20KM. Tsis zoo li cov qauv kho qhov muag ib txwm siv, uas yog siv ua khub, PON optical modules feem ntau tsis siv ua khub. Hom interface feem ntau yog SC interface, thiab tus nqi ua haujlwm feem ntau yog gigabit lossis 10G. Raws li ib qho ntawm cov khoom siv tseem ceeb ntawm fiber ntau-rau-lub tsev, PON optical module tau dav siv hauv kev nkag mus rau network.
