PON optical module yog ib qho kev ua haujlwm siab kho qhov muag siv hauv PON (passive optical network) system, tseem hu ua PON module, raws li ITU-T G.984.2 tus qauv thiab ntau qhov chaw raws tu qauv (MSA). Nws siv cov wavelengths sib txawv los xa thiab txais cov teeb liab ntawm OLT (optical kab davhlau ya nyob twg) thiab ONT (qhov chaw nres nkoj kho qhov muag) (cov teeb liab no yog kis los ntawm lub teeb tsis muaj zog). Cov qauv kev lag luam tam sim no yog: Downlink (OLT - ONU) yog kis ntawm 1490nm wavelength; Upstream (ONU - OLT) yog kis ntawm lub wavelength ntawm 1310nm.
Daim ntawv thov dav ntawm PON Ethernet passive optical network yog sib cais los ntawm PON optical module, vim nws yog ib feem tseem ceeb ntawm PON system. PON module feem ntau convertsOLThluav taws xob teeb liab rau hauv modulated optical teeb liab xa mus rauONU; Lub uplink yog kis mus rauOLTlos ntawm kev hloov cov teeb liab optical modulated los ntawmONUrau hauv hluav taws xob teeb liab. Optical fiber kis tau tus mob txoj kev ntawmOLTthiabONUtwb paub lawm.
Kev faib tawm ntawm PON modules: Tam sim no, ob hom PON modules feem ntau siv hauv kev lag luam tau muab faib ua:
GPON - Gigabit passive optical network
EPON - Ethernet passive optical network
Yog tias koj tsis xav txog tus nqi, koj raug qhia kom xaiv GPON network los muab kev pabcuam ntau dua thiab ua haujlwm zoo dua.
Cov saum toj no yog PON module kev paub piav qhia coj los ntawm Shenzhen HDV Phoeletron Technology LTD. Cov khoom lag luam module tsim los ntawm lub tuam txhab npog optical fiber module, Ethernet module, optical transceiver module, optical fiber nkag module, SSFP optical module, SFP optical fiber module thiab hais txog. Cov khoom siv hauv chav kawm saum toj no tuaj yeem muab kev txhawb nqa rau cov xwm txheej sib txawv. Rau cov khoom lag luam saum toj no, nws tau ua ke nrog cov kws tshaj lij thiab muaj zog R & D pab neeg los muab kev txhawb nqa rau cov neeg siv khoom, thiab pab pawg ua lag luam xav tau zoo los muab kev pabcuam zoo rau cov neeg siv khoom hauv kev sib tham thaum ntxov thiab tom qab ua haujlwm.
