Isingeniso se-PON Module

Imojula ye-PON iwuhlobo lwemojuli yokubona.Isebenza kumishini yetheminali ye-OLT futhi ixhuma nemishini yasehhovisi ye-ONU.Kuyingxenye ebalulekile yenethiwekhi ye-PON.Amamojula we-PON optical angahlukaniswa abe amamojula optical APON (ATM PON), BPON (broadband passive network) optical modules, EPON (Ethernet) optical modules, kanye neGPON (gigabit passive network) amamojula optical ngokusho kwephrothokholi yokudlulisela.Njengamanje, amamojula we-EPON optical kanye namamojula optical we-GPON asetshenziswa kakhulu.Umfanekiso olandelayo ubonisa imojuli ye-GPON yokubona.   Ingxenye yokudlulisela ye-PON optical module ikumodi eqhubekayo.I-OLT ithumela isignali kagesi ngezinga elithile elincane ngomunwe wegolide wemojuli, futhi ishayela idivayisi ye-BOSA ukuze idlulisele isignali ye-optical modulated ngenani elihambisanayo ngemva kokucutshungulwa yi-chip yomshayeli ngaphakathi kwemojula.Imojula inomsebenzi we-alamu wokuqapha wedijithali, ongalawula ngokuzenzakalelayo umjikelezo futhi ugcine ukuzinza kwesignali ye-optical okukhiphayo.Imojula ye-PON ikhipha ukukhanya ku-1490nm.
Ingxenye eyamukelayo ye-PON optical module ikumodi yokuqhuma.Lapho imojuli ithola isignali yokubona ngenani elithile lekhodi, i-optical discovery diode yemojuli iguqula ukukhanya okutholiwe kube isignali kagesi, ekhuliswa i-preamplifier bese ikhipha isignali kagesi ngenani lekhodi elihambisanayo kutheminali ye-OLT. .Ubude begagasi bokukhanya obutholwe imojuli ye-PON ngu-1310nm. Imojula ye-PON ngokuvamile inebanga lokudlulisela elingu-10KM noma 20KM kuphela.Uhlobo lwesixhumi esibonakalayo ngokuvamile luyisixhumi esibonakalayo se-SC, futhi izinga lokusebenza ngokuvamile yi-gigabit noma i-10 gigabit.I-PON optical module, njengenye yezesekeli ezidingekayo ze-FTTH, isetshenziswa kakhulu kumanethiwekhi okufinyelela. Okungenhla Isingeniso Semojula ye-PON evelaI-Shenzhen HDV Phoelectron Technology Co., Ltd.
