Tsanangudzo Pfupi
Iyi transmitter ndeye yakakwirira-indekisi, yakawanda-inoshanda 1550nm yemukati modulated optical transmitter padanho repamusoro. Iyo inotora yakakwira mutsara DFB laser, ine yakavakirwa-mukati-yakakanganiswa muripo uye AGC, APC, uye ATC kutonga, iyo inovandudza zvakanyanya indekisi yakazara yehurongwa.
ST1550I yakatevedzana 1550nm yemukati modulated optical transmitter ndiyo musimboti mudziyo wekuvakwa kweCATV sekondari kutapurirana network. Inonyanya kushandiswa kune zvakakosha-akawedzera masevhisi akadai seTV masaini masaini, madhijitari masaini eTV, masaini enhare, uye data (kana akadzvanywa data) masaini. Iyo yemhando yepamusoro asi ine mutengo wakaderera mhinduro yekuona katatu kutamba uye FTTx network yekufambisa masisitimu.
Functional Features
1. Inotora yepakutanga yakaderera chirp uye yakakwirira mutsara DFB laser sechiratidzo sosi.
2. Iyo yakakwana pre-distortion circuit inovimbisa kushanda kwakakwana kweCTB neCSO muhutano hwepamusoro hweCNR.
3. Kuwana otomatiki (AGC) kutonga kunogonesa kubuda kwakagadzikana mumatanho akasiyana eRF ekuisa.
4. Mishonga yakasiyana inogona kugadziriswa neOMI kugadzirisa.
5. Fully otomatiki nyaya tembiricha control, akangwara mafeni, mafeni anotanga kushanda kana nyaya tembiricha asvika 30 ℃.
6. Yakavakwa-mukati maviri backup simba rekushandisa, inopisa plug, uye otomatiki switch inotsigirwa.
7. Zvishandiso zvekushanda zvemuchina wose zvinotungamirirwa ne microprocessor uye LCD mamiriro ekuratidza panhizha yepamberi ine mabasa akawanda akadai se laser status monitoring, parameter display, fault alarm, network management, nezvimwewo; kana maparamendi ekushanda e laser atsauka kubva kune yakabvumidzwa renji yakaiswa nesoftware, sisitimu inovhundutsa nekukasira.
8. Standard RJ45 interface yakapiwa, inotsigira kure kure network management yeSNMP neWEB.
