Kufotokozera Mwachidule
Chotumizira ichi ndi chotumizira cha kuwala cha 1550nm chokhala ndi mainchesi ambiri, chogwiritsidwa ntchito m'njira zambiri pamwamba. Chimagwiritsa ntchito laser ya DFB yolunjika kwambiri, yokhala ndi chiwongola dzanja chomangidwa mkati mwa pre-distortion ndi AGC, APC, ndi ATC control, zomwe zimathandizira kwambiri index yonse ya dongosololi.
Chotumizira cha ST1550I cha 1550nm chosinthidwa mkati mwa makina owunikira ndiye chida chachikulu chopangira ma netiweki achiwiri a CATV. Chimagwiritsidwa ntchito makamaka pa ntchito zowonjezera phindu monga zizindikiro za zithunzi za pa TV, zizindikiro za pa TV ya digito, zizindikiro za pafoni, ndi zizindikiro za data (kapena deta yokakamizidwa). Ndi njira yabwino koma yotsika mtengo yopezera njira zitatu zotumizira ma netiweki a FTTx.
Zinthu Zogwira Ntchito
1. Imagwiritsa ntchito laser yoyambirira ya DFB yotsika komanso yolunjika kwambiri ngati gwero la chizindikiro.
2. Dongosolo loyenera la pre-distortion limatsimikizira kuti CTB ndi CSO zimagwira ntchito bwino kwambiri pamtengo wapamwamba wa CNR.
3. Kuwongolera kwa automatic gain (AGC) kumathandiza kutulutsa kokhazikika m'magawo osiyanasiyana olowera a RF.
4. Ma network osiyanasiyana amatha kukonzedwa bwino pogwiritsa ntchito kusintha kwa OMI.
5. Kuwongolera kutentha kwa chikwama choyaka chokha, mafani anzeru, mafani amayamba kugwira ntchito kutentha kwa chikwamacho kukafika pa 30 ℃.
6. Mphamvu yolumikizira yomangidwa mkati mwa ziwiri, pulagi yotentha, ndi switch yodziyimira yokha yothandizidwa.
7. Ma parameter ogwirira ntchito a makina onse amayendetsedwa ndi microprocessor ndipo chiwonetsero cha LCD chomwe chili kutsogolo chili ndi ntchito zambiri monga kuyang'anira momwe zinthu zilili ndi laser, kuwonetsera momwe zinthu zilili, alamu yolakwika, kasamalidwe ka netiweki, ndi zina zotero; magawo ogwirira ntchito a laser akasintha kuchokera pamlingo wololedwa womwe wakhazikitsidwa ndi pulogalamuyo, dongosololi lidzachenjeza nthawi yomweyo.
8. Mawonekedwe a RJ45 okhazikika amaperekedwa, othandizira kasamalidwe ka netiweki yakutali ya SNMP ndi WEB.
