1. Chidule cha Zamalonda

ZBR1001JL kuwala wolandila ndi 1GHz FTTB kuwala wolandila atsopano. Ndi mitundu yambiri yolandila mphamvu yamagetsi, kuchuluka kwakukulu komanso kugwiritsa ntchito mphamvu zochepa. Ndi zida zabwino zomangira ma network a NGB omwe amachita bwino kwambiri.

2. Magwiridwe antchito

■ Njira yabwino kwambiri yoyang'anira ma AGC, pomwe magetsi amtundu walipo -9+ +2dBm, kuchuluka kwake, CTB ndi CSO kwenikweni sizinasinthe;

■ Downlink ntchito pafupipafupi yowonjezera 1GHz, gawo lama RF amplifier limagwira ntchito yayikulu yogwiritsira ntchito mphamvu zochepa za GaAs chip, zotulutsa kwambiri mpaka 112dBuv;

■ EQ ndi ATT onse amagwiritsa ntchito makina oyang'anira magetsi, zimapangitsa kuti kulamulira kukhale kolondola, kugwira ntchito mosavuta;

■ Omangidwa munthawi yadziko mayankho oyang'anira magulu aukadaulo wachiwiri, kuthandizira kasamalidwe kakutali kanyumba (ngati mukufuna);

■ Kapangidwe kakang'ono, kosavuta kukhazikitsa, ndiye zida zoyambira kusankha pa intaneti ya FTTB CATV;

■ Kumanga kodalirika kogwiritsira ntchito mphamvu zamagetsi, komanso magetsi akunja osankhidwa;

6. Njira yoyera ndi kukonza kwa cholumikizira cha fiber cholumikizira

Nthawi zambiri, timaganiza molakwika kuchepa kwa mphamvu yamagetsi kapena kuchepa kwa mulingo wolandila ngati zida zolakwika, koma mwina zimatha chifukwa cha kulumikizana kolakwika kwa cholumikizira cha fiber kapena cholumikizira cha fiber chawonongedwa ndi fumbi kapena dothi.

Tsopano yambitsani njira zodziwika bwino zowakonzera zolumikizira zamagetsi.

1.Sungani mosamala cholumikizira cholumikizira cholumikizira kuchokera ku adaputala. Cholumikizira cholumikizira cholumikizira sichiyenera kutengera thupi la munthu kapena maso kuti asavulale mwangozi.

2.Sambani mosamala ndi mapepala abwino opukuta mapepala kapena mankhwala ochotsera thonje. Ngati mukugwiritsa ntchito thonje wachakumwa wachipatala, mukufunikirabe 1 ~ 2 mphindi mukatsuka, lolani cholumikizira chiume mlengalenga.

3.Cholumikiza cholumikizira cholumikizira cholumikizira chikuyenera kulumikizidwa ndi mita yamagetsi yamagetsi kuti muyese mphamvu yamagetsi yotsimikizira ngati yatsukidwa.

4.Wrew kagwere cholumikizira CHIKWANGWANI chamawonedwe cholumikizira ku adapter, azindikire kuti gulu loyenera lipewe chubu la ceramic mu adapter.

5.Ngati mphamvu yamagetsi yamagetsi siyachilendo pambuyo poyeretsa, iyenera kutulutsa adapter ndikutsuka cholumikizira china. Ngati mphamvu yamagetsi ikadali yotsika pambuyo poyeretsa, adapter imatha kuipitsidwa, yeretseni. (Dziwani: Samalani mukamachotsa adaputala kuti musavulaze mkati mwa fiber.

6. Gwiritsani odzipereka wothinikizidwa mpweya kapena degrease mowa thonje bala kuyeretsa adaputala. Mukamagwiritsa ntchito mpweya wothinikizidwa, mphuno ya thanki yothinikizidwa iyenera kuyang'ana pa chubu cha ceramic cha adaputala, kuyeretsa chubu cha ceramic ndi mpweya wopanikizika. Mukamagwiritsa ntchito digirii ya mowa yopangira mowa, ikani mosamala mowa wapa thonje mu chubu cha ceramic kuti muyere. Malangizo owongolera ayenera kukhala osagwirizana, apo ayi sangathe kufikira kuyeretsa koyenera.

7. Pambuyo pogulitsa ntchito

1.Timalonjeza: Chitsimikizo chaulere cha miyezi khumi ndi itatu (Siyani nthawi yakufakitala chikalata cha ziyeneretso za mankhwala monga tsiku loyambira). Nthawi yowonjezera yotsimikizika kutengera mgwirizano wamgwirizano. Tili ndi udindo wokonza moyo wathu wonse. Ngati vuto lazida zikuchitika chifukwa chogwiritsa ntchito molakwika kwa ogwiritsa ntchito kapena zifukwa zosapeweka zachilengedwe, tidzayang'anira kukonza koma kufunsa mtengo woyenera.

2.Zida zikawonongeka, nthawi yomweyo imbani foni yathu yothandizira pa 8613675891280

3. Kukonzekera kwa malo pazida zolakwika kuyenera kuyendetsedwa ndi akatswiri kuti apewe kuwonongeka koopsa.

Chidziwitso chapadera: Ngati zida zakhala zikusamalidwa ndi ogwiritsa ntchito, sitikhala ndi udindo wosamalira zaulere. Tifunsa mtengo woyenera wosamalira ndi mtengo wakuthupi.
