Whakaahuatanga Hua
1. Whakarāpopototanga Hua
SA1300CKo nga raupapa o waho ko te whakakorikori kātua-a-waho ko te whakakaha hou-nui kua whakawhanakehia. Hoahoa taiawhio pakeke me te arotau, te mahi putaiao me te whaitake o roto me nga rauemi o te kounga kairangi, kia mau te hua me te iti o te pakaru. Ko te mea pai rawa atu mo te hanga i te kupenga tuku-a-rua CATV nui, waenga-rahi ranei.
2. Ahuatanga Mahinga
- Ko te ara whakamua i mua i te atamira ka tango i te taupae teitei hou rawa atu i kawemai i te waahanga whakakaha pana-pull haruru iti, i te waahanga pana-pull GaAs ranei, ka tangohia e te wahanga whakaputa te tohu teitei hou o te mana kawemai takirua.ykōwae tīwerawera, kōwae whakanui GaAs rānei. He pai te taupū kore raina, he pai ake te taumata whakaputa. Ko te ara hokinga e mau ana i te taupū teitei hou rawa mai i kawemai i te kōwae whakakaha kua whakatapua. He iti te paheketanga, he teitei te tohu ki te haruru.
- He watea ake ki te patuiro na te tātari matarua mono-mai, mono-mai (ka taea te whakarite) whakahōrite me te attenuator, me nga tauranga rangahau-a-ipurangi me te whaitake.
- Ka taea e nga taputapu te mahi tonu i raro i nga ahuatanga kino o waho. Na te mea ko te whare parewai konumohe, he nui te pono o te whakawhiti hiko me te punaha tiaki uira.
- Ko te anga e mau ana i te hoahoa modular kua whakauruhia; he watea te tiaki taputapu, te whakakapi, me te patuiro.
3. Aratohu Whakatau
Tena koa whakau: hononga whakarunga me te hononga whakararo te wehenga o nga huarahi ara-rua.
4. Tohutohu Motuhake:
- I mua i te whakamahi i te hua me tika te turanga!
- Ko te 10A te kaha o te kaha o te hua.
