1. Chidule cha Zamalonda
SA1300CChojambulira cha trunk chakunja chozungulira mbali zonse ziwiri ndiye chojambulira chatsopano chopangidwa ndi high-gain amplifier. Kapangidwe ka dera kokhwima komanso kokonzedwa bwino, njira yasayansi komanso yomveka bwino yamkati komanso zipangizo zapamwamba, zimaonetsetsa kuti phindu likhale lokhazikika komanso kusokonekera kochepa. Ndi chisankho chabwino kwambiri chomangira netiweki yayikulu kapena yapakati ya CATV yozungulira mbali zonse ziwiri.
2. Makhalidwe Abwino
- Gawo lakutsogolo limagwiritsa ntchito gawo laposachedwa kwambiri lotchedwa high index lolowera kunja lotchedwa low noise push-pull amplifier kapena gawo la GaAs push-pull, gawo lotulutsa limagwiritsa ntchito mphamvu yatsopano kwambiri yolowera kunja yotchedwa high index.ygawo la amplifier kapena gawo la amplifier la GaAs. Chizindikiro chosakhala cha mzere ndi chabwino ndipo mulingo wotuluka ndi wokhazikika. Njira yobwerera imagwiritsa ntchito gawo la amplifier laposachedwa kwambiri lochokera kunja. Kusokonekera ndi kochepa ndipo chiŵerengero cha chizindikiro ndi phokoso ndi chachikulu.
- Ndikosavuta kukonza zolakwika chifukwa cha fyuluta ya duplex yolumikizira, cholumikizira chokhazikika (kapena chosinthika) cha plug-in ndi chochepetsera, komanso madoko ozindikira asayansi komanso oyenera pa intaneti.
- Zipangizozi zimatha kugwira ntchito mosalekeza kwa nthawi yayitali ngakhale panja pakakhala nyengo yoipa. Chifukwa cha nyumba ya aluminiyamu yosalowa madzi, magetsi osinthika odalirika komanso njira yoteteza mphezi mwamphamvu.
- Chipolopolocho chimagwiritsa ntchito kapangidwe kake ka modular; kukonza zida, kusintha, ndi kukonza zolakwika n'kosavuta.
3. Buku Lotsogolera Kuyitanitsa
Chonde tsimikizirani: kuchuluka kwa njira zolumikizirana pakati pa ma uplink ndi downlink zomwe zimagawidwa mbali zonse ziwiri.
4. Malangizo Apadera:
- Musanagwiritse ntchito mankhwalawa, muyenera kukhala ndi maziko odalirika!
- Mphamvu yayikulu kwambiri ya chinthucho ndi 10A.
