Chiyambi
Cholandirira kuwala cha SRB series ndi cholandirira kuwala chamkati chopangidwa kuti chikwaniritse ntchito yokonzanso ulusi wa netiweki. Chogulitsachi chili ndi ma RF output ports 1 mpaka 2. Ndipo khazikitsani ntchito ya optical AGC pamene +2dBm ~ -6dBm ikalandira output ikhoza kusungidwa pa 106dBµV pamwamba (pawiri); chipolopolo pogwiritsa ntchito chipolopolo cha aluminiyamu chopangidwa ndi cast.
Zinthu Zogwira Ntchito
- 45MHz mpaka 1000MHz nsanja yolumikizirana ndi nsanja yopangira mawindo awiri ya 1310, 1550;
- Dongosolo labwino kwambiri loletsa kugwedezeka kwa mafunde ndi fyuluta yodutsa kwambiri, yolimbana kwambiri ndi mphezi komanso kupewa kugwedezeka kwa mafunde;
- kapangidwe kake kogwiritsa ntchito mphamvu zochepa, mphamvu yonse yogwiritsira ntchito ndi yochepera 15W; ndipo ili ndi chiwonetsero cha digito komanso ntchito yogwira ntchito pa intaneti.
- Ma transponder a mtundu wa II angagwiritsidwe ntchito ；
