1550nm Hoʻouna Optical waho
Ke hana nei kēia moʻo transmitter internal-modulated i ka hoʻololi ʻana i ka hōʻailona RF-to-optical ma 1550nm link transmission.
1U 19' hihia maʻamau me ka wai aniani hōʻike (LCD/VFD) ma mua o ka papa;
Ka bandwidth alapine: 47—750 / 862MHz;
Ka mana puka mai ka 4 a hiki i ka 24mw;
Kaapuni hoʻoponopono pre-distortion kiʻekiʻe;
AGC/MGC;
Kaapuni mana 'akomi (APC) a me ka kaapuni wela 'akomi (ATC).
Hiʻona Hoʻokomo ʻia ka modulator waho a me ka laser mai ʻAmelika Hui Pū ʻIa a i Iapana paha.
ʻO ke kaʻapuni pre-distortion maikaʻi loa e hōʻoia i ka CTB a me CSO maikaʻi loa i ka wā o ka CNR i ke kūlana kiʻekiʻe.
