• Pa nthawi yomweyo amapereka ma voltage asanu ndi limodzi a automatic bias a Dual Polarization IQ modulators
• Kapangidwe ka modulation kopanda tsankho:
SSB, QPSK, QAM, OFDM yatsimikiziridwa.
• Pulagi ndi Kusewera:
Palibe chifukwa chowerengera pamanja. Chilichonse chimachitika chokha.
•I, Q arms: controll pa Peak ndi Null modes Chiŵerengero chachikulu cha kutha kwa madzi:50dB max1
•P arm: controll pa Q+ ndi Q- modes Kulondola: ± 2◦
•Mawonekedwe otsika: 40mm(W) × 29mm(D) × 8mm(H)
•Kukhazikika kwambiri: kugwiritsa ntchito digito kwathunthu. Zosavuta kugwiritsa ntchito:
•Kugwiritsa ntchito ndi manja ndi mini jumper 2
Ntchito zosinthika za OEM kudzera mu UART / IO
•Ma mode awiri operekera ma voltage a bias: a. Automatic Bias Control b. User defined bias voltage
Kugwiritsa ntchito
•LiNbO3 ndi ma modulators ena a DP-IQ
• Kutumiza Kogwirizana

1 MER imatanthauza chiŵerengero cha kutha kwa Modulator. Chiŵerengero cha kutha kwa zinthu chomwe chimapezedwa nthawi zambiri chimakhala chiŵerengero cha kutha kwa modulator chomwe chafotokozedwa mu datasheet ya modulator.
2LolaniVπ sonyezani mphamvu ya bias pa 180◦ ndiVP kusonyeza mphamvu ya bias yabwino kwambiri pa mfundo za Quad.
3Dziwani kuti mphamvu yowunikira yolowera sikutanthauza mphamvu yowunikira pamalo osankhidwa a bias. Ndi mphamvu yowunikira yayikulu kwambiri yomwe modulator ingatumize kwa wowongolera pamene bias voltage ikuchokera pa−Vπ ku +Vπ .
