• Umwirondoro muto: 40mm (W) × 28mm (D) × 8mm (H)
• Ihungabana ryinshi: gushyira mubikorwa byuzuye muburyo bworoshye Gukoresha:
• Gukoresha intoki hamwe na mini jumper Ibikorwa bya OEM binyuze muri UART2
• Uburyo bubiri bwo gutanga voltage kubogama: a.Ubugenzuzi bwa Bias Automatic b.Ukoresha asobanura bias voltage
Gusaba
• LiNbO3 hamwe nizindi IQmodulator
• QPSK, QAM, OFDM, SSB nibindi
• Ihererekanyabubasha

1. MER bivuga igipimo cyo kuzimya Modulator.Ikigereranyo cyo kuzimangana cyagezweho mubusanzwe igipimo cyo kuzimangana kwa modulator cyerekanwe muri datasheet ya modulator.
2. Nyamuneka menya ko imbaraga za optique zidahuye nimbaraga za optique kumwanya watoranijwe.Yerekeza ku mbaraga nini ya optique modulator ishobora kohereza mugenzuzi mugihe bias voltage iri hagati ya −Vπ kugeza + Vπ.

1 Inkingi iterwa na sisitemu ya RF.Iyo nta kimenyetso cya RF kiri muri sisitemu, inkingi igomba kuba nziza.Iyo ikimenyetso cya RF gifite amplitude irenze urwego runaka, inkingi izahinduka kuva muburyo bwiza.Muri iki gihe, Null point na Peak point bizahinduka hamwe.Q + point na Q- point bizahinduka hamwe kimwe.Polar switch ituma uyikoresha ahindura inkingi
mu buryo butaziguye udahinduye ingingo zikorwa.
