1. MER bivuga igipimo cyo kuzimangana kwa Modulator. Ikigereranyo cyo kuzimangana cyagezweho mubusanzwe igipimo cyo kuzimangana cya modulator cyerekanwe muri moderi ya datasheet.
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.
2Ihitamo rimwe gusa niryo rizahitamo hagati yo gukoresha fotodi ya mugenzuzi cyangwa gukoresha moderi ya moderi. Birasabwa gukoresha umugenzuzi Photodiode kubushakashatsi bwa Laboratwari kubwimpamvu ebyiri. Ubwa mbere, umugenzuzi Photodiode yemeje imico. Icya kabiri, biroroshye guhindura urumuri rwinjiza.Niba ukoresheje moderi yimbere ya moderi, nyamuneka urebe neza ko ibyasohotse muri fotodiode bihwanye cyane nimbaraga zo kwinjiza.
Rofea Optoelectronics itanga umurongo wibicuruzwa bya moderi yubucuruzi ya Electro-optique, Moderi ya Phase, Modulator, Intoderi, Photodetector, Laser yumucyo, laseri ya DFB, Optical amplifiers, EDFA, SLD laser, QPSK modulation, Pulse laser, Light detector, Photodetector, Laser shoferi . Dutanga kandi modulatrice yihariye yo kwihitiramo, nka 1 * 4 icyiciro cya moderi moderi, ultra-low Vpi, hamwe na moderi ya ultra-high extinction ratio modulator, ikoreshwa cyane cyane muri kaminuza n'ibigo.
Twizere ko ibicuruzwa byacu bizagufasha kubushakashatsi bwawe.
