1. E tohu ana te MER ki te Modulator Extinction Ratio. Ko te ōwehenga mate kua tutuki ko te ōwehenga ngaro o te kaiwhakaraupapa kua tohua i roto i te papaaarangi korero.
2. Kia mahara ko te mana whatu whakaurunga kaore e rite ki te mana whatu i te waahi whiriarua kua tohua. E tohu ana ki te mana whatu morahi ka taea e te kaihurihuri te kaweake ki te kaitahuri ina awhe ngaohiko rītaha mai i −Vπ ki +Vπ .

1 Ko te Polar e whakawhirinaki ana ki te tohu RF punaha. Mena kaore he tohu RF i roto i te punaha, me pai te polar. Ka nui ake te kaha o te tohu RF i tetahi taumata, ka huri te polar mai i te pai ki te kino. I tenei wa, ka huri te tohu Null me te Peak point tetahi ki tetahi. Ko te tohu Q+ me te tohu-Q ka huri ano tetahi ki tetahi. Ko te huringa polar ka taea e te kaiwhakamahi te huri i te polar
tika me te kore e huri i nga tohu mahi.
2Kia kotahi anake te kowhiringa i waenga i te whakamahi photodiode kaiwhakahaere me te whakamahi photodiode modulator ranei. E taunaki ana kia whakamahia te photodiode kaiwhakahaere mo nga whakamatautau Lab mo nga take e rua. Tuatahi, kua whakapumauhia e te photodiode kaiwhakahaere nga kounga. Tuarua, he maamaa ake te whakatika i te kaha o te rama whakauru.Mehemea kei te whakamahi i te photodiode o roto o te modulator, me mohio kei te tino rite te putanga o te photodiode ki te mana whakauru.
Ko te Rofea Optoelectronics e tuku ana i te raina hua o nga miihini Electro-optic arumoni, Kaihuri i te Waahanga, Kaihurihuri Intensity, Photodetectors, Mataiti rama Taiaho, lasers DFB, Amplifiers Optical, EDFA, SLD laser, QPSK modulation, Pulse laser, Maama marama, Kaitirotiro taurite, taraiwa Taiaho , Whakanuia te muka, Te mita hiko orotika, te taiaho whanui, te taiaho Tunable, te kaitirotiro orotika, te taraiwa taiaho diode, te whakakaha muka. Ka whakaratohia ano e matou he maha nga momo whakarereke mo te whakarite, penei i te 1 * 4 nga waahanga whakahurihuri, te Vpi iti-iti, me nga kaiwhakaritenga owehenga ohanga tino teitei, e whakamahia ana i nga whare wananga me nga whare wananga.
Ko te tumanako ka awhina a maatau hua ki a koe me to rangahau.
