Panui:
1 * Ko te korero ki te whakauru kaha ki te waahanga ka nui te nui o te putanga Modulator. Mo te mana iti o te modulator me te paanga nui rawa atu, me nui te piki haere o te mana whakauru; Ma nga whakaritenga whakauru mana motuhake, ka taea e koe te whakatika i nga tohu o te hoa rangatira me te kaihōpara e tohu ana, me toro atu ki nga hoko i te wa e tuku ana i nga ota.
2 * Ina whakatakotoria he ota, tohua te roanga mahi, me whakarite kia rite ki te roa o te mahi.
3 * Ko te hurihuri i te reanga ngaro ka whakawhirinaki hoki ki te huri i te taumata reanga o te modulator ake.

1 Ko te polar e whakawhirinaki ana ki te tohu RF. Mena kaore he tohu RF i roto i te punaha, me whai hua te polar. I te wa e nui ake ana te tohu RF i tetahi taumata, ka huri te polar mai i te pai ki te kino. I tenei wa, ka huri a Null Point me te Point Point me tetahi ki tetahi.Q
tika me te kore e whakarereke i nga tohu whakahaere.
2Kotahi noa iho te whiringa ka tohua i waenga i te whakaahua kaiwhakahaere, ma te whakamahi i te kaiwhakaari modulator ranei. E taunaki ana kia whakamahia te whakaahua kaiwhakahaere mo nga whakamatautau taiwhanga mo nga take e rua. Tuatahi, kua whakatauhia e te Kaimanaaki te kounga o te Kaituku. Tuarua, he ngawari ake te whakatika i te kaha o te whakaheke i te kaha o te kaiwhakamahara o te modulator.
Ko Rofea Optoelectronics te raina hua o nga kaiwhakaora-arotau, nga kaiwhakaari kaha, nga whakaahua a laser, te miihini optical. laser, te laser laser, te kaimau optical, te taraiwa laser diode, ka whakanuia te muka. Ka whakaratohia ano hoki e matou etahi atu modulate motuhake mo te whakarite, penei i te 1 * 4 Whakapaipai i nga kaiwhakatakoto tohu, me te miihini nui o te ultra-teitei, me te whare wananga.
Ko te tumanako ka awhina a maatau hua ki a koe me o mahi rangahau.
