Tuhipoka:
Ko te 1* e pā ana ki te whānuitanga mana e whakauru ana ki te kōwae ina teitei rawa te putanga o te modulator. Mō te mana whakahaere iti o te modulator me te ōwehenga mate nui, me whakanui ake te mana whakauru; Me ngā whakaritenga whakauru mana motuhake, ka taea e koe te whakatika i te hononga ā-roto me ngā tohu whakanui pūoko, tēnā tirohia ngā kaihoko ina tuku ota ana.
2* I te wā e tuku ana i tētahi ota, tohua mai te roangaru mahi, me arotau kia rite ki te roangaru mahi.
Ko te ōwehenga whakamomori whakawhiti 3* ka whakawhirinaki anō ki te taumata ōwehenga whakamomori whakawhiti o te modulator tonu.

1 Ka whakawhirinaki te pōra ki te tohu RF o te pūnaha. Mēnā kāore he tohu RF i roto i te pūnaha, me pai te pōra. Mēnā he nui ake te kaha o te tohu RF i tētahi taumata, ka huri te pōra mai i te pai ki te kino. I tēnei wā, ka huri te pūwāhi kore me te pūwāhi tihi tetahi ki tetahi. Ka huri hoki te pūwāhi Q+ me te pūwāhi Q- tetahi ki tetahi. Mā te pana pōra ka taea e te kaiwhakamahi te huri i te pōra
tika me te kore e whakarerekē i ngā pūwāhi mahi.
2Kotahi anake te kōwhiringa hei whiriwhiri i waenga i te whakamahi i te photodiode kaiwhakahaere, te whakamahi rānei i te photodiode modulator. E rua ngā take e taunakihia ana kia whakamahia te photodiode kaiwhakahaere mō ngā whakamātautau taiwhanga. Tuatahi, he pai ngā kounga o te photodiode kaiwhakahaere. Tuarua, he māmā ake te whakarite i te kaha o te mārama whakauru. Mena kei te whakamahi koe i te photodiode ā-roto o te modulator, me whakarite kia rite te iahiko putanga o te photodiode ki te mana whakauru.
Kei a Rofea Optoelectronics he raina hua o ngā whakarerekētanga hiko-whatu arumoni, ngā whakarerekētanga ā-wāhanga, ngā whakarerekētanga kaha, ngā kite whakaahua, ngā pūtake mārama taiaho, ngā taiaho DFB, ngā whakakaha whatu, EDFA, taiaho SLD, te whakarerekētanga QPSK, te taiaho pātere, te kite mārama, te kite whakaahua taurite, te taraiwa taiaho, te whakakaha muka whatu, te mita mana whatu, te taiaho whānui, te taiaho ka taea te whakarerekē, te kite whatu, te taraiwa taiaho diode, te whakakaha muka. E whakarato ana hoki mātou i te maha o ngā whakarerekētanga motuhake hei whakaritenga, pērā i ngā whakarerekētanga ā-wāhanga 1*4, te Vpi tino iti, me ngā whakarerekētanga ōwehenga whakamōmona tino teitei, e whakamahia ana i ngā whare wānanga me ngā whare wānanga.
