Ukusebenza
Umzobo 1. Ukunyanzeliswa kweCarrier
Umzobo 2. Isizukulwana sePulse
Umzobo 3. Imodyuli max amandla
Umzobo 4. Ubuncinci bamandla emodyuli
Umlinganiselo wokuphela kweMaxim DC
Kolu vavanyo, akukho miqondiso yeRF esetyenzisiweyo kwisistim. Ukutshatyalaliswa kwe-DC ecocekileyo kuye kwalinganiswa.
1. Umzobo we-5 ubonisa amandla okukhanya okuphuma kwemodyuli, xa imodyuli ilawulwa kwi-Peak point. Ibonisa i-3.71dBm kumzobo.
2. Umzobo we-6 ubonisa amandla okukhanya okukhutshwa kwemodyuli, xa imodyuli ilawulwa kwi-Null point. Ibonisa -46.73dBm kumzobo. Kuvavanyo lwangempela, ixabiso liyahluka malunga -47dBm; kwaye -46.73 lixabiso elizinzile.
3. Ngoko ke, umlinganiselo ozinzileyo we-DC wokutshabalala ulinganiswe yi-50.4dB.
Iimfuno zomlinganiselo ophezulu wokutshabalala
1. Imodyuli yesistim kufuneka ibe nomlinganiselo ophezulu wokutshabalala. Uphawu lwemodyuli yesixokelelwano lwenza isigqibo sokuba umlinganiselo ophezulu wokutshabalala unokufikelelwa.
2. Ipolarization yesibane sokufaka imodyuli iya kukhathalelwa. Iimodyuli zinovakalelo kwi-polarization. I-polarization efanelekileyo inokuphucula umlinganiselo wokutshabalala ngaphezu kwe-10dB. Kwimifuniselo yelebhu, ngokuqhelekileyo kufuneka isilawuli se-polarization.
3. Abalawuli be-bias abafanelekileyo. Kuvavanyo lwethu lwe-DC extinction ratio, umlinganiselo wokuphela kwe-50.4dB uphunyeziwe. Ngelixa idatabase yemodyuli yenza uluhlu lwe-40dB kuphela. Isizathu solu phuculo kukuba ezinye iimodyuli zihamba ngokukhawuleza kakhulu. I-Rofea R-BC-NAYIPHI na abalawuli be-bias bahlaziya i-voltage ye-bias rhoqo ngomzuzwana we-1 ukuqinisekisa ukuphendula ngokukhawuleza.

1. I-MER ibhekisa kwi-Modulator Extinction Ratio. Umlinganiselo wokutshabalala ophunyeziweyo uqhelekile ngumlinganiselo wokuphela kwemodyuli echazwe kwidatha yemodyuli.
2. I-CSO ibhekisa kulandelelwano lwesibini oluhlanganisiweyo. Ukulinganisa i-CSO ngokuchanekileyo, umgangatho womgca wesignali yeRF, iimodyuli kunye nabamkeli baya kuqinisekiswa. Ukongeza, ufundo lweCSO lwesixokelelwano lunokwahluka xa lusebenza kwiifrikhwensi ezahlukeneyo zeRF.
3. Nceda uqaphele ukuba i-input optical power ayihambelani namandla okukhanya kwindawo ekhethiweyo ye-bias point. Ibhekisa kumandla okukhanya aphezulu anokuthi imodyuli iwathumele kwisilawuli xa amandla ombane acalanye asuka ku- −Vπ ukuya ku +Vπ.

1. Ezinye iimodyuli ze-MZ zineefotodiodes zangaphakathi. Ukuseta isilawuli kufuneka kukhethwe phakathi kokusebenzisa ifotodiode yomlawuli okanye ukusebenzisa imodyuli yangaphakathi yeefotodiodi. Kuyacetyiswa ukuba usebenzise ifotodiode yomlawuli kwimifuniselo yeLab ngezizathu ezibini. Okokuqala, isilawuli se-photodiode siqinisekise umgangatho. Okwesibini, kulula ukulungelelanisa ukukhanya kokufakwayo. Qaphela: Ukuba usebenzisa i-photodiode yemodyuli yangaphakathi, nceda uqiniseke ukuba imveliso yangoku yefotodiode ilingana ngokungqongqo namandla egalelo.
2. I-polar pin isetyenziselwa ukutshintsha indawo yokulawula phakathi kwe-Peak kunye ne-Null kwimodi yokulawula i-Null (inqunywe yi-Mode Khetha iphini) okanye i-Quad+
kunye ne-Quad-kwimo yokulawula ye-Quad. Ukuba i-jumper ye-polar pin ayifakwanga, indawo yokulawula iya kuba yi-Null kwimodi ye-Null okanye i-Quad + kwimodi ye-Quad. Ubungakanani benkqubo yeRF nayo iya kuchaphazela indawo yolawulo. Xa kungekho signali yeRF okanye isandi somqondiso weRF sincinci, umlawuli uyakwazi ukutshixa indawo yokusebenza ukuze alungise indawo njengoko kukhethwe nguMS kunye nePLR jumper. Xa i-amplitude ye-RF yomqondiso idlula umqobo othile, i-polar yesixokelelwano iya kutshintshwa, kule meko, i-header ye-PLR kufuneka ibe kwindawo echaseneyo, oko kukuthi, i-jumper kufuneka ifakwe ukuba ayifakwanga okanye ikhutshwe ukuba ifakiwe.
