Ukusebenza
Umfanekiso 1. Ukucindezela Komthwali
Umfanekiso 2. Ukukhiqizwa Kwe-Pulse
Umfanekiso 3. Amandla aphezulu e-Modulator
Umfanekiso 4. Amandla amancane e-Modulator
Isilinganiso sokuphela kwe-Maxim DC
Kulolu vivinyo, awekho amasignali e-RF asetshenziswe ohlelweni. I-Pure DC extinciton ilinganisiwe.
1. Umfanekiso 5 ukhombisa amandla okukhanya okukhipha kwe-modulator, lapho i-modulator ilawulwa endaweni ye-Peak. Ibonisa i-3.71dBm kumdwebo.
2. Isithombe 6 sibonisa amandla okukhanya okukhipha kwe-modulator, lapho i-modulator ilawulwa endaweni ye-Null. Ibonisa -46.73dBm kumdwebo. Ekuhlolweni kwangempela, inani liyahlukahluka cishe -47dBm; futhi -46.73 iyinani elizinzile.
3. Ngakho-ke, isilinganiso sokuphela kwe-DC esizinzile esilinganisiwe singu-50.4dB.
Izidingo zesilinganiso esiphezulu sokuphela
1. I-modulator yesistimu kumele ibe nesilinganiso esiphezulu sokuphela. Isici se-modulator yesistimu sinquma ukuthi isilinganiso esiphezulu sokuphela singafinyelelwa.
2. Ukuhlukaniswa kokukhanya kokufaka kwe-modulator kufanele kunakekelwe. Ama-modulators azwela ukuhlukaniswa. Ukuhlukaniswa okufanele kungathuthukisa isilinganiso sokuphela kwe-extinction ngaphezu kwe-10dB. Ezivivinyweni zelebhu, ngokuvamile kudingeka isilawuli sokuhlukaniswa kwe-polar.
3. Abalawuli be-bias abafanele. Ekuhlolweni kwethu kwesilinganiso sokuphela kwe-DC, isilinganiso sokuphela kwe-50.4dB sifinyelelwe. Ngenkathi ishidi ledatha lomkhiqizi we-modulator libala kuphela i-40dB. Isizathu salokhu kuthuthuka ukuthi amanye ama-modulator ahamba ngokushesha kakhulu. Abalawuli be-bias be-Rofea R-BC-ANY babuyekeza i-voltage ye-bias njalo ngomzuzwana owodwa ukuqinisekisa impendulo esheshayo.

1. I-MER ibhekisela ku-Modulator Extinction Ratio. Isilinganiso sokuphela esifinyelelwayo ngokuvamile siyisilinganiso sokuphela kwe-modulator esichazwe kudatha ye-modulator.
2. I-CSO ibhekisela ku-composite second order. Ukuze kulinganiswe i-CSO ngendlela efanele, ikhwalithi eqondile yesignali ye-RF, ama-modulators kanye nama-receiver kufanele iqinisekiswe. Ngaphezu kwalokho, ukufundwa kwesistimu ye-CSO kungahluka uma kusebenza kumaza ahlukene e-RF.
3. Sicela uqaphele ukuthi amandla okukhanya okufakwayo awahambisani namandla okukhanya endaweni ekhethiwe ye-bias. Kubhekisela emandleni okukhanya aphezulu kakhulu i-modulator engawathumela kumlawuli lapho i-bias voltage isukela ku-−Vπ kuya ku-+Vπ.

1. Amanye ama-modulator e-MZ anama-photodiode angaphakathi. Ukusethwa kwesilawuli kufanele kukhethwe phakathi kokusebenzisa i-photodiode yesilawuli noma ukusebenzisa i-photodiode yangaphakathi ye-modulator. Kunconywa ukusebenzisa i-photodiode yesilawuli ekuhlolweni kwelebhu ngezizathu ezimbili. Okokuqala, i-photodiode yesilawuli iqinisekisile ikhwalithi. Okwesibili, kulula ukulungisa inhloso yokukhanya kokufaka. Qaphela: Uma usebenzisa i-photodiode yangaphakathi ye-modulator, sicela uqiniseke ukuthi ugesi wokukhipha we-photodiode ulingana ngokuphelele namandla okufaka.
2. Iphini eliyi-polar lisetshenziselwa ukushintsha indawo yokulawula phakathi kwe-Peak ne-Null kumodi yokulawula ye-Null (enqunywa yiphini le-Mode Select) noma i-Quad+
kanye nemodi yokulawula ye-Quad-in Quad. Uma i-jumper yephini le-polar ingafakwanga, indawo yokulawula izoba yi-Null kumodi ye-Null noma i-Quad+ kumodi ye-Quad. Ububanzi besistimu ye-RF buzothinta nephuzu lokulawula. Uma kungekho signali ye-RF noma i-amplitude yesignali ye-RF incane, isilawuli siyakwazi ukukhiya indawo yokusebenza ukuze iqonde iphuzu njengoba kukhethwe yi-MS kanye ne-PLR jumper. Lapho i-amplitude yesignali ye-RF idlula umkhawulo othile, i-polar yesistimu izoshintshwa, kulokhu, i-header ye-PLR kufanele ibe sesimweni esiphambene, okungukuthi i-jumper kufanele ifakwe uma ingafakwanga noma ikhishwe uma ifakiwe.
