Ukusebenza
Umfanekiso 1. Ukucindezelwa Kwenkampani Yenethiwekhi
Umfanekiso 2. I-Pulse Generation
Umfanekiso 3. Amandla aphezulu e-modulator
Umfanekiso 4. Amandla amancane emoduli
I-Maxim DC extinction ratio
Kulesi sivivinyo, awekho amasiginali e-RF asetshenziswe ohlelweni.I-Pure DC extinciton ikaliwe.
1. Umfanekiso wesi-5 ubonisa amandla okubona okukhiphayo kwemoduli, lapho imojuli ilawulwa endaweni Ephakeme.Ibonisa i-3.71dBm kumdwebo.
2. Umfanekiso wesi-6 ubonisa amandla okubona okukhiphayo kwemoduli, lapho imojuli ilawulwa endaweni ye-Null.Ibonisa -46.73dBm kumdwebo.Ekuhloleni kwangempela, inani liyahluka cishe -47dBm;futhi -46.73 yinani elizinzile.
3. Ngakho-ke, isilinganiso sokuqothulwa kwe-DC esizinzile singu-50.4dB.
Izidingo zesilinganiso sokuqothulwa okuphezulu
1. Imodeli yesistimu kufanele ibe nesilinganiso sokuqedwa esiphezulu.Isici semoduli yesistimu sinquma ukuthi isilinganiso esiphezulu sokuqothulwa singafinyelelwa.
2. Ukuhlukaniswa kwe-polarization yokukhanya kwemoduli kuzonakekelwa.Ama-modulators ayazwela ku-polarization.I-polarization efanele ingathuthukisa isilinganiso sokuqothulwa ngaphezu kuka-10dB.Ekuhlolweni kwelebhu, ngokuvamile isilawuli se-polarization siyadingeka.
3. Izilawuli zokuchema ezifanele.Esivivinyweni sethu sesilinganiso sokuqothulwa kwe-DC, isilinganiso sokuqothulwa esingu-50.4dB sifinyelelwe.Ngenkathi imininingwane yomshini wokulinganisa yenza uhlu lwama-40dB kuphela.Isizathu salokhu kuthuthukiswa ukuthi amanye ama-modulators akhukhuleka ngokushesha okukhulu.I-Rofea R-BC-NOMA iziphi izilawuli zokuchema zibuyekeza i-voltage echema njalo ngomzuzwana ongu-1 ukuze ziqinisekise ukusabela kwethrekhi esheshayo.

1. Amanye amamoduli e-MZ anama-photodiode angaphakathi.Ukusethwa kwesilawuli kufanele kukhethwe phakathi kokusebenzisa i-photodiode yesilawuli noma ukusebenzisa i-photodiode yangaphakathi yesilawuli.Kunconywa ukusebenzisa i-photodiode yesilawuli ekuhlolweni kweLebhu ngezizathu ezimbili.Okokuqala, i-photodiode yesilawuli iqinisekise ikhwalithi.Okwesibili, kulula ukulungisa ukukhanya kokufakwayo.Qaphela: Uma usebenzisa i-photodiode yangaphakathi yemoduli, sicela wenze isiqiniseko sokuthi ukuphuma kwe-photodiode kuhambisana ngokuqinile namandla okufaka.
2. Iphinikhodi ye-Polar isetshenziselwa ukushintsha indawo yokulawula phakathi kwe-Peak ne-Null kumodi yokulawula i-Null (inqunywa iphinikhodi ye-Mode Select) noma i-Quad+
kanye nemodi yokulawula ye-Quad-in.Uma i-jumper ye-polar pin ingafakwanga, indawo yokulawula izoba Null kumodi ye-Null noma i-Quad+ kumodi ye-Quad.I-amplitude yesistimu ye-RF izophinde ithinte indawo yokulawula.Uma ingekho isignali ye-RF noma ubude besignali ye-RF buncane, isilawuli siyakwazi ukukhiya indawo yokusebenza ukuze ilungise iphuzu njengoba kukhethwe i-MS ne-PLR jumper.Lapho i-amplitude yesignali ye-RF idlula umkhawulo othile, i-polar yesistimu izoshintshwa, kulokhu, unhlokweni we-PLR kufanele ube esimweni esiphambene, okungukuthi i-jumper kufanele ifakwe uma ingakhishwanga noma ikhishwe uma ifakiwe.
Uhlelo lokusebenza olujwayelekile
