Ultra Compact DP-IQ Modulator Bias Igenzura Automatic Bias Igenzura
Ikiranga
• Icyarimwe gitanga amashanyarazi atandatu yo kubogama ya Dual Polarisation IQ modulator
Imiterere yo kwigana yigenga:
SSB, QPSK, QAM, OFDM yagenzuwe.
Gucomeka no gukina:
Nta kalibasi yintoki ikenewe Byose byikora
• I, Q intwaro: kugenzura kuri Peak na Null modes Ikigereranyo cyo kuzimangana: 50dB max1
• P ukuboko: kugenzura kuri Q + na Q- uburyo Bwuzuye: ± 2◦
• Umwirondoro muto: 40mm (W) × 29mm (D) × 8mm (H)
• Ihungabana ryinshi: gushyira mubikorwa byuzuye muburyo bworoshye Gukoresha:
• Gukoresha intoki hamwe na mini jumper 2
Ibikorwa bya OEM byoroshye binyuze muri UART / IO
• Uburyo bubiri bwo gutanga voltage kubogama: a.Ubugenzuzi bwa Bias Automatic b.Ukoresha asobanura bias voltage
Gusaba
• LiNbO3 hamwe nabandi ba moderi ba DP-IQ
• Ihererekanyabubasha
1Umubare munini wo kuzimangana biterwa kandi ntushobora kurenga 1 sisitemu modulator ntarengwa yo kuzimangana.
2Igikorwa cya UART kirashoboka gusa kuri verisiyo imwe ya mugenzuzi.
Imikorere
Igishushanyo 1. Inyenyeri (idafite umugenzuzi)
Igishushanyo 2. QPSK Inyenyeri (hamwe na mugenzuzi
Igicapo 3. Uburyo bwa QPSK-Ijisho
Igicapo 5. 16-QAM Uburyo bwinyenyeri
Igicapo 4. Ikirangantego cya QPSK
Igicapo 6. CS-SSB Ikirangantego

1 MER bivuga igipimo cya Modulator yo kuzimangana.Ikigereranyo cyo kuzimangana cyagezweho mubisanzwe igipimo cyo kuzimangana cya modulator cyerekanwe muri moderi ya datasheet.
2RekaVπ kwerekana voltage ibogamye kuri 180◦ naVP vuga cyane cyane bias voltage kuri Quad point.
3Nyamuneka menya ko kwinjiza optique imbaraga zidasobanura imbaraga za optique kumwanya watoranijwe.Nimbaraga ntarengwa optique modulator ishobora kohereza mugenzuzi mugihe bias voltage itandukanijwe-Vπ Kuri +Vπ .
