Ultra Compact IQ Modulator Bias Igenzura Automatic Bias Igenzura

Ibisobanuro bigufi:

Rofea 'modulator kubogama yabugenewe yabugenewe kubushakashatsi bwa Mach- Zehnder kugirango barebe imikorere ihamye mubikorwa bitandukanye.Ukurikije uburyo bwuzuye bwuzuye bwo gutunganya ibimenyetso, umugenzuzi arashobora gutanga ultra ihamye imikorere.

Umugenzuzi atera inshuro nke, amplitude make yerekana ibimenyetso hamwe na bias voltage muri modulator.Ikomeza gusoma ibisohoka muri modulator ikanagena imiterere ya bias voltage hamwe nikosa rifitanye isano.Umuvuduko mushya wo kubogama uzakoreshwa nyuma yijambo ukurikije ibipimo byabanje.Muri ubu buryo, modulator yemerewe gukora munsi ya bias ikwiye.

Ikiranga

• Itanga kubogama kubintu bitatu bya modulator IQ modulisiyo yigenga:
• QPSK, QAM, OFDM, SSB yagenzuwe
Gucomeka no gukina:
Nta kalibasi yintoki ikenewe Byose byikora
• I, Q amaboko: 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) × 28mm (D) × 8mm (H)
• Ihungabana ryinshi: gushyira mubikorwa byuzuye muburyo bworoshye Gukoresha:
• Gukoresha intoki hamwe na mini jumper Ibikorwa bya OEM binyuze muri UART2
• Uburyo bubiri bwo gutanga voltage kubogama: a.Ubugenzuzi bwa Bias Automatic b.Ukoresha asobanura bias voltage
