Ultra Compact IQ Modulator Bias Controller Atomatik Bias Controller

Takaitaccen Bayani:

Rofea' modulator mai kula da son rai an ƙera shi ne musamman don masu daidaitawa na Mach-Zehnder don tabbatar da ingantaccen yanayin aiki a wurare daban-daban na aiki.Dangane da cikakkiyar hanyar sarrafa siginar sa, mai sarrafawa na iya samar da ingantaccen aiki.

Mai sarrafawa yana allurar ƙaramin mitar siginar ƙaramar sigina tare da ƙarancin ƙarfin lantarki a cikin na'urar.Yana ci gaba da karanta abubuwan da aka fitar daga mai daidaitawa kuma yana ƙayyade yanayin ƙarfin wutar lantarki da kuskuren da ke da alaƙa.Za a yi amfani da sabon ƙarfin wuta na son zuciya bayan kalmomi bisa ga ma'aunin baya.Ta wannan hanyar, ana tabbatar da modulator yayi aiki a ƙarƙashin ingantacciyar wutar lantarki.
