OTU yog qhov luv ntawm kho qhov muag pom ntawm Lub Hauv Paus, uas yog pawg tswj hwm nyob rau hauv cov khoom siv hauv qhov kev faib ua ntu, thiab yog lub luag haujlwm rau kev nkag mus ntawm cov cim kho qhov muag.
Txoj kev hloov kho hluav taws xob-kho qhov muag siv hluav taws xob tau siv los ua kom tiav qhov hloov ntawm qhov yoj yuag.
Ua ntej tshaj, lub teeb liab hluav taws xob tau txais los ntawm cov cuab yeej siv tau txais los ntawm tus neeg siv hluav taws xob kho qhov muag tau hloov mus rau lub teeb liab hluav taws xob, uas yog nthuav dav, duab / moos ua haujlwm tawm, thiab tom qab ntawd cov teeb liab hluav taws xob tau hloov mus rau lub laser Output.
Cov yam ntxwv ntawm OTU suav nrog:
1. Muab cov teeb tsa tus qauv thiab ruaj khov
Vim tias DWDM lub cev xav tau ntau yam kab ke sib txuas hauv qhov poob qis ntawm lub qhov rais qis thiab qhov ntev ntawm qhov yoj yoj me me, qhov nruab nrab ntawm qhov nruab nrab ntawm DWDM hom teeb ci xav tau los ua haujlwm tsis tu ncua ntawm cov nominal chaw zaus ua ntu zus los ntawm ITU-T tus qauv kev qhia tshwj xeeb.
2. Muab qhov khoom hluav taws xob nrog cov nqi hluav taws xob loj dua
Qhov nce ntawm qhov ntev ntawm cov tsis txuas hluav taws xob ntawm WDM qhov system yuav tsum muaj lub zog ua kom qhov kev sib cais tiv thaiv kev ncua deb ntawm lub teeb pom kev zoo thiab muaj peev xwm ua kom dhau qhov kev cuam tshuam ntawm cov kab hluav taws xob.
3. Siv raws li kev tsim dua tshiab
Thaum lub hloov dua siab tshiab siv los ua tus tsim tawm, nws muaj cov ntaub ntawv rov ua dua tshiab. Kev tsim cov ntaub ntawv rov qab yog kev xaiv ua haujlwm ntawm lub wavelength converter.
