Ob qho tib si fiber ntau thiab dual fiber optical modules tuaj yeem xa thiab tau txais.Txij li ob txoj kev sib txuas lus yuav tsum muaj peev xwm xa thiab tau txais.Qhov txawv yog tias ib qho fiber ntau optical module tsuas muaj ib qho chaw nres nkoj xwb.Wavelength division multiplexing (WDM) thev naus laus zis yog siv los ua ke sib txawv tau txais thiab xa cov wavelengths mus rau hauv ib qho fiber ntau, lim los ntawm cov lim hauv qhov kho qhov muag module, thiab ib txhij ua tiav cov kev sib kis ntawm 1310nm optical signals thiab txais tos ntawm 1550nm optical signals, los yog vice versa. .Yog li ntawd, lub module yuav tsum tau siv nyob rau hauv khub (nws yog tsis yooj yim sua kom paub qhov txawv fiber ntau nrog tib transceiver wavelength).
Yog li ntawd, ib qho fiber ntau optical module muaj WDM ntaus ntawv, thiab tus nqi siab dua li ntawm dual fiber optical module.Txij li thaum lub dual fiber optical modules tau txais thiab tau txais ntawm cov chaw nres nkoj fiber ntau sib txawv, lawv tsis cuam tshuam rau ib leeg, thiab yog li tsis xav tau WDM, yog li cov wavelengths tuaj yeem ua tau zoo ib yam.Tus nqi yog pheej yig dua li ntawm ib qho fiber ntau, tab sis nws yuav tsum muaj fiber ntau ntau.
Ob chav fiber ntau optical module thiab ib qho fiber ntau optical module ua tau zoo ib yam, qhov sib txawv tsuas yog cov neeg siv khoom tuaj yeem xaiv ib qho fiber ntau lossis ob chav fiber ntau raws li lawv tus kheej xav tau.
Ib qho fiber ntau optical module yog kim dua, tab sis nws tuaj yeem txuag tau cov peev txheej fiber ntau, uas yog qhov kev xaiv zoo dua rau cov neeg siv khoom siv fiber ntau tsis txaus.
Lub dual fiber optical module kuj pheej yig, tab sis nws yuav tsum tau siv ib qho ntxiv fiber ntau.Yog tias cov khoom siv fiber ntau txaus, koj tuaj yeem xaiv lub dual fiber optical module.
