Kev sib xyaw ua ke ntawm optical transceiver module yog tsim los ntawm cov khoom siv optoelectronic, kev ua haujlwm circuits thiab optical interfaces. Cov khoom siv optoelectronic suav nrog ob ntu: kis thiab txais. Kev sib xyaw ua ke ntawm optical transceiver module yog cov cuab yeej tseem ceeb ntawm kev sib txuas lus kho qhov muag, uas ua tiav qhov kev hloov kho qhov muag-hluav taws xob / hluav taws xob-kho qhov muag hloov pauv ntawm cov teeb liab kho qhov muag. Nws muaj ob ntu: qhov tau txais thiab qhov xa tawm. Qhov tau txais ib feem paub txog kev hloov dua siab tshiab-hluav taws xob, thiab qhov kev xa tawm paub txog kev hloov pauv hluav taws xob-optic.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog dab tsiBIDIIb qho fiber ntau bidirectional optical module? BIDI ib leeg-fiber bidirectional kho qhov muag module yuav tsum xa thiab tau txais cov teeb liab kho qhov muag nyob rau hauv ob qho kev qhia tib lub sijhawm. Nws yuav tsum siv qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov kev xa thiab tau txais cov lus qhia, tab sis tsuas muaj ib qho chaw nres nkoj xwb, uas yog lim los ntawm cov lim dej hauv qhov kho qhov muag module, thiab kev sib kis ntawm ib lub wavelength optical teeb liab ua tiav tib lub sijhawm. thiab txais cov teeb liab kho qhov muag ntawm lwm lub wavelength, los yog vice versa. Piv txwv li, qhov kawg hauv zos xa cov teeb liab kho qhov muag ntawm 1310 nm thiab tau txais cov teeb liab kho qhov muag ntawm1550nm tib lub sijhawm. Lub wavelength siv los ntawm cov phooj ywg kawg yog qhov sib txawv ntawm qhov kawg hauv zos, uas yog, nws xa cov teeb liab kho qhov muag ntawm 1550 nm thiab tau txais cov teeb liab kho qhov muag ntawm 1310 nm.
Yog li ntawd, lub module yuav tsum tau siv nyob rau hauv khub ntawm ob kawg ntawm qhov txuas. Feem ntau siv wavelengths ntawm ib leeg-fiber bidirectional optical modules yog 1310 nm / 1490 nm, 1510 nm / 1590 nm unidirectional bidirectional transceiver Cheebtsam yog MQW-TO-LD lub teeb qhov chaw, TO-PIN-TIA (transimpedance amplifier) detector, beam splitter, optical fiber ntau thiab lwm yam khoom yog tag nrho cov kev sib txuas thiab sib sau ua ke los ntawm coaxial coupling txheej txheem. Ib leeg-fiber bidirectional yog ib qho cuab yeej siv BOSA cov khoom kom ua tiav kev sib txuas lus sib txuas.
Ntawd yog, hom module no sib txuas ua haujlwm tau txais thiab xa ua haujlwm kom paub txog ob txoj kev sib kis. Vim li cas thiaj xaiv BiDi optical module? Qhov zoo tshaj plaws ntawm BiDi optical modules, xws li SFP ntxiv rau BiDi optical modules lossis SFP BiDi optical modules, yog tias nws tuaj yeem txo tus naj npawb ntawm cov chaw nres nkoj ntawm optical fiber thaj qaum vaj huam sib luag, txuag tus nqi ntawm optical fiber ntau cabling infrastructure, thiab muaj peev xwm kuj txo qhov chaw thaiv, uas pab tswj cov fiber ntau thiab txo cov fibers uas yuav tsum tau muaj. Tus nqi ntawm BiDi optical modules (WDM optical modules) yog siab dua li ntawm cov tsoos dual-fiber bidirectional optical modules, tab sis tus naj npawb ntawm cov fibers optical xav tau los ntawm BiDi optical modules ib chav tsev kis tau tus mob yog txo los ntawm ib nrab.
Rau ntau cov kab sib txuas, kev txuag nqi ntawm kev siv cov fibers tsawg dua nyob deb tshaj tus nqi ntawm kev yuav BiDi optical modules. BiDi ib leeg-fiber bidirectional optical modules siv nyob qhov twg? Ib leeg-fiber bidirectional feem ntau yog siv rau cov neeg siv nkag mus rau network kom tiav cov duab, cov ntaub ntawv, suab thiab lwm yam kev sib txuas lus ntawm tus nqi qis.
