Txhua tus thib ob, tub rog lub chaw ua tub rog kev tshaj tawm txoj haujlwm - Qhov kev sib ntaus sib tua fiber ntau thaum ub no {}}} Tsis muaj teeb meem poob, tsis muaj bandwidth kev cuam tshuam. Cov ntaub ntawv chaw tuav cov petabytes ntawm cov tsheb khiav ob qho kev qhia los ntawm tib lub tsev. Kev siv network ua ke ntau txhiab tus ntawm sensors thiab cov neeg ua yeeb yam hauv tiag {}} lub sij hawm bidirectional sib pauv. Cov xwm txheej no faib tawm txoj kev yuav tsum tau ua: transceer xa thiab tau txais cov haujlwm Bidirectional thiab txais tos. Qhov no ob ua haujlwm sib luag no sawv cev ntau dua qhov yooj yim {}}} Nws txhais tau cov khoom siv sib txuas lus niaj hnub no.
Vim li cas txoj kev pab me me defines niaj hnub transceivers
Ib transceer sib txuas ua ke ntawm lub transmitter thiab txais hauv ib chav tsev, ua kom sib txuas lus bidirectional, tab sis qhov kev sib xyaw ua ke no ua rau muaj kev sib xyaw ua ke. Kev twv txiaj ntawm Bidirecture Chaw Nyob peb txoj kev muaj kev sib tw hauv cov tshuab sib txuas lus: Spectrum efficiency, infrastrastructure siv, thiab ua haujlwm hloov pauv.
Kev hloov pauv Bidi siv wavelength divisth multiplexing (WDM) cais cov cim nce toj thiab {}} cov ntaub ntawv rho tawm dua ib fiber. For transceiver send and receive functions to operate simultaneously, the system must implement sophisticated wavelength separation-typically at 1310nm/1490nm or 1270nm/1330nm pairs. Qhov no muaj txiaj ntsig ob zaug muaj peev xwm ntxiv lub cev muaj cuab yeej siv ntxiv uas tsis muaj neeg nyob thoob ntiaj teb chaw lossis cov vaj tse sib txawv uas muaj fiber ntau.
Qhov yuav tsum tau rau Bidirectional muaj peev xwm bidirectable stems los ntawm cov asymmetric xwm ntawm cov ntaub ntawv niaj hnub ntws. Network cov qauv tsheb khiav tsis tshua pom zoo sib npaug; Kev noj khoom haus qis dua ib yam nkaus tshaj li nce toj hauv cov neeg siv khoom ib puag ncig, thaum chaw lag luam network ua rau muaj kev faib tawm. Nkag siab tias TransceIer xa tau li cas thiab tau txais kev tswj hwm ua ke ua haujlwm tseem ceeb ua rau kev ua kom zoo rau cov qauv asymmetric. Tag nrho - kev ua haujlwm duplex tso cai rau kev sib txuas lus hauv ob qho tib si-}}} tuaj yeem xa ib lub sijhawm.
Kev tshawb fawb los ntawm MIT lub khw muag khoom sib txuas lus pom tau tias muaj kev sib txuas lus ob npaug rau ib nrab- duplex tshuab. Kev siv cov tswv yim yuav tsum tau sophisticated tus kheej {}} kev cuam tshuam ntau tshaj li tau txais lub teeb liab los ntawm 100 db lossis ntau dua.

Pillar 1: Wavelength Division Conchecture Architecture
Bidi SFP Transce Siv WDM los xa cov ntaub ntawv ntawm kev kho qhov muag txawv txawv ntawm kev kho qhov muag, tso cai rau ob {}} txoj kev sib txuas lus. Tus txheej txheem nyob ntawm seb puas yuav cais tawm wavelength sib cais-}}} {}} hom fiber ntau cov ntaub ntawv fiber ntau. Thaum Transceiver xa thiab tau txais wavelengths khiav ntawm cov sib txawv ntawm cov kab sib txawv, cov tsheb ciav hlau qis thiab teeb liab kev ncaj ncees nyob hauv siab tshaj plaws.
Wdm Coupler ua haujlwm ua qhov tseem ceeb tiv thaiv uas ua rau kev sib cais no. Ib qho kev sib xyaw WDM coupler lossis lim lub teeb pom kev sib txawv nrog kev sib tw sib txawv hauv ib qho kev sib txawv kom ua rau ib txhij sib kis bidirectional. Qhov kev siv kho qhov muag no sib xyaw ua ke ntawm cov wavelengths rau hauv ib qho fiber ntau strand, ces cov neeg ua yeeb yam ntawm lawv tus txais nyiaj tsis muaj crosstalk lossis cuam tshuam nrog kev sib cuam tshuam lossis cuam tshuam nrog kev cuam tshuam nrog kev sib cuam tshuam.
Kev xa tawm kom muaj kev sib deev. Txhua tus Bidi Transceal siv ib lub nthwv dej tshwj xeeb rau kis thiab lwm tus kom tau txais. Piv txwv li, bidi - m mchm yuav tsum tau khub nrog bidi {} b module siv 1550nm rau kis. Yog hais tias nthwv wavelengths tsis phim, qhov txuas yuav swb. Qhov kev txwv no tsim nyog ua kom tau txais kev ua haujlwm thiab kev teeb tsa kev teeb tsa, tshwj xeeb hauv cov khoom siv uas tsis muaj peev xwm cuam tshuam rau txhua ntu.
Kev siv lub cev ua haujlwm tshwj xeeb kho qhov muag. Ib lub laser diode (DFB lossis EML) emits teeb ntawm ib lub nthwv dej rau kis tau tus mob, PIN lossis APD) ntes tau rov qab cov cim hluav taws xob. Cov feem no yuav tsum ua haujlwm tsis pub dhau kev zam lub cim qhia kev ncaj ncees thoob plaws ib puag ncig.
