Optical module yog ib qho tseem ceeb hauv kev sib txuas lus fiber ntau optical, lub luag haujlwm rau kev hloov kho qhov muag-hluav taws xob thiab hluav taws xob-kho qhov muag hloov dua siab tshiab. Feem ntau, nws muaj optical transmitter Cheebtsam (TOSA, nrog rau lasers), optical receiver Cheebtsam (ROSA, nrog rau photodetectors), functional circuits, thiab optical (hluav taws xob) interfaces. Ib qho khoom siv kho qhov muag, tseem hu ua optical transceiver lossis fiber optic module, yog ib qho kev cog lus, nws tus kheej muaj cov cuab yeej siv hauv fiber ntau optic kev sib txuas lus los xa thiab tau txais cov teeb liab kho qhov muag. Cov modules no feem ntau muaj xws li ib tug transmitter, ib tug receiver, thiab cov khoom siv hluav taws xob txuam nrog nyob rau hauv ib lub tsev.
Lub transmitter ib feem ntawm lub module hloov hluav taws xob teeb liab mus rau hauv optical signals, feem ntau yog siv lub laser diode los yog lub teeb-emitting diode (LED). Cov teeb liab kho qhov muag no ces kis tau los ntawm ib qho fiber ntau optical. Ntawm qhov kawg tau txais, cov teeb liab kho qhov muag tau txais los ntawm photodetector, uas hloov lawv rov qab rau hauv hluav taws xob teeb liab rau kev ua haujlwm ntxiv los ntawm cov khoom tau txais.
Optical modules tuaj nyob rau hauv ntau yam txheej txheem thiab interface hom kom haum raws li cov qauv kev sib txuas lus thiab network architectures. Cov hom kev sib txuas feem ntau suav nrog Daim Ntawv Me-yam Pluggable (SFP), QSFP (Quad Small Form-factor Pluggable), CFP (C Form-factor Pluggable), thiab SFP28 (Small Form-factor Pluggable 28). Cov qauv no txhawb nqa cov ntaub ntawv sib txawv xws li tus qauv gigabit Ethernet mus rau kev sib txuas ultra-high-speed xws li 100 gigabits ib ob (Gbps) lossis siab dua.
Optical modules ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev kub ceev, nyob deb ntawm cov ntaub ntawv xa mus rau hauv kev sib txuas lus hauv xov tooj, cov chaw khaws ntaub ntawv, thiab lwm qhov chaw ua haujlwm siab. Lawv qhov loj me, kev ntseeg siab, thiab kev sib tshuam ua rau lawv cov khoom tseem ceeb hauv kev sib txuas lus kho qhov muag niaj hnub. Tsis tas li ntawd, kev nce qib hauv kev siv tshuab kho qhov muag txuas ntxiv mus rau kev txhim kho cov ntaub ntawv xa mus ceev, muaj peev xwm, thiab ua haujlwm tau zoo, ntxiv rau kev hloov pauv ntawm kev sib txuas lus fiber ntau.
Optical modules feem ntau yog siv rau hauv peb qhov xwm txheej loj: kev sib txuas lus hauv xov tooj cua, kev nkag mus rau hauv tes hauj lwm, cov chaw zov me nyuam, thiab Ethernet. Telecommunications backbone tes hauj lwm thiab kev siv tes hauj lwm muaj nyob rau hauv kev lag luam kev lag luam. Ntawm lawv, wavelength division multiplexing (xWDM) optical modules feem ntau yog siv nyob rau hauv nruab nrab thiab ntev-ntev kev sib txuas lus qaum tes hauj lwm. Optical interconnects feem ntau yog siv rau qhov ntev-ntev, muaj peev xwm kis tau tus mob hauv cov tub ntxhais ntawm cov pob txha caj qaum. Kev lag luam nkag mus rau hauv lub network sawv cev rau " mais kawg" los ntawm cov tswv lag luam rau cov neeg siv, suav nrog cov xwm txheej xws li fiber-to-the-home passive optical networks (FTTH PON) thiab daim ntawv thov wireless pem hauv ntej. Cov chaw zov me nyuam cov ntaub ntawv thiab Ethernet kev lag luam feem ntau suav nrog cov xwm txheej xws li cov ntaub ntawv hauv chaw sib cuam tshuam, cov ntaub ntawv chaw sib cuam tshuam (DCI), thiab kev lag luam Ethernet.
