Cov modules optical yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv sib txuas lus optical thiab cov channel sib txuas ntawm lub ntiaj teb optical thiab lub ntiaj teb hluav taws xob.
1. Ua ntej tshaj plaws, lub optical module yog ib lub cuab yeej optoelectronic uas ua qhov kev hloov pauv photoelectric thiab electro-optical. Lub optical module tseem hu ua fiber optic transceiver, uas feem ntau yog siv rau kev hloov pauv photoelectric ntawm cov teeb liab. Nws hloov cov teeb liab hluav taws xob ntawm lub cuab yeej mus rau hauv lub teeb liab optical ntawm qhov kawg xa, thiab rov qab kho cov teeb liab optical mus rau hauv lub teeb liab hluav taws xob ntawm qhov kawg txais. Lub optical module yog tsim los ntawm lub transmitter laser, lub receiver detector, thiab cov khoom siv hluav taws xob rau cov ntaub ntawv encoding / decoding.
2. Tom qab ntawd cov khoom siv sib txuas lus yog cov khoom siv sib txuas lus wired thiab cov khoom siv sib txuas lus wireless rau kev tswj hwm kev lag luam. Kev sib txuas lus wired txhais tau tias cov khoom siv sib txuas lus yuav tsum tau txuas nrog cables, uas yog, siv cov cables overhead, coaxial cables, optical fibers, audio cables thiab lwm yam xov xwm xa xov xwm. Kev sib txuas lus wireless txhais tau tias kev sib txuas lus uas tsis xav tau cov kab sib txuas lub cev, uas yog, txoj kev sib txuas lus uas siv cov yam ntxwv uas cov teeb liab electromagnetic tuaj yeem kis mus rau hauv qhov chaw dawb rau kev sib pauv xov xwm.
3. Thaum kawg, cov khoom siv hluav taws xob yog cov khoom siv ntawm cov khoom siv hluav taws xob thiab cov tshuab me me thiab cov cuab yeej. Keeb kwm kev loj hlob ntawm cov khoom siv hluav taws xob yog keeb kwm luv luv ntawm kev loj hlob ntawm hluav taws xob. Kev siv tshuab hluav taws xob yog ib qho thev naus laus zis tshiab uas tau tsim thaum kawg ntawm lub xyoo pua 19th thiab pib ntawm lub xyoo pua 20th. Hauv lub xyoo pua 20th, nws tau tsim sai tshaj plaws thiab tau siv dav. Nws tau dhau los ua lub cim tseem ceeb ntawm kev loj hlob ntawm kev tshawb fawb niaj hnub no thiab thev naus laus zis.
