Optical transceivers kuj yog cov khoom siv kho qhov muag pom kev sib kis. Txawv teb chaws optical transceivers muaj cov cuab yeej paub tab tab sis kim. Txawm hais tias domestic optical transceivers tsis yog li paub tab hauv tshuab, lawv tsis kim txaus los cuam tshuam nrog sab hauv. Tom qab ntawd qhov kev xaiv ntawm optical transceivers yog dab tsi?

Kev ceev faj rau kev yuav khoom optical transceivers: Los ntawm cov teeb liab xa mus rau qhov muag fiber ntau, optical transceivers tuaj yeem muab faib ua analog optical transceivers raws li analog technology thiab digital optical transceivers raws li cov thev naus laus zis digital. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm analog optical transceiver yog tsis muaj dab tsi ntau tshaj li kev hloov kho thiab demodulation, lim thiab teeb liab sib xyaw, thiab lwm yam. Txawm hais tias nws yog LED lossis LD, nws cov yam ntxwv photoelectric modulation tsis yog linear. Nyob rau hauv cov txheej txheem kis tau tus mob, distortion, cuam tshuam thiab lwm yam inevitable teeb meem nyob rau hauv analog processing yog inevitable, thiab muaj insurmountable technologies nyob rau hauv loj-muaj peev xwm kis tau tus mob thiab multi-kev pab cuam sib xyaw kis tau tus mob. nyuaj.

Qhov xwm txheej ntawm digital optical transceivers txawv. Tsuas muaj ob lub xeev ntawm "fiber thiab "tsis muaj fiber ntau" hauv cov fiber ntau optical. Yog li ntawd, lub linearity ntawm lub teeb qhov chaw tsis siab los yog yuav luag tsis muaj qhov yuav tsum tau, yog li tsis txhob teeb liab poob nyob rau hauv cov txheej txheem ua. Tsis tas li ntawd, digital optical transceivers yog qhov yooj yim rau kev ua tiav ntau cov channel thiab sib xyaw ua ke ntawm ntau lub teeb liab. Txij li thaum lawv tsuas yog hloov mus rau hauv cov teeb liab digital, kev sib kis ntawm ntau cov channel thiab ntau lub teeb liab tuaj yeem pom tau yooj yim nrog kev pab los ntawm TDM (Time Division Multiplexing) thev naus laus zis. Cov kws tsim khoom siv kho qhov muag uas twb muaj lawm tuaj yeem xa tawm 10 cov duab yees duab uas tsis muaj lub sijhawm tiag tiag ntawm ib lub sijhawm wavelength channel.

Optical fiber network topology, optical fiber network topology txiav txim siab hom video optical transceiver. Raws li lub topology ntawm optical fiber kis tau tus mob network, ntxiv rau cov tsoos point-to-point kis tau tus mob optical transceivers, kuj muaj node-type thiab nplhaib network optical transceivers xaiv los ntawm. Cov node-hom video optical transceiver muab cov kab hauv ntej-kawg rau hauv cov saw hlau los yog tsob ntoo network. Lub tshuab node ua ntej tau txais cov teeb liab ntawm txhua qhov ntawm node, hloov mus rau hauv lub teeb liab hluav taws xob, thiab tom qab ntawd sib pauv thiab multiplexes lub teeb liab nrog lub hauv paus ntawm lub zos. Tom qab lub photoelectric hloov dua siab tshiab, WDM thev naus laus zis yog siv rau multiplexing. Siv cov fiber ntau optical rau kev sib kis. Tsis muaj analog-rau-digital hloov dua siab tshiab yog ua ntawm txhua qhov node, uas txo cov teeb liab attenuation.

Kev sib kis ceev ntawm optical transceiver yog ceev, lub vijtsam yog qhov tseeb, thiab nws tuaj yeem siv rau txhua yam ntawm sab nraum zoov. Nws muaj ntau yam kev ua tau zoo thiab siv dav hauv kev lag luam.
