Feem ntau hais lus, lub transceiver yog ib lub cuab yeej uas tuaj yeem xa thiab txais cov teeb liab, thaum lub transponder yog ib qho khoom uas nws lub processor tau programmed los saib xyuas cov teeb liab tuaj thiab muaj cov lus teb ua ntej hauv cov tes hauj lwm sib txuas lus fiber-optic. Qhov tseeb, transponders feem ntau yog tus cwj pwm los ntawm lawv cov ntaub ntawv ceev thiab qhov deb tshaj plaws uas lub teeb liab tuaj yeem mus. Transceivers thiab transponders yog txawv thiab tsis tuaj yeem hloov pauv. Tsab xov xwm no piav qhia txog qhov txawv ntawm transceivers thiab repeaters.
Cov Transceivers vs. Transponders: Cov Lus Txhais
Hauv kev sib txuas lus fiber optic, cov transceivers optical yog tsim los xa thiab txais cov teeb liab optical. Cov transceiver modules feem ntau yog cov khoom siv I/O (input/output) uas hloov tau kub, uas tau txuas rau hauv cov khoom siv network, xws li cov network switches, servers, thiab lwm yam. Cov optical transceivers feem ntau siv rau hauv cov chaw khaws ntaub ntawv, cov network enterprise, cloud computing, FTTX network systems. Muaj ntau hom transceivers, suav nrog 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G thiab txawm tias 400G transceivers. Lawv tuaj yeem siv nrog ntau yam cables lossis tooj liab cables rau kev xa mus ntev hauv cov network luv lossis ntev. Tsis tas li ntawd, muaj BiDi fiber optic transceivers uas tso cai rau cov modules xa thiab txais cov ntaub ntawv hla ib lub fiber kom yooj yim rau cov cabling systems, nce lub peev xwm network, thiab txo cov nqi. Tsis tas li ntawd, CWDM thiab DWDM modules uas multiplex ntau yam wavelengths rau ntawm ib lub fiber yog tsim rau kev xa mus ntev hauv WDM/OTN networks.
Qhov Sib Txawv Ntawm Transceiver thiab Transponder
Ob qho tib si repeaters thiab transceivers yog cov khoom siv zoo sib xws uas hloov cov teeb liab hluav taws xob puv-duplex mus rau cov teeb liab optical puv-duplex. Qhov txawv ntawm lawv yog tias lub optical fiber transceiver siv lub interface serial, uas tuaj yeem xa thiab txais cov teeb liab hauv tib lub module, thaum lub repeater siv lub interface parallel, uas xav tau ob lub optical fiber modules kom ua tiav tag nrho kev xa mus. Ntawd yog, lub repeater yuav tsum xa lub teeb liab los ntawm ib lub module ntawm ib sab, thiab lub module ntawm sab tod teb rau lub teeb liab ntawd.
Txawm hais tias lub transponder tuaj yeem yooj yim tswj cov teeb liab sib luag qis dua, nws muaj qhov loj dua thiab siv hluav taws xob ntau dua li lub transceiver. Tsis tas li ntawd, cov modules optical tsuas yog tuaj yeem muab kev hloov pauv hluav taws xob-rau-optical, thaum transponders tuaj yeem ua tiav kev hloov pauv hluav taws xob-rau-optical los ntawm ib qho wavelength mus rau lwm qhov. Yog li ntawd, transponders tuaj yeem xav txog li ob lub transceivers muab tso rov qab-rau-rov qab, uas yuav siv rau kev sib kis ntev hauv WDM systems uas tsis tuaj yeem ncav cuag los ntawm cov transceivers optical ib txwm muaj.
Xaus lus, cov transceivers thiab transponders yog qhov sib txawv hauv kev ua haujlwm thiab daim ntawv thov. Fiber repeaters tuaj yeem siv los hloov ntau hom teeb liab, suav nrog multimode rau ib hom, dual fiber rau ib fiber, thiab ib qho wavelength rau lwm qhov wavelength. Transceivers, uas tsuas yog tuaj yeem hloov cov teeb liab hluav taws xob rau cov teeb liab kho qhov muag, tau siv ntev hauv cov servers, cov hloov pauv network, thiab cov tes hauj lwm chaw khaws ntaub ntawv.
