Vim yog qhov bandwidth siab thiab qhov attenuation qis uas cov fiber optical coj los, qhov ceev ntawm lub network tab tom nce qib loj heev. Cov thev naus laus zis fiber optic transceiver kuj tseem hloov pauv sai sai kom tau raws li qhov xav tau ntawm qhov ceev thiab lub peev xwm. Cia peb saib seb qhov kev nce qib no yuav cuam tshuam li cas rau cov chaw khaws ntaub ntawv.
Ib qho fiberlub tshuab txais xov tooj ntawm tesyog ib lub voj voog sib xyaw ua ke (IC) uas tuaj yeem xa thiab txais cov ntaub ntawv tau ywj pheej hauv ob qho kev taw qhia. Lub cuab yeej no muab lub tshuab xa thiab lub tshuab txais ua ke rau hauv ib lub module uas hloov cov teeb liab hluav taws xob mus rau hauv cov teeb liab kho qhov muag, ua rau cov teeb liab no xa tau zoo los ntawm lub server mus rau lub server hla cov xov hlau fiber optic.
Lub cov transmitter hloov pauvLub zog hluav taws xob nkag mus rau hauv qhov tso zis optical los ntawm lub laser diode lossis LED lub teeb qhov chaw (lub teeb raug txuas rau hauv lub fiber optical los ntawm lub connector thiab xa mus los ntawm lub fiber optic cable). Lub teeb los ntawm qhov kawg ntawm lub fiber yog txuas rau lub receiver, thiab lub detector hloov lub teeb mus rau hauv lub teeb liab hluav taws xob, uas yog conditioned rau kev siv los ntawm lub cuab yeej txais. Dab tsi nyob hauv lub fiber optic transceiver?
Cov khoom siv fiber ntau optical transceivers muaj cov transmitters, receivers, optical devices thiab chips. Lub chip feem ntau suav hais tias yog lub plawv ntawm lub fiber optic module. Nyob rau hauv xyoo tas los no, muaj kev txaus siab rau kev siv silicon photonics hauv transceiver chips - tsim lasers ntawm silicon thiab tom qab ntawd fusing optical Cheebtsam nrog silicon integrated circuits. Nws hais txog qhov xav tau kev sib txuas sai dua los ntawm rack mus rau rack thiab hla cov chaw khaws ntaub ntawv. Nws ua kom yooj yim rau cov txheej txheem sib dhos. Tsis tas li ntawd, transceivers tuaj yeem ua kom me dua, txo qhov chaw ntawm lub server tag nrho thiab ua kom cov chaw khaws ntaub ntawv me dua, leaner thaum tswj hwm qhov chaw nres nkoj siab. Ntawm qhov tod tes, qhov me dua txhais tau tias siv hluav taws xob tsawg dua thiab tus nqi qis dua.
Keeb Kwm Luv Luv ntawm Optical Transceivers
Kev siv cov thev naus laus zis silicon photonics hauv cov chips transceiver yog ib feem ntawm qhov pov thawj rau kev nce qib loj heev hauv cov thev naus laus zis fiber-optic transceiver. Qhov sib txawv yog tias cov fiber optic transceivers tab tom txav mus rau qhov loj me me dua thiab cov ntaub ntawv siab dua kom haum rau qhov nce ntxiv ntawm cov ntaub ntawv tsheb khiav los ntawm kev hloov pauv hauv Is Taws Nem.
