Peb ntseeg tias ntau tus neeg siv muaj kev nkag siab qee yam ntawm optical transceivers.Ntau tus neeg siv tsis paub ntau txog optical modules.Optical modules yog ib feem tseem ceeb ntawm optical transceivers.Optical modules tseem ceeb heev rau optical transceivers, yog li dab tsi yog qhov kho qhov muag module thiab vim li cas nws thiaj tuaj yeem ua lub luag haujlwm loj hauv optical transceivers?

Optical module ntawm optical transceiver feem ntau yog siv nyob rau hauv lub caj qaum ntawm lub optical fiber network.Optical modules feem ntau muab faib ua GBIC, SFP, SFP +, XFP, SFF, CFP, thiab lwm yam, thiab hom kev kho qhov muag suav nrog SC thiab LC.Txawm li cas los xij, SFP, SFP +, XFP feem ntau siv niaj hnub no tsis yog GBIC.Qhov laj thawj yog vim li cas GBIC yog qhov loj thiab tawg yooj yim.Txawm li cas los xij, feem ntau siv SFP yog me me thiab pheej yig.Raws li hom, nws tuaj yeem muab faib ua ib hom optical modules thiab ntau hom optical modules.Tib hom optical modules yog tsim rau kev sib kis mus ntev;multi-mode optical modules yog tsim rau luv luv kis tau tus mob.

Cov khoom siv kho qhov muag tab tom txhim kho rau kev ua haujlwm me me, txhim kho (hluav taws xob / kho qhov muag, kho qhov muag / hluav taws xob hloov pauv) kev ua haujlwm, thiab txhim kho kev ntseeg tau;planar optical waveguide (PLC) thev naus laus zis yuav txo qhov ntim ntawm bidirectional / peb-directional optical Cheebtsam thiab txhim kho kev ntseeg tau ntawm cov khoom.Kev ua haujlwm thiab kev ua haujlwm ntawm cov chips sib xyaw ua ke tau ntxiv dag zog, kom lub ntim ntawm cov khoom siv kho qhov muag tau raug txo qis thiab kev ua haujlwm tau zoo tas li.Lub kaw lus tsis tu ncua tso cov kev xav tau tshiab rau kev ua haujlwm ntxiv ntawm lub module, thiab kev ua haujlwm ntse ntawm qhov kho qhov muag module yuav tsum tau txhim kho txuas ntxiv kom tau raws li qhov xav tau ntawm lub system.

Nyob rau hauv qhov tseeb, nyob rau hauv lub optical transceiver, qhov tseem ceeb ntawm lub optical module nyob deb tshaj lub core nti.Optical module yog tsim los ntawm optoelectronic li, functional circuits thiab optical interfaces.Cias muab, lub luag hauj lwm ntawm optical module yog photoelectric hloov dua siab tshiab.Qhov kawg kis tau hloov cov teeb liab hluav taws xob rau hauv cov teeb liab optical.Tom qab kis tau los ntawm cov khoom siv kho qhov muag, qhov kawg tau txais kev hloov pauv cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob, uas muaj txiaj ntsig zoo thiab muaj kev nyab xeeb dua li cov transceivers.Tom qab lub hwj chim qhib, lub optical module nyob rau hauv tus txheej txheem ntawm tas li emitting lub teeb, thiab yuav muaj attenuation nyob rau hauv lub sij hawm.Yog li ntawd, nws yog ib qho tseem ceeb heev kom paub qhov ua haujlwm ntawm qhov kho qhov muag module.

Peb yuav tsum siv lub ntsuas hluav taws xob kho qhov muag kom pom qhov zoo ntawm qhov kho qhov muag module.Feem ntau, thaum lub optical module tawm ntawm lub Hoobkas, tus thawj chaw tsim tshuaj paus yuav xa cov ntaub ntawv soj ntsuam zoo ntawm no batch rau cov chaw tsim tshuaj paus.Cov chaw tsim khoom siv lub ntsuas hluav taws xob kho qhov muag rau kev ntsuas qhov tseeb., Thaum qhov sib txawv nyob rau hauv qhov kev tshaj tawm, nws yog ib qho khoom tsim nyog.

Rau tus nqi kuaj nrog optical module, lub Hoobkas fais fab ntau yam yog -3 ~ 8dBm.Los ntawm kev sib piv cov lej, cov khoom siv kho qhov muag tuaj yeem txiav txim siab ua cov khoom tsim nyog.Nws yog tshwj xeeb yog ceeb toom tias qhov me me ntawm lub hwj chim tus nqi, qhov tsis muaj zog ntawm optical kev sib txuas lus muaj peev xwm;uas yog, lub hwj chim qis optical module tsis tuaj yeem ua qhov sib kis tau ntev.Raws li cov ntaub ntawv tseem ceeb hauv kev lag luam, qee qhov kev cob qhia me me yuav yuav cov khoom siv kho qhov muag thib ob, uas nws cov lej raug kho dua tshiab thiab siv cov khoom siv kho qhov muag luv luv.Obviously, qhov no tsis tshua muaj kev lav ris rau cov neeg siv.
