Peblub teb chawsxov tooj optical transceiverstau tsim kho sai nrog kev txhim kho ntawm kev soj ntsuam kev lag luam.Los ntawm analog mus rau digital, thiab tom qab ntawd los ntawm digital mus rau cov ntsiab lus siab, lawv tau nce mus tas li.Tom qab xyoo ntawm kev tsub zuj zuj ntawm technical, lawv tau tsim mus rau ib tug heev paub tab theem.Cov xov tooj optical transceivers tsis tau ua ntau yam hauv kev siv tshuab, tab sis qee qhov haujlwm tshwj xeeb tseem tuaj yeem tsim thiab ua tiav hauv cov ntawv thov sib faib.Nrog rau kev txhim kho cov kev ua tau zoo xws li kev ruaj ntseg thiab lub peev xwm, qhov no kuj yog lub zog tsav tsheb rau cov xov tooj optical transceiver manufacturers kom tsis txhob nkees nrhiav kev tawg.

Tsis muaj kev txwv rau kev txhim kho thiab kev tsim kho tshiab, thiab kev ua haujlwm ruaj khov yog qhov tseem ceeb tshaj plaws.Thaum cov thev naus laus zis ntawm optical transceivers rau xov tooj yog qhov paub tab, ntau lub tuam txhab tig lawv txoj kev loj hlob mus rau kev txhim kho cov khoom lag luam.Tam sim no, kev ua tau zoo ntawm optical transceivers feem ntau yog txhim kho los ntawm cov ntsiab lus hauv qab no:

Thawj yog kev txhim kho ntawm ib hom.Cov fiber ntau optical tuaj yeem muab faib ua ntau hom thiab ib hom raws li kev sib kis ntawm lub teeb hauv nws.Ib hom tuaj yeem zam kev hloov pauv hloov pauv, thiab muaj cov txiaj ntsig sib kis tau zoo, tsis yooj yim cuam tshuam, thiab muaj qhov sib kis loj ntawm bandwidth thiab muaj peev xwm kis tau tus mob loj.Hloov mus rau qhov muaj peev xwm loj, kev sib kis mus ntev.

Qhov thib ob yog modular thiab hybrid access design.Cov qauv tsim qauv yog hloov tau thiab hloov tau, uas tuaj yeem muab kev nthuav dav ntxiv rau kev tsim kho lub cev;Nrog cov qauv ntawm digitalization, kev sib koom ua ke ntawm SDI thev naus laus zis, thiab kev sib koom ua ke ntawm cov khoom sib txawv ua rau tsis yooj yim rau cov tuam txhab.Yog li ntawd, .Ntxiv nrog rau cov qauv tsim qauv, kev tsim qauv siv hybrid kuj tseem yuav tsum tau, muab RJ-45 network interface, BNC interface, thiab lwm yam hauv cov cuab yeej, kom ob qho tib si analog teeb liab thiab cov teeb liab hauv network tuaj yeem xa mus rau tib lub optical transceiver.

Qhov thib peb yog txhawm rau txhim kho cov ntawv thov ntawm xov tooj optical transceivers.Cov cuab yeej no yuav txo tau cov khoom lag luam rau ib lossis ob qhov tshwj xeeb, thiab cov neeg siv khoom tuaj yeem nkag mus rau lawv ntawm qhov xav tau.Raws li qhov xwm txheej ntawm qhov chaw siv fiber ntau optical, nws yooj yim rau kev npaj, thiab lub xov tooj optical transceiver yuav tsis raug txwv los ntawm point-to-point, node, nplhaib, aggregation, thiab lwm yam. Ib qho khoom siv tau tshaj txhua txoj kev nkag. , zoo heev txo tus naj npawb ntawm optical fibers siv.

Qhov thib plaub yog daim ntawv thov kev siv tshuab multiplexing (lub ntsiab lus dav dav rau EDM, TDM, thiab WDM), uas tsuas yog daws qhov teeb meem ntawm kev sib kis me me ntawm ib qho fiber ntau, tshwj xeeb tshaj yog daim ntawv thov ntawm HD-SDI, uas nyob hauv lub bandwidth loj thiab muaj. ib lub lag luam loj ntim.Yog tias cov tshuab multiplexing thiab wavelength division multiplexing technology tuaj yeem ua ke, lub peev xwm tuaj yeem txhim kho ntau zaus.Yog li ntawd, kev tshawb fawb thiab kev loj hlob ntawm cov tshuab multiplexing yog qhov tseem ceeb tshwj xeeb.
