10G TOSA rau 25G kis tau tus mob

A
Daim ntawv dawb ntawm 5G bearer optical modules hais txog lub tswvyim ntawm overclocking.

Cia peb pib sib tham seb daim duab qhov muag yuav zoo li cas yog tias 10GTOSA tau siv yam tsis muaj kev ua haujlwm ntawm ib qho25Gnti.
Lub qhov muag daim duab peb pom zoo li no:
C
Daim duab lub qhov muag yog ib qho kev sau ntawm cov pulses sau ntau lub sijhawm, zoo li lub lawj ntawm daim npav.
Daim duab lub qhov muag tau teeb tsa zoo li no: thawj kab nyob rau hauv pem hauv ntej ntawm lub ntsiab duab yog 101, ib qho peb -pulse ntu kav ib teev. Cov kab nruab nrab yog ib ntu me me nrog 0103 pulses. Kuj tseem muaj ntu nrog 111, 000, 110, 011, thiab lwm yam, mus txog 500 lossis 1000 pulses - qhov no yog daim duab peb pom.
Kuv tsuas yog xaiv ib qho: ib qho nrog 101 thiab 3 pulses.
D
Lub amplitude ntawm lub teeb liab zoo li qhov siab ntawm peb dhia; 1 dhia nce, 0 yog crouching down . 101 sawv cev rau lub sijhawm luv ntawm crouching mus dhia thiab rov qab mus rau crouching.Qhov kev ua haujlwm ntawm lub laser yog qhov yooj yim rau kev hloov kho 25 G teeb liab siv lub laser 100 Gb / s. Hauv lwm lo lus, lub laser no muaj bandwidth loj heev, ib yam li tus kws tshaj lij jumper uas dhia nrawm thiab siab.
E
Yog hais tias kuv tus ntxhais yuav tsum ua li no, nws yuav zoo; nws yuav suav hais tias yog ib qho kev dhia dhia ib txwm, nrog qhov nruab nrab dhia qhov siab thiab ceev.
Tab sis nrog kuv txiv, nws yuav tsis ua haujlwm. Kuv txiv lub peev xwm dhia tau txwv (xws li sim ua 25G ua haujlwm nrog 10G laser). Nws squat jumps yog clumsy thiab disorganized. Nws yuav hnov cov lus txib "los ntawm 0 mus rau 1," tab sis ua ntej nws tuaj yeem dhia, cov lus txib tom ntej tau muab, "los ntawm 1 txog 0." Yog li nws NW nyuam qhuav tswj kom ua tiav 010 txav.
Yog li ntawd, siv 10G TOSA los hloov kho lub teeb liab 25Gb / s muaj ob qhov teeb meem tseem ceeb. Ua ntej, daim duab qhov muag zoo nkaus li txaus ntshai.
Qhov muag kaw yog kim, ua rau lub qhov muag daim duab peb sab thiab cov ntaub ntawv tsis zoo sib kis tau zoo. Txawm li cas los xij, nws tsis tuaj yeem siv tsis tau, vim tias ntev npaum li tus neeg txais tuaj yeem paub txog lub teeb liab, nws zoo. Nws tsuas yog ib qho teeb meem ntawm kev txheeb xyuas 0s thiab 1s, zoo li squatting thiab dhia.
Yog hais tias tus kws txiav txim plaub ntug tau soj ntsuam qhov squatting thiab dhia, kuv txiv qhov kev txav tsis zoo yuav ua tsis tiav. Hauv lwm lo lus, kev txais tos zoo tib yam yuav tsis txaus.
Tab sis yog tias kuv txiv sim ua tib zoo mloog thiab dhia ntau dua, thiab kuv niam yuav hla tus neeg txais kev txhais lus, ces nws zoo. Kuv niam, nrog rau nws txoj kev ua neej nplua nuj, tuaj yeem sau qhov khoob ntawm kuv txiv txoj kev txav tsis zoo.
Los ntawm ib qho kev pom zoo, siv lub low-bandwidth laser los hloov qhov siab-ceev teeb liab ua rau tsis txaus modulation bandwidth, siab qhov muag- kaw cov nqi, thiab muaj zog inter{3}} cim cuam tshuam. Yog li ntawd, tus receiver ua qhov sib npaug, uas siv cov teeb liab backend ua los them rau qhov tsis txaus ntawm lub transmitter lub teeb liab zoo, aiming kom paub qhov txawv ntawm 1s thiab 0s.
Qhov sib npaug yooj yim tshaj plaws yog CTLE lim. Yog tias qhov siab -frequency signal attenuates significantly while transmission, the receiver's filtering bandwidth tseem tsis hloov; yog tias qhov tsawg -frequency signal attenuates tsawg, tus txais yuav xaiv txo nws qhov amplitude.
10 GTOSA yog siv rau ntawm 25G teeb liab rau ob lub hom phiaj tseem ceeb: ua ntej- tsom rau ntawm lub transmitter thiab, qhov tseem ceeb tshaj, kev sib npaug ntawm tus txais. Qhov no tso cai rau kev txheeb xyuas qhov tsis zoo 0s thiab 1s yam tsis muaj kev txhais lus yuam kev, yog li tshem tawm qhov yuam kev me ntsis.
Tus neeg txais kev sib npaug tuaj yeem ua tiav ntau txoj hauv kev, qhov yooj yim tshaj plaws yog CTLE, lossis linear equalization.
