Pluggable optical modules (tseem hu ua optical transceivers) tam sim no dav siv nyob rau hauv cov ntaub ntawv chaw, cov tsev kawm ntawv lossis chaw ua haujlwm pabcuam.
Tag nrho cov chaw zov me nyuam cov ntaub ntawv (txhua txoj kev khiav hauv thiab tawm ntawm cov ntaub ntawv chaw) yuav tsum nce txog 20 Z bytes ib xyoo los ntawm 2021, nce ntawm tsuas yog 7 Z bytes hauv xyoo 2016. Cov ntaub ntawv chaw tsheb thoob ntiaj teb yuav loj hlob ntawm qhov sib npaug ntawm txhua xyoo ntawm 25 % thiab huab chaw nruab nrab cov ntaub ntawv yuav nce nyob rau qhov sib npaug ntawm txhua xyoo ntawm 27%. Los ntawm 2016 txog 2021, qhov kev loj hlob tau yog 3.3 npaug.
Dab tsi yog qhov kev tsav tsheb loj hauv kev tsav tsheb yog txoj kev loj hlob hauv cov kab sib txuas, raws li peb tau pom, los ntawm 10G txog 40G, tom qab ntawd mus rau 100G thiab tam sim no mus rau 400G. 100G pluggable optical module tam sim no xa mus rau cov ntawv thov loj teev chaw, thiab kho kom zoo dua mus rau 400G yog npaj, raws li router / hloov chaw nres nkoj tam sim no txhawb rau 400G.
Txoj kev loj hlob hauv kev tsheb" hauv cov ntaub ntawv chaw" tau txais ceev nrawm rau cov khoom siv network txuas ntxiv kom txhawb nqa chaw nres nkoj ntau dua thiab xa nrawm dua. Cov cuab yeej no, nyeg, yuav pab txhawb kev faib loj ntawm cov khoos phis tawj hluav taws xob kom nrawm txuas mus rau ntau cov khaubncaws sab nraud povtseg ntawm lub network.
Raws li router / hloov chaw nres nkoj tus nqi nce siab, tus nqi rau ib ntsis tau tsis kam tsawg vim muaj kev nce qib hauv cov chips (ASICS), thiab peb tseem tau txais txiaj ntsig zoo los ntawm Moore' s txoj cai hauv qhov no. Txawm li cas los xij, txawm hais tias tus nqi rau ib qho ntawm pluggable optical modules kuj poob, nws tsis tau poob sai npaum li router / hloov cov nqi.
Raws li qhov tshwm sim, nrog qhov nce ntawm tus nqi ntsis, pluggable optical module tso nyiaj rau ib qho kev faib ua feem ntau ntawm cov nqi kho vajtse tag nrho. Piv txwv, ntawm 10G tus nqi, cov kho qhov muag xam tau suav txog 10% ntawm tag nrho cov nqi ntawm cov ntaub ntawv nruab nrab network network hardware. Thaum peb hloov kho mus rau 400G, qhov kho qhov muag tau lees paub rau ntau dua 50% ntawm tag nrho cov nqi kho vajtse.
Nrog rau qhov nce ntawm tus nqi hluav taws xob kho qhov muag tsim, qhov tsim thiab tsim cov khoom siv ntawm pluggable optical module kuj nce ntxiv. Thaum pib ntawm 100G, qhov no coj mus rau pluggable optical modules lagging router / hloov ASICS nyob rau hauv cov nqe lus ntawm muaj thiab feem ntau ncua lub network kev hloov kho tshiab kom tau raws li cov bandwidth siab dua.
Cov tiam tom ntej hauv cov chaw khaws ntaub ntawv cuam tshuam txog ASIC kev ua haujlwm tsav lub router thiab hloov kev txhim kho. ASIC kev ua haujlwm yuav txuas ntxiv ntawm 10Tb rau 25Tb rau 51Tb thiab siab dua, uas yuav tsum muaj qhov sib thooj ntawm cov hluav taws xob teeb ntawm txhua I / O (tawm tswv yim / tawm) tus pin hauv ASIC. Qhov hluav taws xob teeb liab no yuav nce los ntawm 25Gb / s mus rau 50Gb / s mus rau 100Gb / s los txhawb tag nrho cov peev txheej ntawm cov tswv yim / tawm ASIC. Txhua lub sij hawm tus nqi no nce siab qhov kev sib tw ntawm kev xa cov teeb liab hluav taws xob los ntawm daim npav cable rau router / pob vaj huam sib luag nce siab.
Txhawm rau daws qhov kev sib tw no, kev lag luam yuav nyob rau qee lub sij hawm pib cia siab rau qhov muag dua li cov cim hluav taws xob, txawm tias qhov kis tau yog tsuas yog ob peb ntiv tes los ntawm sab hauv ntawm daim npav hloov. Yog li no, qhov sib koom tes ntawm qhov kho qhov muag ntawm cov xov tooj hluav taws xob thiab nti ua qhov tseem ceeb yav tom ntej. Tsuas yog txoj hauv kev no tuaj yeem nruam kev hloov kho hauv cov kev hloov pauv thiab hloov pauv tau kom ntseeg tau.
Kev lag luam thev naus laus zis tseem vam khom" sawv ib leeg" Cov rooj sibtham uas muaj kev sibtham thiab kev sib dhos. Yog tias peb yuav muab piv rau cov kev lag luam semiconductor (hauv qhov kev lag luam semiconductor, tsis tshua muaj kev ua haujlwm nyuaj nrog kev pab ntawm cov txheej txheem tsis xws luag tau muab tso ua ke rau hauv cov nti (ASIC), cov txheej txheem no tsis siv neeg, nrog tsawg lossis tsis muaj kev cia siab rau tib neeg-khoos phis tawj sib cuam tshuam) , peb tuaj yeem txiav txim siab siv qhov txheej txheem tsis siv neeg los tswj" lub teeb liab," dua li" hluav taws xob cov cim" hauv cov txheej txheem semiconductor. Qhov kev cia siab ntawm silicon photonics yog los siv cov txheej txheem hauv kev lag luam semiconductor los kho kom zoo dua tag nrho cov kev tsim khoom ntawm cov qauv kho qhov muag.
Hauv cov ntsiab lus, cov chaw zov me nyuam ntaub ntawv tam sim no cia siab rau cov kho qhov muag hluav taws xob rau cov ntawv thov luv heev (GG lt; 10m). 100G optical module yog cov thev naus laus zis nyob niaj hnub no' s cov chaw khaws ntaub ntawv thiab cia siab tias yuav tsum tsiv mus rau 400G thiab siab dua yav tom ntej.
Raws li routing / hloov chaw nres nkoj cov nqi txuas ntxiv tau txais txiaj ntsig los ntawm kev nce qib ntawm kev lag luam chip, tam sim no kho qhov muag module tau nyob hauv qhov feem ntau ntawm tus nqi tag nrho, cisco yuav yog li ntawd kho qhov muag module ua lub tshuab tseem ceeb tshawb fawb thiab kev txhim kho, nrog nti kom paub tseeb tias peb muaj peev xwm ua kom raws li qhov muaj ntawm kev txhim kho ntawm chip kev ua tau zoo, los txhawb txoj kev nce qib hauv cov nqi thiab kev ua tau zoo.
Peb paub tias nyob rau lub sijhawm dhau los, peb yuav tsum ua kom suav cov nti thiab cov kho qhov muag txuas ntxiv txuas ntxiv nthuav cov kev ua tau zoo ntawm cov hloov thiab cov routers. Cisco tseem yuav nqis peev ntxiv hauv chips thiab optical module kom ntseeg tau tias peb tuaj yeem xa cov kev daws teeb meem kom tau raws li peb cov neeg siv' loj hlob xav tau rau kev ua tau zoo hloov kho.
