Optical modules yog optoelectronic li uas ua photoelectric thiab electro-optical conversion.Kev xa tawm kawg ntawm qhov kho qhov muag module hloov cov teeb liab hluav taws xob mus rau hauv lub teeb liab kho qhov muag, thiab qhov kawg tau txais hloov pauv cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob.Feiyu Fiber nthuav qhia daim ntawv thov ntawm optical modules nyob rau hauv ntau yam lag luam.Lub ntsiab daim ntawv thov teb ntawm optical modules muaj xws li: 1. Data center;2. Kev sib txuas lus txawb chaw nres tsheb;3. Passive wavelength faib system;4. SAN/NAS cia network;5. 5G bearer network.
1. Data center.
Lub chaw cov ntaub ntawv tam sim no tsis yog ib qho lossis ob peb chav computer, tab sis ib pawg ntawm cov ntaub ntawv chaw nyob.Txhawm rau kom paub txog kev ua haujlwm ib txwm muaj ntawm ntau yam kev pabcuam hauv Is Taws Nem thiab kev lag luam thov, cov chaw khaws ntaub ntawv yuav tsum tau ua haujlwm hauv kev sib koom tes.Lub sijhawm sib pauv loj ntawm cov ntaub ntawv ntawm cov chaw zov me nyuam tau tsim qhov kev thov rau cov ntaub ntawv chaw sib cuam tshuam kev sib txuas lus, thiab kev sib txuas lus fiber ntau tau dhau los ua qhov tsim nyog los ua kom muaj kev sib tshuam.
Sib txawv ntawm cov khoom siv sib txuas lus hauv kev sib txuas lus hauv network, kev sib txuas ntawm cov ntaub ntawv yuav tsum muaj kev ceev dua, kev siv hluav taws xob qis dua, thiab ntau dua miniaturization ntawm cov khoom siv hloov mus ua kom tiav cov ntaub ntawv loj dua thiab hnyav dua.Ib qho tseem ceeb uas txiav txim siab seb qhov kev ua yeeb yam no puas tuaj yeem pom tau yog qhov kho qhov muag module.
Data center kev sib txuas lus optical modules tuaj yeem muab faib ua peb pawg raws li hom kev sib txuas:
(1) Los ntawm cov ntaub ntawv chaw rau tus neeg siv, nws yog tsim los ntawm cov neeg siv kawg tus cwj pwm xws li nkag mus rau hauv huab los xauj lub vev xaib, xa thiab tau txais email, thiab cov kwj video;
(2) Data center interconnection, feem ntau yog siv rau cov ntaub ntawv replication, software thiab system upgrades;
(3) Nyob rau hauv cov ntaub ntawv chaw, nws yog tsuas yog siv rau cov ntaub ntawv khaws cia, tiam thiab tsuas.Raws li Cisco qhov kev kwv yees, kev sib txuas lus sab hauv ntawm cov ntaub ntawv chaw tso nyiaj rau ntau dua 70% ntawm kev sib txuas lus ntawm cov ntaub ntawv chaw.Txoj kev loj hlob zoo ntawm cov ntaub ntawv chaw tsim kho kuj tau yug los rau kev txhim kho cov khoom siv kho qhov muag kub ceev.
2. Cov chaw nres tsheb sib txuas lus txawb.
Lub chaw nres tsheb sib txuas lus hauv xov tooj yog hais txog lub xov tooj cua transceiver uas xa cov ntaub ntawv ntawm lub chaw sib txuas lus ntawm lub xov tooj ntawm tes thiab lub xov tooj ntawm tes hauv ib cheeb tsam xov tooj cua.
Tus neeg teb xov tooj lub chaw nres tsheb sib txuas lus mobile kuj xav tau cov khoom siv kho qhov muag kom paub txog kev sib txuas ntawm cov khoom siv.Lub hauv paus chaw nres tsheb muaj RRU thiab BBU cov khoom siv.Hauv daim ntawv thov, peb yuav tsum txuas cov kev sib txuas ntawm ob lub cuab yeej no, uas yuav tsum muaj peb cov khoom siv kho qhov muag.Hauv 4G network, cov cuab yeej siv los txuas BBU thiab RRU feem ntau yog 1.25G optical module, 2.5G optical module, 6G optical module, 10G optical module, thiab lwm yam.
3. Passive WDM system
Ntawm cov kev daws teeb meem tau txais los ntawm 5G fronthaul, passive WDM undoubtedly suav rau qhov feem ntau tshaj plaws.Passive WDM system muaj xim optical module, multiplexer thiab optical fiber.
Lub hauv paus ntsiab lus ntawm passive wavelength division thev naus laus zis yog siv WDM thev naus laus zis rau ob peb lub teeb pom kev kho qhov muag nrog cov wavelengths sib txawv thiab nqa cov ntaub ntawv hauv ib pob, thiab xa mus rau hauv ib qho fiber ntau kom paub txog kev sib kis ntawm cov kev pabcuam.WDM tuaj yeem xa tawm ntau lub teeb liab ib txhij nrog ib qho fiber ntau optical.Nws tuaj yeem xa tawm txhua lub teeb liab nrog lub teeb liab tshwj xeeb ntawm lub teeb uas phim lub teeb liab, thiab cov teeb liab ntawm qhov sib txawv wavelengths tuaj yeem sib cais ntawm qhov kawg tau txais.Lub passive wavelength division system feem ntau yog ib qho system uas muaj ob ntu: xim lub teeb module thiab OTM.
4. SAN/NAS cia network.
Nrog txoj kev loj hlob sai ntawm Internet thiab kev siv network, hom ntaub ntawv yuav tsum ua tiav los ntawm cov ntaub ntawv khaws cia cov ntaub ntawv tseem muaj ntau zuj zus, uas ua rau cov ntaub ntawv khaws cia cov ntaub ntawv ntsib cov teeb meem uas tsis tau muaj dua.Ntxiv cov khoom siv hauv network (Network Attached Storage, abbreviated li NAS) thiab cov chaw khaws cia hauv cheeb tsam (Storage Area Network, abbreviated as SAN), lawv tuaj yeem cais cov ntaub ntawv khaws cia cov ntaub ntawv los ntawm lub network thiab tus tswv tsev, ob qho tib si kev tswj hwm hauv nruab nrab ntawm cov ntaub ntawv cov ntaub ntawv, thiab Nrog zoo scalability, nws muab qhov zoo tshaj plaws kev daws teeb meem rau realizing centralized cov ntaub ntawv tswj.
Lub luag haujlwm tseem ceeb ntawm SAN / NAS cia network yog khaws cov ntaub ntawv.Ntawm lawv, SAN network feem ntau yog tsim los ntawm cov servers, fiber ntau channel keyboards, cov khoom siv khaws cia, thiab cov khoom siv sib kis (optical modules, fiber ntau jumpers);NAS cia network yog tsim los ntawm NAS cia, keyboards, Muaj cov khoom siv davhlau ya nyob twg (khoos phis tawj), kis tau tus mob (optical module, optical fiber jumper).
Nws yuav tsum raug sau tseg tias SAN network siv Fiber Channel optical modules thiab xav tau los txhawb FC Fiber Channel raws tu qauv, thaum lub optical modules siv nyob rau hauv NAS cia network tsuas yog yuav tsum tau ua raws li Ethernet raws tu qauv.
5. 5G bearer network.
5G network tau muab faib ua peb ntu, uas yog kev nkag mus rau network, bearer network thiab core network.Txhawm rau nkag siab txog kev sib raug zoo ntawm lawv, koj tuaj yeem xa mus rau daim duab hauv qab no:
5G bearer network feem ntau tau muab faib ua cov txheej txheem nkag hauv nroog, txheej txheej hauv nroog loj, thiab cov tub ntxhais kawm hauv nroog / cov kab hauv nroog kom paub txog kev ua haujlwm pem hauv ntej thiab nruab nrab ntawm 5G cov kev pabcuam.
Cov xwm txheej ntawm daim ntawv thov ntawm 5G fronthaul suav nrog kev sib txuas ntawm fiber ntau, passive WDM thiab nquag WDM, thiab lwm yam.
Yam yuav tsum tau ua rau optical modules hauv 5G fronthaul daim ntawv thov scenarios yog raws li nram no:
① Ua kom tau raws li qhov ntsuas kub ntawm qib kev lag luam, kev ntseeg siab siab: xav txog qhov chaw ua haujlwm sab nraum zoov, lub hauv ntej kho qhov muag module yuav tsum ua kom tau raws li qhov ntsuas kub ntawm -40 ℃ ~ + 85 ℃, thiab tseem yuav tsum tau ua kom tau raws li cov kev cai ntawm plua plav.
② Tus nqi qis: Qhov kev thov rau 5G optical modules zoo heev tshaj li ntawm 4G, tshwj xeeb tshaj yog rau fronthaul optical modules.Tus nqi qis yog ib qho tseem ceeb ntawm cov khoom siv kho qhov muag hauv 5G kev lag luam.5G nruab nrab thiab backhaul npog cov txheej txheem nkag, txheej txheej thiab txheej txheej tseem ceeb ntawm cheeb tsam nroog.Qhov yuav tsum tau kho qhov muag modules tsis ntau txawv ntawm qhov kho qhov muag module technology siv nyob rau hauv cov ntaub ntawv tam sim no.Cov txheej txheem nkag tau tsuas yog siv 25Gb / s, 50Gb / s, 100Gb / s Rau optical modules ntawm s thiab lwm tus nqi, DWDM optical modules nrog tus nqi ntawm 100Gb / s, 200Gb / s, thiab 400Gb / s feem ntau yuav siv ntawm aggregation txheej thiab saum toj no.
Thaum kawg, nws yuav tsum tau hais tias qhov kev thov loj hlob ntawm optical modules feem ntau yog nyob ntawm cov ntaub ntawv kev sib txuas lus kev lag luam thiab kev lag luam hauv xov tooj.Nyob rau hnub no cov ntaub ntawv hnub nyoog, kho qhov muag modules yog khi rau usher nyob rau hauv tshiab txoj kev loj hlob.
Huanet tuaj yeem muab txhua yam ntawm cov khoom siv kho qhov muag, txais tos hu rau tus nqi.
