Optical Network Design: Phau Ntawv Qhia 5-kauj ruam [2026]

Kev lag luam datacom kho qhov muag tau loj hlob ntau dua 60% hauv 2025, tshaj $ 16 nphom hauv cov nyiaj tau los, thaum 800G transceiver xa khoom tau nce ob xyoos -ntawm- xyoo (Taw qhia). Cov lej no rov sau cov hauv paus ntsiab lus rau txhua pab pawg npaj cov phiaj xwm fiber ntau niaj hnub no. Optical network tsim tsis yog ib qho teeb meem ntawm kev xaiv lub topology thiab khiav cable. Nws yog ib ntus ntawm kev txiav txim siab engineering qhov twg qhov tsis zoo ntawm qhov kev npaj theem sib txuas ua rau rau -daim duab kho cov nqi tom qab xa mus.

 

Phau ntawv qhia no taug kev los ntawm tsib kauj ruam uas peb siv thaum pab cov neeg siv khoom npaj kho qhov muag txuas, los ntawm kev xav tau txhais los ntawm kev xaiv WDM architecture. Nws tau sau los ntawm qhov kev xav ntawm cov chaw tsim khoom uas xa cov transceivers thiab tom qab ntawd txhawb cov modules los ntawm kev xa tawm tsis ua haujlwm, uas txhais tau tias peb pom ob qho tib si theoretical tsim thiab qhov tshwm sim tiag tiag thaum lub teeb hits iav.

 

Yuav ua li cas zoo li hauv kev xyaum: lub rooj sib txuas pob nyiaj siv uas txhob txwm tshaj tawm kev tsim tsis tau ntawm −5.1 dB, cov ntaub ntawv attenuation tiag tiag los ntawm 20- xyoo-laus cov nroj tsuag sab nraud, thiab qhov tshwj xeeb WDM kev txiav txim siab uas feem ntau cov fiber optic network npaj qhia tawm tsis meej.

 

 

Txhua qhov kev tsim kho qhov muag network pib nrog peb qhov kev txwv, thiab tau txais lawv tsis ncaj ncees lawm hauv thawj lub lim tiam lav rov tsim dua tom qab. Qhov peb yog qhov kev thov bandwidth tam sim no, qhov siab tshaj plaws kis tau tus mob nyob rau ib qhov txuas, thiab qhov kev npaj muaj peev xwm loj hlob tshaj peb mus rau tsib xyoos. Lawv cuam tshuam: hloov ib qho thiab tag nrho pawg pawg txav nrog nws.

 

Rau cov ntaub ntawv chaw kho qhov muag network architecture, pawg nyob deb tseem ceeb vim lawv hais cov hom fiber ntau thiab cov chav kawm transceiver. Intra- tsev txuas hauv qab 300 meters muaj keeb kwm siv multimode fiber ntau thiab SR-chav kawm transceivers. Kev sib txuas hauv tsev kawm ntawv thiab metro txuas mus txog 1 txog 80 kis lus mev xav tau ib qho - hom fiber ntau nrog LR, ER, lossis ZR-chav kawm optics. Ntev-kev txuas mus dhau 80 mais xav tau kev siv tshuab ua kom muaj suab nrov. Tab sis qhov ceev tsiv teb tsaws ntawm 100G mus rau 400G thiab tam sim no 800G yog compressing cov ciam teb. Qhov twg multimode OM4 fiber ntau ib zaug txhawb 100G tshaj 100 meters, 400G SR8 thawb qhov ntawd mus rau 30 meters ntawm tib lub fiber ntau, thiab qhov kev txwv ib leeg yog hloov kho qhov kev txiav txim siab tsim kho qhov muag rau cov ntaub ntawv tshiab tsim thoob ntiaj teb.

 

Kev loj hlob projection yog qhov feem ntau underestimated. Lub network tsim rau 100G ib qhov chaw nres nkoj hnub no yuav xav tau kev hloov kho forklift los txhawb 400G hauv 24 lub hlis yog tias cov nroj tsuag fiber ntau tsis tuaj yeem ua kom dav dua -bandwidth transceivers lossis wavelengths ntxiv. Nco ntsoov qhia cov suav fiber ntau thiab cov kav dej muaj peev xwm tsawg kawg ib tiam dhau ntawm txoj kev npaj tam sim no. Tus nqi ntawm kev rub cov fiber ntau yog ua los ntawm kev ua haujlwm thiab kev ua haujlwm hauv pej xeem, tsis yog iav.

 

 

Cov nroj tsuag lub cev, cov qauv kev khiav tsheb, thiab kev tiv thaiv yuav tsum tau sib koom ua ke hais tias qhov twg topology ua haujlwm.

 

Point-rau- cov ntsiab lus txuas tseem yog qhov kev xaiv raug rau cov ntaub ntawv chaw sib cuam tshuam qhov chaw uas ob qhov chaw sib pauv siab - muaj peev xwm khiav tsheb yam tsis muaj cov ntsiab lus poob nruab nrab. Ntiv nplhaib topologies haum metro tes hauj lwm nrog ntau cov nodes raws ib txoj hauv kev, nrog ua - nyob rau hauv kev tiv thaiv: tsheb reroutes nyob ib ncig ntawm ib tug fiber txiav nyob rau hauv lub opposite direction. Mesh topologies tshwm sim hauv cov tes hauj lwm tseem ceeb uas kev sib raug zoo ntawm kev tsheb khiav yog ntau - rau -ntau thiab ib qho kev sib txuas tsis ua haujlwm yuav tsum tsis txhob cais ib qho.

 

Lub hnub qub topologies tswj kev nkag mus rau hauv tes hauj lwm, tshwj xeeb tshaj yog cov kev sib txuas lus kho qhov muag uas ua haujlwm rau cov tsev kawm ntawv hauv tsev kawm ntawv los ntawm lub chaw ua haujlwm hauv nruab nrab. Hauv fiber ntau optic network tsim rau cov tsev kawm ntawv kev lag luam, lub hnub qub layouts zoo huv si ntawm daim ntawv tab sis mloog zoo ib yam - taw tes - ntawm - kev pheej hmoo ua tsis tiav ntawm lub hauv paus ntawm lub hauv paus. Peb feem ntau qhia cov neeg siv khoom kom ntxiv yam tsawg kawg ib txoj hauv kev sib txawv ntawm cov tub ntxhais mus rau lub tsev loj tshaj plaws, txawm tias tsis muaj zog tsaus nti fiber ntau hnub no - vim tias tus nqi ntawm cov hlua ntawd tsis tseem ceeb piv rau 12-teev tsev kawm ntawv hluav taws xob thaum cov khoom noj tsuas yog txiav los ntawm tus neeg cog lus.

 

 

Qhov sib txawv ntawm cov tub ntxhais thiab metro duab cov optical network topology xaiv. Cov tes hauj lwm tseem ceeb muaj kev sib sau ua ke thoob plaws qhov ntev: siab ib - wavelength muaj peev xwm, tsawg kawg reconfiguration. Metro networks xav tau qhov yooj yim ntxiv los yog tso cov wavelengths ntawm tus neeg nodes. Qhov no yog qhov uas ROADMs nkag mus rau tus tsim. Qhov pib ua tau zoo: ROADMs ua rau kev txiav txim siab nyiaj txiag thaum koj muaj ntau tshaj plaub qhov ntxiv / tso rau ntawm lub nplhaib thiab xav tias yuav hloov lub wavelength ntau tshaj ob zaug hauv ib xyoos. Hauv qab no, zoo li qub MUX / DEMUX ntawm tus nqi qis yog yuav luag ib txwm yog cov lus teb zoo.

 

 

Yog hais tias muaj ib qho kev xam uas cais ib qho kev ua haujlwm kho qhov muag network tsim los ntawm kev siv theoretical, nws yog qhov txuas pob nyiaj siv. Txhua feem ntawm lub transmitter thiab receiver qhia txog kev poob, thiab cov nyiaj yuav tsum nyob twj ywm hauv qab ntawm lub transceiver lub hwj chim pob nyiaj siv los yog qhov txuas yuav tsis kaw.

 

Cov mis: lub zog pob nyiaj sib npaug ntawm cov khoom siv hluav taws xob tso tawm hluav taws xob (dBm) rho tawm tus txais rhiab heev (dBm). Uas muab tag nrho tolerable poob. Tag nrho cov peev txheej: fiber ntau attenuation (nyob deb × attenuation coefficient), connector poob (feem ntau 0.3-0.5 dB ib khub niam txiv, ibIEC 61300-3-34: Cov), splice poob (0.05-0.1 dB ib fusion splice), thiab tej multiplexer lossis splitter insertion poob. Tom qab ntawd rho tawm ib qho kev nyab xeeb. Cov txiaj ntsig zoo txhais tau tias siv tau. Negative txhais tau tias rov tsim dua tshiab.

 

Piv txwv ua haujlwm - Ib leeg-Mode WDM Txuas ntawm 10G (Optical Link Budget Calculation):

 

Parameter	Tus nqi
Hom Transceiver	SFP + ZR, 1550 nm
Transmitter tso zis (min)	-1 dBm
Txais rhiab heev	-24 dBm
Fais fab nyiaj txiag	23dB ib
Fiber ntev	60km ua
Fiber ntau attenuation (0.25 dB / km × 60)	15.0 dB
16-channel MUX/DEMUX (× 2)	9.0db ua
Patch vaj huam sib luag connectors (4 khub × 0.4 dB)	1.6dB ib
Kev nyab xeeb margin	2.5dB ua
Tag nrho poob	28.1dB ib
Kev tshwm sim	−5.1 dB → Txuas tsis kaw

 

Qhov piv txwv no txhob txwm tshaj tawm qhia qhov kev tsim tsis tau vim tias feem ntau cov kev taw qhia tsuas yog qhia cov neeg dhau mus. Qhov kev txhim kho ntawm no yog txo qis MUX / DEMUX channel suav (ib chav 8-channel feem ntau muaj qhov poob hauv 3-4 dB ntau ntawm cov chaw tsim khoom cov ntaub ntawv) lossis ntxiv ib qhoEDFA ua ntej - amplifier, los yog shortening lub span. Cov lej yuam kev sib tham, thiab qhov ntawd yog lub ntsiab lus ntawm kev khiav qhov kev sib txuas kho qhov muag siv nyiaj suav ua ntej xaj khoom.

 

Tus qauv ib zaug - hom fiber ntau attenuation yog 0.4 dB / km ntawm 1310 nm thiab kwv yees li 0.2 dB / km ntawm 1550 nm (Electrical Contractor Magazine). Tab sis cov nominal qhov tseem ceeb rau cov fiber tshiab. Hauv peb cov neeg siv khoom xa tawm, peb tsis tu ncua ntsuas 0.35-0.45 dB / km ntawm 1550 nm ntawm fiber ntau tau teeb tsa ntau dua 15 xyoo dhau los, tshwj xeeb tshaj yog qhov chaw raug cuam tshuam los yog cov ntaub ntawv tsis zoo splice yog yam tseem ceeb. CovMBC network upgradeyog ib qho piv txwv meej: tib yam 400G ZR + transceivers mus txog 83 km ntawm cov ntu tshiab fiber ntau tab sis tsuas yog 40-60 km ntawm cov txheej txheem qub, qhov sib txawv uas cov lus nominal yuav tsis kwv yees.

 

Kev sib cav txog kev nyab xeeb margin tsim nyog tau txais kev saib xyuas meej. Kev lag luam cov ntaub ntawv qhia txog qhov twg los ntawm 1.7 dB mus rau 3 dB, thiab tsis muaj daim duab yog qhov tseeb. Cov npoo ntawm 1.7 dB yog txaus rau huab cua- tswj cov ntaub ntawv chaw ib puag ncig nrog siab - cov khoom sib txuas zoo thiab kev saib xyuas tsis tu ncua. Cov npoo ntawm 3 dB lossis ntau dua yog qhov ua tau zoo rau cov nroj tsuag sab nraum zoov, huab cua fiber ntau, lossis ib qho kev sib txuas uas qhov kev soj ntsuam txuas yuav tsis tshua muaj. Sib cais qhov sib txawv ntawm 2 dB rau txhua qhov xwm txheej, raws li qee cov lus qhia pom zoo, tsis txaus siab rau ob lub chaw pw hav zoov - nws dhau -tsim kev txuas sab hauv tsev thiab hauv qab -tsim sab nraum zoov.

 

 

Kev xaiv transceiver ua raws li kev txiav txim siab ib ntus: cov ntaub ntawv tus nqi ua ntej, tom qab ntawd nyob deb, tom qab ntawd hom fiber ntau, tom qab ntawv module daim ntawv. Ib qho 400G yuav tsum tau tshaj 10 km ntawm ib zaug - hom fiber ntau cov ntsiab lus rau aQSFP-DD DR4 lossis FR4. Ib qho 100G yuav tsum tau tshaj 80 km taw qhia rau QSFP28 ZR lossis coherent CFP2 DCO, nyob ntawm seb puas xav tau kev koom ua ke DWDM. Cov kab ke ntawd suab ncaj nraim, tab sis kev sib txuas lus pluggable optics tau tawg ntau ntawm cov kauj ruam mus rau hauv ib qho, thiab qhov ntawd hloov kho qhov muag network tsim cov kev coj ua zoo tshaj plaws rau txhua qhov txuas tshaj 40 km.

 

 

Tus qauv OIF 400ZR ntim cov DSP sib koom ua ke, tsav tsheb, thiab TIA rau hauv tus qauv QSFP-DD form factor. Lub transceiver tam sim no ua haujlwm ua haujlwm uas yav dhau los xav tau ib qho kev hloov pauv ib leeg ntawm daim npav tshwj xeeb. Koj tuaj yeem tsim DWDM txuas los ntawm qhov chaw nres nkoj router sab nraud, yam tsis muaj lub thawv thauj khoom sib cais, muab lub router lub hnab ntawv thermal txhawb nqa kwv yees li 15-20 W rau ib lub module uas sib txuas nrog pluggables noj (raws li OIF 400ZR Daim Ntawv Pom Zoo Ua Haujlwm).

 

Thib peb-kev sib raug zoo ntawm tog transceiver tseem yog qhov feem ntau ntawm kev xa tawm qeeb uas peb ua haujlwm ntawm FB-LINK. OIF thiab IEEE cov qauv txhais tau hais tias kho qhov muag thiab hluav taws xob sib cuam tshuam, tab sis tus tswv tsev - sab firmware tus cwj pwm, cov kev kuaj mob digital, thiab tus neeg muag khoom- tshwj xeeb coding txhua tus tsim cov rooj plaub ntug uas tus qauv - ua raws cov qauv ua rau muaj qhov cuam tshuam txuas rau ntawm lub platform tshwj xeeb. Peb khiav qhov kev sib tw sib tw thoob plaws cov tsev neeg hloov pauv loj ua ntej xa khoom - tsis yog vim cov qauv tawg, tab sis vim qhov kev siv qhov sib txawv ntawm qhov spec thiab qhov chaw nres nkoj khiav yog qhov feem ntau daim pib pib. Rau pab pawg ntsuam xyuaspluggable transceiver architectures hauv kev nthuav dav, qhov kev sib cav txog kev saib xyuas yog qhov tseem ceeb: QSFP ua tsis tau tejyam -DD modules swaps tawm hauv ob feeb nrog xoom cuam tshuam rau cov chaw nres nkoj uas nyob ib sab.

 

800G tiam twb tau xa khoom hauv ntim rau cov ntawv thov hyperscale, thiab 1.6T transceivers tau nkag mus rau thawj zaug. OSFP-XD tau raug qauv raws li thawj 1.6T daim ntawv foos, nrog 92% ntawm cov ntawv cog lus hyperscale qhia nws (Introl). Rau cov lag luam tsim cov tes hauj lwm niaj hnub no: xa 400G raws li cov hauv paus ntsiab lus thiab xyuas kom lub platform hloov tau txais 800G modules hauv tib QSFP-DD lossis OSFP tawb, yog li txoj kev txhim kho yog qhov hloov pauv hloov pauv, tsis yog hloov chassis.

 

 

Wavelength division multiplexing hloov ib khub fiber ntau mus rau hauv ib txoj kab ntau- txoj kev loj. CovCWDM-versus-DWDM xaivyog qhov kev txiav txim siab tseem ceeb ntawm kev tsim kho qhov muag network tsim qauv uas tsim cov duab ntev - lub sijhawm muaj peev xwm qab nthab thiab ib tus nqi -channel.

 

CWDM siv dav channel sib nrug (20 nm) thiab feem ntau txhawb 8 txog 18 wavelengths. Tsis muaj qhov kub thiab txias - tswj lasers yuav tsum tau, uas ua rau module nqi qis. Kev lag luam tawm -tawm yog nyob deb: CWDM cov channel nthuav dav tag nrho 1270-1610 nm ntau yam thiab tsis tuaj yeem ua kom tag nrho los ntawm tus qauv EDFA, yog li cov kev sib txuas sab saum toj ntawm 40-80 km. Rau kev sib txuas hauv tsev kawm ntawv thiab kev nkag mus rau metro rings nqa 10G lossis 25G ib channel, CWDM yog tus nqi- teb tau zoo.

 

DWDM siv nruj channel sib nrug, 100 GHz lossis 50 GHz hauv ITU-TC-band (ibITU-T G.694.1), txhawb 40 rau 80+ raws ntawm 1528.77 nm thiab 1560.61 nm. Vim tias txhua txoj hauv kev poob rau hauv EDFA lub qhov rais amplification, DWDM txuas tuaj yeem nthuav dav dua ntau pua mais. Rau ib qho 80-channel DWDM system ntawm 10 Gbps ib channel, ib-channel tso zis zog yuav tsum tau khaws cia ze li 1 dBm thiab OSNR yuav tsum tshaj 17 dB rau qhov kev lees paub me ntsis yuam kev (ResearchGate).

 

 

Ntawm no yog qhov kev txiav txim hu rau feem ntau cov lus qhia zam: nyob rau hauv 40-80 km ntau yam uas ob lub technologies tuaj yeem ua haujlwm, CWDM yeej ntawm tus nqi peev tab sis poob ntawm kev ua haujlwm scalability. Yog tias qhov kev kwv yees kev tsheb khiav qhia pom cov channel suav nyob qis dua 16 rau peb xyoos lossis ntau dua, CWDM yog qhov tseeb. Yog tias muaj qhov xwm txheej tiag tiag uas qhov kev thov hla 18 txoj hauv kev ua haujlwm ntawm fiber ntau lub neej, pib nrog DWDM, txawm tias tus nqi pib dua, zam tag nrho MUX / DEMUX hloov tom qab. Lub coherent 400ZR / ZR + modules peb tau hais ua ntej tsuas yog ua haujlwm hauv DWDM daim phiaj, yog li txhua qhov txuas uas npaj rau kev hloov kho txuas ntxiv yav tom ntej yuav tsum tau tsim los ntawm DWDM txij hnub ib.

 

Qhov kev sib tw ua tau zoo yog tias feem ntau pab pawg ua qauv kev txiav txim siab tsim kho qhov muag network no tsis muaj kev ntseeg siab peb - xyoo kev kwv yees tsheb. Yog tias qhov no piav qhia txog koj qhov xwm txheej, MBC kev xa tawm hais txog hauv Kauj Ruam 3 yog kev qhia: hla 100G nkaus thiab mus ncaj nraim mus rau 400G ntawm DWDM tau ua rau pheej yig dua li cov phiaj xwm qub, vim tias tus nqi ntawm ib qho kev sib txuas ntawm pluggables poob sai dua li txoj kev kwv yees.

 

 

Txawm tias muaj kev qhuab ntuas ntawm kev tsim kho qhov muag network tsim cov kev coj ua zoo tshaj plaws tuaj yeem tsim cov kev xa tawm tsis zoo thaum cov chaw dig muag tshwj xeeb tsis raug kuaj xyuas. Cov no yog qhov yuam kev peb pom feem ntau thaum txhawb cov neeg siv khoom los ntawm kev ua haujlwm.

 

Siv nominal attenuation ntawm cov laus fiber ntau.Tsim cov cuab yeej ua ntej rau 0.2 dB / km ntawm 1550 nm. Ntawm 20-xyoo- laus sab nraum cov nroj tsuag nrog ntau qhov kev kho splices, qhov tseeb ntsuas qhov poob tuaj yeem tshaj 0.4 dB/km, ob npaug ntawm cov fiber ntau poob hauv cov peev nyiaj txuas. Ib txwm siv OTDR- ntsuas qhov tseem ceeb rau cov fiber ntau uas twb muaj lawm, tsis yog catalog specs.

 

Tsis quav ntsej OTDR qhov xwm txheej ntawm thaj chaw tuag.Ib qho OTDR tsis tuaj yeem daws ob qhov xwm txheej ze dua li nws qhov chaw tuag, feem ntau 1 txog 5 meters nyob ntawm qhov dav ntawm mem tes. Nyob rau hauv ib lub chaw cov ntaub ntawv nrog tuab thaj vaj huam sib luag khiav, qhov uas nyob ib sab connector faults yuav tshwm sim raws li ib tug tshwm sim, npog qhov teeb meem uas tsuas yog nto nyob rau hauv lub tsheb. Ntxiv OTDR kev sim nrog qhov ntsuas qhov muag poob rau luv luv, siab - qhov sib txuas ceev.

 

Hauv qab - suav connector thiab splice poob.Ib qhov txuas pob nyiaj siv uas suav rau ob qhov kawg txuas tab sis tsis quav ntsej qhov nruab nrab ntawm thaj chaw, cov thav ntawv xa tawm, lossis thaj chaw splices yuav pom 2-4 dB poob qis dua qhov tseeb. Txhua khub niam txiv ntxiv 0.3–0.5 dB (ibIEC 61300-3-34: Cov). Ib lub tsev kawm ntawv txuas nrog plaub thaj vaj huam sib luag txhawb nqa 1.6–2.0 dB ntawm kev sib txuas ntawm ib leeg.

 

Plaub qhov yuam kev ntxiv muaj nyob rau hauv ib daim ntawv teev kev tsim kho qhov muag: sib xyaw ib zaug - hom thiab multimode fiber ntau (uas feem ntau yuav dhau qhov kev sim thawj zaug tab sis ua tsis tau lub lis piam tom qab qhov kub hloov pauv hloov modal coupling), tsim khoov lub vojvoog los ntawm kev xav tsis yog spec, hla ncej- xa tawm OTDR lub hauv paus, thiab tawm hauv cov ntsiab lus ntawm lub cev tsis ua haujlwm. Ob peb pom ua rau feem ntau rework yog hauv qab no.

 

Tsim khoov vojvoog los ntawm kev xav.Fiber khoov radius ua txhaum cai ua rau microfractures thiab lub teeb tawg uas tej zaum yuav tsis tshwm sim hauv kev sim thawj zaug tab sis degrade kev ua tau zoo dhau lub hlis. Standard ib leeg- hom fiber ntau nyob rau hauv load yuav tsum muaj tsawg kawg yog 30 mm khoov vojvoog; khoov-insensitive G.657.A2 fiber ntau tso cai rau 7.5 hli (Lub koom haum Fiber Optic). Qhia meej hom fiber ntau hauv daim ntawv tsim thiab tswj lub vojvoog thaum lub sijhawm teeb tsa, tsis yog tom qab.

 

Tsis muaj kev tswj xyuas lub cev ntawm cov ntsiab lus txiav.Lub koom haum Fiber Optic tau sau txog qhov xwm txheej tiag tiag uas tus thawj coj koom ua haujlwm tau txiav lub pob txha txuas txuas txuas rau cov neeg tuaj saib, cuam tshuam tag nrho LAN. Qhov kev txhim kho yog qhov yuav tsum tau tsim tshwj xeeb: txhua lub vaj huam sib luag nyob rau hauv 5 meters ntawm qhov tsis yog - thaj chaw txwv tau txais lub kaw lus kaw; Cov chaw nres nkoj qaum fiber ntau tau sau tias "ACTIVE - TSIS TAU DISCONNECT" hauv cov ntawv nyeem; thiab tshem tawm cov xwm txheej ntawm lub cev cov chaw nres nkoj ua rau automated NOC ceeb toom.

 

Ib txoj kev tshawb fawb luam tawm ntawm kev xa tawm fiber ntau hauv Ghana pom tias kev txiav fiber ntau txuas ntxiv tseem yog ib qho kev txhawb nqa loj tshaj plaws rau kev sib tham hauv xov tooj, uas tau tsav los ntawm cov ntaub ntawv tsis zoo thiab cov ntawv xa tsis tuaj - kev tswj hwm kev xa tawm. Peb caug-xya feem pua ​​​​ntawm cov neeg ua haujlwm tshawb fawb tau ntsuas lawv cov ntawv tshaj tawm- kev xa mus ua haujlwm tsis txaus (Wiley / Engineering Reports). Cov qauv zoo ib yam thoob plaws thaj chaw: txhua qhov kev teeb tsa yuav tsum muaj OTDR lub hauv paus khaws cia hauv qhov chaw muaj npe nyob rau hauv lub network cov ntaub ntawv kaw lus nyob rau hnub ntawm kev ua haujlwm, tsis tau sau rau hauv lub installer lub van thiab upload thaum yooj yim.

 

 

800G twb tau xa mus rau hauv ntim, nrog rau kev xa khoom loj hlob 60% xyoo-ntawm- xyoo thiab 1.6T nkag mus rau thawj zaug (Introl). Rau ibyav tom ntej -pov thawj optical network tsim, cov lus nug tsis yog seb puas yuav npaj rau 800G tab sis yuav ua li cas kom ntseeg tau cov nroj tsuag fiber ntau thiab hloov cov txheej txheem txhawb kev txhim kho yam tsis muaj kev ua haujlwm hauv pej xeem.

 

Lub co-packaged optics (CPO) tiv thaiv pluggable debate yog architectural diav rawg txhais cov ntaub ntawv chaw network tsim rau xyoo tom ntej. CPO integrates lub tshuab kho qhov muag hauv qhov hloov ASIC pob, tshem tawm pem hauv ntej - vaj huam sib luag transceivers thiab txo hwj chim. Kev lag luam tawm - tawm yog kev ruaj ntseg: photonic - txheej txheej hauv CPO tsim yuav xav tau hloov tag nrho lub rooj tsav xwm hloov. Ntev npaum li cov modules pluggable hauv QSFP-DD thiab OSFP daim ntawv tseem ceeb tseem ua tau raws li lub hom phiaj ntawm lub zog thiab qhov ntom ntom, thiab tam sim no lawv ua rau400G datacenter transceiver xa tawm, pluggable architectures tseem yog qhov kev nyab xeeb ua haujlwm thawj koom ruam rau kev lag luam thiab nruab nrab - teev cov tswv lag luam.

 

 

Kev taw qhia tswv yim rau kev tsim kho qhov muag network thiab kev npaj cov kauj ruam tau ua tiav niaj hnub no: xa 400G lossis 800G raws li ib qho -chaw nres nkoj hauv paus, xyuas kom txhua qhov kev khiav haujlwm fiber ntau muaj tsawg kawg 30% tsaus fiber ntau tshaj qhov chaw thau khoom tam sim no, thiab paub meej tias qhov hloov pauv platform txoj kev teeb tsa suav nrog OSFP-XD kev txhawb nqa rau 1.6T. Cov fiber ntau koj nruab rau xyoo no yuav nqa tsheb mus rau 15 txog 25 xyoo. Cov transceivers yuav raug hloov peb lossis plaub zaug dhau qhov ntawd. Tsim cov kev tsim kho vaj tse mus tas li generously thiab cov txheej pluggable economically.

 

 

Tsib qhov kev tsim kho qhov muag network cov kauj ruam saum toj no tsim ib ntu uas txhua qhov kev txiav txim siab txo qis cov kev xaiv rau yav tom ntej. Hla qhov txuas pob nyiaj siv thiab qhov kev xaiv transceiver dhau los ua qhov kwv yees. Hla qhov kev kwv yees kev loj hlob thiab WDM architecture dhau los ua cuab. Txhua dB ntawm cov npoo ua rau hauv cov qauv tsim nqi ib feem ntawm qhov nws raug nqi los daws teeb meem hauv kev tsim khoom.

 

Yog tias koj qhov project tom ntej no suav nrog 10G-rau-400G kev tsiv teb tsaws lossis kev xaiv transceiver hla ntau tus neeg muag khoom hloov chaw,peb pab neeg engineering validates link pob nyiaj tiv thaiv tshwj xeeb modules txhua hnubthiab tuaj yeem nias - sim koj tus qauv tsim ua ntej khoom siv nkoj.
