Muaj pes tsawg hom 100G optical modules

Cov qauv muaj feem xyuam rau kev lag luam kev sib txuas lus kho qhov muag feem ntau yog los ntawm cov koom haum xws li IEEE, ITU, thiab MSA Industry Alliance.Muaj ntau yam qauv rau 100G modules.Cov neeg siv khoom tuaj yeem xaiv tus nqi zoo tshaj plaws raws li qhov sib txawv ntawm daim ntawv thov scenarios.Rau kev siv luv luv hauv 300m, multimode fiber ntau thiab VCSEL lasers feem ntau yog siv, thiab rau 500m-40km kis tau tus mob, ib hom fiber ntau, DFB lossis EML lasers feem ntau yog siv.

Piv nrog 2.5G, 10G lossis 40G wavelength division systems, 100G optical kis tau tus mob siv digital coherent receivers los qhia tag nrho cov khoom kho qhov muag ntawm cov teeb liab kho qhov muag rau cov hluav taws xob los ntawm theem ntau haiv neeg thiab polarization ntau haiv neeg, thiab siv cov khoom siv hluav taws xob ua kom paub tab. .Tus thawj tswj hwm siv polarization demultiplexing, channel impairment equalization nyiaj, lub sij hawm rov qab, kev kwv yees theem, cov cim kwv yees thiab linear decoding.Thaum paub txog 100G kho qhov muag kis tau tus mob, ib tug series ntawm loj technologies hloov tau tshwm sim nyob rau hauv 100G optical modules, nrog rau polarization multiplexing theem modulation tshuab, digital coherent txais technology, peb tiam super yuam kev kho coding technology, thiab lwm yam, yog li txaus siab rau cov kev xav tau ntawm cov neeg siv. thiab lub sijhawm.Kev xav tau nce qib.

1. 100G optical module

Cov pob khoom tseem ceeb ntawm 100G optical modules feem ntau suav nrog CXP, CFP, CFP2, CFP4, CFP8, thiab QSFP28.Nrog rau txoj kev loj hlob nyob rau hauv xyoo tas los no, kev xa khoom ntawm CFP series cov khoom lag luam tau maj mam txo qis, thiab QSFP28 pob tau yeej qhov kev yeej tag nrho vim nws qhov loj me thiab qis zog siv, thiab feem ntau ntawm cov khoom tshiab 200G thiab 400G kuj siv QSFP- DD pob khoom.Tam sim no, feem ntau optical module tuam txhab uas muag muaj 100G series khoom nyob rau hauv QSFP28 pob ntawm lub khw.

1.1 100G QSFP28 optical module

QSFP28 optical module muaj tib lub tswv yim tsim raws li QSFP optical module.Rau QSFP28, txhua channel tuaj yeem xa thiab txais cov ntaub ntawv txog li 28Gbps.Piv nrog rau CFP4 optical modules, QSFP28 optical modules me me dua li CFP4 optical modules.QSFP28 optical module muaj qhov zoo dua qhov zoo dua CFP4 optical module, thiab lub zog noj thaum lub sijhawm ua haujlwm feem ntau tsis tshaj 3.5W, thaum lub zog siv ntawm lwm cov khoom siv kho qhov muag feem ntau yog nruab nrab ntawm 6W thiab 24W.Los ntawm qhov kev pom no, kev siv hluav taws xob tsawg dua li lwm qhov 100G optical modules.

1.2 100G CXP optical module

Tus nqi sib kis ntawm CXP optical module yog siab li 12 * 10Gbps, thiab nws txhawb nqa kub ntsaws."C" sawv cev rau 12 hauv hexadecimal, thiab Roman tus lej "X" sawv cev tias txhua tus channel muaj qhov sib kis ntawm 10Gbps."P" yog hais txog lub pluggable uas txhawb nqa kub ntsaws.Lub CXP kho qhov muag module feem ntau yog tsom rau ntawm lub lag luam high-speed computer, thiab nws yog qhov ntxiv ntawm CFP optical module hauv Ethernet data center.Technically, CFP optical modules yog siv ua ke nrog multimode optical fibers rau kev xa cov ntaub ntawv luv luv.Vim hais tias lub lag luam multimode fiber ntau yuav tsum tau high-density panels, qhov loj tsis tau zoo tiag tiag rau lub lag luam multimode fiber ntau.

CXP optical module yog 45mm ntev thiab 27mm dav, thiab yog me dua XFP optical module thiab CFP optical module, yog li nws muaj peev xwm muab tau ib tug siab dua network interface.Tsis tas li ntawd, CXP optical module yog tooj liab txuas uas tau teev tseg los ntawm Wireless Broadband Trade Association, uas tuaj yeem txhawb nqa 12 10GbE rau 10GbE, 3 10G txuas xa mus rau 40GbE raws lossis 12 10G Ethernet Fiber Channel lossis wireless 12 * QDR txuas txuas ntawm broadband teeb liab.

1.3 100G CFP / CFP2 / CFP4 optical module

CFP Multi-Source Agreement (MSA) txhais cov kev cai uas kub-swappable optical modules tuaj yeem siv rau 40G thiab 100G network kis tau tus mob, suav nrog cov tiam tom ntej high-speed Ethernet (40GbE thiab 100GbE).CFP optical module txhawb kev sib kis ntawm ib hom thiab ntau hom fibers nrog ntau tus nqi, cov txheej txheem thiab txuas ntev, suav nrog txhua qhov kev tshaj tawm-dependent (PMD) interfaces suav nrog IEEE 802.3ba tus qauv, thiab 100G network muaj peb PMDs: 100GBASE -SR10 tuaj yeem xa 100m, 100GBASE-LR4 tuaj yeem xa 10KM, thiab 100GBASE-ER4 tuaj yeem xa 40KM.

CFP optical module yog tsim los ntawm lub hauv paus ntawm qhov me me pluggable optical module (SFP) interface, tab sis nws loj dua qhov loj thiab txhawb nqa 100Gbps cov ntaub ntawv xa mus.Cov hluav taws xob sib txuas siv los ntawm CFP optical module siv 10 * 10Gbps raws rau kev sib kis hauv txhua qhov kev taw qhia (RX, TX), yog li nws txhawb kev sib koom ua ke ntawm 10 * 10Gbps thiab 4 * 25Gbps.CFP optical module tuaj yeem txhawb nqa ib qho 100G teeb liab, OTU4, 40G teeb liab, OTU3 lossis STM-256 / OC-768.

Txawm hais tias CFP optical module tuaj yeem paub txog 100G cov ntaub ntawv thov, vim nws qhov loj me, nws tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov ntaub ntawv ceev ceev.Hauv qhov no, Pawg Neeg Saib Xyuas CFP-MSA tau txhais ob daim ntawv ntxiv: CFP2 thiab CFP4 optical modules.
