Dab tsi yog CFP
CFP, luv rau C daim ntawv-yam muaj txiaj ntsig pluggable, yog cov khoom siv kho qhov muag uas xa cov ntaub ntawv ntawm cov ntaub ntawv siab, feem ntau muaj peev xwm kis tau ultra-siab tus nqi ntawm 40G, 100G lossis txawm tias 400G. CFP MSA txhais cov khoom sib xyaw cuab yeej sib txawv thiab kev tswj hwm lub ntsiab ntawm CFP optical transceivers ntawm tus nqi sib txawv. CFP yog transceiver uas tuaj yeem txhawb kev sib hloov kub. Nws tuaj yeem txhawb nqa ib qho 100G teeb liab, OTU4, ib lossis ntau dua 40G cim, OTU3 lossis STM-256 / OC-768.
Dab tsi yog CFP transceivers
Txhawm rau kom ua tau raws li qhov xav tau siab nyob rau hauv cov ntaub ntawv sib txuas lus sib txuas, 100G CFP series optical transceivers muaj ntau yam qauv, feem ntau muab faib ua CFP, CFP2, CFP4 thiab CFP8. Nws yuav tsum raug sau tseg tias cov khoom siv kho qhov muag no siv tsis tau sib hloov, tab sis lawv tuaj yeem siv ua ke hauv tib lub cev.
CFP transceiver
Thawj 100G optical transceiver yog qhov loj heev CFP optical transceiver, uas txhawb nqa kis ntawm ib hom thiab ntau hom fiber ntau nrog ntau nrawm, raws tu qauv thiab txuas ntev raws li qhov xav tau, suav nrog txhua lub cev tawm hauv IEEE802.3ba tus qauv Muaj feem (PMD) interface. Nws kuj tseem muaj ntau yam sib txawv ntawm 100G CFP transceivers. 100GBASE-LR4 CFP transceiver tuaj yeem ua tiav 10km teeb liab kis ntawm ib hom fiber ntau, thiab 100GBASE-ER10 CFP thiab 100GBASE-ER4 CFP transceivers tuaj yeem ua tiav 40km teeb liab kis ntawm ib hom fiber ntau. Cov no tuaj yeem siv rau hauv cov ntaub ntawv chaw tsim kho.
CFP2 transceiver
Qhov ntim ntawm CFP2 transceiver tsuas yog ib nrab ntawm CFP transceiver. Nws tuaj yeem txhawb 10 10G raws, 4 25G raws, 8 25G raws thiab 8 50G raws. 100G CFP2 feem ntau siv los ua 100G Ethernet kev sib txuas sib txuas, nrog kev sib kis tau zoo dua li CFP optical transceivers, thiab nws qhov loj me me ua rau nws haum rau kev ua haujlwm siab dua.
CFP4 transceiver
Qhov ntim ntawm CFP4 optical transceiver yog ib-plaub ntawm CFP, thiab muaj cov kev xaiv ib thiab ntau hom kev xaiv. Thaum ntxov 100G CFP optical transceiver ua tiav kev xa xov ntawm 100G txog 10 10G raws, thaum tam sim no 100G CFP4 optical transceiver ua tiav 100G kis los ntawm 4 25G raws, yog li cov kis tau zoo dua thiab cov kev ruaj khov yog qhov muaj zog. Tsis tsuas yog hais tias, lub zog noj kuj raug txo, thiab tus nqi qis dua ntawm CFP2. CFP4 transceiver tuaj yeem pab txhawb 4 10G channel kis, tuaj yeem siv rau 40G / 100G Ethernet kis, kev sib txuas lus deb, thiab lwm yam.
CFP8 transceiver
CFP8 transceiver tau npaj siab rau xyoo 2015. CFP8 yog kev txuas ntxiv ntawm CFP4. Tus naj npawb ntawm cov channel tau nce mus rau 8 channel, thiab qhov loj me tau nce raws li, uas zoo ib yam li CFP2, uas yog 40mm x 102mm x 9.5mm. Piv nrog rau 100G txoj kev sib kis uas twb muaj lawm, CFP8 transceiver tuaj yeem muab ntau tshaj plaub npaug ntawm qhov bandwidth, feem ntau yog 16 kab hluav taws xob 25G cov cim lossis 8 50G cov kab sib tw. Piv nrog kev siv 8 50G rau kev xa mus, 16 25G cov pa hluav taws xob sib tw tau kim dua, thiab 16 25G lasers yuav tsum muaj. CFP8 transceiver muaj kev cog lus nruj thiab kev siv hluav taws xob tsawg. Feem ntau, nws yog kev daws teeb meem nrog qhov chaw nres nkoj siab thiab qhov siab bandwidth.
Cov kev siv ua ke ntawm CFP transceiver
100G coherent optical transceivers yog siv rau cov kab txuas kis tau tus mob ntawm 100G wavelength faib tshuab. Piv nrog rau lwm cov kab ntawm cov kab txuas ntawm cov duab kho qhov muag, nws muaj zoo OSNR kev ua tau zoo, rhiab, kev cuam tshuam kev cuam tshuam, thiab DGD kam rau ua. DWDM wavelength division multiplexing technology siv coherent CFP transceivers yog siv dav hauv 100G cheeb tsam thaj tsam cov cheeb tsam kom tau raws li nws lub siab thiab qhov ntev xav tau.
Xaus
Kev sib xyaw ntawm CFP optical transceiver yog tsim raws li SFP optical transceiver, tab sis nws muab 10 10Gbit / s lossis 4 25Gbit / s cov kab sib txuas cov ntaub ntawv xa mus rau hauv cov kev taw qhia transceiver, nrog cov khoom sib kis tau nce mus txog 100Gbps. Vim nws txoj kev txhim kho tas mus li, tam sim no muaj CFP2, CFP4, CFP8 thiab lwm yam kev cais tawm. 100G coherent CFP transceiver tuaj yeem xyuas kom muaj kev sib kis thaum txo cov hluav taws xob kis tsis tau. Nws yog ib qho kev daws teeb meem zoo rau 100G ntu hauv cheeb tsam cov nroog.
