CFP thiab CFP MSA: Koj Paub Ntau Npaum Li Cas
100G optical module yog ib qho tseem ceeb ntawm txoj kev sib txuas ceev fais fab network. Qee cov neeg hais tias qhov kho qhov muag pom tau muaj ntawm ib tus thawj coj hauv txhua qhov kev sib txuas lus. Txoj kev loj hlob sai ntawm kev siv fais fab kho qhov muag, cov neeg hauv kev lag luam kev sib txuas lus pom tau tseeb. 100G optical module yog suav tias mainstay ntawm lub 5G network, lub lag luam yuav tsum qhia rau peb txhua tus ntawm qhov tseeb tias tus kho qhov muag module tau hloov cov thawj qauv lag luam.
Kev Hais Lus ntawm cov qauv 100G optical module thiab hom, cov qauv lag luam hauv tsev khw feem ntau yog CFP / CFP2 / CFP4 thiab QSFP28. Raws li thaum ntxov nyob rau hauv optical module, CFP yog tam sim no maj hloov los ntawm QSFP28. Tab sis lub ntsiab cai ntawm cov qauv kho qhov muag tsis tau hloov, thiab peb tseem tuaj yeem kawm nws kom nkag siab txog 100G qhov muag khoom module. Niaj hnub no peb yuav tham txog seb qhov CFP yog thiab qhov 100G CFP ntau qhov kev pom zoo (MSA).
CFP Optical Transceiver Yog Dab Tsi?
Tsim ntawm feem ntau rau 100G kev ua lag luam, CFP optical transceiver yog tsuas rau qhov ntev ntev interfaces thiab ib hom ntawv hom fiber ntau. Nws yog 120mm ntev thiab 86mm dav. Nws yog tib yam ntev li 10G XENPAK optical transceiver tab sis ob zaug li dav. Nyob rau tib lub sij hawm qhov kho qhov muag pom tau zoo thermal kev ua tau zoo, ua rau nws siv cov hwj huam siv zog me me.
Gigalight muaj peev xwm muab ntau hom CFP optical transceivers: CFP 100GBASE-SR10, CFP 100GBASE-LR4, CFP2 100GBASE-SR10, CFP2 100GBASE-LR4, thiab 100GBASE-SR4 CFP4. Dhau li, nws yuav tso tawm qhov tseeb 100G CFP2 ER4 / 100G CFP ER4 rau Lub Ib Hlis Ntuj, xyoo 2018. Cov kev hloov kho qhov muag no yuav ua tau ntau yam kev kis tau los ntawm kev sib txuas nrog ntau hom fiber ntau tshaj.
| Module | Txuas Hluav Taws | Kis Qhov Nruab Nrab |
| CFP 100GBASE-SR10 | MPO | 400M |
| CFP 100GBASE-LR4 | Dual LC | 10KM |
| CFP2 100GBASE-SR10 | MPO | 400M |
| CFP2 100GBASE-LR4 | Dual LC | 10KM |
| CFP4 100GBASE-SR4 | MDIO | 100M |
Lub hauv paus chiv keeb thiab kev thov ntawm 100G CFP Optical Module MSA
CFP MSA yog cov ntsiab lus siv rau 100G Daim Ntawv Txiav Txim Sib Zog Muaj Nqis. Nyob rau hauv lub Peb Hlis Ntuj 2009, qhov kev pom zoo tau muab tshaj tawm rau CFP module los ntawm Finisar, Opnext thiab Sumitomo los txhais kev kub ceev Ethernet rau kev siv 40G thiab 100G thiab pab txhawb ntxiv rau tiam tom ntej. Nyob rau lub Rau Hli 2010, CFP MSA cov neeg ua haujlwm hauv ib tus tswv cuab tshiab, AVGO, thiab tso tawm ntau qhov kev pom zoo rau ib daim ntawv tshiab (Rev 1.4).
CFP MSA qhia txog daim duab txheej txheem ntawm CFP module. DMUX thiab MUX nyob rau hauv qhov chaw kho qhov muag ua qhov kev kho qhov muag thiab qhov sib txuam. Lub WDM (wavelength division multiplexing) technology muab ntau tshaj qhov kev xav tau ntawm ntau lub wavelengths mus rau ib hom fiber ntau optical fiber. Tus qauv yuav ua haujlwm ntawm ITU WDM wavelength. Tus qauv txais ib qhov kev sib txuas ntawm ib tus tib neeg, uas txuag tau 2 × 2 (N-1) qhov muag fibers. Hauv kev siv tswv yim, qhov kis tau tus mob ntawm ib hom kev kho qhov muag fais fab tuaj yeem siab tshaj 10km. Hauv schematic, N nruab nrab yog cov naj npawb ntawm optical channel, M nruab nrab ntawm cov xov tooj ntawm Circuit Court raws. Feem ntau, M thiab N yog tsis sib npaug. Qhov hluav taws xob interface ntawm tus qauv yog 10 Gbit / s. Yuav kom siv 100 Gbps tus nqi sib kis, 10 hluav taws xob interfaces yuav tsum tau los txhawb qhov no. Tus naj npawb ntawm hluav taws xob interfaces yog 10 rau 100GBASE-LR4 thiab 100GBASE-ER4, thiab plaub rau 40GBASE-FR.
100G CFP Optical Module Hardware Txhais
CFP module muaj txog li 148 pins, muab faib rau hauv qab thiab saum toj kawg nkaus ntawm tus qauv hluav taws xob interface. Tus tswj tuav lub tshuab yuav nyeem cov lus tswj thiab qhov xwm txheej los ntawm qhov hluav taws xob teeb liab, uas muaj 6 tswj lub pins, 5 lub xov tooj hluavtaws pins (xws li RX_LOS) thiab 8 MDIO tswj interface pins. Optical interface ib sab yuav muaj SC, LC, thiab MPO connector daim ntawv.
Tom qab nkag mus rau tus tswv tsev, CFP kho qhov muag modules tuaj yeem ua qhov kev hloov sij hawm raws li kev ntsuam xyuas. Daim duab txheej txheem hauv qab no yog rau tus qauv hauv txhua lub xeev thiab lub xeev cov teeb liab uas muaj feem nrog lub chij hloov.
CFP module operating temperature tsis teev: 0 ℃ to 70 ℃. Modules tuam txhab uas muag yuav tsum kuaj qhov kev ua tau zoo ntawm cov qauv no hauv ob qho chaw kub thiab tau los xyuas kom meej tias cov kev hloov hauv cov kub txhua yam tuaj yeem ncav cuag lub phiaj xwm. Tus coj lub cev kuj xav tau los ua kom muaj qhov txias tsim nyog kom paub meej tias lub module ua haujlwm hauv qhov kub thiab txias.
CFP SMA kuj qhia txog qhov loj me me, qhov nyhav, lub zog ntawm lub zog thiab lwm yam, nrog rau cov mainframe txuas nrog tus qauv ntawm txhua yam khoom siv thiab cov khoom hluav taws xob cov ncauj lus kom ntxaws.
